first post in NG --blackbody question09 Apr 2007 13:29 GMT6
I understand why blackbody radiation is spread out due to the doppler
shift of the atoms, but why do hot objects give off photons?  And
where do the photons come from?
If they came from the dropping of electrons to lower energy states,
Does light aberration occur all around the source?09 Apr 2007 10:03 GMT4
(Einstein's relativity, doppler effects and aberration of light)
Say the aberration angle = phi
When phi=0 (no aberration) the light is observed directly on one axis
.... So say when phi = 80 degrees, does the light aberration occur
transformation equations09 Apr 2007 06:27 GMT693
Since the Lorentz equations were applied to the problem presented
to physicists by the Michelson-Morley experiment, mathematicians have
universally agreed that they have proven mathematically that the only
equations that could possibly exist as transformation equations that
Velocity09 Apr 2007 01:21 GMT24
I saw this following explanation in a popular book on relativity.
We have a space ship that expends enough energy to accelerate to 15 c.
Next, we observe that ship and measure its velocity.
Surprise, its velocity is below one c.

The Voice of Religion.08 Apr 2007 19:08 GMT8
Since relativists preach their myth with religious verve, the 'Voice of
Religion' message below is equally applicable to them.
THE VOICE OF RELIGION.
I bought a striking 500(?) year old painting of the Holy Family depicting
speed of light inconsistency08 Apr 2007 17:01 GMT2
while tha speed of light is close to inifinity, for
an information packet transported by light, take an event
or an image for instance, it gets pretty confused

opposite, complementary and the "not even wrong" ways of thinking07 Apr 2007 16:27 GMT2
The opposite and complementary ways of thinking and the "not even
wrong"
Amongst different ways of thinking we are entitle to choose and stick
to a personal line of thought.
SR clock sync problem07 Apr 2007 14:55 GMT13
In solutions to various problems (as in the twin's paradox) clocks
appear to get reset when frames are changed.  And the change in time
is a function of the distance of events, although in any given
reference frame distances between clocks have nothing to do with clock
Einstein elevators thought experiment07 Apr 2007 14:48 GMT147
Excerpt from Strobel's Astronomy Notes.

"Part of Einstein's genius was his ability to look at ordinary things
from a whole new perspective and logically follow through on the

It has also been proposed by some, that the blue flash

My Absolute Reference Frame07 Apr 2007 01:55 GMT6
t'=t/gamma
How do yo like that!
dt'/dc appears a solution while the solver tests always. SO in science
we always test the constancy of light as a truth.
Draft on Set Theory and Development of Special Relativity06 Apr 2007 23:57 GMT7
It is clear now that Garciadiego’s book  on the set-theoretica
“paradoxes” (BERTRAND RUSSELL AND THE ORIGINS OF THE SET-THEORETI
'PARDOXES') is a dagger pointed straight at the heart of Gödel’
theorem.  Above all, this devastating book demolishes not only Jule

Modern-day religions!
  Religions are important!  A man's religion is one
of the most important ways we have to judge a person,
because religion can be freely invented.  It is
length contraction  difficulty06 Apr 2007 13:06 GMT34
I posted a simple example of moving a rod from one inertial frame into
another which showed that length contraction of the rod cannot take
place instantaneously.  The consensus of reponses basically thought
that the nucleus of each atom reached their proper length almost
