I am 13 (interested in physics i know stuff like temp is just average kinetic energy and also entanglement and dirac equation and also computing but i always thought how we even come with this math or etc stuff that an particle may or may not be there until its measured (when an photon falls on particle) and also an question (only if you are student of particle or quantum physics) we know that higgs boson is an elementary particle but then how did we know it was responsible for higgs field and all other stuff but due to particle decay we cant even see it (even if higgs boson dont decayed we still could not see it) then how did we or anyone can prove that its due to this particle that higgs field is there and how we know that this a particle (that we have never seen) interact this way with other particle

As per quantum or particle physics an particle can never hit zero energy but what will happen at null infinity like if an photon is going towards null infinity it cant just go through it nor it can stop. And dont use BMS as BMS says that when an particle reaches the null infinity something soft and hard participle(explain pls) and as per your explanations make that i way i know gravitational wave memory effect

Like how do we mix gas into liquid without turning it into liquid or solid...And how do we even compress an gas like how its possible at a fundamental level
