Time Travel

[Artificial]

i was watching science channel.. they were designing this space ship that travels so fast that when you leave earth and go into space. your traveling so fast that what feels like 5 years in space is like 10 years on earth. so it's sorta like time travel. to the future.?

That is correct, according to Einstein's theory of special relativity. Time is relative, and put simply, as you approach the speed of light time dilates. Astronauts in orbit around the earth experience this effect. Sergei Krikalev has logged the most time in space, and I do believe he therefore also holds the record for being the greatest time traveler.

About 800 days he was in orbit going 17,000 miles an hour. So, he is right now a one forty-eighth of a second younger then he would have been if he had stayed home. So, that means that when he came back to the earth, he found that one forty-eighth of a second to the future of where he expected it to be. So this man has actually time traveled one forty-eighth of a second to the future.

this is true, but considering how vast the vessal would need to be, there would be no amount of fuel large or powerful enough to fuel it. and as i recall size is relative to speed.

and moving at the speed of light would cause so much strain on the vehicle the vessal would be obliterated before it could reach lightspeed.

This is pretty amazing even if it's such a small ammount of time.. think of what will be in 20 years!

They were designing a ship that was "solar powered" using the radiation and uv found in space. and the hydrogen molecules... seeming how there is so much because it's a star's main fuel source.
