I know scientifically the earth is round like a sphere but Since I was a kid I have always looked at a map and thought it was flat. Even when I look at one today, I can't help but think, "Well what's on the other side?".

This may sound like a dumb question to some people but I am being very serious and am just thinking outside of the box.

If I am to be woken in the night, I first start to experience my dreams and then awaken.So a future event (my waking) directly causes effects (my conscious experiencing of dreams) in the present. Does this prove that time is not linear?

is { } equivalent to {0}?
i think its not because the other set has 1 element in it which is zero.

The scientific definition of a species is if 2 animals mate and their offspring is viable (ie. not a mule/infertile) then they are the same species - then are not dog and wolf hybrids fertile? Does this not make them the same species? Biologists/Zoologists???

(what would happen with a chimp and human?!? -eewww)

Is there only one universe or there are hundreds and thousands and millions of universe just like we have a lot of stars in each galaxy and a lot of galaxies in a universe?

Does the universe has a boundary? What is beyond the boundary?

If you have a standard pulley problem (basically a string over a frictionless, massless pulley) and you've got a weight of W1 on one side and a strong man on the other side. What's the upper limit of W1 that the strong man can pull?

Intuitively, I want to say his weight, but I'm not so sure about that.
