What Will Happen to Earth When Our Galaxy Collides With Andromeda?

We are awaiting an epic war between our galaxy and the Andromeda Galaxy, which is heading towards us at a speed of 250,000 mph.

Astronomers predict that Earth will be besieged during the largest galactic event in its history. The two giant galaxies will collide with each other, after 3.7 billion years.

Experts believe that the Earth will – fortunately – survive the collision, although it will be affected.

The collision will appear directly in front of us, changing the shape of the sky at night to be different from anything a person has seen before.

Join our future journey to see how it will be:
Galaxy

Away from the city lights and on a clear night, this is how the earth looks like.

You can see – during certain times of the year – the Andromeda Galaxy – surrounded by a yellow ring at the bottom – next to the bright range of our Milky Way.

Andromeda now separates us from 2.5 million light-years away, and when they collide with our galaxy in less than 4 billion years, a catastrophe that will last for billions of years will befall them, tearing them apart to form a new galaxy.

And the creatures that live on Earth just before the collision will have a very beautiful view.

On the left, you see Andromeda as you approach the Milky Way driven by the forces of mutual attraction.

The two galaxies will be affected by the collision quickly, after only 250 years after the collision, only the ruins of what was once galaxies will remain.
Galaxy

but that is not all.

The battle will last billions of years until the two black holes in their core approach close together.

One billion years after the cosmic massacre, the night sky will be blazing at the glow of the new elliptical center of the galaxy – if the Earth were present then the sun would swallow it up a billion years from now.
Galaxy
Because galaxy fusion takes billions of years, astronomers comb the sky in search of different phases of epic battles.

Below is a photo was taken by the Hubble Telescope of two spiral galaxies in an early merger phase.

This is a different set of galaxies, one of which has been stretched and distorted by the attractiveness of the other galaxies.

What Will Happen to Your Brain While You Are on the Way to Mars

Human On Mars
Initial studies indicate that it does not bode well.

NASA aspires to send a manned flight to Mars during the next twenty years, but a study indicated that it will be more dangerous than we expect, new data showed that exposure to cosmic radiation for long periods may greatly affect seriously the cognitive and cognitive abilities of astronauts.

University of California researchers in Irvine, USA simulated the conditions of deep space on a group of mice in the laboratory by exposing them to explosions of accelerated particles, which are similar to cosmic waves. The results indicated that the radiation-exposed mice were disorganized and frequently forgotten, in addition to the fact that their response and reaction so slow.

“It is not good news for the pioneers who were allegedly sent to Mars on a two-way trip for two to three years,” says Charles Limoli, a radiotherapy professor at a press conference, and adds: “a decrease in performance, a deficit in memory, loss of consciousness and focus during the trip All of this may affect the mission’s primary tasks, as well as the fact that long-term exposure to these particles may have severe consequences for lifelong perception.

Cosmic rays, a product of galactic eruptions like a supernova, are highly charged particles that can easily penetrate the shuttle’s structure and human bones and cause massive damage to the central nervous system of the body.

On our planet, the magnetosphere guarantees the protection of the Earth’s surface from this dangerous radiation, but the thin atmosphere of Mars cannot protect its surface in that quality, just as the Earth’s magnetosphere extends to about 56,000 km above our heads, meaning that it also protects the astronauts from the cosmic radiation.

In a study, published on Science Avances conducted at NASA’s Space Radiation Laboratory by the Brookhaven National Laboratory in New York, a group of genetically engineered mice suffered burns due to a bundle of oxygen ions and titan accelerated at two-thirds of the speed of light, the same type of ions found in cosmic rays. Hungarian.

These mice were genetically modified to possess radioactive neurons, making it easier to monitor changes in the level of their brains.

Six weeks after exposure, mice lost from 30 to 40 percent of their dendrites – the branches between the neurons responsible for transmitting electrical signals – compared to the reference group.

Exposure to cosmic radiation leads to permanent deterioration of neuronal ramifications, this deficiency is associated with mental disorders such as in those who suffer from Alzheimer’s or similar neurological diseases.

Cognitive and cognitive tests were then performed on both groups, and new bodies were added among those familiar to mice. It was observed that those exposed to radiation were disorganized and lost their curiosity compared to the reference group.

If astronauts do the same, their response speed and their ability to retrieve information will be affected.

