The problem I see with "subject" is that it's meaningless for defining the group. If you try to create a new group with a different subject, but with the same set of people as are in another group, you'll get kicked back to the old group, which is weird.

Why is there a "to" field?

Yep, but imagine a special relay that anyone can post (with a paid user tag) in it, but only that paid user can download his citations from it with a NIP-42 AUTH.

For DMs, for instance, if you write to me, I will point you to my special relay that will receive your DM and only I can download it.

Yep

I plan to accept a lot of notes from an npub if that npub becomes premium.

Allowing based on a tag is not feasible imo. The npub then has to pay for all the spam that will come his way.. However depending on how much npub wants to pay the equation may change. This is like 1-800 phone numbers I guess. Or like having a big email box without spam filter..

Yeah that's what I can't figure out, I'm able to query the relay and get the event back (using the a tag contents). Amethyst isn't loading the event, even though that same relay is being used by the user and shows connected in Amethyst.

I‘m visiting Threema next Thursday. Tell me if you would like to be hooked up with someone.

Like this?

Sometimes I adjust these values manually, but not always.

Maybe clients should stop mentioning people if these people have not participated in the thread in the last 5 messages, for example.

Olá Vitor. Desinstalei o app ZBD, agora não tem mais nenhum App para zap por aqui. Eu uso LN.tips via Telegram. Agora não existe mais ação. Abraço!

Neutrons don't decay spontaneously. If they did, they would fall apart into free quarks. But the inter-quark forces are so strong that one would need to wait for a time much longer than the lifetime of the universe, or accelerate them in a collider to near-relativistic velocities. What you were probably referring to is beta decay (also known as proton or electron emission) in which a neutron can (doesn't have to) spontaneously turn into a proton-electron pair. This process usually happens in the nuclei of atoms where weak intra-nucleus forces and external perturbations can provide sufficient energy to make this statistically likely. So strictly speaking, it is the nucleus that decays by emitting electrons (or positrons), which unter certain circumstances can render the nucleus unstable (e.g., in super heavy atoms). The conversion is accompanied by the emission of an anti-neutrino (or neutrino), a near-zero-mass particle to conserve the total momentum.

Neutrons don’t have an „outer shell“. They are made of three quarks held together by strong nuclear forces that have a quantum-electrostatic nature. Also, neutrons don’t beta decay, the nucleus does, which emits an electron or positron depending on the emission type.

Ok but its a bit of a stretch to describe it as a shell

I think you mean a nucleus, not a neutron
