In your opinion, what is the most important discovery in the last 10 years?

That the universe is not slowing down in its expansion, it's accelerating.

And, do you know why?

Hey Mr. Science guy! I grew up watching your show and it definitely influenced my path towards engineering. My question is what science fact absolutely blows your mind?

u/sundialbill replied
