There's many other quantum phenomena that don't make sense or aren't logical. 
When an 
electron moves from one atomic orbit to another, it doesn't move; it vanishes 
in one orbit 
and appears in the next. Another example: in quantum tunneling, an electron can 
across a barrier, even though the electon lacks the energy to cross the 
barrier. It just 
pops up on the other side. Entanglement allows two photons to share the same 
identity: they 
are both the same photon, even though they are kilometers apart. Whatever 
happens to one 
photon will happen to the other simultaneously. There is no signal and it 
happens instantly, 
without any time lag.

And of course, there's the wave/particle nature of photons: a photo is a wave 
and not a 
particle; a photo is a particle and not a wave, and both conditions can be
