Kind: captions Language: en It all started in 1964 when a young English physicist named Peter Higgs suggested something about space that was so radical it nearly ruined him. I was told that I was talking nonsense, that I couldn't be right. So they clearly hadn't understood what I what I was saying. Higs and a few others were wrestling with a puzzle which comes down to this. The fundamental particles in the universe all contain different amounts of mass which we usually think of as weight. Without mass, these particles would never combine to form the familiar atoms that make up all the stuff we see in the world around us. But what creates mass? And why do different particles have different masses? Try as they might, no one had been able to answer this perplexing question. Then one weekend after a walk outside Edinburgh, Higs had a peculiar idea. Using mathematics, he imagines space in a new way, as something like an ocean. Particles are immersed in this ocean and gain mass as they move through it. To see how this works, think of a particle's mass like an actor's fame. And the Higs Ocean is like the paparazzi. Some particles, like unknown actors, pass through with ease. The paparazzi simply aren't interested in them. But other particles, like superstars, have to push and press. And the more those particles struggle to get through, the more they interact with the ocean and the more mass they gain. Higs was convinced he'd made a great discovery, but when he submitted his idea to a journal at CERN, it was rejected. Undaunted, Hakes honed his theory further until he was offered the chance to present it at Einstein's old haunt, the Institute for Advanced Study in Princeton. There, he expected his new idea would meet some of its toughest critics. [Music] I was happily driving up the freeway and then there was a sign to turn off for Princeton and that really confronted me with what I was going into. I broke out in a cold sweat and and started trembling and I had to pull off the road to recover. But Higs persevered. It was the first in a series of talks that would convince colleagues far and wide that he was on to something profound. Eventually I I sort of wore them down. I felt I'd sort of triumphed. So I enjoyed the parties which followed. Today the idea Higs pioneered called the Higsfield is crucial to our understanding of space. The Higsfield is everywhere. It's something that even in the emptiest vacuum of space has an effect. It gives you mass. So I think Higgs actually deserves credit for being one of the people that said space is stuff. It has properties in it that are intrinsic that you can't get rid of. You can't turn them off. The only problem there's no physical proof that the Higs field exists. At least not yet. But here at CERN, scientists are attempting to smash particles together with so much energy that they will knock loose a piece of the Higs field, producing a tiny particle of its own. It's as if they're trying to chip off a piece of space. We think that if we knock into space hard enough with particle accelerator collisions that we can actually make a Higs particle come out of empty space. Our whole understanding of matter as we now have it would just fall apart if the Higs field didn't exist. I don't think anybody seriously doubts that we will see it. Certainly if we don't that would be an extremely bizarre outcome. Finding the Higs particle would be a major milestone. Establishing that the emptiest of empty space has an impact on all of matter.
