Do we see the universe now as it existed in the past?
True, since the speed of light is finite.
Is it light speed or the speed of light?
speed of light I think well it sounds right:)
Is it possible to travel at the speed of light in water?
The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
Is the speed of light or sound faster?
The speed of light is about 880 thousand timesfaster than the speed of sound.
Is the speed of sound as speed of light?
The speed of light is much greater than the speed of sound.
Is the speed of light greater or lesser in air than in water?
The speed is the same. Light travels at a finite speed.
Do we see the universe now as it existed in the past?
True, since the speed of light is finite.
How many image in 2 parallel mirrors?
It's not infinite, it's finite, because the speed of light is finite. Actually, when you look at one of these mirrors, the number of images will increase continuously at the velocity "c", so you can accept that its limit is infinite, but in other hand it's finite because the speed of light "c" is finite, it's a physical "optical" paradox.
How many images are seen when two mirrors are placed in parallel?
If they are back to back, only 1. ------------------------------------------------------ If they are face to face,it's not infinite, it's finite, because the speed of light is finite. Actually, when you look at one of these mirrors, the number of images will increase continuously at the velocity "c", so you can accept that its limit is infinite, but in other hand it's finite because the speed of light "c" is finite, it's a physical "optical" paradox.
How many new stars appear to the Earth each year?
Assuming you mean due to the finite speed of light, that is a very hard question.
What happens if you move at the speed of light?
You would have infinite mass and infinite length. From your perspective, you would get to your destination in zero time.If you have finite mass now, it would require infinite energy to attain the speed of light, so this can never happen.
This theory by Albert Einstein explains why all observers have their own separate measure of time because of the finite speed of light?
The theory of special relativity.
How many images do you see through a pair of parallel mirrors?
It's not infinite, it's finite, because the speed of light is finite. Actually, when you look at one of these mirrors, the number of images will increase continuously at the velocity "c", so you can accept that its limit is infinite, but in other hand it's finite because the speed of light "c" is finite, it's a physical "optical" paradox.
Can what you see really be what it is?
Light's speed is finite, so when you look out into space and see a star, you're seeing into the past, so it might have gone supernova or something.
What happens when you go the speed of light?
Short answer: As for today, we do not know for certain. It is by existing theory, Einstein's theory of relativity, impossible for matter (mass) to reach the speed of light.A little longer: By Theory of relativity, the energy which is required to reach the speed of light is a limit which stretch to infinity. As energy can't be created nor destroyed, there is a finite amount of energy in the universe, and the speed of light cannot be reached.
Is it possible to find information about past in universe?
Yes. That's what telescopes allow (and require) that you do. The reason is that the speed of light is finite, so you never see "now", but what happened in the past.
Is it the speed of light or light speed?
Is what the speed of light or light speed.ANSWER300,000 km/s
