How do we know that it is impossible and that nothing can go faster than the speed of light?

Question

because if something was going faster than the speed of light, we wouldn't even see it, because it would be going faster than the speed of light right?

Answer 1

The speed of light is more of an incident than a speed .
An incident takes time to achieve.
A photon moving through space travels as fast as it can.
The universe is made up of quantum entities this includes time pulses.
If you take the shortest time pulse and try to slit it,make it smaller it goes out of existence.
If you try to surpass the speed of light you are trying to force an incident to happen in a shorter time than can exist in the universe.

Answer 2

In theory there is such a particle that always moves faster than light called a tachyon. However they would have specific interactions with normal matter. Detectors have been set up by scientist to look for tachyons but none have ever been recorded.

As for normal matter, we know that nothing with mass can go as fast as light from Einstein's equations. These equations have been proven over and over again. For example, in particle accelerators, as they speed up particles to close to the speed of light time slows down for the particles. So the fact that nothing with mass can go the speed of light has been proven in many experiments. Since light is pure energy without mass it always moves at the speed of light.

Answer 3

Tachyons are hypothetical particles that always travel faster than light. You're right that we wouldn't see them, because it is thought that Tachyons cannot interact in any way with sub-light particles or fields. That's because of the following: if you take energy away from a Tachyon, it goes even faster than before. This would allow extraction of an infinite amount of energy from a Tachyon, and is therefore thought to be impossible. Tachyons can never "cross the light barrier" and go slower than the speed of light.

Answer 4

In fact, there's a theoretical partical called a 'tachyon' which can't go *slower* than the speed of light. But what Einstein said was that *information* could not move faster than the speed of light.

Answer 5

According to Einstien's special theory of relativity, traveling faster than the speed of light is impossible.

Answer 6

Umm.... i imagine you want a lesson in the conception of Relativity, youthful Einstein. "It takes a more beneficial % than a % of light for gentle to be unable to scape from darkish hollow?" in the starting up, that's believed that the speed of light is a continuing (interior a vacuum). A black hollow is so dense that it curves area-time back on itself, the position all paths of the interior of it lead it back to the singularity at its centre. i know you likely do not have the slightest information, so take a 2-length immediately line which has a level A and aspect B. no count number how not straightforward you attempt to flee that immediately line, you'll always finally end up at a level in that line (like operating around the planet Earth on a flat plane - it style of feels immediately on your concept, yet is unquestionably round). you'll finally end up in the very similar position no count number how not straightforward you attempt to run. next, attempt to positioned that idea of relativity on a 4-dimensional scale, further with the density/gravity houses of black holes, and per chance in the destiny we are going to figure it out at the same time.

Answer 7

We would never know. We may even have visitors that move faster than the speed of light.

Answer 8

coz scientists have tested over a million times with electrons and other subatomic particles. if u can make some thing go faster than speed of light then i guarantee u a Nobel prize

Answer 9

It's based on the idea that matter is ultra dense energy and that if it did travel at the speed of light it would break apart and revert into energy. similar to the way an aircraft falls apart if it travels too fast.

Answer 10

The mass would increse so what ever was going that speed would get crushed by gravity.
