One of the biggest riddles in physics might have found a new angle. Scientists experimenting with the “Cosmic Memory Hypothesis” are trying to figure out if the universe could be a bearer of memory of past things, which may be a key to understanding dark matter. It’s a crazy dreamy idea but physicists who are working on it are even more open-minded as they try to come up with a solution for these age-old questions that keep puzzling science.
Dark matter is the greatest challenge in understanding the universe. Scientists figure that since matter made out of what people know and are able to see (stars planets galaxies…) forms only a small part of the entire universe, most of it is actually made of dark matter and dark energy, that people cannot see directly but only through their gravitational effects.
The more advanced experiments and attempts to detect these particles have been to no avail. Scientists are sure about the existence of dark matter because the galactic rotation rates indicate there must be more mass exerting gravitational pull than the galaxies’ surfaces can explain. In fact, no galaxies would have survived if there hadn’t been the additional pull. That’s why, astronomers think that the dark matter supply is the one that holds galaxies together.
The Cosmic Memory Hypothesis starts to tackle this topic in an even stranger way. Instead of searching for a new particle, they try finding out which reflection the very nature of the three-dimensional extensional space – (space-time)- stores of all the physical interactions that took place in it. That is, it is a theory that the universe having a form of “memory” which affects how matter and gravity behave over large distances and long periods of time, is possible.
The physicists are coming up with the idea being motivated by discussions on how the universe keeps the information and on the certainty that it never gets lost. Really, if some form of information exists after death, it would be quite natural to think that events in the universe leave their marks and continue to have an influence.
In the supports’ view, there is a possibility that the so called effects are the result of a cosmic memory First and However these occurrences become the reason of the gravitation attributed to the effect of the dark matter. It would be a totally different way of thinking that instead of dark matter, gravity comes from the information imprinted in the space-time itself. It is not that one cannot speak about the existence of dark matter but there is a chance here to have a different perspective about the events observed in the universe.
It is a theory without a solid basis and many the scientists say that there would have to be great proofs for it to even be considered that it can go against the dark matter models that exist today. Then again, deepening our understanding theoretically is very much a part of science. After all, pretty much all the discoveries in physics started with a first idea that was so out there that most people thought it was crazy.
With the idea of cosmic memory and gravity as the two hands, the proponents go on. The greatest chunks of the universe have been described by Einstein’s theory of general relativity. The theory makes gravity nothing more than the bending of four-dimensional space by masses and energies. It is the hypothesis of Cosmic Memory that reminds us that the information that has been stored through ages in this( Einstein’s) picture of the universe could have been influencing gravity changes in such a subtle way that actually, the changes in the gravity were unaccounted for by the very models that we have.
