A new paper in the Journal of Cosmology and Astroparticle Physics has put forth an intriguing theory: A so-far unexplainable neutrino could have been blasted at Earth by a cosmic particle accelerator known as a "blazer."
But let's back up.
For a while now, we've been reporting on a watershed 2023 neutrino detection that left physicists scratching their heads. Seen on a neutrino detector housed at the bottom of the Mediterranean Sea, this particle, so elusive it's often called a "ghost particle," carried far more energy than had ever been predicted for its type.
The detection immediately required an explanation and generated considerable speculation. Now, a few years on from the original detection, we're finally seeing this conversation turn into some peer-reviewed papers on the subject.
A few months ago, we saw a study detailing...
