Is there anything in the universe that travels faster than light?

Yes, it is thought that neutrinos travel faster than the speed of light-In fact, it is thought that the speed of light is the *lower* speed limit for neutrinos.  Thought is not particularly fast,and is measurable at a few hundred miles/hour.  Einstein's theory says that nothing can be accelerated to the speed on light, and only refers to massive particles and objects.  The theoretical connection between particles created together (paired particles) seems to obey no speed limit, and react instantly regardeless of the distance, but we are not sure if this represents somethign traveling between the objects, or a connection that exists in a different plane or dimension.

MitchHellman has the best answer!\n\nBut just cuz....a tachyon (theroetical particle) cannot travel *slower* than light. An effect called phase velocity (wave mechanics) can also travel faster than light, but these things are not real in our normal sense of the word. But these are some things people do discuss which have this property.\n\nOtherwise.......no.\n\nlol

Yes, through wormhole and warp drive. A wormhole should be able to connect distant locations in the universe by bending spacetime, allowing travel between them that is faster than it would take light to make the journey through normal space. \n\nA warp drive would be a mechanism for warping space-time in such a way that an object could move faster than light.\n\nIf you would like to learn more about wormhole, follow this link http://en.wikipedia.org/wiki/Wormhole

I believe it is expanding.  The speed og light, c, is the cosmic speed limit for objects or radiation within spacetime.  Spacetime itself can (hypothetically) expand faster than c, though what the limit to this might be I don't know.  Special relativity is not violated since there is no object being accelerated.

Particles entering earths atmosphere have velocities close to speed of light but not faster, theory of relativity states that particles that have mass can not travel faster than light, only particles with no mass can travel the speed of light and higher(see question about tachyons in Physics). True nature of black holes is still a mystery for scientist, but one thing for sure is that maximum speed of particle entering it is the speed of light, but time and space are distorted in black hole so it looks like it has a different speed. You should first understand Einstein general relativity to understand black holes.

Huge.\n\nThere is an edge to what we are able to see and could ever possibly see in the universe. Light travels at 300,000 kilometers per second. That's top speed in this universe—nothing can go faster—but it's relatively slow compared to the distances to be traveled. The nearest big galaxy to our Milky Way, the Andromeda galaxy, is two million light-years away. The most distant galaxies we can now see are 10 or 12 billion light-years away. We could never see a galaxy that is farther away in light travel time than the universe is old—an estimated 14 billion or so years. Thus, we are surrounded by a "horizon" that we cannot look beyond—a horizon set by the distance that light can travel over the age of the universe. \n\nThis horizon describes the visible universe—a region some 28 billion light years in diameter. But what are the horizons of a civilization that inhabits the most distant galaxies we see? And what about galaxies at the limits of their vision? There is every reason to think that the universe extends a long way beyond the part of the universe we can see. In fact, a variety of observations suggest that our visible patch may be a small fraction—maybe an infinitely small fraction—of the whole universe. \n\nThis view of the universe fits with the currently popular idea that the universe began with a vast expansion of size. The idea describes a kind of undirected energy present in the vacuum of space, called scalar fields, that somehow got channeled into a process called "inflation." By conservative estimates, the universe expanded so much during this period that something the size of an atom inflated to the size of a galaxy. \n\nIf this grand idea is correct, then the universe is larger than we ever could have imagined.\n\netc...

It is not possible for any particle that has mass to travel faster than the speed of light. The reason has a lot to do with relativity. Because the faster you go, the slower time passes for you. So if you are at 80% of the speed of light, and launch a projectile in front of you at light speed, because of your slow passage through time, it will still appear to you to travel at light. Everything is relative, and because of that, certain constants like the speed of light never change.\n\nAlso, a particle with mass would achieve infinite weight at light speed. Since you can't obviously exceed infinite weight, you can't exceed light.\n\nThe ideas behind things like "warp speed" don't propose actually traveling faster than light. What they propose is taking shortcuts through space, kind of like skipping a stone across the surface of the water. Even "warp speed" is subject to the laws of relativity.

No! It would take someone of a stature in physics greater than that of Einstein to claim that the speed of light is faster or slower in other parts of the universe.  The speed of light is constant\nthroughout the universe and the reason that light cannot escape\na black hole's gravity is because the gravity is so strong. And that's due the amount of mass of the black hole.

Looks like a controversy here....but no, gravity does not travel faster than light, it would take eight minutes before the earth's orbit changed.\n\n(If gravity was instantaneous, then it would be possible to use that to send messages faster than light!)

theoretically nothing can travel faster than light which is 186,000 miles/sec, but i don't agree with that theory at all

Interesting question.  Actually, it may be that 'darkness' is faster than 'light.'  In the universe, there appear to be vast regions of nothingness, like the inside of soap bubbles, that are expanding in volume as fast, or even faster, than the speed of light.  \n\nIt seems like the presense of nothing (or more precisely, the lack of anything at all) has a very weird effect on the 'fabric' of space-time, causing it to expand more rapidly than space which is near to 'stuff.' \n\nThis is called 'zero-point vacuum energy' and plays an important role in modern views of cosmology.

i think its very much possible to travel at the speed of light, its just that we would need an extremely strong processor (like a fax machine) to break down the matter that we are made of into energy (E=MC^2) and then after reaching the destination just convert the energy back into matter. (not possible with the technology we have today)

One of the fundamental assumptions of relativity is that there is a finite speed of causality.  Usually this assumption is stated "the speed of light is a constant", but I think the finite speed of causality statement is a better way of looking at it.  So if something could travel faster than the maximum speed of causality, then it could make events happen before it caused them.  That is assuming that relativity is true and that causality is a flexible concept.  If you assume that causes must preceed effects then there are two possibilities for the hypothetical object going faster than light.  1. there is a maximum speed for the object that is going faster than light, so just raise the speed of causality to that new speed and keep relativity  2. there is no maximum speed limit for the object and influences can travel instantly, thus one of the fundamental assumptions of relativity is false and we need to throw out the theory

Some things are already able to reach the speed of light such as photons (light).\n\nAccording to Einstein's theory of relativity though, it requires an infinite amount of energy to reach the speed of light.\n\nSo we can't ever make a spaceship go at the speed of light.\n\nWe are currently trying to make atoms move at the speed of light but we only get close with particle accelerators.

The question is irrelevant since nothing with a mass can travel at light speed.

By traveling faster than the speed of light.  As velocity approaches the speed of light, time slows down.  Traveling faster than light speed then - would make you travel back in time.  Theoretically, it is possible (according to the theory of relativity) but scientifically, it doesn't seem possible.

As your question states 'Which travels faster than sound,light and wind?', there's no answer to that because Light travels the fastest in the universe.
