Let's say we track a photon... starting from sun and reaching earth.

When the photon moves through space (maybe because there is vacuum) it looses no/little energy. Now... when it enters atmosphere?

When it goes through glass plate? or through ocean or through water vapour? Does it slow down?

Is there not resistance?

however a quanta is the lowest possible energy amount, thus is can only be all or nothing?

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
