NASA experts from the Robert H. Goddard Space Flight Center, with the help of the Discover supercomputer, created a visualization of a supermassive black hole with a mass about 4.3 million times greater than the Sun, resembling the Sagittarius A* object, which is located in the center of the Milky Way.
NASA showed a simulation involving a supermassive black hole
– I simulated two different scenarios. One in which the camera, standing in for the daring astronaut, simply passes the event horizon and launches itself on a slingshot, and the other in which he crosses the boundary, sealing his fate, said astrophysicist Jeremy Schnittman, .
The first simulation shows a moment that resembles an approach to a supermassive black hole. At the beginning of this visualization, the camera is approximately 640 million km away from the object. – When the camera crosses the horizon, it only takes 12.8 seconds to destroy it due to spaghettification – explained Schnittman. From this point on, the distance to the singularity is 128,000. kilometers, and the last stage of this space journey ends in the blink of an eye – describes the NASA agency.
The second simulation, however, shows the camera approaching a supermassive black hole, but it does not cross the event horizon and ultimately “escapes” from the object. “If an astronaut flew on a spacecraft for a 6-hour round trip and her colleagues stayed on the spacecraft far from the black hole, she would return 36 minutes younger than her colleagues. This happens because time moves slower near a strong source of gravity and when it moves at a speed close to the speed of light,” explains the US space agency.
The so-called Spaghettization in astrophysics means the phenomenon of vertical stretching and horizontal compression of a celestial body into an elongated shape (hence the association with spaghetti). Cosmic stretching occurs under the influence of a powerful and compact gravitational field. In extreme cases, the stretching and compression near a black hole is so powerful that no object in space can resist this force.
The supercomputer created the simulation in 5 days. A typical laptop took over a decade to complete
The Discover supercomputer is located at NASA’s Climate Simulation Center. The above visualization took five days to create. 0.3% was used to prepare it. chipsets from 129 thousand supercomputer processors. “On a typical laptop, the same feat would take over a decade,” the agency says.
