Is a New Exact Solution to Einstein's Equations Possible?

New antigravity solution will enable space travel near speed of light by the end of this century, he predicts.
On Tuesday, Feb. 14, noted physicist Dr. Franklin Felber will present his new exact solution of Einstein's 90-year-old gravitational field equation to the Space Technology and Applications International Forum (STAIF) in Albuquerque. The solution is the first that accounts for masses moving near the speed of light.

Does anybody know anything about this Dr. Febler or the Advanced Institute at Austin? I can't find a dime to spit on.

I have not taken any physics courses yet, but I do know what is meant by 'exact' (as stated in the title) form my math courses.

Can such a thing as 'exact solution' exist in physics? I am sure it was not Febler's choice for a title, though. I find the use of the term 'anit-gravity' a little bit...uhm, not scientific. Isn't 'anit-gravity' what crackpots and quaks use to highlight their work, not a physicists?

Well, I will say bunko on this one. Even though nothing has been presented as of yet and with my capacity I should not be commenting on such things as this, but I have seen so many other congruent cases.

The Lorentzian, Schwarzschild, Einstein-Rosen (bridge), a "dust" universe and Robertson-Walker metrics are all examples of "exact" solutions to constraints upon general relativity. Even space void of matter and energy might qualify.

My recollection is that Hal Putoff of the Advanced Insitute in Austin studies the controversial "zero-point" energy there, among other speculations.

From the abstract of the first one:

The Schwarzschild solution is used to find the exact relativistic motion of a payload in the gravitational field of a mass moving with constant velocity. At radial approach or recession speeds faster than 3^-1/2 times the speed of light, even a small mass gravitationally repels a payload. At relativistic speeds, a suitable mass can quickly propel a heavy payload from rest nearly to the speed of light with negligible stresses on the payload.

Gravitational repulsion from the Schwartzschild metric?

He looks at an object with angular momentum round a gravitating body, and finds that there's a mysterious repulsive force if he changes the coordinate system. My guess is that he's rediscovered centrifugal force.

Wow if that's true, (havent read it) i'd love to see him present this.

"As you can see this repulsive force must be antigravity"

"Ok, Dr...have you every spun a bucket of water over your head?"

More nonsense from the Hal Putoff Institute of nonsense.
