Jeremy Schnittman, an astrophysicist at NASA’s Goddard Space Flight Center, said that’s a question people ask scientists very often, according to ScienceAlert.
“Simulating these hard-to-imagine processes helps me connect the mathematics of relativity to real-world consequences in the real Universe.” So I modeled two different scenarios: one where the camera, a surrogate for the brave astronaut, simply passes the event horizon and flies back, and another where it crosses the boundary, thus cementing its fate,” he said.
The event horizon is the boundary around the black abyss, from which light rays, let alone other particles or objects, cannot escape.
You can see the simulations in the following videos:
Black holes, or black abysses, are formed from the massive cores of dead stars that collapse under the influence of their own gravity, they are so dense that their material is compressed into a space that is difficult for today’s physics to understand, according to ScienceAlert.
However, one of the effects of this compression is the formation of the event horizon, the boundary where the pull of gravity is so strong that even the speed of light is not enough to escape it. This means that we cannot know what is beyond the event horizon.
Light is the main tool we use to study the Universe. If we can’t see any light from inside a black hole, we simply can’t tell what’s there, reports ScienceAlert
Theoretically, one can encounter paradoxes when information remains in the event horizon from the observer’s point of view, but is hidden forever from the point of view of the object crossing the boundary.
J. Schnittman, who prepared several simulations of black holes at NASA, based his new simulation on a supermassive black hole, very similar to Sagittarius A* (Sagittarius A*). It started with a black hole with a mass of about 4.3 million. suns, and together with data scientist Brian Powell, who also worked at Goddard, fed the data into NASA’s Discover supercomputer.
