Thanks to a NASA supercomputer, immersive visualization allows us to explore what happens when we approach a black hole.
Jeremy Schnittman, an astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, created these visualizations to simulate two scenarios: in the first, the camera grazes theevent horizon and is ejected, while in the second, she traverse and seals his fate.
Better to choose a supermassive black hole, says Schnittman. Unlike stellar black holes, which have a horizon smaller events and forces of tide stronger ones that can tear objects apart before they even reach the horizon, a black hole supermassive stretches approaching objects less strongly.

As the camera approaches the black hole, reaching speeds close to the speed of light, the glow of the disk d’accretion and stars in the background intensify. The images become more and more distorted, formant even multiple images as their light passes through thespace-time more and more distorted.
In real time, it would take the camera about 3 hours to reach the event horizon. However, to a distant observer, the camera image would appear to slow down and then freeze just before the horizon, due to space-time distortion.
This visualization of a path to a supermassive black hole shows the strange effects of Einstein’s general relativity. The camera approaches, briefly orbits, then crosses the event horizon, the point of no return of a gigantic black hole similar to the one at the center of our galaxy.

Crossing the event horizon, spacetime itself flows inward at the speed of light. Past this point, everything is sucked toward the center of the black hole, a point called singularitywhere physical laws as we know them cease to apply.
