Do you think there is another type of of substance that can travel faster than light that we havent disovered?

Question

Is light the fastest moving thing that we've got or do you think there is something else that can handle higher speeds?

Answer 1

if something is faster than the speed of light it defies the theory of special relativity and hence will disprove the theory and this is not really possible.
although it is known that De Broglie phase velocity of a particle is always >c it does not defy the theory as the De Broglie group velocity(which is the practical velocity at which the waves will move in a wave packet) is always

Answer 2

There is an absolute answer to what you seek. It is found in the physics trilogy. The trilogy is E = mc2, m = E/c2, and c2 = E/m. The last is that of a field of gravity, or a field of physical time. It is the first two concepts we are interested in, and in particular the "c^2" aspects of them. Notice that in the first equation it is the divider and in the second the multiplier. It is the basis of each equation. What does this mean? The c2 value is what we exist of. It describes how quickly the present becomes that of the past. Everything in our universe moves at the speed of "c". In mass this value is maintained just as in an electromagnetic wave moving through space. This is evidenced also when electrons come apart into separate waves of gamma radiation. Whatever does not exist within our universe having the value of "c" does not exist to us. Were a mass, or form of energy, to move at a speed less or greater than that of "c", it would no longer exist in our universe, but in another having a "constant" equal to that particular mass or energy.

Just as mankind cannot exceed the speed of light, neither is mankind able to leave "present time". For it is present time "c" of his universe that that he is totally composed of.

There are a few short writings at http://360.yahoo.com/noddarc that may be of interest in understanding time. They are, "The Twin Paradox" and "Concepts Concerning Time, Gravity, and Energy".

Answer 3

If the existence of parallel universe is proved then, may be "something" might be there which can travel faster than light in that universe. As far as our universe is concerned NO nothing can travel faster than light... at least according to Theory of relativity. There are few physicist who are trying to prove that speed light can change.

Answer 4

No. If light didnt exist, we would still know the same speed as the fastest anything can travel because other not so popular things travel at the same speed. Gravity for instance.

Answer 5

The original space-time pulse that launched the universe was of minimum size and duration.
If you try to reduce either they will go out of existence.
The speed of light is an incident,an incident takes time to occur.
To attempt to increase the speed of light you would be trying to cause an event to happen in a space of time that cannot exist.

Answer 6

There is the Bosian String theory postulate, not held in much respect, of the Tachyon.

Should there ever be any evidence of Tachyons you can beat there will be postulates of other similar particles.

Under the theory a Tachyon ALWAYS travels above light speed.

Answer 7

I think of it this way. Light is the fastest thing in this dimension. The way I look at it is we may find some shield that may let us around this block.

Answer 8

At this 2nd, we are receding from the furthest galaxies far previous the cut back of observability, speedier than the fee of sunshine. in the early universe, area superior many hundreds of cases speedier than easy whilst it went with the aid of an particularly short inflationary section. area in our accelerating observable universe is destined additionally enhance speedier than easy, such that each and every person different galaxies, different than those gravitationally sure in the Milky way / Andromeda gadget, will at last disappear outdoors the cut back of observability, merely as those furthest galaxies did because of the fact of inflation. Einstein's particular relativity facilitates area to enhance speedier than easy, yet no longer for a physique with mass to holiday with the aid of area speedier than the fee of sunshine in a vacuum.

Answer 9

There is a theoretical particle called a Tachyon. If proven to exist they are FTL particles. See String Theory--Tachyons

Answer 10

Never say never. Never set limits without proof of limits, and even then, be willing to search some more, push outward on limits.

Unfortunately, we haven't run across anything faster, so it is of little use to opine as to what the faster medium might be until we encounter it.
