Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. … According to Einstein's theory, time and space, in a way, trade places inside the hole. Inside the black hole,
the flow of time itself draws falling objects into the center of the black hole
.
Does time go backwards in a black hole?
Your intuition is misguided,
time does not run backwards inside a black hole
. For an observer inside a black hole, time passes in a perfectly “normal” way, such as it does at the horizon. The stopping of time of time at the horizon is, as you mentioned, a phenomenon that only an outside observer experiences.
Is there anything inside a black hole?
In that sense,
black holes lead nowhere because nothing could ever get inside
. This, however, violates Einstein's general theory of relativity.
What happens if you go inside a black hole?
The event horizon of a black hole is
the point of no return
. Anything that passes this point will be swallowed by the black hole and forever vanish from our known universe. At the event horizon, the black hole's gravity is so powerful that no amount of mechanical force can overcome or counteract it.
Does time exist inside 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
.
What happens if a black hole swallows Earth?
Will Earth be swallowed by a black hole?
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.
Can you go thru a black hole?
Scientists say humans could indeed enter a black hole to study it. … Of course, the human in question couldn't report their findings—or ever come back. The reason is that supermassive black holes are much more hospitable.
Can a wormhole exist?
Wormholes are consistent with the general theory of relativity, but
whether wormholes actually exist remains to be seen
. … Theoretically, a wormhole might connect extremely long distances such as a billion light years, or short distances such as a few meters, or different points in time, or even different universes.
What is beyond the event horizon of a black hole?
There is simply a region, or boundary, in space around a black hole beyond which
we cannot see
. This boundary is called the event horizon. … Anything that passes beyond the event horizon is doomed to be crushed as it descends ever deeper into the gravitational well of the black hole.
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 is the scariest thing in the universe?
Supermassive black holes
are strange
The biggest black hole discovered so far weighs in at 40 billion times the mass of the Sun, or 20 times the size of the solar system. Whereas the outer planets in our solar system orbit once in 250 years, this much more massive object spins once every three months.
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”.
Can a black hole swallow a galaxy?
A single Black Hole, even one at the center of our Milky Way galaxy,
is just too small to eat an entire galaxy
.
How far from a black hole is safe?
For a normal-sized black hole,
between fifty and seventy miles
is a safe distance to orbit. A black hole is a sphere in the sense that everything that goes within its Schwarzschild radius (the distance from the center of the black hole to the event horizon) cannot escape its gravity.
Is travel back in time possible?
While the debate continues over whether travelling into the past is possible, physicists have determined that travelling to the future most certainly is. And you don't need a wormhole or a DeLorean to do it. Real-life time travel occurs through
time dilation
, a property of Einstein's special relativity.
Has anyone been through a wormhole?
Wormholes are sci-fi staples; over the years, many stories, books and movies have sent their protagonists zipping between widely separated locales via these cosmic shortcuts. Wormholes are possible, according to Einstein's general theory of relativity, but
nobody has ever spotted one
.
