In quantum mechanics, there are experiments that have yet to find definitive explanations.
Quantum physics essentially explains the invisible processes around us.
It deals with the structure of the smallest particles, such as our matter or light.
Since Young's 1801 experiment on the interference pattern, physicists have explored light in ever deeper layers of the quantum world.
But it all began with Young's double-slit experiment, in which he discovered that light propagates in wave form, visibly in an interference pattern.
To do this, he shone light through two slits.
These two slits did not create two separate slits on the opposite wall where the light reappeared. He saw the light in five different slits, with the center being the brightest and darkening towards the outside due to reflection.
This led to the realization that light propagates in waves.
That was in 1801; today, we have measuring devices that can read photons.
Photons are particles of light.
But what these particles do under a measuring device still baffles every quantum physicist.
No one can explain how this happens. Neil deGrasse Tyson explains it quite clearly.
