A sphere with a diameter of 1km and a temperature of 14 million kelvin gently drops into earth's ocean.

What happens next?

something like that doesn't "gently" do anything on an earth-scale.

It would have to be super massive. I imagine all of Earth and the atmosphere would almost instantly be gravitied into a thin layer on the objects surface. Then the rest of the solar system would go all wacky.

What's it made of? yes, it matters.

>> No.3026325

mass, velocity, electromagnetic properties.
All of these please.

there'd be no ocean before it dropped into the "ocean"

Uh, no. Nothing that is 1km in diameter will beat the Earth's gravity. Unless you're talking about black holes, I suppose. Neutron stars generally are at least 10 km radius.

Is it producing this heat or will it cool off according to Newton's law of cooling?

>> No.3026376

>>3026369

I am interested in both scenarios, actually.

>> No.3026378

It explodes violently because of its extreme temperature turning it to plasma, obliterating the nearest few hundred miles with the force of the blast, the amount of oxygen consumed by all the flames cause mass suffocation world wide

?
Yes, yes it does. Objects whose size is determined by their self-gravity definitely have this relation.

It will melt through earth and drop into space on the other side.

If it retains it's heat, it will likely produce a thick, massive, extremely hot, continuous boundary layer of dissociated monoatomic hydrogen and oxygen (and regular superheated steam at the outer layers), thermally decomposed by the extreme heat. This vapor will be pushed upwards by the weight/buoyancy of the surrounding ocean, and more water will continue to be consumed until the ocean's water level falls below the bottom of the ball (or dries up completely, presuming the ball continually sinks into the water). Just about everything in proximity to the ball will be vaporized by the extreme heat. The ball very well could melt it's way through the Earth's crust, given time which would cause who-knows-what to happen).
Now, the vapor boundary layer would reduce direct contact and thermal conduction, but the massive radiation flux from a 14x10^6 K body would be massive enough on its own.

For the other case, the above would happen until the ball cooled to more typical temperatures. Where the terrifying destruction stops depends on the object's net heat capacity.
