The speed of light may vary and be slower than gravity!

If you know a little about physics, you know that this is a very complex and perhaps fascinating area of ​​science. One of the great names of this science is Albert Einstein, who helped to ground some important concepts for the study of modern physics. It was Einstein who explained the theory of relativity, and he also said that nothing can travel faster than light.

The big question raised by University of Massachusetts physicist John Donoghue is that the notion of spacetime in 4D, as Einstein theorized, would only be noticeable on a large scale. It's as if you calculated the speed of a soccer ball, but you forget that the soccer ball is made by atoms that are also in motion, but in different proportions and rhythms.

Inconstant?

This view proposed by Donoghue may cause physics to undergo considerable changes and have to adapt to the concept that the speed of light may not be constant. In an article published on the Technological Innovation portal, the physicist admits that this change "would really change 99.9 percent of research in physics."

The big problem here is to tune the calculations of large and small scales to the concepts of general relativity proposed by Einstein. This causes the speed of light, for example, to fail to conform to a pattern when analyzed in both situations.

Light and gravity

This was observed after Donoghue and the University of Toronto scientist Mohamed Anbar proved that the speed of light can vary with varying energy.

Scientists around the world believe it is necessary to adopt new perspectives. This view of Donoghue, which intends to evaluate velocity according to different scales, implies that the velocity of gravity may be greater than that of light, and not identical, as is normally considered by physics.

Science will only know these values ​​accurately when it detects the components of invisible gravitational waves, which are ripples present in the spacetime set. Until then, we have the question: was Einstein wrong?
