The elusive nature of dark matter particles and their unknown properties have made their detection challenging, but their role in holding galaxies and clusters together is undeniable. However, a new theory proposed by Rajendra Gupta challenges the need for dark matter in explaining the phenomena of the universe.
Gupta’s model suggests that natural forces in the universe weaken over time, offering an alternative explanation for the expansion of the universe and other cosmological phenomena without the need for dark energy. This theory is in contrast to prevailing cosmological theories that rely on unchanged constants of the universe.
By proposing that natural forces weaken over time, Gupta aims to address discrepancies in the standard model of cosmology, such as the seeming rapid growth of early galaxies after the Big Bang. He suggests that by considering an older universe with changing natural constants, the need for dark matter diminishes.
The concept of “tired light” first proposed by Swiss astrophysicist Fritz Zwicky in the 1920s is revisited in Gupta’s theory, suggesting that the redshift of light from distant objects could be due to the gradual loss of energy as light travels through space. While this challenges the prevailing dark matter hypothesis, some physicists like Matti Heikinheimo remain skeptical and point out that alternative theories often focus on specific observations while ignoring others that support the existence of dark matter.
In conclusion, while Gupta’s alternative theory offers a different perspective on the role of dark matter in cosmology, further research and observations are needed to fully understand the nature of
