I don't mean at the receptor end but dispersion? Why some are more pungent than others. How far does it travel? Why can an odor cling to fabric, and other things.

My father has the idea that maybe, just maybe after a beam of light has traveled through space for a few million light years, it might slow down a little. Any thoughts on this subject?

I understand that lightening has millions of volts and thousands of amps. I also understand that a bolt of lightening is 5 -15 times hotter than the sun. Do we have the technology to attract lightning and transform its electricity into usable power? If not, is it theoretically possible?

If any physicists care to answer, here are the details: if I jump off of a balcony that is 3.28 metres above the specified chandelier (located where the acceleration due to gravity is 9.78 m/s^2) at an initial speed of 14.9 m/s and I leap 0.61 m high with respect to the initial point of take-off (the balcony), is there a good chance I can swing on it without bringing the whole contraption down? I don't know any specifics about the chandelier except that it costs just over 6,000 USD. An estimate is appreciated from anyone, but especially physicists.

I think that gravity is caused by a mass retarding the rate of time near it and that we experience this retardation of time effect as gravity.
Can anyone tell me a good reason why my thought on this could not be true?

I'm programming a small computer game and have run up on the following math problem:

Two objects exist on a two dimensional space. One is a moving target, the other is a stationary shooter, firing at the target. Assume that I know all of the following:

The exact location of the shooter and the target at any given point in time.
The distance between the shooter and the target at any given time.
The velocity and direction of motion of the target.
The velocity of the projectile. (constant velocity)
All conditions are ideal: no friction, no changes in velocities or directions, no wind resistance, etc.

How can I determine what direction the shooter should fire in to hit the target at any given time?

I've been racking my brain for a couple of days, and can't figure this one out. Any help is greatly appreciated.

A rancher friend of mine asked me this question today and I thought it was too complex for me to answer as I am a carpenter and this does not come up in my line of work:
If a water supply containing 10 acre ft of water is 100 feet above the land to be irrigated and has a slope of 45 degrees, a regulated 12 in pipe is inserted at the bottom of the reservoir as the pipe gets smaller the pressure becomes greater but the volume gets smaller. The question is what is the greatest size pipe at the bottom of the grade that will give 125 psi. the slope is 300 feet long and at the bottom the pipe will be attached to a sprinkler system the pressure cannot exceed 125 psi. This entire system is gravity feed.

I have developed a very detailed model of gravitation that suggests this is the case.

If the influence of gravity decreases as you move away from a planet, shouldn't Einstein's equation be E = wc^2? For example, does an object dropped on the earth yield the same energy as an object dropped on the moon?

The physical theories dealing with very small things, like electrons, disagree with the physical theories governing things like celestial bodies. Is it possible to find a theory that makes them agree? Does string theory make them agree?
