00:03Black holes are one of our universe's greatest mysteries, with no one really understanding
00:08what happens once an object passes one of their event horizons.
00:12However, an astrophysicist at NASA's Goddard Space Flight Center has now built a supercomputer
00:16simulation revealing what it might theoretically be like to enter one of these cosmic vortices.
00:22Astrophysicist Jeremy Schnittman ran two simulations, the first of which shows what it would be like
00:27for an astronaut to graze an event horizon, but not pass through it.
00:30An event horizon is essentially the point of no return with regards to black holes, as
00:35anything which passes over one, even light, can never escape again.
00:38And that's one reason why black holes are so mysterious.
00:41We don't really know what happens on the other side.
00:43Even physics enters the territory of paradox when attempting to define the inner workings
00:47of black holes.
00:48Still, a second computer simulation attempts to show, as best we can guess, what plunging
00:53into a black hole might be like.
00:54The simulation begins relatively similarly to the first, until it ends in utter blackness.
00:59No doubt a by-product of physics breaking down around you, Schnittman says that on a consumer-grade
01:04computer, the calculations used to produce these visualizations would have taken some 10 years
01:09Larry Hig�� Rose Lira replaced the oraz black holes.
