Bedtime Astronomy

For decades, the Bullet Cluster has been considered one of the strongest pieces of evidence for dark matter. But new observations are reviving an alternative possibility: what if our understanding of gravity is incomplete?

As fresh data challenge long-standing assumptions, scientists are once again debating whether the universe is shaped by invisible matter or by laws of physics we have yet to fully understand.

A distant galaxy with nine nearly perfect rings is forcing scientists to rethink one of astronomy’s biggest mysteries.

While such structures are usually linked to colossal cosmic collisions, a new theory points to something far more intriguing: dark matter itself. If correct, the Bullseye galaxy could provide rare clues about the hidden substance that dominates the universe and reveal that its influence is far stranger than previously imagined.
