You can still have realism, but it must be the case that at least some of
the things we think of as ``real physical objects´´ like e.g. electrons are
not real.

Suppose you are a virtual person, programmed by me and living in a virtual
environment. You do some experiments to find the laws of physics. You try to
break up things and look what they are ``made of´´. Would you ever discover
how the pentium processor works if you proceed this way?

Similarly would you ever discover anything about neurotransmitters and
neurons while you are asleep (and dreaming about doing experiments).

It is more likely that you would be stuck with theories that promote
nonexisting artefacts of the virtual world to real physical entities.
