Yes it does. If you were to reach the speed of light, you would "catch up" to the photon, and therefore the photon would have a speed of zero in relation to your frame of reference, contradicting the universality of speed of light postulate. <{POST_SNAPBACK}> No no no. That's the whole point of relativity. If you were to reach the speed of light the photon would still appear to be travelling away from you at the same rate - hence why time dilation was derived to stop any laws of mass and enegry conservation being violated.

Look it's just a matter of common sense. If it works for a clock then there's no reason it can't work for a human being. If I wanted to get to some point in the future faster than I am now, I merely have to travel fast.

If you don't understand the muon experiment that's okay - the atomic clock experiment should be easier for you to understand. Time actually slows down for the clock on the move. We have hard proof for it.

Intel are back on top again? I stopped following the race between them and AMD once AMD finally took the gold.

Can you not see how this time dilation can be exploited to travel faster into the future? The muon particles see the Lorentz contraction and hence manage to travel a shorter distance to get to the same point. When slowing down this distance expands and those particles have now found themselves in the future.

You're contradicting yourself. First you say it's a paradox and that time travel is an illusion. Then you say it only appears to be a paradox and that STR is indeed right.

A paradox by definition can not come into existance.

What you're describing is not time travel. Those are just some of the simpler demonstrations of Special Relativity. In the case of the clocks for example, what happens is that time passed slower for the faster moving clock than for the clock left on the ground. Time travel would be if, for example, time for the clock on the plane had instantly changed from say 12:00 to 16:00 of the same day. <{POST_SNAPBACK}> Wrong, one does not need to travel instantaneously to travel. Take moving a distance in 3D space. One does not jump instantly, that would be teleportation. With time dilation under the effects of STR one travelling close to the speed of light would move forward faster in time and hence time travel into the future. In fact we are all time travelling into the future now. If we weren't the present would remain the present and there would be no future. <{POST_SNAPBACK}> Yes, time moves forward, but for each specific person their time is always moving at the same rate. For an inertial observer time in their own coordinate system always moves at the same rate, hence there is no time travelling <{POST_SNAPBACK}> There's no logic to that argument. You're saying because somebody's internal clock looks the same to them no matter what speed they're travelling at time travel isn't possible. Nonsense. There's hard evidence that if you travel fast enough you can move to a point with less ticks than if you were stationary - else the muon detection experiment I mentioned wouldn't be possible. We have observed time travelling particles and you're arguing time travel isn't possible.

Because it's one way. I'm sure you've met plenty of people from the past.

I can put an end to this right now and say with all certainty time travel *IS* possible. In an attempt to prove Einstein's special theory of relativity two atomic clocks were synchronised. One was placed on a plane and flown at high speeds, whilst the other was left on the ground. When the plane landed the atomic clock on board was behind the clock on the ground. This is empirical proof that time travel is possible. Furthermore there is the famous experiment observing muon galactic radiation. These particles are noted to travel further, far further than there half-life permits. How? These particles travel close to the speed of light and hence time travel into the future to make the extra distance down to the surface of the Earth. There are very few serious scientists around that aren't conviced STR is indeed true, given the vast wealth of empirical evidence we now have. Just look at particle accelerators... they have to be kilometers long, where as Newtonian physics say they only have to be a few centermetres.

Who would have thought a movie based on such an uninspired, bland video game would get such bad reviews.

I'll go with this list. I've played through Super Mario RPG... too many repetative battles sort of ruin it but if you're into grinding activity its a pretty good game. Final Fantasy 6(3) would be my pick if you're you going the RPG route. As a final note I'd just like to add all these games play so much better on the original SNES than an emulator, so if you've got the choice go for the real deal.

God I'd hate to be stuck in a room with the people that don't like Futurama. You must be the most boring gits on Earth

These rumours have been going around from day one since the show was axed.

Just out of interest, how many of you make the effort to use public transport and recycle every last thing that's recycable? Do you switch all your lights and TV/Computer off when not in the room? Do you only switch the hot water on twice a day? Do you take your own bags with you whilst shopping for food? Do you use solar/wind/bio power to cut down your grid consumption? Have you taken measures to provide extra insulation to your housing? I'm guessing a lot of pro environmental people haven't done half the things on my brief of the top of my head list - so cut the "I care about the environment" crap, k thx Recycling a few empty bottles and newspapers once in a while does not make you a saint.

Downloaded Wedding Crashers. Had about one funny moment mid film... the rest was kinda zzzzzzz

Hunting just seems so pointless. If the animals were packing guns then yeah, your trophies are something to be proud of, but shooting defenseless animals... lol? If you want a real blood sport play RTS

And yet we're the dominant sex. Sucks to be you!

It was discovered indepentandly by other nations, but I give them 10 points

Oh I misread the question... who "should" it belong to. Erm, whoever finds it first I guess. If they want to share that's up to them.

Law of the Jungle. Belongs to whoever can take it.

But that's what makes them so good when you're a kid

If you were a programmer you'd be wondering what your point was.

I suppose one thing surgery can do is make your nose bigger.
