Scientists are gaining insight into dark energy, a mysterious force making up nearly 70% of the universe. It’s pushing stars and galaxies away from each other at an ever faster rate. Recent findings suggest that dark energy may be weakening, which could have significant implications for our understanding of the universe.
The Dark Energy Spectroscopic Instrument collaboration has released data on 15 million galaxies and quasars, showing a decrease in its strength over time. This contradicts previous assumptions that dark energy is constant. The research aims to map around 50 million galaxies by 2026, but more work is needed for conclusive evidence.
If dark energy continues to weaken, the universe may eventually stop expanding and collapse in on itself, known as the Big Crunch. While this fate may seem bleak, it offers closure, according to some scientists. The possibility of the universe ending raises questions about its significance and meaning.
