The birth of our universe may have come from
a black hole
. Most experts agree that the universe started as an infinitely hot and dense point called a singularity. … It is, in fact, and some physicists say they could be one and the same: The singularity in every black hole might give birth to a baby universe.
What is inside a Blackhole?
A black hole is a tremendous amount of matter crammed into a very small — in fact,
zero — amount of space
. The result is a powerful gravitational pull, from which not even light can escape — and, therefore, we have no information or insight as to what life is like inside.
Is there life inside a black hole?
So planets could potentially form around black holes, but that's
no guarantee
that they offer a life-friendly environment. … Without the glow of a star, life around a black hole would likely need an alternative source of energy. Fortunately, that might not be too hard to come by.
Will a black hole come to earth?
Scientists have discovered one of the smallest black holes on record – and the closest one
to Earth
found to date. … Very few black holes of this mass have been found in the universe. This black hole is 1,500 light years away from Earth, still inside the Milky Way galaxy.
Do black holes create universes?
In other words, the study suggests black holes might actually burrow into a kind of multidimensional object called a brane, and
give birth to an entirely new universe
in another colossally big bang.
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.
Can a black hole eat a planet?
Can a Black Hole Destroy Earth? Many believe black holes go around in space eating stars, moons and planets. Scientists have debunked this perception. Earth is
facing no threat
because no black hole is close enough to the solar system for our planet.
What if we fell into a black hole?
If you jumped into the black hole feet first,
the gravitational force on your toes would be much stronger than that pulling on your head
. Each bit of your body would also be elongated in a slightly different direction. You would literally end up looking like a piece of spaghetti.
What happens to things inside a black hole?
When matter falls into or comes closer than the event horizon of a black hole, it becomes isolated from the rest of space-time. It can never leave that region. … Once inside the black hole's event horizon,
matter will be torn apart into its smallest subatomic components and eventually be squeezed into the singularity
.
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”.
How long does a black hole last?
For example, a black hole of 1 solar mass takes 10
67
years to evaporate (much longer than the current age of the Universe), while a black hole of only 10
11
kg will evaporate
within 3 billion years
.
Where is the nearest black hole?
For a comparison,
Sagittarius A
, the supermassive black hole at the center of the Milky Way, is thought to be about 4 million times the mass of the sun. In addition to being among the smallest black holes ever seen, it's the nearest one to us that we know of, at just 1,500 light years away.
Can a black hole destroy a galaxy?
Black holes are
the most powerful destructive forces in the universe
. They can rip apart a star and scatter its ashes out of the galaxy at nearly the speed of light. But these engines of destruction can also pave the way for new stars to form, as a new study in Nature shows.
Can time be stopped?
The simple answer is, “
Yes, it is possible to stop time
. All you need to do is travel at light speed.” The practice is, admittedly, a bit more difficult. Addressing this issue requires a more thorough exposition on Special Relativity, the first of Einstein's two Relativity Theories.
Why does time slow down at a black hole?
An object approaching the event horizon would appear to be slowing down as it approaches the black hole instead of speeding up as we would expect. This is because of
time dilation
, which slows the passing of time for an object moving close to the speed of light with respect to an outside observer.
