I don't understand how gravity works

Gravity works because of fairies. The heavier something is, the more fairies it has, and they're all wanting to get together with all the other fairies and fornicate like mad, well, fairies.

No, you cannot make Jell-O (or any gelatin based dessert) with fresh pineapple. This is due to the presence of an enzyme called bromelain in the pineapple. This enzyme is a protease, which digests (or breaks down) the collagen based gelatin protein. The digested gelatin cannot solidify and you end up with a soup instead of a gel.

Cooked or canned pineapple can be used in gelatin desserts, because the heat used in canning and cooking destroys the bromelain.

It's most likely an electrostatic dipole effect of some sort. There are BIG problems with Einstein's attempt to describe it as some sort of a four-dimensional differential geometry thing.

Scientists from the Evangelical Center For Faith-Based Reasoning are now asserting that the long-held "theory of gravity" is flawed, and they have responded to it with a new theory of Intelligent Falling.

"Things fall not because they are acted upon by some gravitational force, but because a higher intelligence, 'God' if you will, is pushing them down," said Gabriel Burdett, who holds degrees in education, applied Scripture, and physics from Oral Roberts University.

Burdett added: "Gravity"which is taught to our children as a law"is founded on great gaps in understanding. The laws predict the mutual force between all bodies of mass, but they cannot explain that force. Isaac Newton himself said, 'I suspect that my theories may all depend upon a force for which philosophers have searched all of nature in vain.' Of course, he is alluding to a higher power." ...
