A black hole with a view

Physicists have calculated what the universe would look like from inside a black hole, and not just for fun

Ever wondered what it's like to fall into a black hole? Wonder no more! Andrew Hamilton at JILA at the University of Colorado and a pal, Gavin Polhemus, have created a video showing what it might look like

Inside Black Holes

What really happens inside black holes? Are there wormholes inside black holes? Do black holes give birth to baby universes? These questions lie at the frontier of research into relativity. The aim of this website is to take you to the frontier, and maybe even a bit beyond it.

This is a general relativistic visualization of a supercomputed magneto-hydrodynamic simulation of a disk and jet around a black hole. The disk and jet were supercomputed by John Hawley at the University of Virginia. The general relativistic rendering was done with the Black Hole Flight Simulator.

In general relativity, a black hole is a region of space in which the gravitational field is so powerful that nothing, including light, can escape its pull. The black hole has a one-way surface, called the event horizon, into which objects can fall, but never emerge from. It is called "black" because it absorbs all the light that hits it, reflecting nothing, just like a perfect blackbody in thermodynamics. Quantum analysis of black holes shows them to possess a temperature and radiate like black bodies.

Despite its invisible interior, a black hole can reveal its presence through interaction with other matter. A black hole can be inferred by tracking the movement of a group of stars that orbit a region in space which looks empty. Alternatively, one can see gas falling into a relatively small black hole, from a companion star. This gas spirals inward, heating up to very high temperature and emitting large amounts of radiation that can be detected from earthbound and earth-orbiting telescopes. Such observations have resulted in the general scientific consensus that, barring a breakdown in our understanding of nature, black holes do exist in our universe.[2]
