how is traveling light speed related to time?

Question

Leaving the Earth at the speed of Light and returning in the future doesn't seem to make sense at all.

How would traveling at the speed of light and leaving earth,and returning Be any Different than going 100 miles an hour, and returning.

If Time did appear to pass Slower, Whether or not thats true. It would not change whether time HAS passed slower or not.just because something Appears a way to you, Does not make it So. how do those Two ideas connect!?

why would traveling in the Direction of the Waves make you experience less waves? if they waves keep coming like they should, you should still feel the same amount. Unless you are going as fast as the wave, then you'd feel nothing. But that doesn't Change Time in any fashion. You speak as though Speed has the ability to Alter Time.

If they are producing lower energy particles and that makes them not last as long...i don't think thats related to time, but more so related to a particle with a shorter life span. Thats like saying a test tube grown baby, doesn't live as long, so it travels through time faster.

Answer 1

according to einstein, time is an element of the universe, just like space, and it is not absolute. he further explains that as one travels near the speeds of light, time becomes slower, that is relative to a stationary observer. the traveller still observes his time to be normal but the stationary observer "sees" the time of the traveller to be delayed, that is slower... as predicted by lorentz transformation...

t' = t / sqrt(1- v^2 / c^2)

as the velocity nears the speed of light, time becomes more delayed. this phenomenon is observable in experiments in particle physics. particles produced by particle accelerators have a shorter life span than those produced by cosmic rays or those that come from space. this is because, the particles produced in particle accelerators have lower energies, thus they move slower and their time is "faster" relative to the more energetic particles created by cosmic rays.

Answer 2

Because there is nothing special about 100 mph or 200 mph or 1000 mph. Nature, if you want to call it that, has dictated that there is a maximum speed and that speed is the speed of light. But for material objects such as you or me or your car it is an upper limit. We can approach that speed but never actually reach it. Now why is this so? No one can answer that. It is an observed fact about the universe we live in. But because of this fact there are a lot of phenomena that occur as you approach the speed of light that are totally outside our day to day world and which don't seem to make sense. One is if I am in a car going 50 mph and you are approaching me in another car and likewise going 50 mph then, relative to me, I would say you are approaching me at 100 mph. And you would say the same about me. But this is not true. Velocities do not simply add as we think they do based on our everyday experience. If these cars were each going at half the speed of light and I used a laser speed detector to measure your speed relative to me it would not be the speed of light, it would be less than that (I would measure only 4/5 the speed of light). It is only because we can only move at very tiny speeds compared to the speed of light that straight velocity addition appears to be true. If you do some research you will find that these things have been proven in many many experiments.

Yes the person could come back 1000 years in the future and only have aged a year. Such things are possible. They have done experiments with atomic clocks on planes and things and found that the one sent off on a plane, when it returns will be slower than a clock left behind (atomic clocks are very accurate). This result is not intuitive in that it is outside our normal experience. The same with quantum effects. They seem bizarre because we exist on a scale that is vastly greater than that over which quantum effects are common place. But there are experiments that can be done to show these effects.

Check out the source. It shows what traveling near the speed of light is like plus it has some good explanations of all the effects. The second source shows how the theory of relativity effects the addition of velocities.

Answer 3

as you aproch the speed of light you age slower. wired things begin to happen to your matter as you aproch these speeds. picture this, there are waves in water and you are sitting there on an intertube. the waves are flowing left to right. you sit stationary, you will feel 10 waves a second. if you move in the direction of those waves you will expierence 5 or so. you expieiecen less as others expieience more.

So your friend in the intertube would say, man ten waves (years, minutes, etc.) passed. you would say no it was 5.

Answer 4

I don't pretend to completely understand it all but supposedly when you travel at the speed of light time slows down. But since it's impossible to travel that fast I don't what practical use anybody could make of that theory.

Answer 5

It does not slow time. You would feel normal, but you would actually by in a slow animation, while everyone else is aging normally. You would be the same age as everyone else. Time is intagible and cannot be manipulated. Some ignorant scientists did a test on atoms using an atomic clock that showed slowing. But this is obviously incorrect, as you cannot test time with time itself. Time isnt linear as we like to think of it. It is basically a way of creating a sense of linear aging. This of course rules out any time traveling, because there is no past or future to go to....only now.

Answer 6

We cannot time travel and I doubt if we can light speed travel.
