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.

∙ 13y agoSeveral things happen as an object moves at higher speeds. One is that the object traveling near the speed of light experiences time differently, and everything else will appear sped up. A person traveling near the speed of light will age more slowly than someone standing still. It is impossible for anything other than light to actually travel at the speed of light. In reality, though imperceptible from our perspective, any acceleration will result in experiencing time more slowly.

∙ 10y agoIt's impossible to travel at the speed of light. But you don't have to !
Whenever you move, no matter what speed, you age slower. And the
faster you move, the slower you age.

According to the Theory of Relativity the closer an object gets to the speed of light the slower it goes so why does light which travels at the speed of light travel at all?
AnswerThe question states an incorrect premise. As an object approaches the speed of light, neither the object nor light "goes slower". At relativistic speeds (speeds of about 1/100 of the speed of light or faster), the faster a body travels, the slower time passes for that body compared to a "non-moving" frame of reference.Light is measured to travel at the same speed for all observers, no matter what the observer's speed is. For example, suppose you were in a space ship traveling at 1/2 the speed of light, and that space ship was racing toward a star. You would measure the light coming from that star at c, the constant speed of light. Now suppose your friend was in another space ship which was "stopped". Your friend would measure the same light coming from the same star at the same speed of c. The difference between you and your friend is your friend would age more quickly than you would, because time passes more slowly for you while you are traveling at relativistic speeds.It is also true that, as a body approaches the speed of light, it develops something called relativistic mass. So you, your space ship, and everything in it gets heavier when you travel at 1/2 c. Because the space ship gets heavier, it becomes harder to push (it has greater inertia), and therefore it is more difficult to accelerate the space ship further to make it go even faster. So it is true that, as you approach the speed of light, the harder it is to approach the speed of light. The mathematics predicts that, at the speed of light itself, your relativistic mass is infinite1, and so is your inertia, therefore you can never "push" something to make it actually go as fast as the speed of light.Light itself is a bit of an enigma. A photon - a light particle - has zero mass, but it does have momentum. Zero mass also means zero relativistic mass, allowing the photon to travel at c. In fact, not only can a photon travel at the speed of light, it must travel at the speed of light - a photon exists only while travelling at the speed of light - it ceases to exist if it stops or slows down.1 Relativistic Mass = Rest Mass / SQRT ( 1 - v2/c2), v is the velocity and c is the speed of light.Answer:I think I know where this question is coming from, but you made a bit of a confusion perhaps? Basically, the closer you get to the speed of light, the slower time goes? Is that what you meant to say? Relativity is very hard to get your head around, because you need to drop the concept of velocity altogether, and only think of relative velocity, and time, and even length in the direction you travel in (I did say it would be weird!). Light will ALWAYS overtake you at 300000000m/s. It doesn't matter how fast you go, or how slow you go relative to the source of that light, it will always, if travelling through a vacuum, travel at the speed of light given, and this value is a constant value called C. Its the space speed limit that is policed by the laws of physics. But, if you did travel very fast (close to C), there would be a time dilation relative to people here on earth. And this was first discovererd when they realized that particles that came down to earth from the upper atmosphere had a half life such that they should have decayed before they made it to the ground, however, because their velocity relative to the earth approaches C, they actually lasted longer! This same principal would apply to humans, so it would be possible to sit in a space craft, go close to C, come out 1 year later, and for all your friends and family and everyone you know to have grown old, whilst you'd only be 1 year older, because more time would have passed on earth than would have passed in your space craft, and this is called the time dilation effect.
If time stops at the speed of light shouldn't it be everywhere at once?
If you mean, shouldn't light be everywhere at once... then no. Time only slows down for matter traveling close to the speed of light. And by 'slows down', I mean it's only slower to stationary observers watching the speeding matter. To the speeding matter everything is business as usual, but the universe looks a little different. You start to notice things like time dilation (the universe around you seems to speed up) and space flattening (the amount of space you travel through to get places seems much less). So, to answer your initial question, to a stationary observer, what's going on in a light ray may seem stopped, but the speed the light ray is traveling is measurable. The cool thing about this is, since time is stopped for the photon compared to the rest of us, they never age. That's how we can observe the light from galaxies that are 10 billion light years away.
An electric field travels over a wire at what speed?
almost the speed of light which is 300 000 kmps i am not sure of an exact figure but i know its close to light speed also the amp-age on the circuit can affect it
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 did the Greeks measure the speed of light?
I don't believe there was any serious attempt to measure the speed of light before Galileo. That was a couple of millennia after the golden age of the Greek philosopher 'scientists', who, I believe, assumed the transfer of light to be instantaneous, and the perception of distant events to be simultaneous with the event.
How old would you be on mars if you?
The same age you are now. Unless spacetravel occurs then the speed of movement would reduce the amount aging based on space-time. The closer you get to the speed of light, relative to others who are not near the speed of light you will age slower.

Why do you age more when you approach the speed of light?
Actually you would age slower. Time passes more slowly at higher speeds. For a detailed explanation (how this result is derived), read an article about the Special Theory of Relativity - however, it is based on the basic assumption that the speed of light is constant. This strange fact - that the speed of light (in a vacuum) is constant - has been confirmed by countless experiments.
Why does your age decrease as you get further from the sun?
It doesn't. You're thinking of a result of relativity which states that the faster an object moves, the slower its clock runs. If you or I were to travel at 99% the speed of light (0.99c), our clocks would run very slow, and we would age at a very slow rate, because everything is taking longer for us.
If you travel at speed of light to another planet will people age more than you when you get back?
According to Einstein's theory of special relativity, this is correct. His theory states that relative velocities correspond to differences in time. In simple terms, a "faster" moving object's clock will tick slower than a stationary object's clock. Thus, if one were traveling at close to light speed (one cannot travel exactly at light speed) to another planet, upon his return he will have aged less than those people who remained stationary, with respect to his motion.
Is it possible to travel back to the past if we travel at the speed of light?
Yes, it is possible for sub-atomic particles to travel faster than the speed of light (186,000 miles/second). A total of 15,000 neutrino beams were fired from Geneva, Switzerland --> Gran Sasso, Italy and were found to arrive about 60 nanoseconds faster than light would have. "It is a tiny difference," one scientist was quoted as saying, "But conceptually it's incredibly important." For more information on breaking the speed-of-light barrier, please see the article attached below.

Is it possible to be multiple ages?
nope, yiu can only be one age at a time. but you can age slower than someone if you are moving at a ridiculously fast speed, like .99 the speed of light, than you will age about 1 day in ten years, yet you will still have the life expectancy, so you can die as an eighty year old baby, looking only eight days old.
How does the speed of a river determine what type of material the river carries?
The speed of a river determines on the age of the river. The younger the river the faster and stronger the river is, the older the river the slower and weaker the river is.
