A paradox that prevents us from measuring the expansion of the universe

The study of how the universe is expanding has been a central area of ​​modern cosmology for decades. Within that, the Hubble constant, a parameter that describes the way this expansion occurs, stands as a fundamental pillar. This is a factor established by a famous astronomer Edwin Hubble In the 19th century, it referred to the apparent speed at which distant galaxies are receding. Expansion: This is a very important part to measure and measure the rate of expansion of space.

However, over the years, the precise measurement of the Hubble constant has evolved with technological advances and new observational techniques. This has allowed us to have more accurate data showing the specifics Contradiction In determining the constant according to the method used to calculate it. This contradiction “Hubble voltage” and has sparked enormous debate in the scientific community, posing major challenges to understanding the processes governing the expansion of the universe.

The Hubble Constant

The approach of a single constant representing the rate of expansion of the universe began to take shape in the minds of the scientific community. First decades of the 20th century. During that period, the understanding of the cosmos underwent a major change, as pioneering observations of distant galaxies showed the first signs of expansion. Changed the view of the universe Fixed.
