There are an infinite number of solutions to the field equations. In

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

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.


Another solution that is static, spherically symmetric, and (this
time) asymptotically flat is the following.

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


It's the same solution as Schwarzschild's, you merely changed the
numbers labelling the spheres of symmetry.

Does is degenerate into Newtonian law of gravity? No, because it
follows an inverse-cubed law instead of the inverse squared law.


I think you meant "inverse-Koobeed" (you knew I'd write that!) Anyway,
since you reshuffled the numbers labelling the events, obviously you
get a different expression wrt those labels. Using the same method, I
can define an electrostatic force that's inversely proportional to the
17th power of the coordinate. This sort of manipulations is just name-
changing and as such it obviously has no influence on the physics.

The
Einstein field equations represent an utter nonsense. They suit for
the ones to promote mysticism as wisdom. shrug


You've said that before. It's wrong.
