NASA supercomputer finds billions of comets mimicking the Milky Way's shape: 'The universe seems to like spirals!

I need to help you all with the heating of the Earth's mass. Gravitational heating is basically two directions of which the effect of compaction of substances during the formation of the Earth can be considered negligible. I will return to the second heating effect related to gravity later. In principle, the fall of asteroids is part of the pulsating formation of the Earth. That's right, this is not a process that has an end. The main formation was completed after several stages, an initial accumulation of matter during which Gaia reached dimensions and mass not much different from today, but still not the same. Subsequently, a planet has collected more matter while cleaning its orbit and...here is one special event that brought a lot of energy that has heated Gaia significantly. This is the collision with Theia and the formation of the Earth and the Moon. This impact alone has heated the Earth as much, if not more, than all the energy that the planet has absorbed from solar radiation in the entire time since the Earth existed. Moreover, the Earth continues to be heated by the tidal gravitational effect with the other product of the collision between Gaia and Theia, namely the Moon. Incidentally, there is a significant tidal gravitational effect on the Earth from solar gravity as well...And finally there was the heating from the decay of radioactive elements.

I’ll bet the heat this planet generates is much more than known. If it were not for evaporation this planet would be too hot to live on. The only reason our crust and air is cool, is because of our ocean basins.

Just a personal supposition.

Evaporation cools the water, but where does that heat energy go? Into the atmosphere, right? So how is there going to be a net cooling effect?

 

[Classical Motion]

I would say the energy goes into a temperature, pressure, and density gradient around our planet. And eventually into space. With a hysteria effect.

Evaporation cools the crust too. I’m convinced our planet’s crust is saturated with water. Super heated water at depth. Anywhere. About 10 miles away.

Just another personal supposition. No expertise.

Either the hot core makes a significant thermal contribution to the habitability of the surface environment, or it does not.

The "habitability of the surface" was not critical to the issue. Habitability anywhere was the point, which would of course be inside the planet without an external heating source for surface.

The point was just that Earth is externally heated, and so does not serve as an example of this idea. I probably should have just stated it like that.

The initial point was about a "dark planet", and how it would behave. This dead horse has now been beaten enough I hope.
