I tend to remember a lot of what I read. Especially if its a topic I'm fascinated by, such as astrophysics.

Time travel, for example, is theoretically possible. Forward, at least. Backwards...I believe not due to the wormhole would collapse on itself.

In order to travel forward in time, you need to attempt to go the speed of light. Now, as weird as this sounds, the universe does not like that. So time would slow down around you. Basically, more or less, you would travel near the speed of light for a full day, and roughly 100 years around you would pass.

I think. My math COULD be wrong...

It takes light approximately 6 hours to reach the start formerly known as a planet, Pluto. It would take us approximately 24 years. So roughly 100 years would pass in a day of traveling at light speed.

Neat. I need to do this.
