  Big Bang Hypersphere Surface Expansion         


Author: mitch.nicolas.raemsch

The hypersphere started infinitely small. It was full of time and no
matter. The hypersphere inflated beginning at time zero. When it
stopped mass was created spread out in the form of neutrons. The
neutrons then decayed into protons electrons and neutrinos and
recombined as Hydrogen and a little Helium and radiated what is now
CMBR.

  Self-Interacting Fermion Solutions to Dirac’s Equation         


Author: Jay R. Yablon
Date: May 16, 2008 19:17

Hello to all:

If you have followed my recent work to try to obtain a precise measure
of a particle’s “uncertainty,” that is, to be able to find the precise
value of:

U = delta x delta p / (hbar/2) >= 1 (1)

for a given wavefunction psi, will know that I have particularly been
considering wavefunctions of the generalized form

psi = N exp [-(1/2)Ax^2 + Bx -V(x)] (2)

where N is a suitable normalization, and where V(x) is a general,
unspecified polynomial in x.

At this point in time, I would like to take the next step, which is to
consider exact solutions to Dirac’s equation for a wavefunction of the
general form (2). These are what one must ultimately use, if the
uncertainty calculations are to be applied to real Fermions, and not
abstract mathematical wavefunctions.

I have made a start in the five page document linked below: (right

  train observer see both flashes of lightning simultaneously.         


Author: rbwinn
Date: May 16, 2008 19:09

In Einstein's famous train problem, he came to the wrong conclusion by
not using velocity of light correctly. If the velocity of the train
is taken to be positive, then the frame of reference of the train, S',
has a velocity of v relative to S, the frame of reference of the
railroad track. A photon from the lightning at the rear of the train
has a velocity of c relative to S and S'; a photon from the lightning
at the front of the train has a velocity of -c relative to S and S'.
The equations which show these times and distances are the
Galilean transformation equations.

  THE BUG-RIVET PARADOX AND THE ATOMIC BOMB         


Author: Pentcho Valev
Date: May 16, 2008 14:16

Two zombies (or a single zombie and an extremely dishonest hypnotist
in Einstein criminal cult) discuss the bug-rivet paradox:

http://hyperphysics.phy-astr.gsu.edu/Hbase/Relativ/bugrivet.html

and come to the conclusion that, since the "rivet has a kinetic energy
comparable to a small atomic bomb" and therefore generates "a big big
crater on the wall", special relativity remains consistent, absolutely
valid, perfect, divine etc:

The facts:

The whole world is on motorizing as in the industry countries. on the front
China and India.

Crazy cause the world goes kaputt.

Brazilia destrying the rain forests for making bio fuel. The next idiodicy.

I think we just have 182 idiots leading in 182 countries. Whatever they
believe they are idiots.

Cause it can not work that way.

  Flyby and Pioneer anomalies explained by a simple hypothesis         


Author: Albertito
Date: May 16, 2008 09:39

Flyby anomaly, also called "gravity assist" anomaly,
http://en.wikipedia.org/wiki/Flyby_anomaly
can be easily explained by means of the standard
vectorial addition of velocities, w = u + v, along with
this doppler formula for frequencies, f' = f Exp(-w/c).
The "gravity assist" flyby technique can add or subtract
momentum to increase or decrease the energy of a
spacecraft's orbit. So, if u is the spacecraft's velocity
before flyby, measured in the International Celestial
Reference Frame (ICRF)
http://en.wikipedia.org/wiki/International_Celestial_Reference_Frame
and v is the velocity of the planet, then the vector sum
w = u + v is the new spacecraft's velocity after its flyby.
You only have to plugin w in the above Doppler formula,
and see how the observed frequency can be easily predicted
from...

  "Is General Relativity Compatible With Special Relativity?"

"Is General Relativity Compatible With Special Relativity?"

When the writer first started to investigate General Relativity about
four decades ago, he was quite startled to learn that the results were
incompatible with the Principle of Equivalence and where therefore
incompatible with each other!. Until that point, the writer uncritically
accepted that both theories were completely valid, but this difference
signaled that something was wrong. To clarify, a brief digression would seem
to be in order.

In the late 19th century, the study of Dimensional Analysis was
developed. It was found that all physical relationships (equations) could be
defined in terms of three dimensional entities. Any three...

  Canonical science today, two conferences on cosmology, Newtonian limits, nongeometrical gravity, and scalar 'antigravity'         


Author: Juan R.
Date: May 16, 2008 06:47

I am finishing the draft, titled Newtonian limit difficulties of
General Relativity, where i rigorously showed that General Relativity
has not Newtonian limit. Several mistakes and inconsistencies of the
General Relativity literature are pointed out.

The article would be ready for next week. I will wait for a reply to a
recent communication I have maintained with Eric Poisson just today.

I had an extra delay because the article reproduces Steve Carlip
quotations about Newtonian potentials, boundaries... in one appendix
and i needed to ask permission for copyright issues. Carlip completely
wrong thoughts are presented as typical example of confusion reigning
in *certain* [1] subset of relativistic physics.

I have also showed that difficulties are absent in nongeometrical
theories of gravity as Feynman field theory FTG [2] and R-AAAD. The
source of the difficulties is traced to the geometrical picture of
General Relativity.

This way, General Relativity has lost its status of fundamental theory
of relativistic gravitation, being recovered as approximated
description in a well defined limit of a more fundamental theory.
