Astronomers have obtained an unprecedented set of data on dark energy from observations of more than 4000 supernovae. The new findings could fundamentally change our understanding of the expansion of the Universe and the nature of dark energy, writes SciTechDaily.
Dark energy, which makes up about 70% of all the energy in the universe, remains one of the greatest mysteries of modern physics. It is responsible for the accelerated expansion of the universe, but the mechanism of its action is still not understood. The study of type Ia supernovae, which are standard candles in measuring cosmic distances, allows us to determine the rate of expansion of the universe at different stages of its evolution.
New observations from modern telescopes have provided scientists with the most precise data yet on how the expansion rate of the universe is changing. This information could help test alternative theories of dark energy, including whether it varies over time.
The results of the study have huge implications for cosmology. If they confirm the changing properties of dark energy, it will challenge the Standard Model of cosmology and require new physical theories to explain these phenomena.
Scientists will continue to analyze the data and plan to use future missions, such as the European Space Telescope's Euclid and NASA's Nancy Grace Roman Telescope, to further investigate the nature of dark energy and its role in the formation of the Universe.
