Black holes form natural time machines that allow travel to both the past and the future. But don't expect to be heading back to visit the dinosaurs any time soon. At present, we don't have spacecraft that could get us anywhere near a black hole.Theoretical physicists suggest that black holes may be the gateway to distant parts of our universe or even other universes. It has even been suggested that there may be a theoretical white hole on the other side of the black hole in a parallel universe, which, on the contrary, actively ejects matter around 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.
Are we inside a black hole : No we are not. In a non-rotating black hole, all worldlines lead to the central singularity. You cannot move outward, and all light comes to you from the outside, not the center. We can move around in all directions see arriving from all directions, so we are not in a non-rotating black hole.
Could you survive a black hole
It depends. A stellar-mass black hole would quickly tear you apart. But a person encountering a supermassive black hole could survive for hours.
Can black holes take you to another dimension : This however is only the case for black holes that are static. That are not rotating. And do not have any electric charge the the simplest.
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. 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. According to Einstein's theory, time and space, in a way, trade places inside the hole.
Will Earth enter a black hole
Despite their abundance, there is no reason to panic: black holes will not devour Earth nor the Universe. It is incredibly unlikely Earth would fall into a black hole because, at a distance, their gravitational pull is no more compelling than a star of the same mass.White holes are the opposite of black holes, in that they spit out light and matter, rather than trapping it. So far, white holes are purely hypothetical objects, but astronomers are contemplating how they could form in reality.The fate of anyone falling into a black hole would be a painful “spaghettification,” an idea popularized by Stephen Hawking in his book “A Brief History of Time.” In spaghettification, the intense gravity of the black hole would pull you apart, separating your bones, muscles, sinews and even molecules. So planets could potentially form around black holes, but that's no guarantee that they offer a life-friendly environment. On Earth, living things are hugely dependent on the light and warmth from the Sun to survive. Without the glow of a star, life around a black hole would likely need an alternative source of energy.
Could a human survive a black hole : Within any black hole is the central point, the singularity, which has infinite gravity and where mass is compressed into an infinitely small point. There, it is game over. There's no surviving. And therefore the idea of traveling through time and space, via black hole or wormhole, don't really register in reality.
What is 1 hour in black holes : According to some theories, an hour inside a black hole would be equivalent to a billion years for someone outside it. This is because time and space would be distorted by gravity so much that they would not exist as we know them.

Do grey holes exist : 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.
