Should there be a limit to stop any indiviual posting successive questions especially exam type ones. They just remove other questions from the same page where other contributors want a reply?

Big Bang

Now that we are able to analyse the movements of the galaxies has anyone ever plotted their movements and extrapolated back to determine where in space the big bang occurred? If so what is there now?

Big age differences Gender Assymetry

Why does society look differently at the older person in say a 35-year-old-with-16-year-old relationship if the older person is a man, compared with one where the older person is a woman?

how does it work?

Is there a scientific principle that explains how the universe operates, does it adhere to a set of rules or is completely random? Bit heavy I know........but facinating.

Who knows

If time is relative to speed, and all the parts of the universe are going at different speeds, how can we be sure of the distance to any other part of the universe? As we refer to light years.

Matter........Antimatter Gravity.........Antigravity?

Just as there is antimatter, are there any grounds for suggesting there is such a thing as Antigravity . And could it be the force that keeps the universe expanding ?

Mutation

A mutation that deletes one or two DNA nucleotides changes gene function more drastically than a substitution of one nucleotide for another. Why?

Sharia Law

Did anyone see tonight's BBC documentary on Sharia Law in Nigeria? Any thoughts, and do you think a duel system of Sharia Law and British Law could work here?
