Academians from the University of Nottingham have suggested that an invisible space wall formed by hypotetical symmetrirons pushing the fifth force may shed light on the origin of the Universe.
It’s never easy to shed light on the Universe’s origins. Researchers, on the other hand, aren’t sitting on their hands; two scientists recently proposed the presence of a new “fifth force” in space.
The “fifth force” could put the Lambda cold dark matter (CDM) scenario, which is associated to the origin of the Universe, to the test.
Two University of Nottingham academics claimed that hypothetical particles known as symmetrons may push the “fifth force” to construct “domain walls,” or unseen borders in space, in a paper that has yet to be peer-reviewed.
“We know that we need new particles because we have dark matter and dark energy and so we suspect that we’re going to need to add new particles to our standard model to account for those things,” says the researcher. Vice quoted Aneesh Naik, a research fellow at the University of Nottingham and the study’s lead author.

“That’s the context in which people study theories like symmetron theory — it’s a new particle candidate for dark energy and/or dark matter,” the researcher explains.
Albert Einstein’s cosmological constant, a variable that explains his general relativity equations, is one of three main components of the standard model. Cold dark matter, which comprises of slow-moving particles that do not release radiation, and conventional matter, which humans interact with every day, are the other two components.
Given that symmetrons have been proposed to fill in some of the missing connections in order to help explain the presence of dark matter and dark energy, a phenomenon that appears to be causing the Universe to expand at an accelerated rate, the Nottingham-based hypothesis could revolutionize the CDM model.
Smaller galaxies should be trapped by the gravitational pull of larger host galaxies and thrown into chaotic orbits, according to standard theory, but this has yet to be proven in real-world data, which the two scientists’ research may help to explain. According to the researchers, unseen boundaries between symmetron particles could cause smaller galaxies to form disks around much larger hosts.
Many others, however, are waiting for definitive proof of symmetrons’ existence, with advanced space devices like the James Webb telescope, which is now helping scientists examine areas of the early cosmos, likely to confirm the theory.
