A black hole is
an area of such immense gravity that nothing—not even light—can escape from it
. Black holes form at the end of some stars' lives. The energy that held the star together disappears and it collapses in on itself producing a magnificent explosion.
What happens if a person goes into a black hole?
Thus, the person would pass through the event horizon unaffected, not be stretched into a long, thin noodle, survive and float painlessly past the black hole's horizon. A person falling into a supermassive black hole
would likely survive
.
What's inside a black hole?
HOST PADI BOYD: While they may seem like a hole in the sky because they don't produce light, a black hole is not empty, It's actually
a lot of matter condensed into a single point
. This point is known as a singularity.
What is the purpose of a black hole?
A black hole is an astronomical object with
a gravitational pull so strong that nothing, not even light, can escape it
. A black hole's “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos.
How a black hole is formed?
Stellar black holes form
when the center of a very massive star collapses in upon itself
. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space. Scientists think supermassive black holes formed at the same time as the galaxy they are in.
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
.
Does time stop in a black hole?
Near a black hole, the slowing of time is extreme. From
the viewpoint of an observer outside the black hole, time stops
. … Inside the black hole, the flow of time itself draws falling objects into the center of the black hole. No force in the universe can stop this fall, any more than we can stop the flow of time.
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.
Will a black hole come to earth?
Absolutely not
. While a black hole does have an immense gravitational field, they are only “dangerous” if you get very close to them. … It would get very dark of course and very cold, but the black hole's gravity at our distance from it would not be a concern. Is there life on other planets?
What's 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. … The research began with a slightly different aim of a more common light formed by a black hole: the corona which wraps around the outside of it, formed as material falls in.
What is the disadvantage of black hole?
They break down exactly where they are expected to break down: when space-time curvature becomes very large. The disadvantage is that some have
argued it leads to another paradox
, that of the possibility to infinitely produce black hole pairs in a weak background field: i.e., all around us.
What are the 4 types of black holes?
And anything that ventures too close—be it star, planet, or spacecraft—will be stretched and compressed like putty in a theoretical process aptly known as spaghettification. There are four types of black holes:
stellar, intermediate, supermassive, and miniature
.
What did Einstein say about the black hole?
Over a century ago, Albert Einstein predicted that
the gravitational pull of black holes were so strong that they should bend light right around them
. Black holes don't emit light, they trap it; and ordinarily, you can't see anything behind a black hole.
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”.
Who found the first picture of a black hole?
A 29-year-old computer scientist has earned plaudits worldwide for helping develop the algorithm that created the first-ever image of a black hole. Katie Bouman led development of a computer program that made the breakthrough image possible.
Do all galaxies have black holes?
Most galaxies of comparable sizes that
are active have much larger black holes
. Andromeda, which is at most about twice the mass of the Milky Way, has a black hole that's more like ~80-100 million solar masses. Many other galaxies have black holes reaching into the billions or even tens of billions of solar masses.
