The present theoretical model for the composition of the universe is that it’s fabricated from ‘normal matter,’ ‘dark energy’ and ‘dark matter.’ A brand new uOttawa study challenges this.
A University of Ottawa study published today challenges the present model of the universe by showing that, actually, it has no room for dark matter.
In cosmology, the term “dark matter” describes all that appears to not interact with light or the electromagnetic field, or that may only be explained through gravitational force. We won’t see it, nor will we know what it’s fabricated from, however it helps us understand how galaxies, planets and stars behave.
Rajendra Gupta, a physics professor on the Faculty of Science, used a mix of the covarying coupling constants (CCC) and “drained light” (TL) theories (the CCC+TL model) to succeed in this conclusion. This model combines two ideas — about how the forces of nature decrease over cosmic time and about light losing energy when it travels an extended distance. It has been tested and has been shown to match up with several observations, reminiscent of about how galaxies are unfolded and the way light from the early universe has evolved.
This discovery challenges the prevailing understanding of the universe, which suggests that roughly 27% of it consists of dark matter and lower than 5% of peculiar matter, remaining being the dark energy.
Difficult the necessity for dark matter within the universe
“The study’s findings confirm that our previous work (“JWST early Universe observations and ΛCDM cosmology”) in regards to the age of the universe being 26.7billionyears has allowed us to find that the universe doesn’t require dark matter to exist,” explains Gupta. “In standard cosmology, the accelerated expansion of the universe is claimed to be attributable to dark energy but is actually as a result of the weakening forces of nature because it expands, not as a result of dark energy.”
“Redshifts” check with when light is shifted toward the red a part of the spectrum. The researcher analyzed data from recent papers on the distribution of galaxies at low redshifts and the angular size of the sound horizon within the literature at high redshift.
“There are several papers that query the existence of dark matter, but mine is the primary one, to my knowledge, that eliminates its cosmological existence while being consistent with key cosmological observations that we’ve got had time to verify,” says Gupta.
By difficult the necessity for dark matter within the universe and providing evidence for a brand new cosmological model, this study opens up latest avenues for exploring the elemental properties of the universe.
