At the edge of a black hole, or the event horizon, time begins to slow astronomically. The farther into a black hole you venture, the more distorted time becomes.So, while general relativity is agnostic about the reality of white holes, thermodynamics gives the concept a hard no. The only way to form a white hole would be to have some exotic process operating in the early universe that baked the existence of a white hole into the fabric of space-time itself.“If you were to stand just outside the event horizon of Sagittarius A*, and you stood there for one minute, 700 years would pass because time passes so much slower in the gravitational field there than it does on Earth.” Some have suggested that black holes could be used for time travel.
How do white holes violate the second law of thermodynamics : Answer and Explanation:
The White hole tends to decrease the entropy of the universe while the second law of thermodynamics explains that the net entropy of the in the universe can either increases or remain constant; it should not be decreased. The second law and property of white hole contradict each other.
Is time infinite in a black hole
These tidal forces run to infinity in finite time, marking the abrupt end of an entire region of spacetime at the so-called black hole singularity—the place where time stops and space ceases to make sense.
Can a black hole cause time travel : If a person were to hang out near the edge of a black hole, where gravity is prodigious, Goldberg says, only a few hours might pass for them while 1,000 years went by for someone on Earth. If the person who was near the black hole returned to this planet, they would have effectively traveled to the future.
A Q-star, also known as a grey hole, is a hypothetical type of a compact, heavy neutron star with an exotic state of matter. Such a star can be smaller than the progenitor star's Schwarzschild radius and have a gravitational pull so strong that some light, but not all photons, can escape. With a white hole, you have an event horizon, where stuff from the inside crosses the event horizon and gets ejected into the universe, and you can't actually get into the white hole. So in the black hole, you can pass inwards, but not outwards in a white hole, you can pass outwards but not inwards.
How long is 1 year in a black hole
A clock near a black hole will tick very slowly compared to one on Earth. One year near a black hole could mean 80 years on Earth, as you may have seen illustrated in the movie Interstellar. In this way, black holes can be used to travel to the future.Although the ordinary second law will fail when matter is dropped into a black hole, such a process will tend to increase the area of the black hole, so there is a possibility that the GSL will hold.A white hole is a time-reversed black hole – a region of spacetime where matter spontaneously appears and explodes outwards, rather than implodes and disappears as with a black hole. White holes are the opposite of black holes, in that they spit out light and matter, rather than trapping it. You can't escape from the black hole for the same reason you can't escape from the future. Time doesn't stop at the event horizon. If you fall into a black hole, time continues as normal for you as you pass the event horizon.
Would 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. For example, an object falling into the hole would appear frozen in time at the edge of the hole. Inside a black hole is where the real mystery lies.
Is time travel possible in 3000 : Conceptually, it is possible to do something similar with humans. To visit the Earth in the year 3000, it is necessary only to hop in a spaceship that can travel at 99.995% of the speed of light.
Would time be infinite in a black hole
These tidal forces run to infinity in finite time, marking the abrupt end of an entire region of spacetime at the so-called black hole singularity—the place where time stops and space ceases to make sense. At first we thought that these things were normal blue black holes hidden behind clouds of interstellar dust, that absorbed the blue light and made them appear pink. It turns out that this is only true for a few of them: most have the wrong colours to be expained by this.Scientists like Roger Penrose theorize that a white hole is like an exit for a black hole in another universe. So material would fall into a black hole in one universe and would get ejected into another universe via a white hole.
Is a white hole a dying black hole : Shockwave cosmology, proposed by Joel Smoller and Blake Temple in 2003, has the “big bang” as an explosion inside a black hole, producing the expanding volume of space and matter that includes the observable universe. This black hole eventually becomes a white hole as the matter density reduces with the expansion.

Antwort When we find evidence that black holes transform into white holes it would mean that spacetime can also make quantum jumps? Weitere Antworten – How do black holes affect spacetime
