Here's something that will trip you out for life...
Take a laser pointer and go into a hall of mirrors. Or point it inside a cube of mirrors, etc.
You'll see the beam zig zag around and create little dots of light on the surface of the mirrors. Where ever the beam bounces you'll OBSERVE a dot of light.
Is each dot of light an actual particle, an actual star or an actual electron?
All of them are illusions except 1.
The source. The laser pointer.…
