Infinite Mass, Infinite Energy

[WhyIsItSo]

There was an important question I asked that got overlooked.

With the increase of mass due to velocity, what is happening to density? Is the volume of the object increasing also?

Is the volume of the object increasing also?

Remember length contraction? It applies in the direction parallel to the direction of motion, but the directions perpendicular to the motion are unaffected. So the volume of the object decreases.

Huh...thinking...thinking...

mass increasing + volume decreasing = density increasing?

Or is this one of those points were relativity surprises me once again?
