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

9601 ratings | 721912 views
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.)

We could live in a simulation. There could be trillions of other Universes. What if our universe was only a drop of water on another planet in a completely different universe. In that universe we could be smaller than atoms are in our Universe. We could literally be in a petri dish in a lab somewhere. We could fall off a table and our universe could be destroyed and swept up later and thrown in the trash. Every single atom in existence could contain trillions of Universes.

Surprised he didn't mention the other 20+ constants that also needed to be precise for our universe to exist.

Far-fetched speculations from another nerd who tries to explain data and mathematics too complex to simplify. Pretty​ lame and trivial...but he looks to be pretty satisifed with his speech...An applause then!

Alessandro Rossi (2 months ago)
He said this phase change would expand at the speed of light. If he has a reason to say so, it means it would only destroy a part of the universe, since its expansion separates itself into parts without causal connection due to a division speed faster then light (relatively speaking). So I think the universe will survive this and die for entropy instead, until every casually separated part will collapse at the same time, since in infinite time everything which can happen does happen.

Of course if you accept the existence of a multiverse you must also accept that something connects the constituent members of that multiverse together, in which case they could be compared to Virtual Machines all running on a single OS, and if you assume that OS to have less than infinite capacities, and more multiverses of possibility are created moving forward in time, you must also conclude that each would receive less of those capacities over time, invalidating the view that everything should continue "at the current rate" over time, but rather enforcing a curve on resource allocation to any one instance in a given universe, causing deceleration in some form.

When we stop fighting as one village with the next and country vs. country, and we are all working together rather than chasing profits like Ferengi, we will then make leaps and bounds never able to be imagined with science. We have more to gain working together than being hard headed and drawing lines and living by old religious rules. Recycling should be mandatory, pollution should only go down. Ford engineers putting 15 things in front of an oil filter should be outlawed. Cruise ships dumping garbage and unprocessed sewage should be illegal world wide. That is why ISIS is mad...

🤔...That’s what I think that we live in Era, on temporal point of view, and, at same time, on a Phase of Transition of a Universe in expansion on high acceleration on another mathematical point of view.. ☝️🤨... Someone have some idea to help?

If our universe is just a grain of sand among many grains of sand, then his sand dune hypothesis falls apart, because individual grains do not fall apart nor morph into other structures. While sand dunes are almost as transient as waves on the sea, grains of sand, which make both the beach and sand dunes possible, are very stable.

here we are sitting down arguing about global warming and who can fornicate with who and what the rules are about how they do it and whether or not a fetus is alive or or whether people can choose to not sell Kate's to people because of who they bang or what bathrooms people can uses to people because of who they bang or what bathrooms people can use or whether or not global warming is real meanwhile the very stability of the universe could at any point in time and without notice end got you imagine all those virgins were about to get laid and then suddenly woosh
ordinarylover (3 months ago)
I don´t care too much how the universe was made, although I understand it is an important question... What I really would like to know is why ? Why there is something called Higgs field ? Why particles gained energy when in contact with this field ? Why all these things exist to begin with ? I mean if you think about it nothing makes sense...I know you don´t need a sense for things to exist that is pretty clear but still I don´t think that knowing the "how" is that intersting...I know this knowledge is usefull but it is just not that appealing to me

So alright, i hate these speeches, every time you have a question there will be no one there to answer. But, against the odds, i'll ask this nonetheless. So, the sun will turn into a red giant, and then "kaput", i get that, so is our lil planet destined to fall inside of it, if it won't burn into a crisp before that, i'm wondering, what about the gravitational pull? If the sun gets bigger, and i must guess, massier, won't the planets slowly drift away from it? Cuz we all know it, the sun pulls on the earth as much it does on the sun, so won't the orbits of planets adjust to the ever so slowly change in mass of the sun? I can't explain myself better than this, as i lack a lot of technical terms, but i don't believe the sun will just swallow it's own planets out of the blue, or red in this case.... for a better use of words, are planets just gonna plunge into the red giant? Instead of adjusting accordingly, even if that meant getting too close, or too far away, and unavoidably kill all its life. I NEED A PERSONAL ASTROPHYSICIST ASAP

The idea that our known universe could be just one of many is actually to my surprise mentioned in the holy quran or the book of Muslims, it says that there are seven universes and ours is the lowest of them all and it says that there is 500 years between earth and the edge of our universe and 500 years between each universe and after the seven universes comes something called the chair which is holding all the universes from falling on each other , and after that comes the great water which is also 500 years deep and above the water is the throne of god, the thing is.. the book never specifies 500 years of what. is it 500 years of walking? or is it 500 light years? or is it even 500 years of something faster than light speed! we don't know... i'm not telling you this is true by any means, but if you think of it, it is actually true to some extent.
sasuriii (2 months ago)
yes, but try not to mix Quran with words from Hadith and give references whenever you mention scripture. "The Most Merciful above the Throne established" [Taha 20:5] Abdullah bin 'Amr bin Al-'As narrated that the Messenger of Allah said:"If a pellet like this one, and he pointed to one like Al-jumjumah were to be dropped from the heavens to the earth – and it is the distance of traveling five hundred years it would reach the earth before the night-fall. But if it were dropped from the top of the chain it would travel for forty years, day and night, before it would reach its foundation or bottom.” It was narrated that Ibn Mas’ood (رضي الله عنه) said: "Between the first heaven and the one above it is (a distance of) five hundred years. Between each of the heavens is (a distance of) five hundred years. Between the seventh heaven and the Kursiy is (a distance of) five hundred years. Between the Kursiy and the water is (a distance of) five hundred years, and the Throne is above the water. Allaah is above the Throne, and nothing whatsoever of your deeds is hidden from Him." (narrated by Ibn Khuzaymah in al-Tawheed, p. 105; by al-Bayhaqi in al-Asmaa’ wa’l-Sifaat, p. 401). While speaking about the ‘Kursi’, Allah says, ‘His Kursi extends to the heavens and earth.’ (2:225). It means that His Kursi is so great that it extends to the seven heavens and earth. While speaking about the Kursi, Abdullah Ibn Abbas (R.A) said, ‘The Kursi is the place where the Qadamain (feet) of Allah rests and the Arsh, no one knows its extent except Allah.’ (Tafseer Ibn Katheer, Vol.1, Pg. 548 Dar Al Kitab Al Arabi Beirut 2013). and i never did i heard chair (kursi) is holding universe from falling. thats not what we learned as muslims.

Ummm... The Higgs field can exist in two states dense and not. But the dense variety would expand at the speed of light? Wouldnt it need to be of some intermediate density at that time?
aeia dansari (4 months ago)
Doktor Acula (4 months ago)
If in those thousand billion years higgs field would even collapse then it wouldn't change anything, because collapse travels at the speed of light while universe expands faster than that.
nipi tiri (4 months ago)
The expansion of the universe is more of a "stretching" than traveling at a speed. A distance twice as long stretches twice as much in a given unit of time. So it would matter how close to us the flipping of the field occurs.

Castor (4 months ago)
This video coupled with the recent potential evidence of long-dead black holes from a previous universe seems to give an even stronger reason to believe in a cyclic universe - multiverse or not. Perhaps dark energy is constantly there to push expansion, but this transition to a different state of Higgs field might be a part of the way to starting from scratch with a new big bang, as a way of overpowering a seemingly unstoppable force. I don't say that to imply a meaning, of course.

What if these Higgs Boson mass particles are a kind of physical particles that relate to the 4th dimension world?
