|Remember Toon Town?|
A newly begun experiment will, just maybe, ascertain that we're all toons. See (from the University of Chicago, one of my alma maters), "Do we live in a 2-D hologram? New Fermilab experiment will test the nature of the universe."

Or perhaps the quirkiness of quantum mechanics -- like cats that can be at once neither dead nor alive -- has to do with a different unprovable: the Many Worlds Interpretation. As in, "Parallel Universes Exist - And Could Explain All Physics, Says Griffith University Study."
Starstruck: half of universe's stars are orphans with no galaxy."
Stars are very distant -- but how exactly distant are they? It's not an easy question to answer; different techniques and measurements have yielded different estimates. What we (think we) know is that stars are so distant that -- given the finite speed of light -- to see a star is to look (at the least) years into the past. When we peer into the far distance, we look into -- and form our understanding of -- the remote past.
The estimated distances to particular types of nearby stars and star clusters are used to extrapolate the distances to similar stars and star clusters observed in remote galaxies. Hence, any uncertainty in nearby stellar-distance measurements affects our characterization of the universe as a whole. That would make it a Big Deal (TM) if, in fact, "Pleiades distance debate resolved, say radio astronomers."

And for one physics-intensive post, that seems like ample string-theorying you along :-)
