Worm Holes, They're Real!

Everything in the universe exists in (at least) 4 dimensions: there are the three dimensions that we know of that make up space and the fourth is time. In complicated physics it becomes important to incorporate all four dimensions in calculations and it can be shown that space and time are not mutually exclusive entities. Instead they can be tied together and the four dimensions become known as space-time.

It can also be shown that space-time can be bent or even broken due to the force of gravity. Gravity has an effect on everything in the universe. Imagine you are traveling in a straight line between two points in space. Now imagine that there is a very large planet or star near your course of travel. Because of the objects gravitational impact, you must take a path that isn't a straight line but more curved in order to travel the shortest path. This is what I mean by bending space-time.

Einstein discovered that gravitational sources can also effect time. He theorized (and has since been proved right) that higher gravity fields cause time to slow down. So if you had a twin that lived out in space, he would age faster than yourself (but not by that much) and it is this principle that engineers must take into account when they work with satellites out in space.

It gets interesting when the concept of a black hole is introduced. A black hole is an object so massive that nothing can escape its gravitational pull. Not even light, hence the name black hole. If massive objects bend space-time, then a black hole would tear it. As you get closer to a black hole you may notice that time begins to slow down, and the closer you get the more time slows. At a certain point time would completely stop, but at that point you would face certain death and destruction.

It has been hypothesized that there could be objects which are the opposite of black holes. These objects would spit out anything that a black hole would suck in and would be known as a white hole. If white holes existed then each white hole would be connected to a black hole and a wormhole would be created.

Black holes are real objects and have been found in various places in the universe. To my knowledge no one has discovered a white hole. But it turns out that they are mathematically possible. To make matters better, wormholes are also mathematically possible. This probably explains why they are so heavily used in science-fiction works.

At the present moment, I would not recommend falling into a black hole to try and connect to another part of the universe. For starters the gravitational effects of a black hole would stretch your body so much that all three of your spatial dimensions would effectively collapse into one dimension (like a microscopic spaghetti). If you somehow survive the tidal forces from the black hole you may end up stranded in space with no hope of rescue. Finally, I won't be held liable for any injuries one may incur on such a trip.

If you do decide to try it though, have a buddy take a picture as you enter the wormhole and send me the postcard when you arrive on the other side.
