What will you see when you are in a black hole?
A black hole is a space-time region of extreme gravity. The surface of a black hole is called the event horizon. It divides the universe into two parts, inside and outside.
Black holes are forged from the small, dense, remnant cores of dead stars. If the core's mass is more than about three times the mass of the Sun, the force of gravity overwhelms all the other forces, and the remnant collapses and produces a black hole.
Black holes are objects with extreme density, and the amount of mass they have means they have so much gravitational pull that even light gets trapped. Astronomers believe that most spiral and elliptical galaxies have black holes at their centers.
A simulation in the video shows us what an astronaut would see as they fall towards a black hole. This involves phenomena such as the doppler effect, gravitational lensing, relativistic aberration, gravitational redshift/blueshift, and the equivalence principle.
It also corrects the often repeated misconception that the astronaut would "see the whole future of the universe" as they fell in, which would only happen if they hovered just outside the event horizon. If they cross the horizon, their time is limited and they won't see much of the future as there is not enough time for the light to reach them before they reach the singularity.
Phase I Before the fall
Before we even start falling we run into a problem the black hole is supermassive its grativity equates to mass millions of times greater than the sun with such an attraction it capture stars and surrounding mata forming a thick disk of plasma that orbits around it. We will therefore assume that we are equipped with an extremely resistant spacesuit which allows us to withstand the heat and filter out any harmful radiation.
However despite the spacesuit the disc still seems extremely bright we can’t distinguish anything. We will imagine that our helmet has a visor which helps reduce the brightness of the disc so that we can observe it in detail as well as see the stars in the background.

Phase II Falling through the disc
During the first 10 minutes of the fall, the black hole seems to be moving away. We are moving closer and closer to it, but its image seems to shrink more and more.
Phase III Crossing the horizon
Just two minutes later we are twice as close to the horizon from now on any light coming from the outside is destined to fall into the black hole. This is called a photon sphere.Our image will slow down and fade until freezing on the horizon of light we emit takes more and more time to escape from the receptive black hole which is getting slower and slower.