During the alleged trip to Mars that will last from two to three years, any effect of exposure to cosmic radiation will find the time to appear, the ability of the astronauts to complete the task and do research experiments in addition to their health of their knowledge, all of this will be in danger, Limoli and his team do not think that That level of turmoil will lead astronauts to destroy their shuttle, but at least sabotage their experiences.

The brain is a complex organ and long-term studies are required before we understand the full effect of cosmic rays on it, and we can separate by saying whether these disorders and changes observed in mice are chronic or not.

What Happens If a Nuclear Bomb Explodes in Space

Nuclear Bomb Explodes in SpaceThe “Mushroom Cloud” image is one of the most well known and terrifying scenes too. Although nuclear threats have declined over the past decades, there was a time in the twentieth century when fascination and fear of nuclear weapons caused everyone around the world to do somewhat insane matters.

The countries of the world that possess nuclear weapons (especially Russia and the United States of America) have tested these weapons underwater, in the mountains, in the air, and even in space!

Maybe we can imagine what these explosions will look like, and what their impact will be, but what about the last explosion? What would happen if a nuclear bomb exploded in space?

During the most dramatic stages of the Cold War, Russia and the United States were testing nuclear bombs in all directions, and all eyes were watching the sky because of the fear of a wide-ranging nuclear weapon, or nuclear warheads guided by satellites.

The United States launched a series of tests, codenamed “Fishbowl Project” which was a high-level nuclear weapons test.

“Starfish Prime” was the most surprising and historic test of this project. On the ninth day of July 1962, a 1.4 megaton nuclear bomb exploded, approximately 250 miles above the ground.

What would happen if a nuclear bomb exploded in space?

First, there was no cloud of a mushroom in its typical form or even a burst wave due to the absence of an atmosphere in space (this causes most of the damage to the planet as a result of a nuclear bomb explosion).

Instead, there was a tremendous flow of heat and light, and not only that but rather high-intensity radiation in the form of gamma and X-rays produced without an atmosphere impeding their path. The explosion took a spherical shape, and the wave of radiation and light expanded to illuminate the sky.

On the surface of our planet, it was possible to see bright twilight lights thousands of miles away minutes after the explosion, because the charged particles from the explosion had immediately started interacting with the Earth’s magnetic field.

It can be imagined in the form of the “Aurora Borealis”, more commonly known as the Northern Lights, but it has spread kilometers over the Pacific Ocean. The streaks of light and the flow of charged particles would last for hours and even days after the explosion (depending on its size).

Also in the nuclear explosion, there is a small portion of the debris that can ignite in the Earth’s outer atmosphere, and heavy ions absorbed by the atmosphere’s particles. But in fact, these additional radioactive particles are useful in certain ways (to this day), and we’ll explain that in the next paragraph.

Are there other effects of a nuclear bomb exploding in space?

Perhaps the most disturbing thing about the enormous amount of radiation that will collide with the Earth’s atmosphere is the effect of the explosion on the electromagnetic signals within a huge area beneath the explosion.

These high-charge, fast-moving electrons will form a small but extremely powerful magnetic field, called an “Electromagnetic Pulse” (EMP).

Arguably you have seen this more than once in science fiction movies; the electromagnetic pulse bomb cuts all electronic communication within a specific space (almost the most famous example of this is the Matrix movie).

In the case of the aforementioned “Sea Star” test, the force of the explosion caused blackouts hundreds of miles away in Hawaii, damage to street lights, malfunctions of radars and navigation systems, and a complete cessation of electronic communications.

Hawaiian residents may have taken it as an unintended consequence, but it showed scientists and researchers the power that a nuclear bomb had exploded in space.

It can damage the infrastructure of a country without even destroying it financially. Now put in your account the size of the bomb used in the “Sea Star” test, which is 1.4 megatons.

Knowing that some of the largest nuclear warheads that were built were hydrogen bombs with a capacity of 50 megaton tons, which means that they are 35 times stronger.

Now imagine the number of lights of the aurora borealis that you could see if a bomb of this force exploded in space, and think about the large-scale technological devastation caused by an electromagnetic pulse large enough to completely disable Texas!

Ultimately, for the long-term effects of a nuclear weapon exploding in space, the radioactive materials that fall into the atmosphere will not go anywhere. But in reality, it will fade across the entire planet.

We can now accurately measure these additional molecules resulting from a nuclear explosion, as a way to know the history of things like trees, wine, and animals.

While this can be a useful thing about nuclear tests in space, it does not make the process as a whole logical or rational.

