Craig nothing is real! We have labels for things we can perceive directly with our limited senses and our brain gives us an interpretation. Then we go and put labels on things we can only perceive indirectly with ever more exotic instruments.
Reality is stranger than we can imagine. The classic double slit experiment showing inteference of light looks quite logical until you only have one photon at a time in the system and the interference pattern is still there.
This has been done with Buckyballs. So a C60 molecule has interfered with itself by going through two slits!
The only conclusion I can draw is nothing is real until it interacts to produce a macro phenomena.
Taken to its logical extreme our conciousness only exists because of lots of fields and particles interact constantly. Stop looking or being looked at and you cease to exist.
Even quantum entanglement is stranger than usual. Here

I am going out to play in my observatory before it dissapears. May just check my tinnies in the fridge as well since they seem to dissapear for no known reason.
