Someone had mentioned, "Although the atom bomb is probably something humans never should have developed,

the splitting of the U235 atom and the energy it created attest to Gods marvelous power.

Simply amazing. What must be the true magnitude of God power and light. Truly the light that no man approacheth."

The reply that came, was:

The first bomb dropped on Hiroshima was a uranium bomb and the one on Nagasaki was a plutonium bomb.

Uranium is named for heaven & plutonium is named for hell.

   Greek for heaven   οὐρανός   

   Pluto is the Roman name for the Greek god Hades, ruler of the underworld (hell)

It's like a foretaste of what's coming in the future:

    Luke 21:26 Men’s hearts failing them for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken.

(the powers of heaven)
