What is faster than light?

Question

didn't astronomers or scientists found anything travels faster than light?What is it? and how much faster? does that destroy relativity?

Answer 1

O.K., my gentle yet obviously Google-impaired friend. The short answer is no. Period. End of Story. Goodbye. See you later!

And what about that grammar? Are you in a hurry? Too busy to write correct sentences? What would your mother think? I'm embarrassed for her. I'm sure she didn't raise you to be like that.

May I suggest the utilization of a spell checker or a dictionary. It will help in preventing people from initially assuming that you are probably a witless git. Of course, what you say (and how - grammar) will have a profound secondary effect on this impression and I can't help you there. However, being ever the eternal optimist, here's a link to get you started:

Answer 2

Cosmologist and Astronomers have determined that the recession velocities of the galaxies in the Universe is greater than the velocity of light.
The Relativity theory does not mention that things cannot travel faster than the speed of light. Einstein's first postulate implies that in a local frame of reference the Velocity of light can be considered as constant if the effect of of a gravity field is neglected.
Einstein in relativity allude that mass structure in the Universe cannot be accelerated to the speed of light. Nothing is mentioned of the constant recession velocities of the Galactic expansions in the Universe,except he alluded to a cosmological constant. At that time he had not understood what he had discovered.
Relativity is only a model.And what the model predicts should match observations ,provided that the interpretation of the observations are correct.

Answer 3

Theoretically, it is possible that there are particles faster than the speed of light called tachyons. They work in the inverse of photons, the greater the energy they have, the slower they are (If memory serves).

They need to have an imaginary mass, which is a theoretical mass of certain kinds of particles. Nothing is certain yet, but it is not proven that things will go past the speed of light, just that they might be able to.

Answer 4

Nothing is faster than light in a vacuum.

However in other mediums there can be things that go faster than the speed of light in that medium. For example: Cherenkov radiation are charged particles that travel through an insulating medium faster than light can through the same medium.

Answer 5

Time is linear, a single direction - present to past. The physics trilogy describes the basis of our reality, and it gives a clue as to why things operate as they do. The trilogy is: E = mc2, m = E/c2, and c2 = E/m. The last is that of a field of gravity, which is a field of physical time. This equation describes the "c^2" concept as being an energy/mass relationship, while the first two describe the basis of our existence itself is this very same value of "c2".

In the first equation the value of "c2" is the multiplier and in the second the divider. In each of these it is the basis of the equation itself. What this means is that all forms of energy and mass are composed of this value. Our universe and all within are composed of physical time "c2". It is for this reason the present moves into becoming the past at the rate it does, and this rate of change is the same throughout our universe. Every event moves from "present time" to that of the "past", which means our universe moves in a single direction.

Mass moving to the speed of light would change into electromagnetic energy. Mass would change from being a three dimensional entity into becoming that of physical time. This may be thought of as m = c^3, or a cube of time. A cube of time "c3", as I remember, is that of 1 kg. or 2.2 lbs.

Were all the mass of our universe converted into electromagnetic energy (of which it is composed), then it would have changed from a three dimensional universe into that of a single dimension. At that instant physical time would have ceased to exist, for it requires the presence of a mass to form the concept of time. So, nothing is able to exceed the speed of light, for it it did the object would no longer be existed in our universe.

Answer 6

It has being said that you can bend space and close the distance to where you are going, to the point of geting there faster than light could over the whole distance.

Answer 7

Scientifically, we have not found anything faster than the speed of light, but that doesn't mean something isn't, it's just we haven't discovered it yet.

Answer 8

Cerenkov radiation - the blue glow of the reactors in Star Trek. But of course, only in that medium is it faster.
