TIME SLOWS DOWN WEN U TRAVEL AT D SPEED OF LIGHT, only if our physical age does not increase, then its true ?

Question

einstein said in his theory of relitivity that time slows down if we travell at the speed of light, THE QUESTION WHICH COMES TO MY MIND IS.... its only acceptible if our physical age also slows down and when we travel at the speed of light spending one year in outer space then our physical age should aslo increase one year only, other wise YOU MAY SAY , only your clock slows down at the speed of light ... WHAT DO YOU SAY ?

Answer 1

Theoretically speaking, if one were able to, for example, leave the earth on some rocket which would travel at the speed of light (or very close to it) in some big loop and come back to earth, the people on the rocket, upon returning to earth, would not have aged as much as those who stayed behind. So, relative to the clocks on earth, the clock on the rocket would be slower, and, relative to the people on earth, the ones on the rocket would age slower. However, to the people on the rocket the passage of time would seem normal. This scenario can be loosely explained using only special relativity (without resorting to general relativity). In special relativity, the observer, and the object being observed are both in inertial frames of reference (neither is accelerating), while in general relativity this need not be true. Since the rocket has to somehow accelerate to the speed of light, one actually needs general relativity to treat the problem quantitatively, but for a qualitative explanation special relativity is sufficient.

Experiments have actually been conducted on particles that tend to decay into other more primitive particles in fairly short amounts of time when simply observed at low speeds. It has been found, in accordance with the principles of relativity, that when these particles are accelerated to speeds that near that of light, they take longer to decay (i.e. to the experimenter it appears that the particle's clocks have slowed down). The logical progression is then that if one were able to accelerate a system of particles (like a rocket full of people) to near the speed of light, the rocket and the people in it would age (decay) more slowly since their clock would slow down just like it did for the particle in the experiments. The problem, of course, is that a rocket weighs much more than a single particle, so it will take a lot more energy (more than we can pack on a rocket right now) to accelerate it to speeds high enough for relativistic effects to become significant.

Answer 2

If your clocked slowed down, then your 'internal clock' would slow down too, because the clock slowing is not of a function of the clock it is a function of time being slowed which would affect you, the clock and everything else that is travelling at the speed of light.
This is a generally accepted principle of The Theory of Relativity.
The big thing is: How does one reach, or even approach the speed of light? The faster you go, the greater your mass becomes, that is another principle of E=Mc2. Matter cant go that fast and still be matter. You would be converted to energy which could be messy.
We are a long way from having the ability to accelerate ourselves to near the speed of light.

Answer 3

If you were traveling at the speed of light, time would never change. An example I have seen used is a man that looks at a bell tower clock is launched at the speed of light and since the light bouncing off the clock is traveling the same speed as he, time would stand still on the clock. But if he traveled half the speed of light he would see it half as fast as he normally would, letting him age twice as slow. Technically, gaining speeds of this is nearly impossible because as an object moves close to speeds near that of the speed of light, its mass actually increases to the point where a force capable of moving it would not be viable.

Answer 4

It doesn't work that way... every thing in the universe has a relative "time clock" we live a full life in about 80 years or so. A dog in 8 yrs or so. a fly 48 hrs and so on. But that is according to the TIME that WE created; to a fly they have lived 80 years in 48 hrs!
The concept of moving through time is just that. You remain the same, but you are able to travel through several strings of time without aging. When you fly around the world in reverse of the rotation you are in fact reversing time.( time as "we" record it).
Our body's stop working when they are ready Time is something we created.
SO! it is TIME we are speeding and slowing not our physical self.

Answer 5

What needs to be determined is, why there is a time distortion due to moving toward the speed of light. The answer has to do with the composition of mass. What is it in moving mass that changes due to acceleration?

The physics trilogy explains why there is a time dilation due to movement. The trilogy says: E = mc2, m = E/c2, and c2 = E/m. Notice in each of these thoughts that the basis of each is the "c2" value. This is the only value, "c", that cannot change. Both mass and energy are values that are not constant. These values are interchangeable. When considering physical time, we find that mass and energy, according to the above equations, are composed of the value of "c2", or of physical time. It is for this reason that our universe has all energy and mass values move from the present to the past at exactly the same rate - that of physical time of which they are composed.

Lastly, when a person accelerates, they are subject to a frequency change within their mass that is the same as that of electromagnetic energy. Zero mass acceleration allows energy within a mass to move in all directions at the speed of light. Were a mass to accelerate to a speed of within 2 mps that of the speed of light, mass at right angles to direction of travel would be at most that of 2 mps. What happens is that the total frequency of the mass converts so that the energy moves at right angles to that of the direction of movement.

Answer 6

Einstein did not say this.

Einstein said that clocks in different reference frames run at different rates RELATIVE to one another if they are moving.

Time for YOU always passes at exactly the same rate, regardless of your speed. The rate you see time pass for SOMEONE ELSE who is moving with respect to YOU will not be the same. However, time for them will pass at exactly the rate they expect.

Its just that time is not absolute, its relative.
