CMBR is an electromagnetic radiation that are the the oldest remains of the big bang explosion. With the continuous expansion of the universe after the explosion, this radiations ere constantly spreading in all the direction for the last 13.5 billion years approximately.

fgravity=10x10=100n case 1

fgravity=30x20=600n case 2

6 times more

its a 5.5 n

glad that
