If its true, so what. He set us back a few many decades. We still wouldn't be able to travel at the speed of light anyways. |
This wasn't a calculation, they had these particles already do this. They weren't trying to go faster than the speed of light but it happened anyway.
This is no dig on Einstein, the man was a genius, but he was only working with the information he knew at the time. As mankind progresses, we will continue to understand more about the universe and I find that exciting! We are barely infants in the grand scheme of things... |

From what I understand, if you get close enough to the event horizon of a super-massive black hole, then time will slow down for you (due to it's gravitational effects on space/time), but not for anyone else. This really isn't time travel, as I like to call it "time trickery".
Personally I'm on the side of real time travel being impossible. |

Thanks for sharing this! I think a lot of the geeks on here will find this interesting. |
I'll have to agree. Terrific implications for science. I believe we are at a key junction in the understanding of this universe and its inner workings. The next 5 to 10 years should be quite interesting to keep an eye on. |

I think a lot of ground breaking research will be done in the next 5-10 years, but we won't see any implications in application for 20-30 years. It just takes so long for us to go from lab to factory; that time frame gets longer the more theoretical the science is.
I remember reading about paper thin batteries for portable devices in the late 90's. It took about 10 years for those batteries to show up in consumer electronics. |

Actually, time slows down then stops inside a black hole and that wouldn't bring you forward in time unless you were able to escape (although this may have been you're point). Although nobody knows what happens after you're in.
Most people agree that going back is impossible, but that going forward is possible with the right conditions. Stephen Hawking suggested a couple ways in a TV series about time travel which was fascinating. One of those ways was if we could build some sort of train or something that could circle the earth at the speed of light, and because the laws of the Universe won't allow anything to travel past the speed of light (or though we thought), if you were on that train walked from the back to the front you would essentially be traveling faster than the train (or faster than the speed of light). So since this was impossible, time would actually be slowed down on the train as you reach the speed of light, which meant that after a week on the train you would walk out and 100 years would have past on earth. I thought that was pretty amazing stuff, but we may have to rethink that now with this new discovery.
Now I know we can't build such a train (yet) but it is still pretty awesome stuff. |

| All you're doing is describing a form suspended animation since time for you is almost frozen whilst time to everyone else continues normally. Like I said on my prior post... "time trickery". It's not like your actually traveling though time. You're just immensely slowed down. |

I understand what you're saying, but this is what our scientific community thinks is possible when discussing "time travel".
To be honest, ANY form of time travel....whether it's getting into a phone booth and walking out 20 years before or after.....could still be called "time trickery". That's how mankind would have to do it, learn how to manipulate the rules around time.
If we walked out of the train I mentioned earlier a 100 years in the future, I would call it time travel because we would have traveled 100 years into the future (or time). We would have "traveled" in "time". |

| What your describing is no different than just freezing yourself for a hundred years and waking up. |

any of you guys ever read Einstein's original paper that publicized the special theory of relativity (aka e=mc2)?
the weird part of that theory was that it was based on a fiction, on an untested hypothetical situation.
it goes like this:
if an observer standing on Planet A fires a laser to an observer holding a mirror on Planet B, then when the laser reflects and travels back towards Planet A the time that it took to go from B to A will be equal to the time it took to get from A to B.
and that's it.
weird thing about science is compression. a guy's life work is jammed into a few equations. no-one bothers to read the original writings that lay out the premises for the conclusions. |

What? Freezing yourself for a hundred years is a HUNDRED years! You getting on this train for a week is a WEEK of your life, yet a hundred years have passed just outside the door. Your are NOT frozen or in suspended animation!
It's just like that Time Machine movie, where he pushes the level and sees the world age outside for thousands of years. |
