The Felber ‘Antigravity’ Thesis and Cosmology

by | Feb 16, 2006 | Breakthrough Propulsion | 1 comment

Those interested in reading the controversial paper by Franklin Felber recently presented at the STAIF meeting in Albuquerque can find it here. The summary is concise: “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.”

A first reading of the paper reveals an intriguing implication: Felber’s solutions of Einstein’s field equation imply that any mass produces what Felber calls an ‘antigravity field’ above a certain critical velocity. And although this field is at least twice as strong in the direction of motion, the field also repels particles in the opposite direction. It follows, quoting Felber again, that “…a stationary mass will repel masses that are radially receding from it at speeds greater than 3-1/2 c, with obvious cosmological implications.”

Is Felber suggesting a way of explaining Einstein’s cosmological constant, and thus accounting for the apparent acceleration in the universe’s expansion? An intriguing thought, though the equations that express it will demand long and patient scrutiny. Audacious papers make fascinating reading, but the road to experimental verification is unforgiving, as all too many researchers have learned.

  1. Is that a three raised to the one-half power or a three raised to the negative one-half power?

    I’ve decided that trying to produce an inflaton field could be worthwhile, but this certainly seems more practical.

In Centauri Dreams, Paul Gilster looks at peer-reviewed research on deep space exploration, with an eye toward interstellar possibilities. For many years this site coordinated its efforts with the Tau Zero Foundation. It now serves as an independent forum for deep space news and ideas. In the logo above, the leftmost star is Alpha Centauri, a triple system closer than any other star, and a primary target for early interstellar probes. To its right is Beta Centauri (not a part of the Alpha Centauri system), with Beta, Gamma, Delta and Epsilon Crucis, stars in the Southern Cross, visible at the far right (image courtesy of Marco Lorenzi).
