Can tachyons go faster than light speed?
Some theories suggest that tachyons could travel faster than the speed of light, but they have not been observed. In current physics, nothing with mass can reach or exceed the speed of light.
What can travel at the speed of light?
Nothing can travel at the speed of light, only light itself, the closest we have ever gotten to the speed of light is 99.9 %, we have accelerated particles at very very close to the speed of light using the LHC (Large Hadron Collider). The only thing that can go faster than the speed of light, is Space.
What was the first rocket to go faster than the speed of light?
Nothing has ever gone faster than the speed of light.
How did early astronauts travel the speed of light?
Nobody has ever traveled at the speed of light, and I can promise you that nobody ever will.
Why can't anything travel at a speed faster than light?
Various reasons, most of them related to the Special Theory of Relativity. 1. To speed something up so that it even reaches the speed of light (from an initial speed that is slower than light) would require infinite energy. (However, this doesn't preclude hypothetical particles that ONLY travel faster than the speed of light.) 2. If it is were possible to travel faster than the speed of light, it would also be possible to travel to the past. This is due to the definition of "simultaneity" in the Special Theory of Relativity. If you ever read stories about time travel, you would know that time travel may result in many contradictory situations, so it seems doubtful at the least.
The first person to fly faster than the speed of light was?
No human has flown faster than the speed of light, as it is currently considered impossible based on our understanding of physics. The speed of light, approximately 299,792 kilometers per second, is the cosmic speed limit according to the theory of relativity.
What is the name of the first plane faster than the speed of light?
Nothing has ever been manufactured that could move anywhwere near the speed of light, and according to the best current science, nothing in nature can ever move faster than the speed of light.
Do subatomic particles travel faster than speed of light?
No, nothing known can travel faster than the speed of light. Theories do predict a type of "nonmatter" called tachyonic matter that cannot travel slower than the speed of light, but nothing like it has ever been discovered. It is actually likely if it did exist at the time of the big bang, it almost certainly left the universe almost instantly because the big bang expansion could not keep up.
Is light the fastest thing ever?
Tachyon is faster because when it loses energy it gets faster and its lowest velocity is the speed of light.
Can a space shuttle travel faster than the speed of light?
No 1). Nothing can. 2). No space shuttle ever came anywhere close to that speed. 3). No space shuttle can travel at any speed now, because that program has ended, and the remaining shuttles are in museums.
Would man ever coceivably travel faster than the speed of light?
No. Anything EXCEPT for light that travels as fast or faster than light would need a near infinite amount of energy, and I expect that near all of us know that near infinite energy is and was only available when the universe was compacted to smaller-than-atom size, as it contained all the energy that's ever existed. Even if we did manage to travel at or faster than light-speed, we would travel back in time. That means the faster than light we travel, the farther back in time we would go. Knowing that, so far, we know for a fact that faster-than-light travel has not been achieved, as we would've had impacts on this time period. Some believe that the pyramids were built by alien's, but I believe that we were the ones who built it, but us from the future. Does this answer your question?
If something started out already traveling away from us at greater than the speed of light will its light ever reach earth?
No. Speed of light is constant in all frames of reference, even if you are also traveling at the speed of light, the photon will speed away from you at the speed of light. When you see an object, what is happening is that photons are reflected off the object you are looking at and bounce back into your eye. However, if you are traveling faster than the speed of light, the photons can never reach you to start with, hence, you are invisible until your speed decreases to something below the speed of light. It is possible to travel faster than light in many ways. First, if you have a negative amount of energy, you will always travel faster than a speed of light. Another possible way is to compress the space in front of you, then move to your destination before re-expanding the space you have just past.
