How big was the universe (and in how many dimensions) before the big bang?
If I dug a hole in the earth and drove into it at the speed of light, would my headlights shine all the way through?
Could I have traveled back in time to fake the moon landings?
If the earth stopped spinning because of a black hole, would we notice (since my cousin's trashman said there's no such thing as centrifugal force), and would that turn off gravity and change the color of the sky?

And please hurry, this is due today and I don't want my teacher to yell at me.

The correct answer is c, for reasons too complicated to explain here. However, scientists are uncertain as to whether this would stop Pluto from being thrown out of the solar system.

1) A single point where all the laws of physics don't exist.
2) Now, where are you destined to go with that speed and immortality?
3) Erm, sure but can anybody fake their own existence?
4) God created the Earth, only He knows.

I can answer part of this question..
if y ou are traveling at the speed of light, in your car, assuming its possible, the light beam would be moving away from you, yeap..a t the speed of light... relative to you....in the car.. sounds weird..
gravity is not due to the earths rotation, but to its mass interacting with your mass.
according to Einsteins theory of gen. rel... mass itself tends to warp space, hence what you feel as acceleration is just space curvature near a massive object...
I think!

i) Nothing existed before the big bang, in any meaningful sense as that is effectively t=0 as far as our universe goes. The question, as it is phrased, is meaningless
ii) Only massless particles can travel at the speed of light, therefore you can't have headlights.
iii)No
iv)Yes, no and no.

a) OH! Please wait -- I need to get a couple of Tylenol!
Okay - zilch (dimensionless singularity - space wasn't) "Before?" hmm, lower clocks go slower, so maybe there wasn't a before
b) Not even in your Porsche Boxster
c) Only in So. Calif.
d) After sniffing 'nuff glue, maybe.

If the earth stopped spinning, we would all float off into space. That's because the centrifugal force of the earth spinning is what causes gravity. I would explain it to you but I just don't have time right now.
