The periodic times argument of Kepler27 Jun 2006 18:37 GMT9
The creation of the AU by Newton  through the so-called 'periodic
times' argument of Kepler is unjustified,undignified and outright
fraud.
If a participant is not capable of matching Newton or not capable of
What Exactly Happens to TIME in GPS Orbit? 26 Jun 2006 23:39 GMT235
Relativists claim that GPS clock remain unchanged when sent into orbit. They
seem to think that something happens to TIME itself and this causes the clocks
to appear to run fast when seen from Earth.
Could one of the experts from the lunatic fringe please explain this process in
It seems that ALL atoms are charged capacitors26 Jun 2006 16:54 GMT13
A capacitor has the positive charges (+) grouped together and the
negative charges (-) grouped together LIKEWISE ALL ATOMS (neuclus vs
electron shell).
If similar charges are not grouped together in a capacitor, the
Time dilation mirrors perpendicular to motion26 Jun 2006 11:24 GMT20
In James Hartle's book Gravity (An introduction...) he runs through the
maths of deriving time dilation from a pair of mirrors aligned parallel
with their motion.
He then sets the same problem for a pair of mirrors aligned perpendicular to
A site that tells me how old people were on a certain date?26 Jun 2006 01:12 GMT4
Hello, I have no idea which newsgroup to ask about this. One can find
websites for just about anything on the internet so I thought there's
no harm in asking.
For example, let's say an athlete was born on January 1st 1980 and wins
Why does Capacitance decrease with "r" but F decreases with "r^2"?25 Jun 2006 21:08 GMT33
Wheter the capacitor's dielectric is space itself or another material,
why does Capacitance decrease with "r" but F decreases with "r^2"?
It would seem logical that if the attractive force between the charges
SUBSTANTIALLY decreases by r^2 then it doesn't seem logical that the
Gravity - Caused by GR curvature or gravitons?25 Jun 2006 19:39 GMT174
As I understand it, Einstein's theory of General Relativity (GR) seems to
describe gravity as being caused by curved space-time alone. No gravitons
are necessary. However, quantum field theory is said to predict the
existence of a graviton (which is massless, like a photon) and ...
Cosmogony from the Book of Genesis.25 Jun 2006 12:57 GMT36
Let us contemplate the following...
1: In the beginning God created the heaven and the earth.
The heaven and the earth refers to the double-sheeted spacetime, namely
the two Kruskal-extended Schwarzschild solutions exterior to the event
Does H2O contain two electrons of hydrogen?25 Jun 2006 10:27 GMT4
I forgot my chemistry:
I found:     H2O + energy = 2H2 + O2
1. I believe the H2 in H2O are two electrons of hydrogen, correct?
2. Where did they get the four protons of hydrogen to produce: 2 H2 ?
Can anyone describe the differences here?24 Jun 2006 16:22 GMT37
There is a rotating cylinder aligned along the x-axis.  There are two
rods near the surface of the rotating cylinder going from end to end
of the cylinder.  There is an inertial frame moving with velocity V
with respect to the cylinder frame along the x axis.  At time t0 as

I have read nothing in the ongoing thread and start a new one because it was
only after I deleted everything in the new download that I thought I would
comment.

The atheist movement came into existence by accident.23 Jun 2006 08:00 GMT6
The atheist movement came into existence by accident. After it appeared
that the universe was infinite in size in Isaac Newtons time.
Mathematicians had a difficult time in expressing Infinity in Geometric
terms.
