Physicist Rajendra Gupta from the University of Ottawa has completely removed the concept of dark matter from the cosmological equation.

70% of the universe may be made up of this, but we can't even imagine what that might look like. This is the proven dark energy that physics has been trying to understand for a long time. The task is not easy: the object that arouses his curiosity cannot be directly observed with astronomical instruments, it does not emit or absorb any electromagnetic radiation, and its existence can only be inferred through the gravitational influence exerted on visible matter and background radiation.

In the second half of the last century, they began to realize that visible matter represents a very small percentage of the universe, which is why the concepts of dark matter and dark energy were introduced. But not everyone thinks it's good. According to physicist Rajendra Gupta of the University of Ottawa, current models of the universe are wrong about the age of the universe and whether dark matter exists.

the Astrophysical Journal He wrote in his column that the universe may be much older than the 13.8 billion years currently assumed. According to him, this also means that there is no need to rely on dark matter to investigate and understand it.

According to Gupta, the accelerating expansion of the universe in standard cosmology is caused by dark energy, but it is actually due to weak forces of nature, not dark energy.

He believes that if we remove the existence of dark matter from the cosmological equation, this could open new doors in the study of the universe and we could discover new properties of it. For example, the universe is actually twice as old as we think it is now.

For now, Gupta presents his ideas as a theoretical explanation.

The European Space Agency (ESA) launched its Euclid Space Telescope on July 1, 2023, and its main mission is to study dark matter and dark energy. The Hulk recently sent beautiful images back to Earth.
