Anything Faster than speed of light ?

Question

Is there anything which will travel faster than light, I know some say human thoughts, but anything else ?

Answer 1

Nope, nothing faster; not even thoughts (human or otherwise). Thought is an electro-chemical process. It can be mapped by special equipment that senses the electro-magnetic pulses in the brain. On the screen of this equipment, we can see thought as flashes of light starting in one part of the brain and spreading out to other parts. These flashes travel well under light speed.

Inertial mass m0 is limited to below light speed because at light speed v = c, the inertial mass m --> infinity. In which case, from F = ma, we'd have F = infinity or a = F/m = F/infinity = 0 and there would be no more acceleration. Even at below light speed, the force required to accelerate that last bit to reach light speed is more force than is available in the entire universe.

Bottom line, nothing goes faster than light, with one possible exception. Shortly after the big bang, our universe went through the so-called inflationary epoch or era. During that time, the theory goes, the universe itself (not the mass or energy of the universe, but the universe itself) expanded faster than light speed.

PS: The shadow answer is way off base. In fact, the shadow would lag the object of the shadow; like a stream of water lags behind the direction of a hose nozzle. The reason for the lag is that photons travel at the speed of light. So the lack of photons, the shadow, can go only so fast as the light that causes the shadow arrives at a distance from the source.

PPS: Tachyons are scifi. These imaginary particales came about when someone asked "what if" we could go faster than light. What would that mean? Tachyons were one of the thngs that came out of that question.

Answer 2

There is nothing that can travel more than the speed of light, if we are talking about a physical entity. If it has a mass then it can't travel at the speed of light, let alone more than the speed of light. As the body approaches the speed of light its mass will change to energy. At least that is what the principle says, but it is not easy to reach that high speed. So, if your mass is zero at light speed, then when you go even faster than that you will have a negative mass, LOL. To put it shortly, no body with a mass can travel that fast.
But I think a shadow can travel faster than light. Assume there is an ant walking in front of a lamp, and there is a wall very far away behind the ant. Now if you see how fast the shadow of the ant travels on the wall, then there is no physical law that will prohibit its speed form going beyond the speed of light. So I think it is possible. But shadows don't have mass, so the above theory is still valid.

Answer 3

At this moment it is not impossible for something to be FTL(Faster than light travel). Arguments for FTL have been made in support and in disbelief, it is believe to be improbable. Below is general information from most physics books you can get it off wikipedia.

* Matter becomes more massive as it accelerates, and at the speed of light, an object would have infinite mass.
* To accelerate an object of non-zero rest mass to c would require infinite time with any finite acceleration, or infinite acceleration for a finite amount of time.
* Either way, such acceleration requires infinite energy. Going beyond the speed of light in a homogeneous space would hence require more than infinite energy, which is not generally considered to be a sensible notion.
* Some observers with sub-light relative motion will disagree about which occurs first of any two events that are separated by a space-like interval. In other words, any travel that is faster-than-light will be seen as traveling backwards in time in some other, equally valid, frames of reference. Therefore any theory which permits "true" FTL also has to cope with time travel and all its associated paradoxes.

Hope this helps.

Answer 4

technology does not rule out speedier than easy shuttle.It rules out acceleration from sub easy velocity to easy velocity.no longer something rules out debris that start up by using travelling FTL.One such hypothetical particle is talked approximately as a tachyon. additionally,quantum entanglement is reported,yet no longer defined.The phenomena looks to coach there's a "point' of the universe the place time and area are phantasm,and on the spot communique between debris is reported fact,even if we don't comprehend the way it somewhat is achieved.Google them.have relaxing.Wild stuff

Answer 5

So far nothing. Dr. ECG Sudarshan has suggested some particles theoretically but not proved undoubtedly.

Answer 6

Tachyons
