This is the best summary I could come up with:
Somehow, neutrinos went from just another random particle to becoming tiny monsters that require multi-billion-dollar facilities to understand.
And there’s just enough mystery surrounding them that we feel compelled to build those facilities since neutrinos might just tear apart the entire particle physics community at the seams.
As a result of this process, known as beta decay, the nucleus also emits an electron or its antimatter partner, the positron.
But even with the multitude of decays with energies great and small happening all across the Universe every single second, the elusive nature of neutrinos meant we could only occasionally, rarely, weakly see them.
The other two generations share the same properties (like spin and electric charge) but have a heavier mass.
Aside from the burning mystery of the existence of particle generations in the first place, it would be a bit greedy for one neutrino to participate in all possible reactions.
