    Graduate How to derive t1 in terms of t and t in terms of t1

    1. (x=X1+vt1, x1=x-vt ) 2.(t=t1+vx1/c2, t1=t-vx/c2 ) I know that 1. is x in terms x1 and x1 in terms of x. I understand it very well, the adding and substracting of velocity. But i am unable to understand the 2.how these equation are derived and what does they mean. The mane...

    Graduate Why the black hole density is called the infinite density.

    d=m/v, d= density, m= mass, v= volume If volume is 0 than the density is infinite.But if black hole has radius it must has a volume.So how its density can be infinite.