A few nuclear detonation tests were conducted at high altitudes during the 1950s and also 1960’s, but in total, more than 2,000 nuclear detonations were performed on the planet between 1945 and 1998.

The picture is clear. Whether this happens on the ground or in space, the news of nuclear explosions is not good at all!

What Will Happen to Your Body in Space Without a Space Suit

without space suit
Have you ever wondered what would happen to your body in space without a spacesuit? Will the subject be as dramatic as the movies portray us? Will you explode? Can you survive?

On Earth, we live in a very relaxing environment thanks to the atmosphere that protects us from the sun’s UV rays, regulates our temperature, and maintains appropriate atmospheric pressure.

But the vacuum of space is much more aggressive.

Without this thick atmosphere cover, we would be exposed to all sorts of different dangers.

The most serious risk we face when exposed to outer space is lack of oxygen and peat.

Pemphigoid is the appearance of gas bubbles in the body fluids due to the lack of external air pressure.

The pressure in the vacuum of space is so low that the boiling point of your body fluids becomes lower than your body’s normal temperature (37 ° C), which results in gas bubbles in your body fluids, which may cause you with atrocious risks.

It will swell ugly and may even double in size, but you won’t burst because your skin is stretchy.

Your blood will not boil.

But, of course, you will suffer a great deal of pain and the blood flow inside your body will be hindered.

As we mentioned earlier, the next big danger is hypoxia.

After about 15 seconds, your body will have used all the oxygen inside and you will lose consciousness.

Some of you may think, “But I can hold my breath for minutes!”

The situation in space is a little different from what it is on the ground because of the lack of external pressure, and if you hold your breath in space without a spacesuit, you will be in big trouble.

This is because any extra air will quickly expand and cut your lungs.

After losing consciousness, you’ll usually survive a few minutes maximum before you die.

Of course, there are all those harmful UV rays from the sun that will cause you to have a terrible sunburn.
x-rays - Ultraviolet rays
Ultraviolet rays and other high-energy photons (X-rays and gamma radiation) will also seriously harm your DNA, leading to mutations that may cause cancer (if you survive later), if you are in space close to the sun, from Venus’s side Or Mercury, for example.

If you were in the cold space of Jupiter and Saturn, it would not freeze immediately as the vacuum would cause heat to move away from your body very slowly.

What Will Happen to Your Body in Space Without a Space Suit?

So in short, you will swell, burn, lose consciousness, and your lungs will explode.

But do not worry, if you get involved in a difficult situation like this one day, you will have a minute or two minutes to be saved before you die, do not lose hope.

What If Neil Armstrong and Buzz Aldrin Didn’t Return From the Moon?

NASA moon-landing mission
On July 20, 1969, Buzz Aldrin and Neil Armstrong became the first human to walk on the moon, and then US President Richard Nixon became the first human to communicate with the moon via a landline, on the other hand, and through broadcast TV (by contacting the spacecraft landing on the moon by the NASA mission controller in Houston); Nixon told the astronauts of the Apollo mission that the whole world was proud of them and continued his speech by saying: “Thanks to what you have done, the heavens are now part of the human world.” At the same time, the US President was ready for further contact with my wife Neil Armstrong and Aldrin who could have become widows.
Even after the lunar module landed in an area called the Sea of Tranquility in night, Neil Armstrong and Aldrin were not guaranteed safe return to their lunar module once again, where their colleague Michael Collins awaited them, far from their return to Earth.
With that in mind, then-US President Richard Nixon asked William Safire, a speechwriter, to write a contingency plan (in case of any disaster on the moon).
As Savir made clear in his 1999 meeting with the Meet The Press program, driving the lunar module back into orbit to meet the main vehicle was one of Apollo 11’s most important mission targets, while the Apollo 10 crew had previously tried to drive the lunar module 14.4 kilometers away From the surface of the moon, Apollo 11 astronauts have faced unprecedented challenges while returning the spacecraft back to orbit.
And he went on to meet with Meet the Press: If they can’t do that (i.e. return to orbit), they will have to be abandoned on the moon, left to die there, or they either starve to death or commit suicide.
Had that happened then, he would have been forced by NASA to cut contact with astronauts condemned to stay there, and to instruct President Nixon to report to the world what had happened.
The Sapphire plan he sent to the White House chief of staff to US President Nixon included H.R. Haldeman, on July 18, 1969, participated in the news media 30 years later, and was instructed on how Nixon summoned the widows of the astronauts first before giving a speech to the nation explaining how he “spent the fate of the men going to explore in peace, who will keep The moon to rest in peace. ”
Then he continued in the speech: “These brave men – Neil Armstrong and Aldrin – knew that there was no hope for their return, but they also knew that there was hope for humanity through their sacrifices.”
He then continued writing that many people would follow in the footsteps of the Apollo astronauts and they will certainly find their way home, but Aldrin and Neil Armstrong “were the first, and they will always be at the forefront of our hearts.
In the end, the speech was concluded with the words: “For everyone who looks at the moon in the coming nights, he will know that there is a corner from another world, which is the human race forever.”
Despite some setbacks that occurred while on the move in the cockpit of the lunar module, one of the astronauts mistakenly broke the circuit breaker controlling the vehicle’s engines, but in the end Aldrin and Neil Armstrong managed to meet with their colleague Collins successfully on a surface the moon and then the three returned to Earth safely.
Fortunately, the president no longer needs to make a dramatic statement of Sapphire, yet you can still read the full speech below, with permission from the museum and library of former US President Richard Nixon.

