Does relativity theory indicate that celestial masses inrease with time and decrease with increased velocity?

Answer 1

Instead of asking question after question, you may want to do some actual reading on the subject, since you seem to be curious enough about it.

For the definitive text on relativity, you can try Einstein's text itself. It's archived in project Gutenberg:

You can also try a text more suited for the layman, such as The Elegant Universe or A Brief History of Time.

Answer 2

The Theory of Relativity, E=MC2 is Energy = Mass x Speed of Light Squared.
Basically it boils down to the following. The closer a person approaches the speed of light, the more Energy is required to move that mass. Time is Relative, because at the speed of light, what might seem like 1 year, could actually be 4 or 5.
A scientist once said it this way. "Imagine you are travelling to Alpha Centauri (The Nearest Star at 3 light years distance.) If you attempt to travel the speed of light, it might seem as if you are travelling slower, and a 6 year round trip might take 100 years."

Answer 3

The Theory of Relativity indicates that with increased velocity, mass increases and time decreases...RELATIVE to someone observing from a fixed point in space-time. By the term "celestial masses", I hope you mean particles, not planets.

Answer 4

hmm not as far as I know, if anything, mass increases with increasing velocity., but the effects of relativity dont really come into play unless you are going at least 5-10% of the speed of light.

Answer 5

sorry i didn't understand your suggesting of increasing mass with time, in fact the word 'time' is not applicable here.
according to theory of relativity, as you must be knowing that
speed of light is concluding and at the zenith. accordingly when an object approaches the speed of light, its velocity has to reduce to prove the theory right. henceforth its mass starts increasing to stabilise, after which starts the density.
in other words you can say that mass increases with increase in speed. [ of course in comparison with that of light]
