Modern scientists are entering the testing grounds of a new theory which contests the Theory of Relativity, which is possibly Einstein’s most renowned work.
To put it simple and straightforward, Einstein’s Theory of Relativity states that the speed of light is, was, and will always be the same.
However, modern scientists have come to contradict the universally approved and acknowledged theory.
Back in the 1990’s Joao Magueijo, a theoretical physicist and cosmologist, in collaboration with Niayesh Afshordi, an astrophysicist, came up with their own theory.
According to the two scientists, right after the Big Bang, the presupposed birth of the Universe, the speed of light may have been faster.
This would point out the fact that the speed of light may have not always been constant and as such, comes into a direct contradiction with Einstein’s theory.
The two reached the light speed difference conclusion after studying the cosmic microwave background or the CMB.
A study of the CMB, which are the earliest radiations to have passed through the Universe, revealed erratic or fluctuating density variations.
Further research led to the conclusion that the appearance of these fluctuations was caused or at least contributed to by the possible speed of light variations.
Now, the theory which was first proposed in the late 1990’s has reached a new stage. The researchers have now developed and are ready to test their conclusions.
Magueijo recently released a new prediction, which was based on a model that could determine the primordial speed of light.
As such, they determined that the exact figure of the primordial speed of light spectral index may have been 0.96478.
As the new theory grew and evolved, it can now be tested as it has produced a testable prediction.
The aforementioned Magueijo explained that their theory that the speed of light could and may be variable came across as quite radical.
However, numerical predictions have turned the conclusion from an abstract to an actually testable theory.
If the variability of the speed of light theory is proven to be true, it could potentially cause a chain reaction of events.
The very first would probably lead to modifications of the theory of gravity proposed by Einstein. If his Theory of Relativity would be proven inaccurate, it would lead to future changes in various other currently accepted theories and beliefs.
A new speed of light theory would also come to mean that the laws have also not been constant. As such, they could have been different throughout the Universe’s history or at its beginning.
Afshordi and Magueijo are not the only ones to have shown their excitement towards testing the new theory. Other physicists have expressed their wish to review and test the new conclusions.
A verification of the hypothesis will also probably results in a series of new tests which will be verifying the previously accepted ideas.
This would mean that scientists may be facing a period of physics rewritings as new hypothesis may appear and old ones may be proven false.
The testable fluctuating speed of light theory will be further explained in a paper which is to set to appear in the November 28 issue of the Physical Review journal.
