Heck! Why do they light up at all? Why did "evolution" or "God" decide that they need to light up?

I know that recieving 9.5 hours of sleep restores a person immune system, and at least 8 hours guide in effective anabolic activity as well as neurohormone effectiveness. But i find myself quite educated in general biology and medicine, but unfortunately do not know that much about sleep. Any accurate information would be helpful, please get into as much detail as possible in your own words, do not copy adn waste from wikipedia or other sources, as i can do that myself. Thanks.

What if we used 2*Pi as the constant of choice?
Ti = 2*Pi

Then
Circumfence of a circle = (r)(Ti)
Full circle has Ti radians
Formula for volumn of a cylinder containing a sphere = (Ti)(r^3)
Limit as x approaches infinity of (x)sin(360 deg / x) = Ti

The only formula that I know off of the top of my head that is simplier using Pi is the area of a circle, but doesn't it make more sense as (Ti)(r^2)/2 based on the integral of the circumfrance?

A man is on a game show with the top prize of 1,000,000. However, for every percent of money won he has to give that amount of money to taxes. (If he won 100,000, since it is 10% of 1,000,000 he would have to give away 10,000 and keep 90,000). What is the most amount of money he could possibly win if every money value is a possibility.

I have to choose the pairs below that satisfy (f o g)(x)=x

My hunch is pair 2, but I don't know if thats right... i guess there could be more than one pair.

pair 1
f(x) = x^2
g(x) = x^3

pair 2
f(x) = x+2
g(x) = x-2

pair 3
f(x) = 3x
g(x) = -2x

pair 4
f(x) = 2x
g(x) = x/2

There is a huge amount of mass missing in the universe. Scientists believe it is dark energy and matter that makes up this difference between measured gravity and mass. Do you think it is dark energy and if so how is it created? If you don't believe it is dark energy then what do you believe it is?
