Not my opinion, in fact I don't have one because time travel is so far beyond what my poor brain can handle but some scientists are now saying time travel is not possible. Hit the jump to find out why.
Most of us are familiar with the concept of light speed which is how fast light can travel. According to Einstein that's as fast as anything can go. Somehow break that speed and you're moving thru time but there's a fatal flaw to this theory.
Time is a human invention. It is our way of measuring what time really is - the state of all particles in the universe at any given moment. It really doesn't have anything to do with moving faster than the speed of light. No, all that does is alter our perception of time when in reality the particles in the universe are still changing.
This would suggest that in order to time travel, a machine would have to record the state of every particle in the universe. Then you have to figure out how to change every single particle back to the state of your intended "time". This also suggests our trips are limited to when the machine first started recording. On top of that, it wouldn't be possible to travel into the future since there's no data recorded yet. The future is where all particles have infinite possibilities of change.
It's an interesting theory except I think I read somewhere how our perception of time is incorrect, that in fact time is not linear. That's hard to imagine since we are corporeal beings and everything we do is at least based on a past and present.
I must go now. My head hurts.
finally! humans can no longer alter the time-space continumm anymore!
still nice to fantasize about...
also theres not just that though maybe try looking at tenthdimension.info for a theory of time travel.
What!? how does the theory of relativity tie into all of this?
Though I agree with these Scientist; history shows us that Scientist are wrong infinitely more times than they are right, it's the nature of the subject.
Who knows really? Interesting post. Thank you very much for that interesting and insightful post.
Soooooooo, this time travel machine would basically be giant Tivo? ;D

Yes basically. LOL
1. The guy who wrote that article isn't a "scientist" any more than you or I.
2. He really didn't address any hardcore scientific data, and his views on the nature of time are more philosophy than anything else.
3. We travel into the future all the time... Time dialation at near light speeds WOULD allow someone to progress into a future that would normally be meyond their natural lifespan. See: that story about the twin brothers and the rocket ship, etc.
4. This article doesn't definitively disprove time travel as a whole, it just proves that the two techniques discussed are not acceptable. (It would be like saying "Well, these two aeroplane designes didn't work, I guess powered flight is impossible for man. Forever.)"
/rant.
There will never be time travel - if there was - we would have always had it ...
Peace, Brothers!
