Are there any theories

as far as are current understanding of physics its not possible to actaully travel faster than the speed of light. it might be possible to find loophole around that problem (wormholes come to mind) but they are 100s of years off.

There are no problems with traveling faster then C. The only problem is accelerating though the speed of light. If you could devise a system that allowed for you to increase speed with out accelerating then it would be possible. Unfortunately it does not seem possible to increase speed with out acceleration.
 
You can only move faster than light relative to another object, say two objects moving away from each other at .99C would appear to each other to be faster than light. Then again you couldnt see each other to notice. According to what i remember from the Ol college days actually traveling faster than light is impossible do to time compression and the inability to consume fuel for excelleration as SMOGZINN stated.

One other possible way of cheating and moving faster than light is teleportation, but then again, it might not even be you coming out the other side so count me out on that one...
 
You could also move faster than light provided that the light was in a medium such as water, where the spped of light goes from c to something like c/N, where N is the index of refraction of the material. So TECHNICALLY, a light particle/wave (whichever theory you subscribe to) will move faster in air than "the spped of light" [in water].

Hack-ish, but true 🙂
 
I read a news article not long ago about some scientists trying to do this somehow in a lab experiment, and apparently they thought it was indeed possible. I wish I could remember where I saw it.

There has also been some reasearch done about particles teleporting and stuff.
 
This is somewhat relevant to what you are talking about so i'll post here. Scientists in Ecole Polytechnique Federale de Lausanne have used Brollouin scattering to vary the speed of light. i.e. slow it down and even speed it up past the speed of light. This is within fiber optics within a vacuum so it would be quite difficult to travel on... but interesting none the less. Article here

So would the theory of light apply to light aswell? Or would light traveling faster than C show the theory is flawed somewhere?
 
Negative-mass tachyons? I read an article about them once upon a time. It was a lot of math basically showing how they theoretically COULD exist. If they do, they couldn't travel slower than the speed of light. But then again, that doesn't mean anything with positive mass could travel faster than the speed of light.
 
I think what people are usually wondering is if it takes 3 light years to get to point X at the speed of light is there a faster way..Not necessarly meaning traveling faster then light it self,,But covering the percieved distance in a time relitive to our own existance . .Kind of like moving from the Den to the kitchen ,,If the Kitchen is 3 light years away and space can be folded your travel time would consist of a 5 second walk ,,NOT because you are moving at light speed but because space has been folded to alow you to move across the distance in a few short steps . .

It is in this view of travel where the answers lie,not in mans ability to break the light barrier as we have done with the sound barrier,,because if breaking that sound barrier has taught us anything at all it is in the reality that the amount of enegey neded to physically move an object at such speeds requires to many bulky resources and is totally inefficient . . .

Mans biggest miss-calculation lies with our perception of distance and our insistance that the shortest distance between 2 points is a straight line . i was going to explain but think I am better off to let it get consumed at face value . . .

On actually being able to travel faster than light? Hypothetical, preferably from reputable sources?

hehe
l got a rep ! bad piss head ! and heres my theory !

the speed of light is just a speed and like the sound barrier humans drinking xxxx will break it !







xxxx = ozzy beer !

Hmm, it's been a while since I studied it but I believe from the point of view of an observer in one of the objects, the other object still wouldn't appear to exceed the speed of light...

That is correct, according to relativity.

 
Bell's Theory on faster than light travel is interesting, its not so much as traveling faster than light, he discovered something in the world of quantum physics () which allows particle A and B to communicate and change immediatly w/o time difference.

In the Quantum Theory, observer A's choice of what kind of measurement to make on particle A instantly changes the state description of particle B--a general feature of quantum theory called "quantum phase entanglement". In the theory a particle is represented by possibility amplitudes and relative phases. When the particles separate, so do the amplitudes, but the phases of particle A remain entangled with the phases of particle B. Any action on A--such as an observation--changes not only A's phases but the phases of B as well.

This action of observer A on distant particle B does not diminish with distance, cannot be shielded and travels faster than light. This (in theory) distant influence is unmediated, unmitigated and immediate. This (in theory) quantum connection between two particles once together now apart is a lot like voodoo--no known force connects particles A and B--just the fact of their once being together suffices to mingle their phases.

What he did was take two identical particles A and B, rotating in opposite directions, and send them off in opposite directions. What he did next deffies c. He changed the polarity of particle A (changed the direction it spins) in transit and particle B instantaniously changed its rotation to be opposite of A. And by instantaniously I meen at the exact same time the particles changed its rotation, the distance you may say wasnt large enough, but it was in miles. This is called quantum phase entanglement.

I would like to see some of these theories put to use link
 
Of course if you ripped a hole in the space-time continuoum, you could easily travel faster than light, but you would need a strong magic sword to do that.

Bell's experiment does not defy c in the classical sense, nor does it break the rules of relativity. No information is transmitted in the experiment and hence the laws of relativity remain consistent.

Bell's experiment does not actually involve changing the spin of either particle - it simply involves measuring a property of the particle, thereby collapsing its probability wave. It can then be shown that having collapsed the probability wave of one particle, that of another entangled particle simultaneously collapses, irrespective of the distance between them.

This breaks the Newtonian concept of locality but not Einsteinian Relativity.

 
I am fairly sure that if you are asking about whether you could out-strip a photon, and not taking into theoretical worm-holes, than you cannot, because if you were to even reach the speed of light, your mass would be infinite, and it would take an infinite amount of acceleration to do it. I am pretty sure that worm holes will be the sidestep man will take if we ever need to jump extremely, extremely large distances across the universe. Anybody read the halo book series?
 
I dont know about traveling faster than the speed of light, sounds hard; lets concentrate on shortening distance.
 
crap clicked the wrong button, anyway, I've been surfing the forums for a while, and felt like chiming in. found a theoretically possible method for ftl travel.
