In space, there are many mysteries, one of which has revealed a secret to scientists. They managed to track how the structure of the universe has evolved over the past 11 billion years.
As reported by Reuters, this is currently the most accurate study of gravitational behavior on a vast scale. It aligns with the principles of Albert Einstein's theory of relativity, confirming the idea he proposed in 1915.
The research spanned many years, focusing on dark energy, which accelerates the expansion of the universe. Researchers utilized a year of observations from the Dark Energy Spectroscopic Instrument (DESI) at the Kitt Peak National Observatory in Arizona, which can capture light from 5,000 galaxies simultaneously. In this study, scientists analyzed data from nearly 6 million galaxies and their luminous cores dating back 11 billion years.
Einstein believed that the concentration of mass and energy distorts the fabric of space-time, affecting the motion of everything passing nearby. Recently, scientists speculated that the accelerating expansion of the universe might lead to a revision of the theory; however, the research findings indicated that gravity behaves as Einstein had anticipated.
The study suggests that dark energy may not be a constant force, but rather a dynamic one. Scientists propose that it could weaken over time. The physical nature of dark matter remains a mystery.
