The 1977 film Powers of Ten is short and simple but gives one a better feeling for what infinity represents (40 orders of magnitude isn't much in contrast to infinity, but is very large):

There's also an hour-long talk by Prof. Raymond Flood on Cantor's Infinities on YT that covers all the mathematical history.
