If 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.
Comment on What would happen if the Earth was sucked into a black hole?

Depends on how big the black hole is. Small, and we’ll be ripped to shreds before the event horizon. Big and we’ll be immortalized in an ever-shrinking amount of red shifting photons from the external perspective. From an internal perspective we’ll also be ripped to shreds tho.

How explosive is the explosion of 1kg black hole?
MojoMcJojo@lemmy.world 2 days ago
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.
TheLeadenSea@sh.itjust.works 2 days ago
So would it have a similar effect to a radiation bomb, but without the radioactive fallout?
TranquilTurbulence@lemmy.zip 2 days ago
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.

I’d actually guess that we’d end up in an accretion disc first and would be ripped to shreds there due to all the other stuff in orbit and less from direct influence from the black hole itself.
Lasherz12@lemmy.world 2 days ago
If it’s rotating, yes. All real black holes are, so you’ve got a point. The tidal force ripping happens in the accretion disk regardless, though. The spaghetti just forms nearly perpendicular to the hole instead of directly towards it.

If it’s very large and stationary, we could survive, couldn’t we?
Lasherz12@lemmy.world 2 days ago
From my understanding, no. The center of a black hole is theorized to be smaller than the planck length at at least one “pinch” point. I believe you’re mistaking surviving the event horizon with surviving the entire journey to the splat zone. You’ll still be spaghett before the center. It’d be like hitting an impenetrable wall at the speed of light and coming to a complete stop, you’d more like a bunch of neutrinos by the time you get there I think.
rikudou@lemmings.world 1 day ago
Yeah, I didn’t mean surviving reaching the center. But on the other hand, a singularity cannot exist (as far as we know), so what’s going on inside the black hole is one big unknown.
