Just a quick question; Why does this Heisenberg incertitude, ΔEΔt Exists, if time is not considerate as an observable ?
In Quantum Mechanics the Hamiltonian 𝐻 is the generator of time translations.pic.twitter.com/aiWy07aaMo

This is probably related to Noether's theorem.

Més o menys, el teorema de Noether diu que tota simetria porta associada una llei de conservació, en particular la de la magnitud que genera la simetria. Però el tema de simetries i generadors és més fonamental.

What is relativistically meaningfull t for a field ? A particle has a proper time. A field may be descirbed on an indexed sequence of spacelike surfaces but there are infinitely many such sequences.
