Comment on What would happen if the Earth was sucked into a black hole?
TranquilTurbulence@lemmy.zip 2 days agoIf you press the universal terminal button, type in the command for spawning a black hole, set the mass to 1 kg, you get something very spicy. It’s so small, that it evaporates pretty much instantly, which means that all of that energy gets released as hawking radiation and the end result resembles an explosion.

How explosive is the explosion of 1kg black hole?

A lot Please, please, please, someone check my googled physics and AI math:
E = mc² = 1 kg × (3×10⁸ m/s)² = 9×10¹⁶ joules (90,000,000,000,000,000 joules)
or
~21.5 MEGAtons of TNT (by comparison, the Hiroshima bomb was ~15 KILOtons)
It would have a temperature of ~1.2 × 10²³ K (1,200,000,000,000,000,000,000,000 Kelvin) The sun is a 5,772 Kelvin.
Like a ‘small’ star, it would radiate energy of about ∼3.6×10³² Watts (3,600,000,000,000,000,000,000,000,000,000,000 W) The sun puts out about 3.8x10²⁶ Watts (380,000,000,000,000,000,000,000,000 W)
Final burst duration: less than ∼8×10⁻¹⁷ seconds, or slightly faster than it takes for your mom to drop her panties.
Now for the best part. All of that energy would emanate from a very, and I can’t express this enough, very tiny spot, like a billion times smaller than a proton:
~1.5×10⁻²⁷ meters
A proton is about 10⁻¹⁵
From seemingly nowhere, instant God-boom. I like to imagine that whatever was next to it would just disappear, and then the shockwave would happen.
Again, I googled and used AI to run the code for the calculations, so…you know, correct me and downvote.

So it would resemble the beginning of the universe, but smaller. Neat.

So would it have a similar effect to a radiation bomb, but without the radioactive fallout?

No one mention this to the US military

E=mc^2 should cover it, proper physicists can give you a better answer. Either way, it’s a big boom. Wolfram says, it’s about 90 PJ, which is firmly in the nuclear weapons territory.
