I don't understand the law of relativity.?

Question

What the connection between Time and Mass?
Give me the example please...

And please keep it simple, but clear.

Answer 1

The center point of relativity is that the speed of light in a vacuum is a constant, no matter where you are and what you do, and that any viewpoint is just as valid as any other.

The consequences of this is that the perceived mass of an object moving at relativistic speed would have to change, and that the flow of time on that object would also be affected, from the perspective of an observer who saw the object accelerate.

In a particle accelerator, it is noted that subatomic particles which a known decay rate will decay slower while they travel at speed close to that of light; also their mass would be much higher.

As to your request to make it clear and simple, sorry this is the best I (and possibly anyone else) can make it. After all, it took an Einstein to come up with the theory, and that was not an overnight thing...

Answer 2

A simple connection between mass M of a particle or a body and time t is proposed. The flow of time t depends on the relative change of mass

Answer 3

A simple example of the relationship of time and mass would be the center (singularity) of a massive black hole in space. At the center, matter is collapsed and infinitely dense (such that the mass of a huge star could occupy the space of the period following this sentence!). As such, all the laws of physics as we know them break down including distortions of space and time. Light (still traveling at the speed of light) can not escape a black hole (that is why we see only a black hole in space). A body entering a black hole is torn apart by tidal forces and accelerates toward the center but never gets there because of the distortion of time. The black hole still exerts gravitational attraction to other heavenly bodies depending on its total mass. These effects exist throughout the Universe but are too subtle to be detected in most cases without sophisticated instruments. For example the path of light (from a star) passing close by our sun is bent due to the mass of the sun (helping to prove Einstein's theory of relativity). Hope that helps but your question goes to the heart of a very complex issue that perhaps very few (including me) thoroughly understand.

Answer 4

There are two different concepts you might consider. The first is found at http://360.yahoo.com/noddarc and is a short, easy to read writing entitled "The Twin Paradox". The second is that of the physics trilogy, which is: E = mc2, m = E/c2, and c2 = E/m. The last is that of a field of gravity, or of physical time - these two are the same value having different names. What we are interested in, though, are the first two equations. Notice that the basis of each is the "c2" value. In the first instance it is the multiplier and in the second the divider.

The value of "c2" itself in these equations describes the duration of physical existence. That existence is that of the speed of light. The reason this is true is that it is physical time that we, as our universe, are totally composed of. It is for this reason that all forms of energy and mass move from present time to that of becoming the past at the same rate of speed. The value of "c" (the exact, very precise speed of light, or electromagnetic energy) is the only value that objects in our universe are able to exist in. Were this value to change in either an up or down value, whatever was formed of that new value would no longer exist in our universe but would become part of another. That universe would also have an exact, precise value for "c2" and everything there would have to be composed of that value or cease to exist.

Perhaps this is an obscure manner of getting to your question but it forms the basis to understand why mass exists as it does, and what its meaning of existence is. Mass and physical time are the very same entity. Mass is composed of physical time "c". Once mass moves to the speed of light mass converts into electromagnetic radiation. At the above address there is also a short writing entitled "Concepts Concerning Time, Gravity, and Energy". I takes just a minute to go through it.

Answer 5

There is an indirect tie between time and mass. A clock in a grvitational field runs more slowly that one that's not. Pick up "Relativity for Dummies" .. I hear it's not too bad.
