According to sources, sources, cosmic rays are slamming into the atmosphere at 99.99999999999999999999% the speed of light. If that isn't proof that you cant break the sound barrier using normal means (aka without moving the entire universe), I dont know what is. Oh wait. Yah I do. Math is proof :P . But this is physical evidence.

 

-_-'.

 

 

 

Of course disregarding the fact that it's impossible, both realistically and philosophically, to move the universe (as it's the universe for Christ's sake, you can't move it unless there's something outside of it), if everything but you were to be moving, it still wouldn't be able to pass the speed of light. It's matter too ya know.

 

 

 

Oh, and you meant "light barrier", not sound barrier, right :P ?

 

 

 

Uuh, yah. I meant the light barrier. Not the sound barrier. And it is "possible" to move the universe faster than the speed of light. I forgot where I read it though... It just its't possible for anything in the universe to move the universe; let alone move it faster than the speed of light. But it is possible with a large enough ammount of energy. I beleive it includes something like moving the universe while moving yourself at the same time.

Einstein taught us this Energy = Mass x Speed of light^2

 

 

 

this basically means that the faster you go, the more energy you need (makes sense, don't it?) And that amount of energy approaches infinity as you begin to get close to light speed. It requires infinite energy to accelerate a mass to the speed of light, unless that mass is 0 (which is nothing)

 

That equation has nothing to do with what you just said.

 

 

 

they always told us in Physics intro that thats what that equation ment.

 

 

 

everything else should be right though, atleast in theory

No offense or anything, but I don't think that made much sense :-s .

 

 

 

You can't "move the universe", just the matter in it, and moving the matter around you doesn't make you go any faster.

2) Please stop using E=mc^2 as the formula for light speed, it has nothing to do with it. E=mc^2 is the rest mass energy equation, more commonly knows as the equation that tells you how much energy a nuclear weapon gives off when a mass "m" is detonated.

This sounds like an episode of Futurama I saw a few years ago. If that's where you got it from... :lol:

that is from a Futurama episode. If you could move the universe, you will still need infinite energy to get it to the speed of light, it would just have much more mass to accelerate. that would be a rube goldberg solution

Time travel is absolutely, undeniably impossible. Period.

 

 

 

 

Nothing is Impossible in this universe

 

 

 

Whats would happen if we travelled so fast, we came to the big bang period :shock: , What would we see before the big bang??

 

-.- Honestly now. You really believe that?

 

 

 

Okay, not really going to go into it but just for kicks I'll list somethings that are totally and completely impossible, even if your a god.

 

 

 

-Light striking a perfect planar mirror and having an angle of reflection that isn't equal to the angle of incidence.

 

 

 

-A two dimensional triangle where all three angles don't add up to 180 degrees.

 

 

 

-A Iron atom undergoing fusion with a Seaborgium atom and not only absorbing energy, but having the product be a single Lithium atom.

 

 

 

 

 

Simply impossible. Nothing else to say really.

All this talk of moving the universe is just completely illogical. Where could you move the universe to? It doesn't make sense.

Let me tie that question with the following..

 

 

 

:|

 

 

 

1) The big bang, you know the thing where the entire universe exploded? Yea, well that had a bit of of energy behind it wouldn't you say? The galaxy fragments exploded outward at ~99.999% the speed of light. Let me rephrase that. The energy of the entire universe exploding... was not enough to break the speed of light. Good luck with that one Germans.

 

 

 

Seriously? That sounds right logically, but I want to see some kind of source. :-k

 

Nice catch, I did look it up, and it appears I was wrong... sort of.

 

In the first few milli seconds after the big bang things were 'moving faster than the speed of light', but that's because the universe was being ripped in half and moving away from each other. It's hard to explain since there was no real reference point (what do you consider to be standing still when the universe is being ripped into pieces and flung in every direction?). But in a way things could be defined as realitivly moving faster than the speed of light.

 

Imagine. If one piece was flying "left" at 99% the speed of light, and another piece was flying "right" at 99% the speed of light. Now stand on one of those pieces, and look at the other peice, to you it looks like it is going 198% the speed of light (99% light speed + 99% light speed).

