Lets calculate with some known "facts". They say that there are 10^24 visible stars in the universe.
Our sun is a medium sized star and has a mass of 2x 10^30 Kg. Let's assume that this is the average mass.
The speed of light is 3x 10^8
Therefore the energy in joules, or watt seconds, to make the visible universe is in the order of 1x10^24 x 2x10^30x3x10^8x3x10^8 = 18x 10^70 joules
It is said by some physicists that visible matter account for only about 4% of the matter in the physical universe.
Therefore, the figure for energy now is multiplied by 25= 4.5x 10^72 joules
(Some mathematicians might consider the smaller number 10^65 to be infinity for all practical purposes)
If we divide the above figure by 5x 10^9 , this will result in the number of tons of TNT equivalent, which is roughly 1x 10^63 Tonnes of TNT.
This figure is so large it is really above our comprehension.
If you now consider that some say that the universe was (kind of) made in 10-43 seconds, then the power required to unleash that sort of energy, from the formula
Power= energy divided by time, then the power required is 4.5 x 10^72joules divided by 10^-43 which is 4.5 x 10^115 watts
Elementary, my dear Watson...
