An object subject to a gravitational field must accellerate.  That is
is must constantly increase speed.  This is easy to see because when
the object is first "dropped" gravity causes it to change speed, so at
every point along the way gravity is operative and so causes an

According to Special Relativity, mass become infinite when light speed
is approached because of the factor:
1) 1/sqrt(1 - v^2/c^2)

A long, long time ago when UFOs were often in the news I remember reading
that a reasonable explanations was many sightings were of plasmas. I suspect
that's true, but has anyone developed these ideas further?

"There is no absolute rest." Albert Einstein
This can mean that everything is moving in some way through space.
Relative rest is co motion of two objects moving together at the same
speed in the same direction.

I have a couple of questions regarding pressure and its definition. I
know that pressure is defined as force on some surface. 1Pa = 1N/1m^2.
I know that this is very small pressure and zhat in life a much higher

an especially interesting (arguably) paper:

You may see the Schrodinger equation as a general law that is valid

Energy of motion is given by the Gamma factor. It is the concentrated
energy in point particles that begins at C^2 and increases with
acceleration because it creates more concentrated energy of motion.

"The Paradox of Zeno"
    The Paradox of Zeno is 2000 years old and its apparent ability to prove
that all motion is impossible was not resolved until the mathematical
techniques of Calculus became available, even though that technique is not

I believe it was in the 1940's Einstein wrote that he could not
reconcile both a wave and particle property of light at the same time.
In other words he was questioning what he won the Nobel prize for. I
follow Einstein's later thoughts on the matter. I do not believe in
