Didn't you watch BSG?  Their ships had FTL capabilities!!!

The Fongoids screwed it up, so now the great clock basically stops us from being able to do it. At least that's what I've learned from A Crack in Time so far.

Actually in quantum phsysics (as far as my brother has explained it to me) time flows in both directions, it's just that we seem to be hard wired to only perceive it flowing in one direction. There is an hypotyhesis floating around that sugggests the universe works at the micro scale in part by individual particles travelling through time to interact with it's past or future self.

There is also a theoretical mechanism for travel between past and future involving creating wormholes and having one end of the wormhole travel around at near light speed so that it winds up existing ahead of time of the other end of the worm hole and thus you can tyhen freely travel between past and future. But the earliest past you can travel back to is the time when the wormhole was first created. So you still can't live the dream of taking a minigun back to the time of the Crusades and laying waste to the heathens, or the infidels (depending on which side you like best).

More or less correct: basically our quantum laws respect a CPT simmetry. That would mean that you can't distinguish an electron from a positron (its antiparticle, C simmetry) traveling back in time (T simmetry), seen in a mirror (P simmetry).

Or, just for fun, that you can see the same diagram and

1. read it as showing an electron and positron annihilating, their energy and momentum released into a photon, or
2. read it as an electron hitting the void, emitting a photon in the collision to conserve energy and momentum and ricocheting backwards in time. That would be what you before called a positron.

Fiction.  :-p

Scientists are pretty sure there are microwormholes that exist all over the place, they just don't believe one could ever be big enough and large enough to travel through.  They basically make a feedback loop of radiation and destroy themselves instantly (or at least that was the way I understood it, it has been a while since I read about this stuff).

Naw... if you watched it, BSG actually took place thousands of years before present day... we are the decedents of space exploration!! 

I just watched that from the link that Kratos_35 provided. It is mind boggeling.

That's the one where he throws the party for the time traveler right?  Yeah, that was a fun show.

Well , I think it is possible to go forward in time , but i don't call it time traveling. You're actually going to a different time zone , space , and increase the effect by moving very very fast 99.9 % speed of light. When you return , you didn't really go forward in time. Everything about you and around you ages slower. Also the material where the possible super light fast space ship could be build of would be aging slower. So I see it more like you're aging less fast and expierencing time less slow. It's a bit confusing , I know. But I think it's more a personel opinion. I compare it to traveling on earth to a different time zone where it's 8 o'clock will in your zone it's 4 o'clock (4 hours earlier) and you travel to the other 8 o'clock time zone and say 'Hey , i've traveld in time'. Only different is that it is the 'human time' and your aging won't slow down. Time as we know it has been created by humans as a appliance to discribe things that happend are happening or will happen.

BUT I think it is possible to see what will happen in the future. But the problem is , what is the function ? You can't go back in time so it's not like you could warn for disasters and so. When you travel to the future , you will stay there.

If you where able to travel into the future to see that a hurricane killed 1000's of people , you go back in time to make sure they evacuate the area , the future won't be the future as the time traveller saw it when the 1000's of people died. So there is another paradox.

Also , you don't really travel in time by the for now 2 known methodes that theoratical will work (Black hole , lightspeed). Because the time on earth stays the same. So you are going to a place where time is going faster than on earth , you go very very fast to multiply the effect and then you return to the place where time is going slower.

And 'direct' time traveling in the future won't be possible also. With direct I mean like stepping in a sort of gate and you are directly in the future with NO time past neither on earth or time that effects you. Because then , there would be no future because the past that shapes the future hasn't happend yet.

So if you travel 400 years into the future and 8 minutes have passed on earth and like 2 minutes are passed that you expire , would that be possible ? Because there is a big gap between those 400 years and 8 minutes on earth that never happend , not yet. So you would end up in really nothing because there is nothing yet. If there is , than you've got proof that EVERYTHING  is 'planned' to happen and a thing as coincidence also wouldn't exist. But then there is no one to tell because a part of the past still has to happen. No past no future. So I think you could call it a paradox so it will never be possible to travel directly into the future if it hasn't happend or is happening.

Travelling above light speed is also not possible otherwise you would be als in nothing because the light of everything hasn't reach the point where you are at that moment. So you also couldn't be there. Because it still has to happen and so I think that even time can't travel faster than light. You could also say that time has the speed of light. Or maybey even a bit faster to stay ahead of light otherwise light coudn't exist if there is no time. Most probally they are parralel to each other.

Excuse me , i'm not a prof or doctor or anything. I'm 15 years old so i'm still on school but that is how I see it and some theories I thought about.

Stephen Hawking held a party for time travelers to come back and socialize with him.  No one showed up.

I'm gonna go with Time Travel will never be possible, at least not to the past, or not in any controllable fashion.  Maybe someday if we figure out wormhole travel there could be some goofup that sends someone to another time as well as place.  Until then I think whoever said the "near light speed travel is close to time travel" is right.  You can actually do that now with real space shuttle travel, the aging difference just isn't as drastic.  I think it's something like an earth day goes by every 7-9 hours when traveling at high velocity in a space shuttle/rocket.
