If how big is it, is there an end or is it infinite, how did the universe began, who made the universe, are there any living organisms outside our planet, is it intelligent, what do you think about dark energy, the black hole, and so much more. Make your own theory. I want to know what is your mind capable of.

A charged particle under acceleration should radiate energy. Since an electron revovling around the nucleus constantly changes diraction, it is constantly acceleration and it should be constantly losing energy. As it loses energy, shouldn't it be getting closer to the nucleus and eventually collide with it? What is wrong with this?

I am referring to a body that has not been embalmed. How long would it take to begin to decay after death, not to the bones stage, but just until the smell and look of the corpse clearly showed decomposition. Thanks.
