Infinity is 100 years long, at best, less if you go earlier, a litle longer if you look after yourself. Life cannot be considered infinite, only Death.

Sorry if this bummed you out...!

If we live in fluid space, the plannets should be thought of as bubbles, in it, depending on the bubble, gravity, (or the fluid outside the bubble wants to push to its centre), could'nt this explain gravity, or the effects of it, so depending on the size of the bubble, and its density will be directly proportional to the gravity felt.

Anyway some thought... what a boring saturday night im having....lol
