is it possible? I personally don't think it is, and if it is it's going to take a very long time until we figure out how. |

In theory, time travel would be possible if one were to travel at light speed, or faster than light speed. But this is also impossible, in theory. We may one day figure something out, but as of now, and for the next century probably, it's impossible. |

Completely, in fact this guy has done it already! http://timetraveler.ytmnd.com/ Ah yes, did I mention there is heavy sarcasm within this? |

I thought it was on an extremely unoticeable level. I heard of an experiment where they took two sycronized clocks, put one on a Concord jet and another on the ground, then launched the jet across the ocean, when it landed, the clock on the jet was slightly ahead of the other. Must have had a flux capacitor. |

Wouldn't the clock on the jet be behind the ground clock? |

Yeah the concord clock would be a little behind, but in order for it to be noticeble, it would have to be in the plane for a really long time. |

I've never been one to believe that going faster than the speed of light results in moving backwards in time. Granted I've not the physical sciences background required to have much of an opinion on the matter, it just doesn't seem logical. That, and going the speed of time kills you. |

Well a simple way to kind of explain it would be to think of it this way, we use our energy to travel through 4 dimensions, 3 spatial and 1 time. As we move faster through the 3 spatial dimensions, we use more energy on those, thus using less energy on the time dimension, which means we would travel through it more slowly, making time move slower for us. Since light speed is the limit one can move through the 3 spatial dimensions, if we were to go that speed, we would no longer have energy to move through the time dimension, thus stopping time. Photons, for example, are always moving at light speed, therefore they never age, they are the same age now as they were when the universe was created. So instead of really going back in time, I guess you would travel forward in time, but this is all theory obviously. |

An interesting way (and accurate) to think about it is that you get arbitrarily close to the speed of light you grow increasingly heavy. And, as you know, the heavier you are the more energy it requires to move. As such, your body would be getting heavier and heavier and it would require more and more energy. As such it takes and infinet amount of energy to get to the speed of light. The clocks were atomic clocks, as such they could detect a millionith of a second difference. |

How do you get heavier? I hear when you approch the speed of light you get really skinny too. I like that explanition #1. I just don't know how you get heavier. (I'm not doubting you; I'm just curious) |

Well it is only skinner looking to those not in motion watching the object, it will appear that it has a smaller width to them. To the person traveling at the speed, they seem the same width to themselves. The reason they get skinnier is because since time slows down, it takes a less amount of time for the entire object to cross a line for example, which means that the length of the object would be shorter in the direction of motion. The reason you get heavier is because of E=mc^2. As you approach the speed of light, your energy increases. Since c is constant, this means your mass would increase too. As you move faster and faster, you become heavier and heavier, making it so the force needed to keep you going would need to be increased as well, eventually, your mass would become infinite, which is, of course, impossible. |

Ah, that is why you can't go faster than the speed of light. I always knew a little bit of it and never got the whole explanation. Thanks a lot miller. |

Oh, yeah, sorry. You all are right, concepts the same, though. |
