Yes. he is the one who discussed the possibility of time travel. |

No. |

I understand the question, but this is not a question for me. I don't believe time travel will happen though; if it will, people should already have come back and said 'Check it out!' |

you spelled "what" wrong  |

If I remember correctly, given Einstein's theories, time travel would mean traveling faster than the speed of light -- which, I think he said was not possible. There's some tricky business about becoming infinitely massive or something like that.
Einstein did theorize that time would pass at different rates for different frames on reference, though. I think one of his examples was two twins. One twin stays home on Earth while the other gets in a space ship and travels at 2/3rds the speed of light for a year or so, then comes back to Earth. When he gets back, his twin has aged 20 years (while he only aged 1 year). I'm just making up these numbers, but was something like that. I think this effect has been proven by experiment as well (using atomic clocks and fast-moving airplanes). It's not exactly time travel, though. |

Is time based on the speed of light?
I always equated our notion of time with the moon revolving around the earth, the earth around the sun.
So I guess my answer is, "Dunno". |

I think anything other than light approaching the speed of light is as likely as reaching absolute zero - maybe we could almost get there, but not quite. |

I don't know. I don't know enough about relativity or whatever other theories are relevant to the discussion. |

I don't know Einsteins theory so I can't say for sure. But I will agree that with quantum physics anything is possible |

No, why would going faster than light make you go back in time. Wouldn't you just get there faster. Also, time is based on the speed of light? wtf?
btw-- going faster than light is not really possible. That because the energy to accelerate something to that speed approaches infinity. |

As far as I know, Time Travel is not possible. |
| JessicaWoman99 | | posted 17-Jan-2008 11:07pm |
No time travel is not possible at all Einstein is very wrong in his thinking |
| Irene007 | | posted 18-Jan-2008 3:46am |
Only according to him... I haven't seen anyone do it as of yet

Doubtful. |

I ticked all the options, but it's a scientfic and philsophical question in my mind. |

What is it?

You have no idea what you are talking about, do you?
I didn't think so... |
| RGirl | | posted 25-Jan-2008 6:09pm |
Yes, I do. We won't ever accomplish it but I believe it is. |
| kcthedog | | posted 19-Feb-2008 8:32pm |
It would be pretty presumptuous on my part to attempt to second guess Einstein, while I am familure with the whole relativity concept I have to accept it with a bit of a grain of salt. The theory has been tested with spacecraft and atomic clocks and has been verified but hardly opens the possibility for humans to transcend time and space. The difference between particle theory and space/time travel is pretty extreme. |
