Summary
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.
