Suppose this allien mathematical genius arrives to earth and he is
presented with the GR equations. He knows nothing about Newtonian
physics, he oes not know what force means for earthlinks, he has never
seen F = dp/dt, or F =ma or, F = GMm/r^2

He is asked to find out what are the equations of motion in the weak
field limit.

Will he be able to derive Newton's laws of motion and universal law of
graviation in the weak field limit from the GR equations?

Yes.

The one I spoke to told me NO, a flat NO.

OK, I don't know what you expect me to do with that.

Now, I'm sure you know you're asking a hypothetical question, since
there are no real aliens in this position and there are no real
earthly physicists in this position.

Ask him/her/it to write down for you where the wiggle room is. Then

There are an infinite number of solutions to the field equations. In
vacuum, one such solution can be the following.

ds^2 = G c^2 dt^2 / (1 + r / K) – K^4 (1 + r / K) dr^2 / r^4
– K^2 (1 + K / r)^2 dO^2

Where

** G = Dimensionless constant
** K = Constant of length
** dO^2 = r^2 cos^2(Latitude) dLongitude^2 + r^2 dLatitude^2

It is static and spherically symmetric. However, it is not
asymptotically flat. Nevertheless, it is still a valid solution.

Does it degenerate into Newtonian law of gravity? No.

Therefore, Mike is correct on this one. Both Professor Draper and Mr.
Bielawski are very wrong. It is time for both gentlemen to propose a
graceful retreat.

Yes, gracefully retreat from the cranks who confuse persistence of
lies with facts.

To me and to many people I know, a crank and an imbecile, is a person
who while it insists GR is a correct theory of gravitation, he thinks
that a = GM/r^2 is and ordinary differential equation. Such a crank
exists and is called Eric Gisse as these posts proves beyond any
doubt:

http://groups.google.gr/group/sci.ph...b?dmode=source

Eric Gisse's excuse for not being able to sove a simple mechanics
problem: "One of these days I'll stop posting on groups when I'm sleep
deprived."

http://groups.google.gr/group/sci.ph...8?dmode=source

Now, who is the crank here?

Mike
