“Sagnac Revisited” was the original project name when the FECORE website was first published. Our site explained the original Sagnac experiment and suggested it be reproduced using current technology.

Since then, we’ve added an updated Sagnac project proposal. This update was based upon research conducted at St. Cloud University in Saint Cloud, Minnesota (United States) in 2003. In his research Dr. Yi Zheng and his team conducted moving linear light tests and concluded the so-called Sagnac Effect occurred in inertial frames of reference, as well as in a rotational reference frame. This further provided evidence that the correct conclusions were drawn from Sagnac’s experiment more than a century ago.

During FECORE’s research for the updated Sagnac proposal, we found supplies for the experiment are readily available at a relatively modest price. Thanks to the generous support by a corporate sponsor (who wishes to remain anonymous) both the reproduction of the Sagnac experiment and the St. Cloud experiments will move forward.

For those who have not previously read the Sagnac project plan, we will provide the background here:

In 1887, the Michelson-Morley experiment was conducted to observe and measure if there were changes to the speed of light depending upon which direction the light propagated relative to the aether. This was achieved by splitting a beam of light and directing one half in an east, then west direction; and the other half in a north, then south direction.

Michelson and Morley assumed the earth was traveling in a large orbit around the sun at 67,000 mph. They theorized the aether did not move with the earth’s orbit but that the earth moved through the aether. Therefore, light propagating along an east-west direction would encounter the aether in a different manner than light propagating in a north-south direction. And further, that the difference of the light’s direction in the aether should be observable by different speed of the two halves of the split beam. This difference in speed would then be detected via an interference pattern produced when the beams were recombined – one beam being out of phase from the other due to the different travel times.

But the test detected no significant difference between the two halves of the beam. Both beams made the trip during the same time span. What Michelson and Morley failed to do was question their baseline assumption, which was that the earth moved around the sun. So, the experiment essentially was looking for a way to explain observations without questioning the heliocentric model.

Albert Michelson was a 34-year-old famous scientist at the time of the experiment. Although he grew up in a mining town on the California-Nevada border, he moved in powerful circles. Michelson was appointed by President Ulysses S. Grant to the Naval Academy and married the daughter of a wealthy Wall Street banker. The experiment’s failure became a well-known embarrassment.

Help came when a previously unknown patent clerk by the name of Albert Einstein published three papers in 1905 relating to what is known as “The Special Theory of Relativity.” Proponents of heliocentric spinning earth now had a way to explain the “failure” of the Michelson-Morley experiment. Einstein claimed there was no medium through which light waves propagate. This idea was used to explain why the Michelson-Morley experiment detected no motion of the earth through space by concluding there is no aether!

In 1907, after Einstein’s writings had erased the embarrassment, Michelson was awarded the Nobel Prize for his science work. Naturally, by saving the heliocentric model with this conclusion, Einstein’s papers were given wide coverage. But Georges Sagnac and many other scientists were not convinced.

Sagnac then performed his experiment in 1913 by splitting a beam of light and sending it in different directions much like Michelson and Morley had done. But in his experiment, Sagnac measured the two beams interference patterns both in a stationary setting and then in a known-moving reference frame by rotating the entire apparatus.

The results provided convincing evidence of the existence of the aether – that light moves at different speeds depending upon the speed of the source or the target. Sagnac maintained he had refuted Einstein’s theories. However, current mainstream science discounted Sagnac’s work by claiming the results were only an effect of rotational motion and would not be present in an inertial or linear non-accelerating motion.

Now, FECORE plans to recreate the Sagnac rotating table and duplicate the more recent St. Cloud moving linear light tests, as well. FECORE has been in contact with Dr. Yi Zheng and he’s pledged his support as we proceed.
