Can you prove to me that Gravity isn't just density?

Gravity has little to do with density

What does a force have to do with mass per volume?

>> No.8679265

>>8679251
The point is, this "force" does not exist.
It can not be seen, felt or measured.

Things fall because they are denser than air.

But it is density, mass density + energy density.

gravity isn't a force it's bending of space-time

Are you telling me when I jump up then come down that I cannot feel or measure that force?

Even with this abstract explanation, you could say his model is correct if you assume there is different space densities due to the pressures caused by spacial torsions

Why do denser things fall?

Maybe take a physics class before you start making theories. Or better yet, get a Phd.

I imagine both "models" for Reality can exist, but you'll have to do all the work on the density theory.
It's not as if math or physics are realistic or that accurate; most of their numbers are nonsense.

If gravity is just density than why do things still fall in vacuum chambers? Also, what exactly is the reason that more dense things go down? Some sort of magical force that just makes heavy things fall? aka gravity

it's still not a rind

>>8683102
re your first question the answer I've heard is that nothing has no mass so its density is 0.

re your second no idea what they explain, all I've haerd is "ITS DENSITY THE MASS PER UNIT VOLUME IS THE REASON" but that makes no sense

Yes. If it was an apple skin it would be on an apple and not an orange
