Physicists at CERN believe they've found evidence of quantum entanglement in sheep, potentially explaining the near-instantaneous coordination seen in flocks.

The study, by HERD collaboration, used tracking devices and quantum modelling to suggest that sheep may be mentally linked across distances.

Researchers discovered what they call 'moutons', fluffy leptons in the brain that may be behind this bizarre quantum connection.

Though the statistical result reached 4 sigma, it falls short of full scientific confirmation and further testing is required.

The team stresses the findings are serious science, despite the sheep-related puns. If verified, the results could open an entirely new frontier at the intersection of quantum physics and biology and perhaps even explain why some researchers feel inexplicably sleepy near the flock.
