In his seminal work on the general theory of relativity, published in 1915, Albert Einstein—who is regarded as the greatest modern scientist after Isaac Newton—postulated that gravity was responsible for the curvature of space-time.
The 1919 solar eclipse served as the first test of this, demonstrating how starlight twisted as it passed the Sun. This was discovered while Mercury was precessioning, or rotating around the Sun. Over the years, observations of astronomical phenomena have provided a number of additional confirmations. Dark Energy Spectroscopic Instrument (DESI) observations at Kitt Peak National Laboratory in Arizona, USA, provided the most recent data. At the same time, the observations covered 5,000 galaxies.
The findings showed that the presence of gravitation as a force holding galaxies together led to the formation of their structures, including clusters of galaxies and super-clusters. The scientists conducting the study made this announcement on Tuesday.
Galaxies make up one-fifth of the universe’s structure, which dates back 13.8 billion years after the Big Bang. In other words, almost 11 billion years ago. However, the DESI researchers discovered that the dark energy propelling the universe’s expansion is a dynamic force. As a result, it is impossible to claim that the cosmos will keep expanding.
