You mentioned mass gains some mass (weight) as it warms up. Heat has no mass so where does the extra weight come from. Does it lose that weight as it cools off?I don't think so, though I'm really not sure what you're asking, you seem to be conflating mass and volume.
I'm saying energy and mass are equivalent.
Mass that is motionless has no energy. Motion is the energy part.
A hot gaseous body like a star exists in a state of balance between gravity trying to shrink it down and radiation pressure trying to expand it. When it runs out of fuel and the radiation pressure drops it'll certainly implode, and depending on its mass it'll do something like shrink down to a white dwarf or rebound into a nova or supernova.
I'll add some more to thisNo, there'll be no effect at all.
Pick a bigger star then. My point is the sun is rotating like all bodies in our solar system, that makes the poles the weak pint so implosion cannot take place as that would need forces to be equal and they aren't in any body that is spinningThe sun's too small to explode. According to current understanding it'll go through a red giant phase as the nuclear processes at its core use up the hydrogen and it shifts to fusing other things, when that's all done it'll shrink down a white dwarf and gradually cool into a cinder.
So your shortcomings are proof some others have it right?? Right down to matter coming from nothing?? I'm smart enough to see a false conclusion and that is one of the bigger ones but nobody cares. The Megaliths are another blank for modern science but they still have all the right answers. It needs a review from square one and people deserve a huge refund when they get lies and pay lots of money for the truth'It's the best explanation we have so far, a lot of people way smarter than I am have worked it out and convinced a lot of other people way smarter than I am, so yes I do think it's worth taking seriously.
That like saying 10 wrong people make a correct conclusion when all they are really doing is saying whatever they need to so they hold onto their job.
