Is the Moon there when nobody looks at it?

[quantumcarl]

I used the moon as an example to illustrate the same question in the Quantum Physics Section of PF.

If no human has observed the moon or been able to calculate its existence through studying its physical effects... does the moon exist under the terms and formulations of quantum mechanics?

this got quite a few replies from some excellent sources on PF not unlike this thread!
