einstein was right31 Jan 2007 18:17 GMT9
einstein was right, quantum physics makes no sense,
it is only becaUSE wrong mathematics which is'not physics
The predictions of special relativity31 Jan 2007 09:45 GMT13
Almost all of the predictions of special relativity are predictions of
the effects of changes in motion on the equations with which we model
physical phenomena. They fall into two classes:
(a) A change from one reference frame, A, to another, B, in motion
Einstein S.O.L and mirror thought experiment?31 Jan 2007 05:33 GMT1
Albert Einstein made the thought experiment of travelling along with a
beam of light, at the Speed Of Light, holding a mirror outwards in
front of his face, to observe what happens to his reflection.
What would the consequences be if one replace's the mirror with that
tensor "reverse trace" operation?31 Jan 2007 00:17 GMT5
The wikipedia article on the Einstein field equations makes the
statement that
  R_uv = (1/2)*R*g_uv
reduces to
Sorry, I've been having News Server Problems.30 Jan 2007 22:36 GMT11
That's right. My server has not been posting or receiving messages for three
days so I have reposted all of mine. Sorry about that.
In case you think I was running away from your questions, I wasn't.
Some Idle musings whilst flicking through the Usenet Physics FAQ30 Jan 2007 21:42 GMT6
Whilst idly thumbing through the Usenet Physics FAQ (http://

Ping Tim, Spacetime Isotropy.30 Jan 2007 17:37 GMT6
Hi Tim et al, fascinating stuff.
65,000,000 years ago a T-Rex ate a Triciratops.
5,000,000 years ago Tim and my common grand
mom started walking upright.

Again and again about the result of MMX30 Jan 2007 10:50 GMT58
It is shown http://vps137.narod.ru/articles5a.html that the MMX
as the key experiment in the affirmation of the theory
of relativity has not a suffecient sensibility to fix the velocity of

massless phonons30 Jan 2007 07:44 GMT5
i dont knoe about photons, but phonons has no mass
can you weight a phonon? you cant, can you?
consequently, you can trap a photon becus is heavy matterial,
but you never can trap a phonon
The Hypergeometrical Hyperon Family30 Jan 2007 02:24 GMT2
I developed a fully geometrical representation of the Universe and am
now explaining the Hypergeometrical Standard Model.  The first
instalment is the Hyperon Family.

if plank constants are wrong30 Jan 2007 01:13 GMT1
if the smallest amont of energy postulated by planck is smaller
or even is continuum till infinitismal then quantum physics is
dead
it is dead, but relativity still alive and kicking
is time orthogonal on which axe?30 Jan 2007 00:20 GMT1
accortingg dimension  definition, time should be orthogonal
either on x-axe, y-axe or z-axa
what is time t orthogonal on?
the art of tensors29 Jan 2007 22:25 GMT8
most people, mostly them pretending understand and using tensor, have
no idea what a tensor stands for
when you do tensor you automatcly do discretization, then doing it
you lose simultaneity, then it makes no sense using it in relativity as
wrong relativity or simultaneity exists29 Jan 2007 22:13 GMT5
i new blatant error i discovered just i walked back to
my home from outside
in relativity al the tension elements at a particular tensor
then used in derivation, are considered acting simulaneus
