I'm thinking that this is easy to test and find out.

When you blink, the only part of you that moves is your eyelid. The rest of you stays still.

So if you move your eyelid faster than the speed of light and it goes back in time,

then your eyelid would disappear, because the rest of you would stay here in the

present time.

You could try it any time, wherever you are, and see what happens.

But how fast would you have to blink ?

If your eyelid moves a whole inch during a blink, then in order to move at the speed

of light, you'd have to move it fast enough to blink 11,802,827,520 times in one second.

That's about 590 thousand times faster than that high squeal you hear from

a mosquito's wings.

Do you think you can do that ? Good luck on your experiment.

Can you go faster than he speed of light?

According to our current understanding of physics, it is impossible for any object with mass to travel faster than the speed of light in a vacuum, which is about 299,792 kilometers per second. This limit is a fundamental principle in the theory of relativity proposed by Albert Einstein.


If you travel the speed of light will you age slower?

As you go faster and faster, time appears to slow down. If you could go 99.99999% of the speed of light, you would hardly age at all in 100 years. According to our current understanding of physics (and this is subject to change!) you can never move AT the speed of light, although with enough power you could approach it very nearly. The faster you go, the more time slows down.


What happens if you are going the speed of light?

No particle can exceed the speed of light in a vacuum. Only massless particles can travel at the speed of light because as speed increases, the mass of the particle also increases, and the amount of energy it takes to accelerate it increases. As a particle (with mass) approaches the speed of light, the amount of energy needed to accelerate it approaches infinity. There is one exception to the speed limit of the speed of light and that is the speed of a particle moving through a material medium. (For instance, glass has an index of refraction of about 1.5 which tells us that light moves through glass at a speed that is about 66% of its speed in a vacuum.) High energy particles can move through materials faster than light can move through the material. When that occurs, there is an interesting phenomenon called Cherenkov radiation. This radiation is simply light, but it results when any charged particle moves through a medium faster than light move through the same medium. (See related links.)


How do you understand the speed of light in human terms?

The speed of light is so incredibly fast that it is difficult to express it in human terms. But here are some comparisons. If you could run at the speed of light, you would be able to run around the world seven times in a single second. If you could run at the speed of light, you could run from one time zone to another in the blink of an eye. You would be able to see ten sunsets in the same evening! When you are talking on an international phone call, you can say something on the phone. Your call will go up into space to a communications satellite 23,000 miles into space, and back down. And you hardly notice the delay!


Which is faster the speed of light or the speed of soundd?

Electricity. Sound, whether in air, water or a solid such as steel, is a compression wave that moves atoms back and forth. It is slow. In air, the speed of sound is 343 meters per second (1,126 ft/s), or 1,236 kilometers per hour (768 mph). It takes 3 seconds to travel one kilometer or 5 seconds to travel one mile. It is 4 times faster than that in water and almost 15 times faster in iron. Electricity involves the motion of electrons, very small and light with a significant long range Coulomb force between them. Electricity can be pictured as moving electrons which push against their neighboring electrons that in turn push against more distant neighboring electrons and this all continues for distances much much greater than the region occupied by a single electron. In some ways, this propagation by pushing against the neighbors is basically similar for both electricity and sound. But, for electricity the masses of the moving electrons are much much smaller than the masses of atoms and forces on electrons are longer ranged and strong. Electrical disturbances on a conductor travel at almost the speed of light, but depends on the geometry of the conductor. For normal wires and normal electrical current such as used by people in everyday life, the speed can be over 95% of the speed of light. The speed of light is 300,000 kilometers per second. For other arrangements of conductors (waveguides) it can be much slower and a speed of 200,000 kilometers per second would not be surprising. One is not far off if one says that the speed of light is 1 million times faster than the speed of sound.

What is faster the speed of light or the blink of a human eye?

Let's say that you can accomplish a complete blink in one hundredth (0.01) of a second. In that amount of time, a beam of light could travel . . . -- from New York City to Albuquerque, New Mexico, -- or from Los Angeles to Grand Rapids, Michigan -- or from London to Rome and back to London -- or from Jerusalem to Berlin -- or from Miami to Disney World and back to Miami, almost five times.


Why does your front signal light blink faster than the other?

Check the back signal light. Usually if the front blinks fast the back is out or need to be replace. Vice versa


How can you go back to the past?

Easy....travel faster than the speed of light...


Does the earth age faster if you went to Pluto and back going light speed?

No


Why shouldn't you blink?

Don't blink. Blink and you're dead. They are fast. Faster than you can believe. Don't turn your back. Don't look away. And don't blink. Good Luck.


How fast would you have to travel to go back in time?

Faster than the speed of light, in theory.


Can a person go back in time?

yes a person can go back in time if they go faster than the speed of light. better start training!


If you could travel speeds greater then the speed of light would you be able to travel back in time?

Yes and No. Yes because traveling faster than light would make you go back in time. No because you would need an infinite amount of energy to go at the speed of light according to Einstein Also going at the speed of light or faster you would tern into light. So "you" could not go at the speed of light but light could. Time travel is possible but only at the earths gravitational pull (Turn) if the earth went backwards in spinning, but at the speed of light, the earth would move backwards through time as it broke the atmospheric compression field. WELL, AS IT HAPPENS... On a Distance against Time graph, the more distance you travel in the same amount of time, the steeper the line and therefore the faster your speed. The speed of light on such a graph is VERY steep, but it is NOT vertical. If it was a vertical line, then you would be travelling INFINITELY far distances in zero seconds. Which is impossible. However, assuming that it isn't, going EVEN FASTER would mean the line would start to curve back on itself, which would mean you were travelling a certain distance in a certain number of NEGATIVE seconds. Which would mean you were travelling back in time. So to answer your question, going faster than the speed of light would result in a VERY high speed. However, to go back in time you would need to go faster than a vertical line on a distance against time graph. In other words, to go back in time you would need to go FASTER THAN AN INFINITE SPEED. So, no you couldn't travel back in time by going faster than the speed of light. Even if you could, which you can't.


If something started out already traveling away from us at greater than the speed of light will its light ever reach earth?

No. Speed of light is constant in all frames of reference, even if you are also traveling at the speed of light, the photon will speed away from you at the speed of light. When you see an object, what is happening is that photons are reflected off the object you are looking at and bounce back into your eye. However, if you are traveling faster than the speed of light, the photons can never reach you to start with, hence, you are invisible until your speed decreases to something below the speed of light. It is possible to travel faster than light in many ways. First, if you have a negative amount of energy, you will always travel faster than a speed of light. Another possible way is to compress the space in front of you, then move to your destination before re-expanding the space you have just past.


If you were aboard a supersonic jet which direction would you head to go back in time?

First of all, you have to travel faster than the speed of light, not sound, to go back in time. No aircraft can go that fast, or any other vehicle for that matter. At least, not yet. Second, it doesn't matter which way you're pointing, you just have to go faster than the speed of light.


Is time travel possible or not and elaborate on your answer?

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


If you were to travel faster then the speed of light then stop and turn to look back would you see yourself running at you or away from you?

It depends on when you look back. Whether you look back while running or stop, rest and then look back makes a difference.
