Re: Gravitation as a fourth order electromagnetic effect

From Professor Weinberg's writings, we find the following article all
thanks to one of our very own ever faithful posters, Sue.

http://www.aip.org/pt/vol-58/iss-11/p31.html

The professor started out trumpeting "Albert Einstein was certainly
the greatest physicist of the 20th century, and one of the greatest
scientists of all time". He does not know the history very well.
That is understandable because he is a physicist and not a historian.
Later on, he is going to make a few more historic errors.

In the mean time, the professor further went on to describe the
Cosmological constant as the greatest success in any theoretical
scientific development. But without the field equations, it does not
make any sense to talk about the Cosmological constant. So, here are
the field equations.

R_ij - R g_ij / 2 = - k rho g_ij

Where

** R_ij = Ricci tensor, or a 4x4 matrix designed by Levi-Civita to
measure the curvature of space and then spacetime (it was names after
his teacher, Ricci, who years earlier also invented another gage to
characterize the curvature of space now called the Riemann curvature
tensor in which the Ricci tensor and the Riemann tensor are closely
related)

** R = g^ij R_ij = Ricci scalar, designed by Hilbert himself to
measure the curvature in space

** g_ij = The metric, a 4x4 matrix as well

** g^ij = Inverse of g_ij

** k = Constant

** rho = Density of something causing the curvature in spacetime

If rho is assumed to be rest mass per volume, then only rest mass
itself would cause the curvature in spacetime! So, it is very
ridiculous to claim GR dictates that energy manifests a curvature in
spacetime. Notice at this stage GR cannot explain why mass or energy
even causes the curvature in spacetime just like Newtonian law of
gravity cannot explain why mass causes gravitation. Thus, this would
make GR and Newtonian law of gravity on equal terms, or GR is not an
improvement over Newtonian law of gravity except in accuracy if it is
indeed more accurate.

So, where does the Cosmological constant fit in? Since the field
equations are derived by equating the right hand side (now called the
Einstein tensor) with the Poisson equation, it is natural for anyone to
add another term to rho. Although the hindsight is 20/20, anyone may
argue it was Einstein's brilliance to modify the Poisson equation to
allow for the antigravity term. In this case, I am no devil's
advocate to counter the credit to Einstein. However, by modifying rho
it does not limit rest mass as the culprit to cause the curvature in
space. So, what do we have? The field equations become

R_ij - R g_ij / 2 = k (rho0 - rho) g_ij

Where

** rho0 c^2 = Energy density per volume

On top of using manmade gages as the physical foundation to describe
curvature in spacetime, allowing energy to cause the curvature in
spacetime should ring a very loud alarm because both energy and mass
are observer dependent. GR becomes exceedingly silly to have an
observer decide how spacetime is going to be curved. Not all observers
are sorcerers or Henry Porter (maybe Henry Potter, Harry Porter, or
Harry Potter).

The whole exercise can also be achieved by modifying the Newtonian law
of gravity to allow for this antigravity term. So, Einstein's
brilliance in introducing the Cosmological constant is rather lame.
Besides, how were the field equations derived? I am sure it even
eludes the professor, for he thinks it was Einstein's genius that
came up with the field equations. Well, the field equations cannot be
derived from Galileo's or Einstein's versions of Equivalence
principle. Covariant or contra-covariant whatever has nothing to do
with the derivation of the field equations. In fact, the field
equations can only be derived by taking the derivative with respect to
each element of the metric itself of the Einstein-Hilbert Lagrangian.
Who discovered this Lagrangian which does not even qualify as a
Lagrangian? It was none other than Hilbert himself. The probability
for two persons to independently arrive at that BS quantity within a
week of each other is astronomically small, especially given with
Einstein's lack of mathematical skills. Hilbert's
Frankenstein-like Lagrangian is

(k' R + rho c^2) sqrt(-det(g^ij))

Where

** k' = Constant

Hilbert's Lagrangian was designed, patched together from other body
parts, and not derived. By taking the partial derivative with respect
to g^ij, anyone can then get the field equations afterwards in a couple
of steps or less. Notice that there are no Euler-Lagrange equations
involved.

The professor also went on to mention about "Whig History" in which
he seemed to have a good point. However, the new branch of forensic
tool to piece together what happened in history has just been pioneered
by yours truly. In Einstein's 1905 papers on relativity, he or
whoever the author was derived the Lorentz transform from absolute
nonsense. He must have known about the Lorentz transform. That would
very certainly make him a plagiarist. In the longer paper, he hinted
at the following famous equation.

E = m c^2 / sqrt(1 - v^2 / c^2)

On the way to get there, Einstein made a series of gross mistakes.
There is no way in hell that Einstein's thinking would get to that
equation. He must have known the answer somewhere. Again, that would
make him a plagiarist. Some make argue for the very essence of (E = m
c^2) that would eventually leads to atomic bomb. However, if the
energy term is not described by the equation above, there would be no
atomic bomb.

Later on, the professor brought up 5 dimensions of spacetime. The
thought of doing so may be very easy. However, has anyone ever gone
through laying out the Ricci tensor with 4 spatial and 1 temporal
dimensions? I tried it with only 1 spatial and 1 temporal and do not
get simple Newtonian law of gravity. I tried 2 spatial and 1 temporal
in the hope of confining the geodesic in the equatorial plane would
simplify the field equations, but to my surprise, it gave nonsense.
The field equations are indeed designed for 3 spatial and 1 temporal
only. This is so because the field equations are assumed to be
backward compatible with the Poisson equation. The only way to yield
the Poisson equation is allowing 3 and only 3 spatial dimensions. In
another words, only 3 spatial dimensions would produce the Newtonian
law of gravity.

Despite the respectable Nobel prize, the professor's book on GR seems
to have failed as a piece of educational material. As our very own Mr.
Tucker has stared at that book for over three decades, he still has no
clue what Lagrangians are. Well, the whole world seems not to know
what Lagrangians are anyhow with the BS about GR going around.

Back to the subject of history, a few years ago, the professor
published a very short commentary without any scientific value to the
Scientific American magazine. In it, his account of a recent historic
event was fouled up beyond recognition. I was appalled to see a
scientifically oriented magazine would voice any political agendas
without any relationship to science. It was one of the reasons I
decided to quit subscribing to that magazine. In this article, the
professor even praised Einstein as a loyal Zionist. Well, the
professor would be in for a big surprise. Although indeed Einstein
started out as a Zionist, after 1948, he became disillusioned with the
cause. That was one of the reasons why he decided to be reclusive.
Although Einstein was a plagiarist with very low understanding in
physics and piss-poor in mathematical skills, he was deep down a good
moral person. The professor has failed miserably to understand his
idol should really take note here.

And let's end my comment to Professor Weinberg's article with my
great variation on a theme by Baron de Montesquieu, and with comments
mislabeled as a fumble by moortel, I do mean each word I said.

'An empire founded by nonsense has to maintain itself by nonsense.'

Len Gaasenbeek.

This is great. Please allow me to quote from you every now and then.
In the meantime, here is another variation on the theme of Baron de
Montesquieu.

'A hypothesis founded by nonsense through false postulates has to be
maintained and perpetuated with more nonsense and sillier
postulates.'

Koobee Wublee, 2006

The hypotheses that fit into the above saying are none other than SR
and GR themselves.
