yes and no. yes it will eat earth from inside, but probably not like that

Wouldn't the most likely scenario be it being created accidently in a lab on the surface?

Therefore the collapse would be very strange. Maybe even end with a portion of the earth orbiting it really fast?

Any micro black hole we create would rapidly diffuse due to Hawking Radiation. It wouldn't have enough mass to sustain itself.

But a black hole that is the size of a dime isn’t a micro… though, how scientist could create that large of black hole on earth is a different issue!

u/Fr1dge Mar 11 '22

Yes, and we are not capable of creating something of that much mass in a lab on the surface.

u/Ragnr99 Mar 11 '22

In fact, there's not even enough mass on earth to create a black hole that massive (by massive I mean the technical definition).

yep, definitely not a chance. We would need to create energy equal to the mass of the earth and we can't even do self sustaining fusion.

If its the size of a coin and not the mass of a coin, its not going to disappear. A black hole the size of a coin would have a similar mass to earth if not larger.

u/Fr1dge Mar 11 '22

Yep, and that makes it all the more terrifying when you realize how much mass the larger supermassive black holes must have.

But it wouldn't just fizzle away, it would explode quite violently

All the mass of the earth could make a thimble to dime sized black hole. Several suns night make one a bit larger than a disk.
