As far as the universe is concerned, so much of it is so far removed
from our common experiences, that it's simply impossible to comprehend. 
It wasn't that long ago, that our galaxy was considered to be the entire
universe or that the earth was claimed to be the centre of it.  When you
get into the possibilities of how things work, possible multiple
universes, multiple dimensions, foam and more, not to mention the
weirdness at the quantum level, it's best not to claim absolutes, when
all you can honestly say is "I don't know".  One example of something
that was at one time considered to be impossible is quantum tunnelling. 
However, without it, solid state electronics would be impossible.
