Natural Science Forum / Physics / Relativity / July 2008

As we speak, they still won't answer the fundamental questions
Why? Because this makes relativity no more
Let us for now assume that inside my spaceship things ages slower
regarded some other ship at home in a hangar.

I believe that I just predicted the mathematical beauty of relativity
by mistake.
Look, if you go faster you get
c = c + v

It is generally believed that it took hundreds of millions of years
for our fossil fuel supply to be
created. On the other hand it could only take a few hundred years for
us to burn them up.

From a modern point of view, magnetism is a relativistic effect.*  If
you believe magnetism is real, then SR effects are real.
Is it worth 1000 posts and bitter arguments to debate it?

I came across a description of how gravity loses energy making gravity
waves.  The "thought experiment" involved Atlas and two great iron
spheres.  Basically the argument is this.  Atlas throws the spheres in
opposite directions (at equal velocities) and when they come back they

I've found out that in vacuum, the relation between
signal velocity (v_s), group velocity (v_g), and phase
velocity (c), for electromagnetic waves, is
   v_s = c tanh(v_g/c).

I have done my own regression analysis of the unbiased spectroscopic data
taken on hydrogen and presented at:

See Table 8.2. A linear regression can be performed with the third column as

"The Lorentz Transformation for Velocity"
    It is recognized that Special Relativity provides the Lorentz
Transformations for Length and Time and Mass between reference frames having
a relative velocity. What is too often not recognized that, in so doing, it

Schrödinger's Universe
One of the very best books, that has recently come out, is Dr. Milo
Wolff's brand new book: Schrödinger's Universe.
I've just now finished reading it and I predict that someday it will

Some time I still have the feeling that I understand Relativity
Then again, I have the feeling that I do not understand.
This confuse me even more!
How many years of study takes in order to completely not understand

The usual argument for massless photons uses the Hamiltonian
H = (\sqrt (m^2c^4 + p^2c^2) )  (1)
and set (m = 0) to yield
H = pc

Truncation of superluminal speeds:
Let us consider a massive particle moving at superluminal
speed s, such that
      s = c + v,

dear friends,
i m so curious about theory of releativity, so i want to join dis
group....
anyone from dis plz discuss wid me about issues related to it....

I posted this at alt.sci.physics but this is probably a better
place....  Sorry for the doubling up.
Please pardon the simple question, but
if there is no hierarchy for frames of reference, how does one decide
