Last night I was able to catch the second episode of the latest NOVA series, The Fabric of the Cosmos. (Have you figured out by now that if you put “cosmos” in the title of something, there’s a 99.9% chance I will like it?)

I am as average a layperson as it gets when it comes to science, so I had to admire how the show’s team explained concepts such as the past, present, and future all existing at once, or why time appears to only flow in one direction, in the simplest way possible.

Check it out–the last two epsiodes are on the next two Wednesdays, and you can get caught up on the first two online. (And I dare you not to think of Dr. Who while the show talks about the nature of time. Sorry, physicists.)
