That is not possible without adding external mass to the earth, in enormous amounts -- you have quintupled the mass of the earth in 5 seconds. If such an outrageous thing is happening you should mention it up front.


Using AE's law G_uv=k*T_uv we would find,
Guv at (t=5) = 5*Guv at (t=1) and
Tuv at (t=5) = 5* Tuv at (t=1).

Not true. You forget that Tuv is the energy-momentum tensor, and during that enormous influx of matter the {Tuv} have a different structure than when there is no such influx (before t=1 and after t=5).

The {Tuv} are the COMPONENTS OF A TENSOR and not simply real values as you seem to assume. In particular: in this situation T_00 is proportional to the current mass density of the earth, increasing 5 times as you say; but the T_0i are related to the rate of matter influx, which is constant (not increasing 5 times are you assume); the T_ij are related to the stress induced by all that influx of matter which is different still (here i and j range from 1 to 3 and represent spatial components)....

	launchpad, inside the earth. At the rocket itself, T_uv
	just corresponds to the rocket itself, which is unchanged
	by the great modification of the earth. Though I have no

	it....


Normally GRist's use G_uv=0 and Schwart's Solution, [...]

Obviously you have no idea how GR is normally done. In particular, "GRists" use G_uv=0 _ONLY_ when T_uv=0. In your case there is an ENORMOUS influx of matter and T_uv is clearly not zero in any region near the earth.


T_uv;w =0   ,however,
T_uv;w  is not a constant.

Do you really think that 0 is not a constant? Don't you ever read what you write???


Physically, we're incrementing the energy in
a volume of spacetime by inducing a quanta
of energy like a photon, or perhaps emitting,
as the spacecraft is deformed, and from various
refs, that constant is relativistic.


That's just word salad posturing as something worth saying.
