A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can’t see black holes.
What is a black hole answer?
A black hole is an extremely dense object in space from which no light can escape.
What exactly is black hole?
Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole’s gravity. Such a burst flings star matter out into space but leaves behind the stellar core.
Is a black hole 2 or 3 dimensional?
This idea aligns with Einstein’s theory of relativity, which describes black holes as three dimensional, simple, spherical, and smooth, as they appear in that famous image. In short, black holes “appear” as three dimensional, just like holograms.
Can you see a black hole?
But you won’t be able to see the black hole itself; the massive object has such a strong gravitational pull that nothing — not even light — can escape it. Astronomers discovered this black hole while studying what they thought was just a binary star system, or two stars that orbit a common center of mass.
What happens in a black hole NASA?
A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape. The strong gravity occurs because matter has been pressed into a tiny space. This compression can take place at the end of a star’s life. Because no light can escape, black holes are invisible.
Where do things go in a black hole?
It is thought that the matter that goes into a black hole gets crushed into a tiny point at the center called a “singularity”. That’s the only place that matter is, so if you were to fall into a black hole you wouldn’t hit a surface as you would with a normal star. Once it’s there, it’s there.
What happens if a person goes into a black hole?
The gravitational attraction of a black hole is so strong that not even light can escape it. Spaghettification: A black hole would stretch an astronaut’s body into a thin ribbon, since the gravity pulling on their feet is so much stronger than on their head.
What would a black hole do to Earth?
If Earth got close enough, the side nearest to the black hole would begin stretching toward it. Our atmosphere would start to be vacuumed up. If Earth managed to fall into the orbit of the black hole, we’d experience tidal heating. The strong uneven gravitational pull on the Earth would continuously deform the planet.
Could a human survive a black hole?
Even light, the fastest-moving thing in our universe, cannot escape – hence the term “black hole.” The radial size of the event horizon depends on the mass of the respective black hole and is key for a person to survive falling into one. A person falling into a supermassive black hole would likely survive.
Will a black hole come to earth?
Thankfully, black hole collisions are likely rare. In the most “optimistic” scenario — optimistic by the scientists’ standards, that is, so populating the galaxy with the maximum number of black holes — there might be one collision or so every billion years, according to the paper’s calculations.
Does time exist in a black hole?
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.
How many dimensions are black holes?
Black holes may be two-dimensional, but contain information about three dimensions, just like a [+] As material falls into the black hole, information would not be lost. Instead, it is preserved in the surface area (or the event horizon) of the black hole itself.
Is a hole 3 dimensional?
Black holes are 3 dimensional. They are simply celestial bodies like planets or stars but have so much mass that even light cannot escape their gravity if it is within a certain distance from them. In our universe of 3 spatial dimensions the event horizon is a 2-sphere.
Are black holes 4th dimension?
Yes, black holes are four-dimensional. Spacetime is four-dimensional (three dimensions of space and one dimension of time), and black holes are just a particular type of curved spacetime. No, black holes are not four-dimensional spheres.
Why can’t you see a black hole?
You can’t see them with the naked eye That’s because the gravitational pull at their centre is super strong. But with no reflection, we have nothing that can detect the hole directly. So instead, scientists look for the traditional effects a black hole has on its surroundings.
Why can’t we see the black hole in our galaxy?
Black holes swirling with stars But the majority of black holes in our galaxy are invisible, so the only way to find them is by observing their gravitational effects on surrounding objects. The outer star, known as a Be star, is several times more massive than the sun and burns hotter and bluer.
Will our Sun become a black hole?
However, the Sun will never turn into a black hole, because it is said to have less mass than needed to turn into one. When the Sun is about to reach its end and run out of its fuel, it will automatically throw off outer layers turning into a glowing gas ring known as a “planetary nebula”.
