I hope you know how much you have to explain here and maths alone will get you nowhere because maths doesn't know anything about spacetime nor about forces etc... but ... so what ?

Well, think about it. Mathematics doesn't tell you that spacetime has four dimensions. Maths would work the same way with 10 or 5000 dimensions. e=mc^2 could be about apples and pears. The maths doesn't tell you that electromagnetism is a force. That's why physics uses maths extensively but it not synonymous with maths. Logically all mathematical equations no matter how complicated are mere tautologies. You could describe any universe with the same maths. Maths doesn't tell what your universe is like. It's not empirical
Gosh, dryson, if you really want to explain singularities this way, you have an awful amount of observations to explain.

The show talked about the Sun's core, the Earth's core and then went on to talk about IO and why it's volcanoes were active. The discussion continued on about the layers of Saturn and that there was not any type of active core what so ever but instead only gravity. Since there is not an active core like the Sun or Earth's present then what type of core is keeping the planet together? The only answer would ahve to be either a miniature black hole, or a gravity singularity.

Though there is no direct information about Saturn's internal structure, it is thought that its interior is similar to that of Jupiter, having a small rocky core surrounded mostly by hydrogen and helium. The rocky core is similar in composition to the Earth, but denser. Above this, there is a thicker liquid metallic hydrogen layer, followed by a layer of liquid hydrogen and helium, and in the outermost 1000 km a gaseous atmosphere.
I must respectfully disagree. There a significant body of evidence that beer is actually beneficial, and no one explains it better than Cliff at the Cheers Bar:dryson":17knfyyy said:When you drink alcohol the brain cells are killed ramparts and do not grow back. It also goes to show that when you drink any amount of alcohol your thinking process's become impaired.
Here is a link that proves what I am saying is correct.
