A new investigation of the early Universe led by Poland’s National Centre for Nuclear Research has just found that there may be an interaction between two of the most elusive components of the cosmos.

By combining different kinds of observations, cosmologists have shown that what we see is more easily explained if neutrinos, aka ‘ghost particles’, weakly interact with dark matter.

With a vexing certainty of three sigma, the signal isn’t strong enough to be definitive, but is also too strong to be a mere hint or noise in the data.
