1. ## Revolution!!!!

Not to say that the rest of that post wasn't a piece of rubbish but: Acceleration is constant. It is velocity and distance traveled that have increasing or decreasing values when an object undergoes acceleration.

3. ## Properties of Creationists

Evolution isn't an opinion it's a theory, backed by real world evidence. Creationism is an opinion backed by a book.
4. ## Gravity and length

You're wrong on the first count. But you're right about the equation being useless in this context, I don't know what I was thinking. Testing: $L = \frac{L_0} {\sqrt{(1-v^2/c^2)}}$
5. ## Did I miss the point of Schrodinger's Cat?

Can the cat destroy its own wave funtcion by observing if it's alive or dead?
6. ## Gravity and length

L is proper length, L0 is mesaured length. L = L0 / sqrt(1-v^2/c^2). So how do you use latex again?
7. ## The average height of American?

I'm 17, 187cm 80 odd kg and wear size 46-7. And I've had to shave everyday since two years ago. But I'm not american.
8. ## Guess what im "syinag"

Man, put a waring or something. My spelling will be scrambled for ages now.
9. ## Waves of water and sound.

I believe that in classical mechanics the Aether was introduced to explain how they could move through space. It was not until relativity that that was rejected.
10. ## Gravitational potential at center of Universe

There is no one point center of the universe. Relativity shows this to be the case since every observer in constant motion can claim that he is stationary and every object on average is moving away from him. Due to supersymmetry there is also no net force on the largest imaginable scale.
11. ## Spherical Theory

The solar system isn't a sphere and neither are many galaxies. Superclusters are just a mess and the same applies to the way they seem to interact with themselves. So in short everything obeys the forces acting on it and not a specific shape.
12. ## Absolute stationary

What you are describing seems to be the aether. By the early 20th century attempts to detect the aether (or, more specifically, attempts to detect the planet's movement through the aether) had called the concept into doubt. It was formally dispensed of by the work of Albert Einstein of general relativity which held that there was no one stationary point in the universe from which everything was moving away.
13. ## Doppler effect

If by work you mean work out, I did it in my head. If by work if you mean how does it work, I don't know if it does, I'll have to try it out on the software at school to see if it does anything right. Since I can't get there till next week that's why I posted here first.
14. ## Doppler effect

I was thinking of how to represent this on a graph with (0,0) being the source of the wave. After some though I came up with: y=x^2*y^2*t*(w-Vsin[theta])+x^2*y^2(Vsin[theta]-w) t= time w= speed of wave in the medium v= velocity [theta]= angle taken at right angle to motion counter clockwise. This is probably wrong but I can't find it on google and got too bogged down to think it through again.
