From a different angle of an answer to your question you may want to ask what is the biggest BEC "super atom" ever created.

comment Can a buckyball gun be fired by observing it?
I'll read up on de Broglie boxes. Be careful about using the words "any type of matter" it inspires questions about dark matter;-)

comment How far out from the Sun is visible light still sufficient to read a book?
Yep you are. I was refering to the point where reading becomes impossible.

Ok but is that from the photon's energy or from the uncertainty in position or momentum?
