Universe is 2 times older and has no dark matter, says a new study

A new study claims that dark matter does not exist and never has existed, upending the standard cosmological model, reports sciencealert.com.

Last year, Canadian theoretical physicist Rajendra Gupta presented a theory that our Universe is actually 26.7 billion years old, not 13.8 billion years old, as is commonly believed.

The physicist’s new research, published in The Astrophysical Journal, confirms past results, but now the scientist says that dark matter does not actually exist and never has existed.

A new theory by a Canadian physicist suggests that one of the important components of our Universe is, in fact, an unnecessary component, and may not exist at all. This theory challenges current understanding of the universe and calls into question the reliability of the standard model of cosmology.

A Canadian physicist says the results of a new study confirm that the Universe is actually 2 times older, meaning it is not 13.8 billion years old, but 26.7 billion years old. He also says that the universe does not need dark matter to exist.

We remind you that according to the standard cosmological model, dark matter is a substance that does not interact with light, but is essential for the evolution of the Universe. Many observations indicate that dark matter exists. According to Gupta, his results indicate otherwise, but it is consistent with observations of space.

One of the problems in astronomy is that scientists see very distant galaxies in the early Universe that appear quite mature for such an early period in cosmic history and are very massive. This means that perhaps the standard model of cosmology is not correct, or that the Universe has actually existed much longer than is commonly believed.

While current cosmological models assume that certain forces governing the interaction of particles remain constant over time, Gupta believes that they change and this affects the behavior of light, which, traveling vast distances, loses its energy. Scientists believe that the expansion of the Universe comes not because of dark energy, but because the driving forces of the Universe weaken over time.

Gupta bases his conclusions that the Universe does not need dark matter to exist on a model that combines two theories about the cosmos – covariance constants and aging light.

The first concerns the principles of physics regarding how much force is needed to force particles to interact and how those forces weaken over time. The second concerns the nature of light and how it changes with distance as it travels through space. This aging light, according to the theory, could explain redshift, or the reddening of light from very distant objects, by light losing its energy over time.

It has long been thought that the redshift is caused by dark matter and dark energy, that is, the expansion of space stretches the wavelengths of light into the reddest part of the spectrum.

According to the Canadian physicist’s theory, the redshift is caused by a weaker constant force as the universe expands, with a weaker force allowing the universe to expand faster.

At the same time, the physicist believes that his theory works if we abandon the idea of ​​the existence of dark matter in the Universe. Based on this, the physicist suggests that the standard model of cosmology is imperfect and a new one is needed. But this theory still needs more reliable confirmation with the help of new observations of space.
