The GPS system is a network of devices that communicate by radio. Radio signals
are electromagnetic radiation, just as light is, and they travel at the same speed
as light does.
Light travels at 299,792,458 m/s as both a wave and a particle. Light demonstrates aspects of both. It does not require any sort of medium to travel.
There is many thoughts about time travel one theory is that if you travel faster than the speed of light you can see into the future and sort of 'jump' into the future and then travel one again faster than the speed of light to see into the past and then 'jump' back of course this is just a theory and has not been proven or said to be true and who knows the future seeing might take you to the wrong time so if your traveling back into the past you might go TOO far back to the past, no-one knows if this is true it has been tried but has been failed to go faster than the speed of light
yes, the ability of light to travel through the cable is what makes it useful. There is not some sort of hole in the center of the cable, it is a solid glass cable.
Sort of. The meter is currently defined to be exactly the distance that light, in a vacuum, travels in 1 / 299,792,458 of a second. The result of this is that the speed of light is DEFINED to be a certain value (299,792,458 meters / second); the meter is derived from the speed of light. Of course, you can't legislate to make the speed of light in a vacuum faster or slower; or rather, if you do, light won't care about such legislation. The legislation only affects the numeric values assigned to such a speed.
No material object can exceed the maximum speed of light, 299,792 km/second in a vacuum. However, energetic electrons can reach extraordinarily high speeds, and in water can go faster than (and overtake) light radiation, which is slowed to around 224,910 km/second.It is theoretically possible, however, that one could somehow change reference planes and cross a distance faster than the light does that remains in that reference plane. This would not be going faster than light, but merely taking a shortcut.
A probability of one is the highest, but this cannot be achieved a statistical population. It's sort of like the speed of light, it can only be approached but never reached.
it is the signal of something which can be something by being something that gives signal like some sort of phone??. yeah like that man, this is my letter to my crush...
sort of!
Light would reach it in 2.2 million years, but according to Einstein's relativity, a spaceship can only get close to the speed of light , but never reach it. At that sort of speed, due to time dilation , a spaceship would get there almost instantly, but it would take an almost infinite amount of energy. So a spaceship very very close to the speed of light could reach it in minutes, whereas on Earth 2.2 million years would have passed. Not only does time slow down, but mass increases and length contracts at relativistic velocities. So as an object approaches the speed of light, its mass becomes greater and greater, until eventually it begins pushing up towards the mass of a star. The amount of energy needed to push the mass higher becomes correspondingly greater. Another effect, however, is that as you approach the speed of light, your own escape velocity increases. Before you reach the speed of light you enter your own Schwarzchild radius, effectively pinching off from the rest of the universe as a black hole. So you can't even theoretically get "infinitely close" to the speed of light. There are limiting factors precluding it.

The train in 1870'swith the speed of 85 miles per hour
The Shutter Speed. If the shutter speed is positioned at 2000 you'll have a very quick exposure, this is best used if its very bright outside. If the shutter speed is at 75, you'll have a very long exposure, best used if its cloudy or dark.
