I usually don't answer many questions in physics, I passed my only phsysic class and then forgot everything. But I was wondering is there as many anti-Bing Bang creationist questions/answers here. Because in Biology there is always a creationism/evolution question. Also why is it that many are not enraged over the Big Bang as they are evolution. Could it be that evolution is taught more in school? because i dont remember learning much about it. What i learned about it came from wikipedia on my own research. So whats your thought on this?

You could build a hypercube in 3D, so why is it in 4D?

I thought the fourth dimension was time.

Long ago -- probably in 1990 or 1991 -- I saw in a magazine a picture -- In that picture -- a feather and an apple were dropped at the same time in vacuum -- the picture is like this -- at top of the picture the feather and the apple are at the same position -- then probably after 5 sec another picture is taken and superimposed on the old one -- so now there are 2 feather/apple duo stacked on top of the other -- and -- like that there are many instances -- and at the last instance it was seen that feather is a bit closer to the ground than the apple -- some thing which means there is more force between the feather and the earth -- than -- between apple and the earth -- does einstiens general theory of relativity predict this -- I dont claim to have a theory which rivals GR -- I know nothing about GR -- while free I read some popular science books on physics -- just being curious -- the magazine where I saw the pic was "span" -- it is an american magazine published in India

A car is traveling along a straight road at a velocity of +37.0 m/s when its engine cuts out. For the next ten seconds, the car slows down, and its average acceleration is 1. For the next five seconds, the car slows down further, and its average acceleration is 2. The velocity of the car at the end of the fifteen-second period is +20.6 m/s. The ratio of the average acceleration values is 1/2 = 1.52. Find the velocity of the car at the end of the initial ten-second interval.
__m/s

1. A circular disc is rotated about an axis O through its center by the application of two forces. A force of magnitude 11 N is exerted at a distance of 0.34 m from the axis and at an angle of 58° from a radial line extending from the axis through the point of application Q of the force. A second force of magnitude 15 N is exerted at a distance of 0.26 m from the axis and at an angle of 119° from a radial line extending from the axis through the point of application P of the force. Determine the net torque on the disc about its center and which way the net torque accelerates the disc.

If energy cannot be intelligent with out matter (matter and energy can be intelligent, because we are so)
matter cannot be intelligent on its own because it would have no way of transferring information... you need energy for that

but why can't energy be intelligent?
is it because particles are unpredictable?
why can't light be intelligent?

A roller coaster (420 kg) moves from A (5.00 m above the ground) to B (18.0 m above the ground). Two nonconservative forces are present: friction does -2.00 104 J of work on the car, and a chain mechanism does +3.00 104 J of work to help the car up a long climb. What is the change in the car's kinetic energy, KE = KEf - KE0, from A to B?
