Time travel? Cooooooool!
Quiz question... what's a chrononaut?
Chrononaut - a time traveler
Ahh... that's it. And that what this page is about!
Spacetime... and how to time travel right now!!!
Spacetime, as mentioned in the '4th dimension' page, is a weird mixture of space and time. It shows the relation between space and time, and, by the way, has some whopper facts. This theory shows easy ways to travel through time. Anyway, you want to hear the first way to travel through time? Okay, it's... do nothing. I mean, here you are now, a few seconds/days/years/ages/centuries in the future, having read this crummy speech bubble because we wouldn't make a video, and this section of writing. Okay, time (Ha, ha, time is the theme of this subject. Oh, you don't get it? *Groan*) for the proper reasons how to travel through time!
1. Move
No, dude, seriously, if you move, time seems slower, and therefore you travel into the future. Cool, eh? If you stop looking at this piece of metal and go for the dreaded 'cross country run' you could travel to the age of jet-packs, couldn't you? No. If you walk 400 meters, then you only age 3 femtoseconds more than dudes who are slobbing out on the sofa. (That's 0.000000000000003 seconds!) *Yawn.* Lame! Next!
But wait! If you travel near the speed of light for 6 months, 6 months and a day would have passed! It doesn't seem much, but still..... it's alright.

2. Stand up
Come! Do it! Don't be shy! The less gravity their is, the faster time will pass, and, of course, the higher you are the weaker the pull, so standing up makes your head slightly younger then your feet. If you think this is some scientific uselessness that don't make any difference, you're wrong. Satellites move noticeably faster through time, being further away from earth, and have their clocks set back as a result.
3. Hope the universe is spinning
Errr... this should create 'time loops' via spacetime, helping you go forwards through time... then go back in time again through the loop to where you were before. Another way you could do this was by building a super-dense, spinning cylinder. Oh, and it has to be infinitely long. This should bend spacetime to create time loops.
What 'bout backwards?
Hmmm, yeeaaah, lets hook you up...
Albert Einstein's theory of relativity suggested that if you went faster then the speed of light, you might go backwards in time. Tut-tut, going past the speed of light is impossible. You see, people think that if time slows when you go at the speed of light, why shouldn't it go backwards if you go faster? Well, it's impossible, because you would use up a impossible amount of kinetic energy (i.e - movement energy) and when you go faster, your mass increases, thus making you use up even more energy!
(NB: The 'can't break the speed of light blah, blah ,blah' rule is only for things with mass, mind you. If you somehow moved your shadow across the moon from earth, boom, you'd have broken the speed of light.)

But don't despair! Other ways are here now!
People suspect 'wormholes' (a moving or spinning black hole is thought to create this difference, though some people say any old black hole will do.) are out there, so you can jump from one point in time to another. A way of imagining it simply as to think it as a plane with bit curved inwards, like a tunnel. In reality, the plane would be a sphere and the tunnel would be 4-D. On the other side would be another sphere, in a different point in time.
Other people believe that black holes are the same as wormholes, but, of course you'd be ripped apart before you had a chance get in there! Yet hope is still on the horizon! The completely theoretical Kerr Ring black hole states that a collapsed neutron star (i.e - a dead type of star that is less then 10km wide, but has strong gravity) has no singularity (i.e number 2 - a suction part of a black hole.) This means that you could travel through it safely. Yaaaaaaaaaaay!!!!!!!!
Of course, if you travel through it, you would launch out of a light hole, which emits the stolen light. Some people say you'd just go through another black hole, but this leads to a mystery - where does the sucked up light go to?
