Once you've nailed the universe, its contents and its size. Try tackling this one.
What IS gravity?
That'll really mess you up.

Saw that last night and it was indeex excellent. Whilst I sort of knew much of the story it was still a delight and included snippets I'd not previously known or had forgotton. I think the Penzias and Wilson discovery of the cosmic background radiation to be amongst the most amazing result in all science. I can just imagine how they felt when they realised what they had actually stumbled across.
Jim AK is my favourite science broadcaster, though Cox is also good in fairness.

I love the stars, I go out on motorbike (with telescope) into the Dales just to see them away from light pollution. I can sit and look for hours. 
But I am such a dunce I can't grasp astronomy, I keep going back to my "Astronomy for dummies" book that I bought a decade or more ago, but I still can't get past stuff like sidereal days without my head hurting, that in turn, brings back memories of my dad getting mad with me whilst trying to explain the dark side of the moon with an apple and an orange. 
I am currently reading "An astronomer's tales - Life under the stars"

A book? Why read a book when you can watch the movie?...

Well here`s one to get you thinking.In this image of part of the Andromeda Galaxy there are in the region of 100,000,000 stars
The stars that look like stars are in our galaxy
The stars in the Andromeda Galaxy look like diffuse light but as you zoom in they become clearly identifiable as individual stars.

It's the scale of it that I find hard to visualise: 100,000,000 stars in just one part of one galaxy!!! Quite staggering really.

I think a trip to a sandy beach might put it into some perspective a bit better.
I think I can remember Carl Sagan saying about grains of sand and the number of stars in the universe.
