We can literally replicate the same mechanism of the sun on a small scale. We know that the sun is a large scale nuclear fusion reaction. We know that it is not infinite because we understand the mechanics on how to create it, as we have done so ourselves. We simply have no means on actually predicting the death of the sun because it will always boil down to unprovable theory with no actual material to substantiate.
The sun is powered by a hydrogen fusion reaction of a kind we cannot produce on Earth (for various reasons, having to do with thermodynamic conditions and timescale of operation). We compare our observations with what is predicted by theory and find good correspondence. Theories are never "proven"; they are either verifiable or not. Sometimes a good theory is displaced by a more elaborate or more accurate theory when fine details are examined.
If you believe scientists…
Or physics
Mate, you still believe white men walked on the moon… so don’t pretend you have any working knowledge of physics…
