Homework Statement
Question number 1:
I have read in my textbook that absolute potential energy is
U= - Gmm/R
Now , my question is that if two bodies/particles are at a distance of 0.00008m or very close to each other so that the distance between them is nearly equal to zero , we will nee infinite amount if energy to separate them .
thus , U=∞
so how could particles at big bang separated then?
Question number 2:
In our textbook , I have read that 80% of the mass of our universe comprises of Plasma , While surfing internet , I have read that 80% comprise of black matter.
My question is how black matter and plasma are interrelated?
Waiting for answers , thanks