 

 

 

That's not exactly what happened but the whole thing is really hard to put to laymen's terms, I hope it made sense. :|

Really? I mean I quite clearly could be wrong here, but I thought that special relativity showed that the speed of light was fixed. I.e. if you were to ride on a motorbike at the speed of light and shine the beam of a torch in front of you the two speeds would not add so that the beam of light was moving at twice the speed of light. I thought the speed of light was constant in all frames of reference. Although, it's entirely possible and probable that relativity breaks down at singularities like the big bang, but I didn't know much was known about what really happened.

You are right about the motorcycle example, but I think this is different since the universe is the thing that's moving... this is really hard to explain

 

 

 

I guess the balloon example works. Imagine two bugs on a balloon (the universe) now blow up the balloon rapidly, the two bugs are moving apart from each other very quickly... yet technically they aren't moving themselves, the universe itself is moving them.

if this is true then the theory of time machines = reality? :shock:

 

Not really. You can't physically go back in time. If you use the Pluto example you could see 5 hours into the past, but if you actually traveled back to earth you would be back at the present, since what you saw on Pluto wasn't the actual physical past, it was just a delay in the signal. It's hard to explain but if you think about it, it makes sense.

 

You can look into the past, but you cannot go to the past

 

 

 

 

 

Time travel is absolutely, undeniably impossible. Period.

 

Not exactly, you can travel to the future. True going back in time is pretty much impossible, but traveling to the future is possible, but you could never go back to the "present" if you did. Going to the future involves a process that isn't really related to what we were just talking about. In short, if you go fast time slows down. If you ride in a plane all day and your watch was an atomic clock, by the end of the day your watch would be about a second slower than an atomic clock that was on the ground. :uhh:

 

 

 

This doesn't have any big implications but if you traveled like 10x the speed of light time really slows down. If you flew in a circle at 10x the speed of light for about a year and then came back to earth, what was 1 year to you and your ship was actually something like 1000 years to everyone else on the earth :-s

 

 

 

I saw something on the science channell about this but they said that if you went in a circle it may cause a strange effect that takes you into the past, and to go to the future you would have to go a straight line

Thanks, it makes sense now. Personally, I still think we can reach the speed of light though. There's no solid proof that we can (because we haven't), but also no proof we can't (it's all based on theory and it would be much harder to actually prove that we can't).

I agree, I believe it is remotely possible to surpass the speed of light, probably by using the universe shift or wormhole method.

 

 

 

Saying anything is possible is just silly, but I think the speed of light rule is one of those grayer areas. Granted I doubt the Germans did it, but I think in the nest 15 or so millennia someone will find something...

Silly Germans got all drunk again. Its not the vase they broke this time during a beer fest, its the speed of light :-k

Ah yes, I think I see what you mean now. Although...ah this is confusing.

Your friend would pick up the phone a year later...

 

 

 

So you would be sitting there on the phone for a year?

I find it unlikely, but then it might just be possible, science theories always seem to come and go. I remember when the supposed discovery of cold fusion a few years ago now. Nothing interesting ever developed from that and I doubt anything ever will from this.

If you at the speed of light, time (from your perception) will stop. In theory, if you ever managed to continue the trend of acceleration (which is impossible, since you cannot produce more than infinity of anything, let alone infinity), beyond the speed of light, time would move backwards. However, I'm not sure of the implications of this, and anyway, beautiful the concept of time-travel is, should we really strive to achieve this, for fear of the creation of paradoxes?

The fastest speed ever is exactly the speed of light.

 

 

 

What are they teaching kids these days?

And no, Futurama doesn't count :P .

Lol, I remember that episode :P .

 

 

 

And I dont have any sources. I saw it on a television show once a few months ago (and no it wasn't futurama). I guess it is possible that they were wrong though. I might as well just forget about it though. But I think it had something to do with the fact that the faster matter moves, the slower time goes for it.

 

 

 

Edit:

 

I might add that it is more than likely that is is complete crap. Saying it is "possible that they were wrong" is a bit of an understatment.

But I think it had something to do with the fact that the faster matter moves, the slower time goes for it.

 

 

 

It's time dilation, part of relativity. At least I think it's time dilation.

Lol and to think we were talking about this in physics the other day.

 

 

 

To all the people who think travelling back in time is possible you cannot be more wrong. As trapical said it is 100% not possible to go BACK in time. Do you want proof? Well out of the billions of billions of years life will go on wouldnt someone have already come back by now ;)?
