  1. On the expansion of space - we don't even know if space is expanding. It is a hypothesis based on redshift (as explained by Joe). But it has never been experimentally verified. And we have no known physics explaining how this expansion should work (hence 'Dark Energy') - which again has not been measured. So the concept of an expanding universe can easily go away as fast as it was invented.
