Researchers thought that the density of dark energy has remained the same since the universe's birth, but the data from the Dark Energy Spectroscopic Instrument (DESI) seemingly suggests otherwise.
DESI could have discovered something unique. As its name implies, DESI is a tool for studying the properties of dark energy, an enigmatic substance that makes up 68% of the universe's energy and pushes space apart in a manner opposite to gravity.
Until now, scientists have assumed that the density of dark energy has remained constant since the universe began 13.7 billion years ago, even though they are unsure of its exact nature. However, DESI's first findings imply that this presumption might not have been accurate. Scientists at DESI speculate that dark energy's density may have been shifting over time.
Dragan Huterer from the University of Michigan, who worked on the project, found the findings strange. He added that cosmology would be thrown into disarray should the results hold true.
