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

8923 ratings | 684101 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.)

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...

it's not the "God Particle" but the "Brahman Particle" - Brahman is everything - you, me, the earth, the sun, the empty space, the galaxies, the entire universe is ALL Brahman. God came out of the Brahman - he is a step lower

🤔...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

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.

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?

Doktor Acula (1 month 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 (1 month 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 (1 month 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? Recall that a sphere (3d) would do crazy magic for the 2 dimensional world, a point appears out of no where, then a circle appears, now the circle is getting bigger, now its getting smaller, now its a point and its disappeared.

Great hypothesis
Wow what great information. Thumbs up. Love it... but... speculating on things that can never be tested scientifically (id est, a multiverse) is not science. Its fine to speculate on such things, but lets not call it science. Whether it was a chance due to large numbers of big bangs or cosmic meddling to set the universe on the knife edge, "the theology department is down the hall."

Trading Post (3 months ago)
Well now science is proving that the Universe couldn't exist as it is from a nothingness unless there was design behind it, the odds of something coming from nothing & becoming our fabulous Universe that seems to be built so life will exist here, how can a live single cell be in existence without a creater, where could the spark of life come from? Exactly the same as the Universes creation, its down to "design!"

You humans and your assumptions, your mathematical model is incorrect. The higgs field has no capability of quantum tunneling, its energy levels exceed that of the subspace capabilities. If such an an event occured, subspaces energy levels would exceed that of your three dimensional space, which is not possible because to be (for the lack of a better word) "subspace" its quantum energy levels must always be lower than active space, the space you know. This would inevitably lead to the collapse of subspace, but thankfully the redundancies in this Universe are prevalent, this collapse would lock Active space for 5.39 × 10 −44 of a second (Planck time, one thing you did get right, but not for the reasons you believe, you got lucky) before it reset itself. Since this freeze of active space is so short, it isn't noticeable. But, that is simply our assumption since subspace has only been observed to reset when electrons get too close to similar energy levels. By the way, we estimate you'll discover "Subspace" in the next 30 years or so, that'll open up ways to manipulate gravity and transport large objects. The transporting will take time though, your computer systems still need a long ways to evolve before they have the processing power to calculate how all quarks are assembled in the objects your teleporting. It brings back memories from our history watching these videos, how little we knew yet how much we thought we did. I wish i'd be around to observe your discovery of subspace, its a game changer. Good luck.

"Why our universe might exist on a knife-edge | Gian Giudice" no no no. There is nothing to fear, because there is God. And you knopw that nothing is happening to the universe. what did you see?- exploding gravity-fed-black holes???? Believe me, man, that was your delusion because black holes don't exist, because gravity does not exist, because time as real does not exist, because space time bending/warping exploding is impossible and pure fiction.

A religion said that this universe is the smallest of 7, it is compared to the Sahara a ring in the desert from the this universe to the next universe and that a barrier is between each one. How it is described it is like the Universe we are in was formed inside the next and the next is formed in one before that. It says God is from the 9th and it was the first and that the 8th we can not enter and the 7th we can exist.

About Highs Bostom and Subatomic Particles... All that Scientist do is...Describe the Formation of the Universe after the Big Bang. I know how the Universe Works. It's like this... SuperGalacticStar (Located on North Pole of a Large Circular Object... Bubble) Collapses into a VeryLargeBlack Hole. Matter falls to it bottom. Breaking it into Subatomic Particles of Matter and Anti-Matter. After a Time these Collide and exit Black Hole. Then the Big Bang occurs. This Matter moves from North to South on the Space that is Black on this Circular Object. How this Bubble was Formed and we're this Matter came from... I know that to. Then the Universe was formed after it cooled down. So from Up... Big Bang...to down... Matter in Subatomic Particals... It go up up... Matter we see today...and Our Universe was Formed. Our Universe will expand up to 180 Billion L. Years (Universe Years). The electron has each a life spans of 10 to the 180 years and Proton up to 10 to the 360 Years. As for... 6 Quarks... 6 Leptons... 1. Highs Bosom...5...W +...W -...Vo... Zo... g... There are the same as to as Anti-Matter. And a Dark Subatomic Particles.. ...Dark. Energy Subatomic Particles...more. I live in Sydney... Australia...neer Black town. I need a Scientist to contact me. Also will put it all on paper. If you read my theory... You will know all about the Universe's Formation... Before... Before... .

Subject: Holographic Universe John, Thanks for sharing this very interesting information with me. It certainly makes sense to me. The Anthropic principle alone should be enough for skeptical scientists to understand that the laws of physics and mathematics are the laws of God's own Mind. Kevin Williams James Gates, Ph.D., a theoretical physicist at the Univ. of Maryland said: “If the simulation hypothesis is valid, then we open the door to eternal life and resurrection and things that formally have been discussed in the realm of religion.” Our Creator created linear space-time which is essentially controlled electrical energy that has existed eternally. Checkout on YouTube: A fractal universe. Time and space must exist before matter can be created, and only an animate entity can conceive of space-time; this prerequisite must be a stabilized and uniform condition before matter can form, thus, monotheism is a Truth. A stable space-time and the Universal Laws of Physics did not happen by chance. On Jan. 17, 2000 at 2 pm, while crossing a river bridge in Burswood (Australia) on my bicycle, I observed a velvet textured beige pearl covering the sun. Within the entity, there were containers in the shape of elongated, seven-pointed Koch snowflake fractal crystals immersed in a white misty light traveling in a ten o'clock direction. I later deduced that the light flashes on the inner space of the crystals were of a binary language conversion pertaining to the senses of all mortals, that is, a holographic universe.
