Dyson sphere

[Hielor]

What i barley managed to take in from that video (due to a massive headache) there is a chance it could be possible, since there has been stuff in the past once thought impossible and denied to the ends of the earth, then we find the evidence, and poof, it's true. So I'm going with a hypothesis of that it is hollow on the inside, but for it to be possible the "inner crust" must be incredibly strong since it has all of the "outer earth" weighing down on it, and as Hielor mentioned, gravity, anything that does exist on the "inner surface" would get sucked into the planets core. but now defending it, since we do have proof that the core is molten metal, and unless I'm confusing Minecraft physics with real life physics, that would emit light without needing nuclear fusion and it wouldn't need to prevent collapsing in on itself because It would just be a big ball of molten mass.. (brain power running out at this point, might start to sound weird) and it shouldn't dribble down ontop of the "inner surface" since its sucking itself together due to its own gravity, and wont go splat or anything because most of the mass will be in the centre, so the gravity will be strongest there, so It will keep pulling in the outer side of the core, so yes, the core should stay sort of floating in mid air since its mass would be strongest around and thus keeping itself together with the most force.. umm.. right, all ability to make sense from my wonkey logic has gone. so good night, and I hope somebody out there has the ability to process the bonkersness that is the "logic" in my head, and if you do have the ability to, god help you, because making sense out of this must of turned you into a potato.

Edit: spontaneous glimmer of a working brain cell. It would be REALLY hot inside so unless they're evolved right and uber heatproof tech for food etc to grow/not melt.

Except you still missed the part that nothing can stick to the inner surface because it's not spinning fast enough, so anything on the inner surface would just fall into the molten core.

So you have an eminently logical model which is the currently accepted scientific model for what the inside of the Earth looks like (it's not hollow), versus a ridiculous "model" that pulls random nonsense out of its butt and ignores important laws of physics.

I think I know which one is more likely to be true.
