If the Universe is expanding, what is it expanding into?

I'll combine physics and astronomy:
Did we really go to the moon?
What was before the big bang? (Can you prove god didn't go it?)
Why is the sky/sea blue?
If I were going at the speed of light and turned my headlights on....?
Can I go faster than the speed of light/travel back in time?
What is quantum mechanics? What is relativity? What is string theory? What is
What would happen if the earth stopped spinning?
What would happen if I fell in a black hole?
How big is the universe?
How many dimensions are there really?
Why does my friend/teacher/dad/garbageman say there is no such thing as centrifugal force?
If I drill a hole through the earth, what will happen when I jump in?
What causes gravity? (or occasionally one of the other forces)
Edit--I have to give thumbs-up to Santy for just answering the question. Too funny. Maybe he'll take a crack at the rest of them?

They come in two categories: HS physics and advanced physics.
HS physics questions are related to the SUVAT (distance, velocity, acceleration, time) equations (like v = u + at). They also relate to Newton's three laws of motion and his gravitational law. Finally, the conservation of energy and of momentum laws are also popular questions. In other words, the askers are typically HS physics students looking for some help with their homework.
Advanced physics questions are related to relativity, string theory, and quantum mechanics for the most part. There are a lot of questions like "If I'm traveling at the speed of light and turn on and shine my flashlight ahead of me, what happens to that light beam?" Or "What are the eleven dimensions of string theory; what do they mean?" These are questions typically asked by curiosity seekers who have read a little bit on a popular web site or in a book about the subject.
There is a miscellaneous category (all others), which is made up of questions around Coulomb's law, Pascal's law, aerodynamics, and others that are taught in HS and introductory college physics.

The sunlight is a composition of 7 wavelengths or colors(VIBGYOR).The blue light gets scattered more than others by the earth's atmosohere.

Wouldnt the answer to this question require a question in turn?
I dont know about the most popular questions in the past, but I do know the LAST question that was asked..............and it was yours!!!!
Hope this helps

The most popular question:
Can you do my homework for me?

how does that make you feel.
that seems kinda obvious though. sry if I'm no help.
