Dear New York Times

In the write-up (“With faint chirp, scientists prove Einstein correct”, p. A1, 2/12/16) we study that black holes were part of Einstein’s theory. The reality is quite different. “Einstein argued vigorously against black holes [as] incompatible with reality” (see “Black Holes” by R. Anderson) and his rivals held back their acceptance for many years.

Einstein was also mistaken when he rejected Quantum Field Theory. According to his biographer A. Pais,” QFT was repugnant to him”. This is ironic because QFT, and only QFT, reveals and resolves the paradoxes of Relativity and Quantum Mechanics that most people struggle with (see “Fields of Color: The theory that escaped Einstein” by this writer).

Quite possibly the most significant irony is the statement, “according to Einstein’s theory, gravity is caused by objects warping space and time”. While that is what everybody accepts today, the truth is that Einstein recognized gravity as a force field, similar to electromagnetic fields, except that it is produced by mass, not charge. That an oscillating mass generates gravitational waves is no more incomprehensible or unexpected than that electromagnetic waves are produced when electrons move back and forth in an antenna. To Einstein, curvature was actually a consequential result, similar to the changes in space and time produced by motion according to his Special theory of Relativity.

Black holes. Contrary to many studies, black holes were actually not part of Einstein’s supposition. In fact Einstein argued strongly against black holes [as] incompatible with reality, and his opposition held back their approval for many years.

Synopsis. Gravitational waves are easy to understand if you accept gravity as a force field, similar to the electromagnetic field (QFT). And while the contraction effect is more subtle, it is not that much different from the F-L contraction that has been accepted for over a hundred years.

GRAVITATIONAL WAVES REVEALED

By Rodney A. Brooks
author of “Fields of Color: The Theory That Escaped Einstein”.

The recent discovery of gravitational waves at LIGO (Laser Interferometer Gravitational-Wave Observatory) has captured the mind of the public. It will stand as one of the great accomplishments of experimental physics, in addition to the famous Michelson-Morley experiment of 1887 which it resembles. In fact by comparing these two experiments, you will see that understanding gravitational waves is not as difficult as you believe.

Contraction. Michaelson and Morley measured the speed of light at different times as the earth moved around its orbit. To their – and everyone’s – surprise, the speed turned out to be continuous, separate of the earth’s motion. This breakthrough caused great consternation until George FitzGerald and Hendrick Lorentz came up with the sole feasible explanation: objects in motion compress. Einstein then showed that this contraction is a consequence of his Principles of Relativity, but without saying why they contract (other than a need to conform to his Principles). In fact Lorentz had previously provided a partial explanation by showing that motion affects the way the electromagnetic field interacts with charges, causing objects to contract. However it wasn’t until Quantum Field Theory came along that a full explanation was found. In QFT, at least in Julian Schwinger’s model, everything is made of fields, even space itself, and motion affects the way all fields interact.

Waves. Electromagnetic waves, e.g., radio waves, have long been recognized and accepted as a natural phenomenon of fields. Now in QFT gravity is a field and, just as an oscillating electron in an antenna sends out radio waves, so a substantial mass moving back and forth will send out gravitational waves. But it didn’t take QFT to show this. Einstein also believed that gravity is a field that obeys his equations, just as the EM field obeys the equations of James Maxwell. In fact gravitational waves have been accepted by many physicists, from Einstein on down, who see gravity as a field.

Curvature. But what about “curvature of space-time”, which many people today say is what produces gravity? You may be shocked to learn that’s not how Einstein saw it. He believed that the gravitational field triggers things, even space itself, to contract, comparable to the way motion causes contraction. In fact Einstein used this analogy to show the correlation between motion-induced and gravity-induced contraction: they both affect the way fields work together. It is this gravity-induced contraction that is sometimes knowned as “curvature”.

Evidence. The first detection of gravitational waves was done at LIGO, using an apparatus similar to Michelson’s and Morley’s. In both experiments the time for light to travel along two perpendicular paths was examined, but because the gravitational field is much weaker than the EM field, the distances in the LIGO apparatus are much greater (miles instead of inches). Another difference is that while Michelson, not knowing about motion-induced contraction, anticipated to see a shift (and found none), the LIGO staff used the known gravity-induced contraction to view an alteration when a gravitational wave passed through.

Fields of Color: The theory that escaped Einstein explains Quantum Field Theory to a lay audience, without any math.
