Neutrino Asymmetry Passes Critical Threshold

So... would this mean neutrinos are for sure not Majorana fermions? Because you&#x27;d think that a particle couldn&#x27;t be its own anti-particle if it&#x27;s anti-particle has different properties, but quantum mechanics has surprised me before.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Majorana_fermion" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Majorana_fermion</a>

&gt; ...further explaining why anything at all exists today, since matter and antimatter in equal portions would have mutually annihilated.<p>Shouldn&#x27;t this read &#x27;how&#x27; instead of why? I am far from an academic so please enlighten me. I presume &#x27;why&#x27; to question reason and &#x27;how&#x27; to explain means.

That 12 story tank looks amazing.

Would this also imply that even today new mass could be created? Similar to how Hawking Radiation assumes virtual matter&#x2F;antimatter pairs getting created all the time would it be plausible for neutrinos and their antimatter counterparts to pop into existence without fully annihilating each other?

A question to particle physicists: I&#x27;ve always thought that matter and anti-matter qualifications applied only to charged particles. Neutrinos have no charge, so how can it have an antiparticle? Does there exist an &quot;anti-neutron&quot; as well?

How does this square with the idea that antiparticles are particles traveling backwards in time?
