Dark matter does not exist, the standard model must be replaced, says scientist

Dark matter, the mysterious substance long thought to be one of the most important building blocks of the universe, may actually be completely unnecessary and, in fact, may not exist at all, according to a new study.

The study’s findings were published in the peer-reviewed academic journal. The Astrophysical Magazine.

The results of this study challenge our understanding of the universe and cast doubt on long-held scientific knowledge about its structure.

Nothing really (dark) matters: our tenuous understanding of the universe has been shattered

First, it is important to understand exactly what dark matter it actually is, or rather, what we thought it was, assuming this study is correct and does not exist at all.

Dark matter is assumed to be an invisible substance that does not emit light and makes up more than 85% of the matter in the observable universe.

Furthermore, it is assumed to be vital for the continued evolution of the universe, as stipulated by the standard model of cosmology.

But if it is invisible, how did scientists know there is so much dark matter and how important it is supposed to be to the universe?

The answer is gravity. Gravity as we know it is explained by Albert Einstein’s theory of general relativity. It is often thought that everything that cannot be explained is due to the influence of dark matter.

An example of this is the rotation of galaxies. When a spiral galaxy rotates around the galactic center, science dictates that rotation speeds will decrease the farther something is from the center. But that doesn’t happen. Instead, everything remains flat, without slowing down.

Without breaking the laws of physics, this would have been possible if there was a lot of matter within the galaxy that simply could not be seen. That would change mass distribution.

We also see it with gravitational lenses, when something is so massive that it bends light around it with its gravity, allowing scientists to see things that should be blocked out. Gravitational lensing should be able to help infer how much mass something has, which can therefore help infer how much dark matter is in a given galaxy, even if we can’t see it.

Overall, there is an enormous wealth of academic literature on the topic of dark matter, which attests with certainty to its existence and importance.

But this study, written entirely by Professor Rajendra Gupta, changes everything by boldly suggesting another alternative: there is no dark matter and there can be no dark matter.

“There are several papers that question the existence of dark matter, but mine is the first, to my knowledge, that eliminates its cosmological existence and at the same time is consistent with key cosmological observations that we have had time to confirm,” he said in a release. .

If dark matter is supposed to be so important and there is so much evidence for its existence, how could Gupta apparently disprove it?

The answer lies in a model that combines two theories about the cosmos, covariant coupling constants and tired light.

The first of these refers to a physics principle about how much force is needed in an interaction and how those forces decrease over time. Tired light is something that seeks to address the nature of light and distance, suggesting that light appears to lose energy over time as it flies through space due to collision with other objects or particles. This was an explanation for the redshift, which is why objects far away in space appear redder in proportion to their distance.

This is how this model works.

Redshift is part of the expansion of the universe, since the further away something moves, the redder it becomes. It has long been believed that this expansion was due to dark matter and energy. The existence of dark energy itself would be the answer to the mystery of how the universe expands and how the expansion accelerates.

According to this model, it would be caused by the constant weakening of the coupling as the universe expands, and the weakening force would allow it to expand faster.

With this in mind, Gupta’s study appears to be consistent with previous literature on cosmology, such as the evolution of light over time and the scattering of galaxies.

However, this is just an oversimplified summary of a complex academic work. The study covers everything from star formation, the sound horizon, cosmic microwave background radiation and more. He even proposes to have solved the impossible mystery of the first galaxies, when galaxies were discovered in the early days of the universe that should not have been able to exist. It also reaffirms previous research that indicated that the universe is approximately twice as old as we thought.

The study is not perfect. After all, scientists have long ignored the tired theory of light as outside science. However, the research remains strong.

At the very least, it highlights an obvious point: the standard model of cosmology is flawed and we need a new one.

With new technology available that may allow us to study space like never before, perhaps there is a new model on the horizon.
