is it possible to make something 0 kelvin? and if you did this would it make that particle or group of particles have no motion or kinetic energy? do particles naturally want to move or is that influenced by thermodynamics (heat)? if photons cause light and they are described as an elementary particle than how can they travel through matter, isnt that like a particle going through another particle? is sound just a movement of particles in a wave pattern and is therefore caused by kinetic energy? when we smell are we actually just inhaling particles or do particles release specific energy that causes odour? is it possible using massive heat to separate an atom into just elementary particles? is it possible to manipulate elementary particles sort of like how we can with atoms to build other structures or is that considered futuristic? I know its a lot of questions im just interested in physics and have some weird questions about it but thanks in advance to any helpful replies.
