What If Dark Energy Doesn’t Exist?
Dark Energy is what we call the mysterious force that seems to be pushing the universe apart. By some calculations, it makes up 70% of everything in nature. Or...maybe it doesn’t exist at all! Plus, Juno’s observations give us new...

Chris Anderson (TED): Questions no one knows the answers to
TED curator Chris Anderson shares his obsession with questions that no one (yet) knows the answers to. A short intro leads into two questions: Why can't we see evidence of alien life? And how many universes are there?

TED-Ed: Dark matter: The matter we can't see - James Gillies
The Greeks had a simple and elegant formula for the universe: just earth, fire, wind, and water. Turns out there's more to it than that -- a lot more. Visible matter (and that goes beyond the four Greek elements) comprises only 4% of the...
