How come V is a constant in E=Mc2 over V, but time is a variable without dimensional drag?

Ah, right, yeah v is for velocity but V represents anti-gravitational waves,
you know!
from Einstein's equation for gravitational expressions in General Relativity.
V = the square root of 1 - v2 over c2

It is impossible to measure instantaneaous velocity. Therefore measurement can only be taken as average.
The average value is than considered constant.

I suspect you've been given duff information.
'c' IS a constant, the speed of light. If V were a constant then c/V would also be a constant represented by a different symbol.
V is NOT a constant. It is the way of representing the Tau factor without resorting to Greek symbols. The Tau factor is directly related to V(elocity) relative to the speed of light. Thus as velocity increases, the Tau factor increases. The result is that time slows down for the travelling object (hence time DOES suffer from dimensional drag) and the Lorentz-Fitzgerald contraction comes into operation shortening an object moving at relatavistic speeds. At the same time a higher Tau factor increases mass proportionately.
A solid object travelling at the speed of light would have zero length, infinite mass and would not experience the passage of time.
Is That sufficiently clear?

in Physics, v (Not V), is velocity. The velocity in this question is the speed of light (c), which is always constant ant 300,000 km/s.
The speed of light is refered to as 'c' because is is always the same.
If you have E=(mc^2)/c, the 2 c's would cancel out and leave E=mc (jokes about Hammertime, lol)
V in maths stands for Variable, which is the variable figure in a parabollic problem, so is not constant, but thats maths.

Cos that's a theory of Einstein, that the highest speed in the universe is the speed of light and so the formula is true for the only possible highest speed 300,000 kilometers per second roughly.

I'm guessing that if you cannot use proper grammar in a simple sentence, then the actual answer to this advanced physics problem is going to be a bit above you.

Now I am going to have to post a question "What is dimensional drag?" Damn,foiled again!

I dont know , i think it might be the time of night, 12:53am , but I dont undestand the question .

how do you know if a letter is a constant or a vowel anyway?

It's consonant not constant

Because V isn't a vowel! LOL!
