Lord Kelvin back in the 19th Century showed that the Earth would have radiated all its original heat from formation long ago. He therefore concluded that there must be nuclear processes occurring in the core which keep Earth's interior warm (who said nuclear energy was bad). When these processes stop, the Earth will cool down. I don't know (who does) but I expect that this will happen long before our sun's fuel is spent, although there's no need to worry - it won't be any time soon.
Incidentally, it is extraordinary to think that we actually know remarkably little about the processes occurring in the core of the Earth and we have scarcely even scratched the surface in our exploration of our own planet. We actually know far more about what happens in the core of the sun!

The only way the Earth can cool is by radiation into space. There are those who believe that the Sun replaces the energy lost by the Earth exactly, so according to them, the Earth's core will not cool until the Sun dies. Others believe that the Earth is heated as well by nuclear reactions in the core.

this is going to! Its decrease than extreme stress nevertheless down there on the middle and stress = warm as you will comprehend from physics. ultimately the earth will quiet down. even though the sunlight is going to swell up and in approximately 5 billion years its perimeter would desire to embody the earth so as which will heat us up somewhat, I reckon.

A very long time from now, no one in this generation will never live to see it though. It will take billions of years for it to happen.

No one alive today will ever find out for sure. My opinion though is that probably not, because of the constant shifting and friction of tectonic plates.

yes we are living on the old sun which in time will turn into the new moon. yes we are all living on a fossil and when the fossil runs out we die unless Theres an explosion and we get flung clear ,

Never. The pressure from the weight of the earth is what keeps it melted.

Buddy, possibly, with all due respect to you, reality cools down.

Yes, definitely, in billions of years.
