Ummm I think I refering to the first YTMND that talked about lasers. Not player h8ing or anything, I love you if anything since people who have a decent understanding in these kinds of sciences are rare.
Okay, you're misleading these people. The detection of the photon means that something must be fired at it, ultimately collapsing the wave function by touching it and throwing it off course. The uncertainly principal says that you cannot know the exact position and velocity of an electron, photon etc. Either you know 100% where it is and 0% velocity and so on. The photon does not "know" it's being observed. Wikipedia "Uncertainty Principal".