What If We Build Cloud Cities on Venus?

What If We Build Cloud Cities on Venus?

What If We Build Cloud Cities on Venus?

Earth may not be here forever. A huge solar flare, an asteroid impact or a local burst of gamma rays – everything could annihilate us forever.

If we are looking for a place to escape, our solar system contains a planet that looks a bit like Earth, although we do not know much about it. There could even be microbial life. No, it’s not Mars, it’s Venus.


Not only are Earth and Venus about the same size, but they also have identical interiors with partially liquid nuclei, coats, and scabs. Yet Venus happens to be the most hostile terrestrial planet in the solar system.


But if I told you that you can explore this hot planet without ever setting foot? Venus is not a place where you would like to land. Thanks to its dense atmosphere and its turtle-shaped rotation, the surface temperature of Venus remains at 462 ° C.


The atmospheric pressure of the planet is 92 times higher than that of the Earth. Because of this high pressure, everything that enters the atmosphere of Venus is immediately crushed before reaching the volcanic surface of the planet.


In such extreme weather conditions, it is too dangerous to try to land on Venus. But we would not need to go down there.


Above the dense layer of clouds, Venus is not so bad. The atmospheric pressure is similar to that of the Earth. The gravity is slightly lower. The temperature reaches 75 ° C. Although it is a little hot, it remains feasible.


How could we do it? Well, do not start small. According to NASA’s plan to explore Venus, we would send two spacecraft to our destination.


Venus is the closest planet to Earth. That’s why it would only take 100 days for the craft to arrive there.


One of the ships would be run by robots. He would carry a special airship that would fly into the atmosphere upon his arrival.


This airship would begin to inflate with helium. As helium is lighter than air, the airship floats, gravitating around 52 km above the planet.


The second spacecraft would have a crew of two. It would be connected to the airship in orbit around Venus.


The crew would have 30 days to complete all environmental assessments. After that, they would come off the airship and start returning to Earth.


The return trip would take about 300 days due to the strong gravitational pull of the Sun. Even with that, the complete mission would not take more than 450 days.


After analyzing the information from the first mission, we would start planning our next trip to Venus. But this time, we will stay there longer.


The next crew would have a year to study the planet and its atmosphere. One of the things they would look for on Venus would be life. Scientists believe that because microbes on Earth can thrive in acidic conditions surrounded by sulfur, there could be life in the Venusian atmosphere.


After the end of the second mission, we would prepare to stay on Venus permanently. We would begin by building cloud cities in which future generations would live and hopefully continue to explore the space and its origins.


They could even solve the pressure problem. From there, they terraform the planet and settle on the Venusian surface, formerly hostile.

What happens if you shot a gun in space?

What happens if you shot a gun in space?
The  fire cannot be ignited in oxygen-free space, but a gun can fire bullets into space, where modern ammunition has its own oxidizer, a chemical ignited by gunpowder, and can be fired anywhere in the universe even if it is not contain oxygen, but the shape of the smoke coming out after the bullet differs in space.
Imagine that you float freely in the intergalactic spaces, just you and your gun and one bullet, and then you fire this bullet what will happen?
Newton’s third law: If an object a exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.
So According to Newton’s third law, the force used to fire the bullet will generate other equal forces opposed to it. A few per second because your mass is larger than the bullet.
But what will happen to the bullet?
Don’t wonder about the bullet’s fate in space. The bullet will be in near space, making it stop completely after 10 million light-years.
But beware you may kill yourself!
Yes, you can kill yourself in space the bullet was fired horizontally when you are in the orbit of a planet where things revolve around it and which is in a constant state of free fall, it will orbit the planet to return to the place where it was launched. Where you can settle in your back!

