what is faster thean the speed of light?

Liight, even though it's a wave, can sometimes act as a stream of particles, which we call photons. These can travel at "c"--the speed of light--because they have no mass, which sets a handy precedent: anything massless can travel that fast. But what about faster? Interestingly, the equations are symmetrical; it takes infinite energy to reach the speed of light, but not to exceed it, so while there's no way for a slower-than-light particle to become a faster-than-light one, a particle which starts out faster than light--and stays that way--is permitted by the theory. In 1967, physicist Gerald Feinberg even coined a name for such particles: the Greek word "tachyon" (roughly, "swift thing").

Do tachyons exist in the physical universe? If so, their masses would have to be imaginary, meaning a multiple of i, the square root of negative 1. That would be weird, and difficult to measure--no tachyon of any sort has ever been detected. Probably. But there is a subatomic particle--the neutrino--which has caused some scientists to wonder. Neutrinos are produced in great quantity by the nuclear reactions inside our sun, and every other in this star-spangled universe. They travel at or near the speed of light, meaning their mass--if they have one--must be something very close to zero. But it's hard to measure, and sometimes the sun's stormy surface kicks out a burst of neutrinos which we observe several seconds before an obviously related burst of photons. So yeah, the evidence is sparse, but it's tempting to speculate the neutrinos are maybe going a little bit faster than "c."

There are a few other things that can go faster than light, by virtue of not being "things" at all. The spot from a laser pointer is one example--shine it at the wall in front of you and you can make it move around quite rapidly. The farther the wall, the faster (and dimmer) the moving spot; shine it at a target thirty thousand miles away and you can easily move it faster than "c." The individual photons, of course, still move as slowly as ever--it's exactly like waving a firehose around so that the splash of its impact travels faster than the speed of the water through the hose. The splash is a process, not an object, so it isn't constrained by relativity.

Nope, There isn't.

You can slow the speed of light down in experiments, but that does not allow anything to really go faster than light.

There is a fairly long and involved explanation of why that is so. Searching for my previous answers to this same question can provide you with that long explanation.

Essentially remember this, Nothing material (that is, made of matter) can ever travel faster than lightspeed in this universe. It's not a matter of gaining more speed. Its not a matter of "It just hasn't been done yet". It cannot be done.

Now, There are spooky "Action-at-a-distance" effects in Physics that appear to violate this law, but due to their quantum nature, do not.

Actually there is nothing faster than the speed of life, if there was than it would defy the laws of physics. So even though on tv shows and things you see "People" going faster than the speed of light, that's just not possible. Maybe one day in the future we might just find some source of speed faster than light, like in Futurma, but as of now, there is nothing known that is faster than the speed of life, And if something like that was found, the laws of physics would have to be rewritten.

Nothing we can measure, but I would guess that thought is the only thing faster than light.

PS, Use the spelling checker!

the speed of a truck moving 30 mph.

the cost of sounds is approx. 3 hundred m/s (one thousand ft/s), mutually as the cost of sunshine is 3 hundred,000 km/s (approx.a hundred ninety,000 miles/s). subsequently, the sound arrives some million/3 of a 2d after the corresponding flow, i.e. starts to be recognizable.

nothing is faster than light ,it is a extrem speed in world.

Light in fiber.

Also sound in certain conditions. Look at http://nicklevay.net/misc/memeimages/001/mtsu-soun...

Don't know. But I DO know that the sharpest thing in the world is a FART! It can go right through your underpants without cutting them!
