How do they get particles to hit each other? On the border between France and Switzerland is the biggest science experiment ever built. It’s a tunnel, over 100 meters underground and 27 kilometers long. Inside that tunnel, scientists put a long blue tube… and inside that tube, they put two pipes that they keep colder and emptier than outer space… and down those pipes, they fire particles smaller than atoms in opposite directions, pushing them faster and faster until, when they’re almost the speed of light, they finally smash together! But… how did scientists get those tiny particles to actually hit each other? Here's the answer. It is amazing that humanity can do this. If you like optimistic science and tech stories, follow to see more from our show Huge If True.

Why do scientists smash particles together in a massive underground tunnel? And now, why do so many scientists say that what we really need to do is build... a BIGGER one? For our new episode of Huge If True, we traveled to Switzerland to visit @CERN and explain the Large Hadron Collider. How particle smashing works, why we do it, and what might come next...

Our new CERN episode is quickly becoming one of our most-watched episodes of Huge If True yet! It's now neck and neck with F1 Cars (another of my personal favorites) 👀