What if the moon disappears ?

What if the moon disappears ?
The moon is not just a beautiful face we mingle with during the night. It also helps to direct ocean currents, tidal movement, atmospheric movement and climate, and even the axis of the Earth.

So, what can happen to the Earth, and to us, if the Moon suddenly disappears without warning? Can we survive? Unfortunately, the answer is probably negative.
As soon as the moon disappears, we will immediately notice that the night is becoming darker. This is because the moon’s surface reflects the sunlight, which shines a little night sky. Without this indirect flare, crossing unnaturally lit places, such as rural roads or camping sites in the woods, will become more difficult and risky at night.

The sudden disappearance of the moon will also cause animal confusion. It is not surprising, but its results for the question posed by this article are interesting. Without the moon, these animals will have difficulty finding food. On the other hand, rodents tend to hide more when the moon light is bright and it becomes easy for predators to stumble upon them. Without the moon, these animals will multiply dramatically. “I think we may see some changes in the numbers and spread of species in ecosystems,” says Laura Pro, lead author of the study and a wildlife ecosystem specialist at the University of Washington.

Another immediate difference is the tide. Since the distance between us and the moon presents the Earth for the gravitational effect of the moon. Although it is not strongly the earth’s earthly influence, which keeps the moon in orbit, it is sufficient to move the oceans back and forth, in the known tide phenomenon. Without the moon, the phenomenon will slow to about a third of its current velocity, according to Matt Siegler, a scientist at NASA’s Jet Propulsion Laboratory and a lunar probe operator. The tidal movement will not stop completely, given the gravitational influence of the sun on the oceans, but it will not be even close to the moon.

This two-thirds decline will significantly alter coastal ecosystems, potentially destroying a large number of them, disrupting the flow of energy, water, mineral materials and other resources. There are many ecosystems, such as crabs, snails, crustaceans, clams, starfish, seaweed, and algae, all dependent on the daily movement of water. . In contrast, these ecosystems provide food for migratory and domestic birds, as well as wild mammals such as bears, raccoons, and deer.

Tidal movement also helps to move ocean currents, which in turn moves global weather patterns, and distributes warm water and rain showers all over the planet. Without it, regional temperatures will be milder and more violent weather events will emerge, according to Jack Burns, who heads the Discovery and Space Science Network at the University of Colorado at Boulder. He says that the moon’s gravity not only moves the ocean’s water, but moves the particles into the atmosphere in the same way.

In short, large satellites have the potential to stabilize the climate, which is one of the key things scientists look for when determining which planets can contain life. “The planet outside the solar system needs a good-sized moon so that patterns The weather is quiet enough for the emergence of civilizations similar to our civilization ” Some researchers consider that life is impossible without the presence of this heavenly body.

The disappearance of the Moon may cause even more significant changes, albeit at a much longer time. For example, the disappearance of the moon’s impact, which proves the Earth’s current state, could alter the Earth’s axis significantly over time. It may move from a state of complete rectitude, and without classes at all, to intense Milan with violent seasonal changes in the weather and ice ages during a period of only a few hundred thousand years.

What If The Black Hole Delete the universe?

