Finally! A black Hole That You Can Visit And Survive!

Need a trip through a black hole without getting experience of irritating death? You're in luck. There's an unusual type of black hole that's not just only survivable, but might get you to alternative time, or maybe another universe. Black holes are, usually, the most terrifying things in the cosmos. Massive, mysterious, unavoidable, they wander through the cosmos and eat everything that gets too close. "Too close" is distinct by their event horizon. This is the point at which they go black, because it needs so much energy to escape them that not even light can get away. Since not even a photon can cross the barrier, no event that occurs inside the horizon can ever have an influence on people outside.

Except, something very odd was going on in the core of the black hole. Most black holes spin, this is something that was learned way back in the 1960s by physicist Roy Kerr. It wasn't precisely a shock, because most of the material that downfalls into a black hole was already spinning. Sometimes, nevertheless, the spin on Kerr black holes goes a little overhead and beyond. Ever spun a glass of water, or soda bottle, so that the liquid trapped inside swirls? If you spin it enough, the liquid in fact parts, leaving a clear center and a spinning circle of water around it. The same kind of thing can occur in Kerr black holes. As an alternative of a singularity at the center, there's a ring. And you can go over the open portion of that ring without touching the gravitational crush.

What's on the other side? A lot of people have speculated. Some people think that these type of black holes might be our key to effective time travel. They might be wormholes that permitt us hop between different points of the universe. Or they might be gateways to different universes completely. First we'll have to discover a few, and then we'll need a few volunteers to go over. Rather ones that haven't seen Event Horizon.
