First-off, I know there have been multiple attempts on explaining Supes on various books and websites and I haven’t read any of them. And so, if there has been an explanation similar to mine, I bet it would be much more intricate and so it would be best to link the reader there. I know physics is not my major so I am pretty sure I’ll be corrected one way or another.

Anyway’s here’s my take on Supes. A lot of people say that, in a way, Supes is a somewhat “perfected” being. He also is claimed to be a very effective battery. And with this premise, we’ll try to explain how much energy Supes can dish out.

Being a “perfect” battery, at best he should be able to have a perfect mass-energy equivalence. What is this equivalence? Einstein’s E=mc^2… Or Energy is equal to the mass and the square of the speed of light in vacuum.

We apply this equation to Supes with a stated weight of 225 lbs or 102 kg.

E = mc^2

E = 102 kg * (299, 792, 458 m/s)^2

E = 9,167,302,823,115,539,928 Joules = 9.167 Quintillion Joules = 9.167 Exajoules

In comparison to the Hiroshima bomb which had the energy output of  5.4 TJ, it can be observed that Supes, at best, is 1,685,185 times stronger than the first A-Bomb Little Boy.

Also in comparison to the Tsar Bomba (H-Bomb) that had an energy output of 210 PJ, Supes is 4,333 stronger than the strongest bomb explosion in history.

Now this is where things go iffy with comics and science. Superman was meant to move at least a third of the earth’s weight. But doing so is impossible. The force needed to move the earth for a speed of 60km/hr is 5.974 * 10 ^27 Newtons. Meaning to just move the earth a meter from its current position, one needs 5.974 * 10 ^ 27 Joules. That’s around 5.3 * 10^8 times more than what we have computed for Supes.

Yeah, all of this is pointless. Real-world physics does not equate to comics anyway so meh… I just wanted to show what’s on my mind… :D