What If The Black Hole Delete the universe?
They are massive and extremely dense. They rip apart anything and everything that gets close to them.
We can’t see black holes. But we know they have the destructive power to wipe everything out of existence.
Before we get to the part where a black hole erases the Universe, let’s make something clear.
The universe is a giant supercomputer processing information. Without information, there can be no Universe.
WHAT IS INFORMATION?
In physics, information is the property of a specific state of a particle.
I know, it sounds confusing. Here’s a simpler way of looking at it.
What If The Black Hole Delete the universe?
This is a carbon atom.
 A bunch of these can be arranged to make a hard diamond. But if you changes the arrangement of atoms, you can get soft graphite. The basic building blocks are the same. It’s information that makes them different. In quantum mechanics, information is like the energy it can’t disappear into nothingness. So how in the Universe can one black hole do the impossible?
THE BLACK HOLE INFORMATION PARADOX
Black holes act like monstrous cosmic trash compactors. They squeeze stars, planets and unfortunate astronauts who cross the event horizon into a microscopic point.
So what happens to the information about every particle that a black hole consumes? Since information can never be destroyed, it has to be stored somewhere inside that black hole, right?
Our original understanding of black holes assumed that everything that disappeared in the black hole, stayed in the black hole.
The moment an object passed the event horizon, it got crushed into the density of the black hole. The information about it could never be retrieved again. That’s what we thought before Stephen Hawking introduced Hawking radiation. Hawking realized that black holes aren’t static. Rather, they release their mass and energy back into the Universe particle by particle, until there is nothing left. So does that mean the information within a black hole can somehow escape with the black hole’s outgoing radiation?
Not quite. The black hole doesn’t preserve the information it consumes. It chaotically mixes it together with other bits of information, making it impossible to recover 
THE INFORMATION IS LOST!!
If the information can be lost, that would mean that black holes can eventually delete the Universe.
FOREVER.
But there is a possibility that the black hole doesn’t delete the information. It may be hiding it in a baby universe a small self-contained part of the universe that branched off of ours. The information wouldn’t technically be lost, but we wouldn’t be able to interact with it. Another possibility is that black holes can encode the information, according to the holographic principle. If you were to get trapped inside a black hole, you’d still experience three-dimensional space. For us looking at you from the outside, you’d appear stretched on the flat surface. Just like a hologram. That would mean that the information paradox is resolved, and we don’t need to rewrite the laws of physics.
But we’d have to rethink our understanding of reality. The universe could be a 3D image projected off a 2D surface.
And you may be a hologram on the surface of a black hole. And the best part the black hole couldn’t delete the Universe after all.

What If Earth Was Near the Center of the Milky Way?

What If Earth Was Near the Center of the Milky Way?
That’s our home galaxy,the Milky Way.
We can see it from Earth because we live right on the outskirts,far away from all the fun stuff happening in its center.
Could we survive near that center?
How would our sky look like ?Would we fall into a black hole ?
We know that The Milky Way is huge ,about 100.000 light-years across ,it has four large,spiral arms encircling its center; that makes it a barred spiral galaxy,just like most galaxies in the observable universe.
If the Earth packed up its belongings and moved to the heart of the Milky Way,things would be looking pretty bleak for the survival of any kind of life on the planet.But not because of the Milky Way’s super-massive black hole…
The Earth is located in a quiet neighborhood in one of the smallest spurs of the Milky Way-the Orion Arm.We’ve got approximately 27.000 light-years between us and the galactic center.It’s a comfortable spot to live in.
 The temperatures on Earth are just right to sustain life. And there aren’t too many space hazards that could wipe out our existence.Living anywhere near the center of the Milky Way would be different , it would depend on what part of that center the Earth had the misfortune to occupy.The closer you get to the heart of the galaxy, the tighter the stars are packed together.Because of this high star density,the Earth would  be blasted,with a lot more radiation than what the Sun throws at you right now.Under these circumstances, the odds of life ever evolving would be pretty small.But if the Earth moved to the center together with all its inhabitants, you’d find yourself very unlucky.Earth’s magnetosphere wouldn’t be able to protect you from space radiation blasting from all directions.
 This could change the Earth’s climate, and cause everything on the planet to either mutate or die.If you lived,you biggest concern would be a close encounter with a supernova.A supernova occurs when a massive star collapses releasing radio waves, X-rays,cosmic rays and gamma rays into space. For all we know, one massive stellar body could throw the Earth out of the Sun’s orbit.
Our planet would be surrounded by foreign stars until one of them exploded in a supernova and wiped us out for good. But it would look spectacular from Earth,if only for a brief moment.There’s another big hazard that lies within the Milky Way’s center a super massive black hole called “Sagittarius A*” if getting sucked into a black hole isn’t on your to-do list,consider yourself lucky.
The Earth might stay enough from it that we wouldn’t get engulfed by this cosmic beast. But we could get close enough to get caught in the black hole’s orbit. At a distance of 20 billion km(12 billion mi)from the black hole’s event horizon,the Earth could develop a speed of 25 million km/h (15.5 million mph).That’s over 230 times faster than the speed our planet is moving at right now.
Would that mean strong winds?
More disasters?
Would you fly off into space?
It sure wouldn’t be good for you,or anything else on the Earth’s surface.The Earth is perfectly designed to be right where it is. It can survive on the outskirts of the galaxy, but you wouldn’t want it to be anywhere else. The most dangerous place for a planet to be located is anywhere near the center of a galaxy-any galaxy.
