What is inside a Blackhole?
The singularity at the center of a black hole is the ultimate no man's land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down. And it doesn't really exist.
What could be inside a black hole?
By their calculations, quantum mechanics could feasibly turn the event horizon into a giant wall of fire and anything coming into contact would burn in an instant. In that sense, black holes lead nowhere because nothing could ever get inside. This, however, violates Einstein's general theory of relativity.
Is there anything in a black hole?
Don't let the name fool you: a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City.
Is there life inside a black hole?
The short answer to the question is no because nothing can escape a black hole once it passes through the event horizon. There is, however, a theoretical possibility you can live inside of a black hole if you happen to enter a supermassive one.
Is Earth in danger of a black hole?
Since this black hole already weighs a few million times the mass of the Sun, there will only be small increases in its mass if it swallows a few more Sun-like stars. “There is no danger of the Earth (located 26,000 light years away from the Milky Way's black hole) being pulled in.
What's Actually Inside A Black Hole?
Does time stop in a black hole?
Time does stop at the event horizon of a black hole, but only as seen by someone outside the black hole. This is because any physical signal will get infinitely redshifted at the event horizon, thus never reaching the outside observer. Someone falling into a black hole, however, would not see time stop.
Is there a white hole?
The short answer, unfortunately, is no. White holes are really just something scientists have imagined — they could exist, but we've never seen one, or even seen clues that one may exist. For now, they are an idea. To put it simply, you can imagine a white hole as being a black hole in reverse.
Do wormholes exist?
Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They've never been seen, but according to Einstein's general theory of relativity, they might exist.
What's at the end of a black hole?
The boundary of a black hole is its event horizon. It is not a physical edge. It's just a point in space beyond which it is impossible to escape the black hole's gravity. Once anything falling into the black hole passes the event horizon, it can never leave the black hole again.
Can you create a black hole?
To make a black hole, one must concentrate mass or energy sufficiently that the escape velocity from the region in which it is concentrated exceeds the speed of light. Some extensions of present physics posit the existence of extra dimensions of space.
Who destroyed the universe?
9 THANOS. In Marvel: The End, Thanos comes into control of the Heart of the Universe, an energy source so powerful that he becomes the universe itself.
Do black holes eat space?
Is it possible for a black hole to "eat" an entire galaxy? No. There is no way a black hole would eat an entire galaxy. The gravitational reach of supermassive black holes contained in the middle of galaxies is large, but not nearly large enough for eating the whole galaxy.
Is time Travelling possible?
Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.
How many universes are there?
In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.
Does gravity bend time?
The gravitational field is really a curving of space and time. The stronger the gravity, the more spacetime curves, and the slower time itself proceeds.
Why do black holes exist for kids?
Black holes are formed when giant stars explode at the end of their lifecycle. This explosion is called a supernova. If the star has enough mass, it will collapse on itself down to a very small size. Due to its small size and enormous mass, the gravity will be so strong it will absorb light and become a black hole.
What is on the other side of a black hole?
The discovery of light from the other side of a black hole was predicted by Einstein's theory of general relativity. But it has never actually happened before, and the discovery marks the first time that light has ever been directly observed coming from behind a black hole.
What happens if a black hole and a white hole collide?
For reference, that's 3 million times larger than Earth. So if a white hole and black hole collided, we'd have a massive black hole roaming around the Universe, destroying everything in its path.
Will the sun become a black hole?
Will the Sun become a black hole? No, it's too small for that! The Sun would need to be about 20 times more massive to end its life as a black hole.
What happens if two black holes collide?
It is possible for two black holes to collide. Once they come so close that they cannot escape each other's gravity, they will merge to become one bigger black hole. Such an event would be extremely violent. Even when simulating this event on powerful computers, we cannot fully understand it.
Will the universe end in 100 trillion years?
(100 trillion) years from now, star formation will end, leaving all stellar objects in the form of degenerate remnants. If protons do not decay, stellar-mass objects will disappear more slowly, making this era last longer.
