Thank you again for your kind reply. I am not trying to be difficult but have difficulty in understanding some of these things. You said If our universe contracted to a single point . . . the entropy would be the highest possible number. But, no matter what you do, entropy of the universe...

Thank you for your friendly reply, but if a system contracts don't the contents go back to where they started and doesn't that mean back to the same entropy and I saw something about universes being parts of bigger universes and collections of universes. What if you don't know about a nearby...

Size can mean a lot of things like distance across or how much stuff in it. It also depends on your viewpoint like an atom nucleus must look pretty big to an electron.

Excuse me I am new here. Is a shrinking universe a closed system cos to me it suggests it is going in an opposite direction and might keep changing indefinitely. Also I heard about going in cycles throughout single point things. I saw somewhere about what is the entropy where it changes and...

Shouldnt those who put stuff up there be responsible for the consequences like when it falls down? Like here you cant just dump stuff on the highways or let stuff block them
