Mini "Neutron Star" discovered

Mini "Neutron Star" discovered? Well, maybe not! But quite an eye-catching
result anyway? Basically a "Tetra-neutron" (resonance) existing for 4x10-22s! 🥳

The idea of a BEAM of "Helium 8" (with a lifetime 100ms) is quite fun too?
That its geometrical arrangement of protons & neutrons can be studied etc. 😎

What? Neutrons having a memory!

Indeed, I wonder what relevance this has to neutron stars, though of course in those extreme situations the neutrons don't appear to have any option but to get close to one another.

Never entirely sure on that one either, but! 😏
