The stars are powered by nuclear fusion. The core of the earth experiences nuclear fusion too! We experience star making inside the core of the earth.

So that’s where Barbara Streisand came from.
Cool.

from what I heard they will all burn out. Does anything last forever?

Nothing last forever except the void, the void is made of particles that pop up and out of existence. As far as the physics I know

So there will always be something? As far as science can see there will never be a time when nothing at will ever exist.

Yeah. As far as physical objects goes, there’s always something. Philosophically things are different - but that’s where pseudoscience gets involved so I don’t think of it because it turns into semantics usually
Are you interested in fusion?

I am fascinated by the Universe. And apparently fusion is part of it.

I used to read about nuclear physics. I had a theory that was proven false. A man I know really stuck it to me for being wrong. New experiments had been done that proved me wrong. It’s been so long I don’t remember the terminology, but I remember the basic concepts

There is no nuclear fusion in the core of the earth. It is not big enough. You need a planet 13 times the mass of Jupiter for fusion to occur. Fusion occurs due to gravity.
We’d collapse under gravitation effects if nuclear fusion wasn’t there?
No he’s saying there’s no fusion in the center of the earth
The planet would need to be much larger
The planet doesn’t need to be larger. Why else would we be trying to create nuclear fusion reactions on the planet?
Fusion prevents stars from collapsing but the earth isn’t big enough to need that.
According to current scientific understanding, there is no significant nuclear fusion happening in the Earth’s core; the heat generated within the Earth’s core is primarily attributed to the radioactive decay of elements like uranium and thorium, not fusion reactions, as the conditions of pressure and temperature are not sufficient to initiate fusion on Earth.
Larger planet= more pressure and heat = fusion
Yeah but there’s fusion too. @Mars fusion isn’t to stop gravity, fusion just happens to do that for stars. It’s just a chemical reaction process

Do you mean fission?
Fusion isn’t heat, fusion is the explosion! (The reaction itself)
Yeah but heat can lead to fusion
No, literally google it. It says both happens
