Why Do People Say We've Reached the End of Physics?
Our fundamental picture of the universe seems pretty nearly complete these days, to the point that some people are suggesting that we’ve arrived at some version of “the end of physics.” And sure, physics is at a turning point, but it...

What If the Large Hadron Collider Made a Black Hole?
Making a black hole in a particle accelerator sounds… a bit dangerous, to say the least, but scientists think that it could be possible! Here's why it probably wouldn't be dangerous -- and might even teach us something.

TED-ED: The death of the universe - Ren_e Hlozek
The shape, contents and future of the universe are all intricately related. We know that it's mostly flat; we know that it's made up of baryonic matter (like stars and planets), but mostly dark matter and dark energy; and we know that...
