00:00 Black holes are one of our universe's greatest mysteries, with no one really understanding
00:08 what happens once an object passes one of their event horizons.
00:11 However, an astrophysicist at NASA's Goddard Space Flight Center has now built a supercomputer
00:16 simulation revealing what it might theoretically be like to enter one of these cosmic vortices.
00:23 Astrophysicist Jeremy Schnittman ran two simulations, the first of which shows what it would be
00:27 like for an astronaut to graze an event horizon, but not pass through it.
00:30 An event horizon is essentially the point of no return with regards to black holes,
00:35 as anything which passes over one, even light, can never escape again.
00:38 And that's one reason why black holes are so mysterious.
00:41 We don't really know what happens on the other side.
00:43 Even physics enters the territory of paradox when attempting to define the inner workings
00:47 of black holes.
00:48 Still, a second computer simulation attempts to show, as best we can guess, what plunging
00:52 into a black hole might be like.
00:54 The simulation begins relatively similarly to the first, until it ends in utter blackness.
00:59 No doubt a byproduct of physics breaking down around you, Schnittman says that on a consumer
01:03 grade computer, the calculations used to produce these visualizations would have taken some
01:08 ten years to complete.
