Why our universe might exist on a knife-edge | Gian Giudice

Показать описание
The biggest surprise of discovering the Higgs boson? That there were no surprises. Gian Giudice talks us through a problem in theoretical physics: what if the Higgs field exists in an ultra-dense state that could mean the collapse of all atomic matter? With wit and charm, Giudice outlines a grim fate -- and why we shouldn't start worrying just yet. (Filmed at TEDxCERN.)

What a cool guy. Usually this quantum physics stuff goes way over my head, but he actually made it fairly understandable. The idea that our known universe could be just one of many was the most mind blowing notion of his entire talk for me.

I am not particularly scientifically minded however his enthusiasm tells me that this is a wonderful discovery and that humanity is in for an amazing

So what will come first? The collapse of the Higgs field or Italy forming a stable government?

I don’t know why no one is talking of the passion of this guy.. maybe because I am Italian and I speak English and I know the way is speaking it is full of love and excitement

That's cool. I don't want to brag, but I just leveled my washing machine. It doesn't rattle anymore

Brilliant talk!! This man is very inspiring in the way he communicates science. It is so hard but so important to make people love physics, we need more men like him: great scientist and researcher but also passionate communicator.

I don't understand why everybody always acts so surprised and awestruck when talking about how perfect our reality is for our survival.
Of course reality is perfect, if it wasn't, we wouldn't be here to observe it.

Thank ☮ for TED Talks, I feel like I have ADHD when I read articles about this kind of stuff, but listening to an articulate scientist explain it makes these ideas so much easier to understand.

We don't know the end of the story, and we don't exactly know how the story began, we don't know why there even is a story at all... but we know there is a story, because we're experiencing it right now.

The sand dune example wonderfully complements the anthropic principle in explaining why values seem tuned.

what this Speaker/Professor is saying proves it, it's a sound concept already, that we should examine it. Thanks to the confirmation of the Higgs field existing, it's cool that we can now think of the multiverse theory as yet another interesting perspective, more or less concisely. Given what a unified framework would be able to represent about what we know about the bits and pieces of reality, we really need this line of inquiry.

I like that he is very humble and open about how hypothetical and tentative this possible new framework is. IMO that is by far one of the most valuable qualities to have as a physicist. Only rarely are hard lined "this is the way it is" types vindicated by future data. But it happens, so we need a few of them hanging around I suppose...lol

He is a great lecturer! I love watching his talks.

I feel like watching this put my life into perspective for some weird reason. Science is fascinating.

This is absolutely fascinating. To think that we are in a universe that is practically perfectly balanced is amazing. It would be very interesting to study the physical properties of other universes. I assume that will not be possible, but there would be whole new fields of physics based on separate universes. Absolutely intriguing.

You just *know* this guy has elite taste in opera, coffee, and supercars

"10 to the hundred years - its even longer than the time Italy takes to form a stable government."

I wonder what kind of results would be found if measuring the Higgs field around a black hole were possible

Awesome talk. There are so many conditions in place to allow for life as we know it to even exist. It just boggles my mind as to what the main reason for all of this was. What created it, and why.
