When speed becomes >>>> light, gravity becomes >>>> 0

Is it true?
My friend say...

I'm not really sure what you're getting towards, but I suspect the answer is no.

Relative Mass increases with Velocity, so as Velocity approaches c, mass approaches infinity (one reason why any object with mass cannot break the speed of light) though I don't think relative mass affect gravity, it certainly doesn't cancel it.

The easiest way to look at it, light (which travels at c is unable to escape a black hole, if gravity was zero for something travelling at c, this would not be true.
