Katie just makes me feel so inspired to stay in my science journey. 💫
Oh how wonderful it is we have access to some of the most brilliant scientists in the world at the tip of our fingers. Thanks PI for putting this on.
Katie's so cool! *-* Imagine being able to study all of these rad concepts each day!
As she points out, "unfortunately quantum mechanics comes in and ruins everything".
I feel so much better knowing a little more about some ways the universe may end!
Thank you very much for you the talk.
Your enthusiasm and passion make matters fascinating, even more so. Congratulations!
i love people like you guys. thanks for adding to my understanding
of this relatively macro end of this incomprehensible thing i'm in
Magic Katie, thanks for being, in this or, any other time, your radiation belt is forever illuminating. GRACE.............
I loved watching dr katie who is both young and so enthusiastic about her field. being an elderly watcher who has been interested in cosmology since hoyle murdered any chance of the phrase big bang to be serious may the young geniouses carry on to the end.
Hozier brought me here! :)
“As Mack explained, there will be darkness again”
What a GREAT interview!
Great every student need to listen your so much positive conversation 🙏🙏 Katie g and gentleman
Nothing matters to us but our comfort and status of now ..we're designed that way.
I like your presentation of expaining various concepts. Certainly, at some point, a scientist becomes a philosopher with having gained such a very profound scientific perspective of all of existence. My background is Physics (particle) and Mathematics, and I wrote a short story of science fiction that demonstrates my desire for the undiscovered physics to enlighten and enhance our existence in ways that we cannot fathom. I hope your research and passion will reach these points of discoveries to have closer encounters with new realities. Anastasia
This is quite inspiring conversations I actually listened minutely..I am Greatful both of you ..you tube and video this is most exciting to know from the end of Universe ..rather title has to replaced by The end of Universe now expand so positive optomestic the conversation I felt 🙏🙏 Hello namastey you both ketoeg and one other gentlemen 🙏🙏it's awesome..this is explained very well ..yesyes welldone well-done..galaxies pulling togather ..clapping clapping so positive ..
This is the end beautiful friend .... the end🎶
Good....more lectures and talks plz..i think i shud turn physics from a hobby of mine to a career
I keep wondering, why do cosmologist always refer to galaxy collisions, but then continue to state there will likely not be any collisions. Should it not be galaxy mergers then ?
I think our host is smitten with Dr. Mack
I would like to purchase that book
I want more of these videos. I have no idea why I am into it because I have no science background and am currently living in the armpit of the south working from home making craft supplies. Anyone else listen into quantum physics and chats like these and have no clue what or why but just find it peaceful to hear? I am by definition a poser :) I sure envy these super intelligent women
The universe is endless, as time itself is a human construct. From 2004-2007 I experienced persistent interference from beings that exist in another realm. We’ve all heard them described with various human words: Angels, demons, orbs, spirits, etc. Whatever they were, they were very real, exist around us at all times, like particles, but we just can’t see them. They were awesome (terrifying), and infinite ♾ in number. There were dark beings, which remained on the ground, in the form of gnomes, or trolls. They were scary, but I wasn’t scared because I knew they couldn’t touch me, from a sense of protection I felt from the light beings flowing in the air above everything. They were incredibly beautiful lights that changed in and out of every color known.
In ‘07 when I saw the Great Spirit, The One we’ve given so many names to, I fell prostrate before it. I was paralyzed on the ground, trembling before this blinding light. There is no accurate way for me to describe the emotion that I experienced during this encounter, because it’s unlike any emotion we experience in this world. I was filled with a powerful terror from the realization that this all-powerful being could literally tear the flesh and tissue off my bones and shatter me into pieces, with just one breath. But that intense fear was mixed with, and ultimately overwhelmed by a feeling of peace that surpasses human understanding. What I understood was that it could destroy me, but it would NEVER do that, because it loves me with an endless love.
For apparently no reason, these things happened to me, a nobody druggie in this world, on a collision course with the grave...on a collision course with the unobservable universe...
Ok well I have to head to circle k now to pick up some shampoo and prolly some doughnuts. Love you bye!
Did Katie happen to speak to anyone at the Vatican Observatory? I'd be interested in hearing their take. 🙈🙊🙉
@@qed100 Yes, I'm familiar with their capabilities, which makes me even more curious and interested in knowing their perspectives on the theories and likelihood of an end to infinity, eternity, and the universe(s) (?) ... and, what of the other dimensions, and the dissolution of the Aether? 😉
Just finished her book - it was freaking fantastic.
Does space have mass? Could there be different densities of space??
"Does space have mass?
Mass/energy does, and those warp space and THAT puts energy into space-time. As for density, that again should be effected by the warping of space-time. Its not space AND time, its a set of space-time, at least in General Relativity.
Ideally to travel through space be a particle. Curve 1905 to 1935 is mass energy content generation per space. Going faster then light in water is like....trying to curve in high field. Hey thanks. Back gravity induction component manufacture.
@@EthelredHardrede-nz8yv Entangled. Advanced Relativity is not going to push black hole. Adjust from angle of cirlce projection to angle tone out and curve space to center stick. Fly well my friend.
A question. How do we know we are seeing everything that there is to see in our universe? I have an ant mound in my backyard. If you give them a telescope they'll see all of my 1 acre lot. Maybe they'll see into our neighbor's and maybe the entire city block. the will have no idea of the earth, moon, sun and stars. If they point their telescope upward they might see stars and endless void. How do we know we are not handicapped like them.
Vacuum decay, heat death, big crunch... what are the other 2 main possibilities she talks about in the book but doesn't bring up here?
Vacuum Crunch, Big Decay

I'd say that even in the most extreme examples our mathematical models can at best only be incredibly accurate simulations. They can not acquire reality.
"They can not acquire reality."
They may fit reality exactly. Doubt it but the math might. Many things in physics fit the evidence far better than the original limits of observation. The math has often fit things that were not even thought of till they were found later and then found to fit the math.
Ethelred Hardrede
He shut down (very quickly) her attempt to get into "virtual universe theory"
Didn’t sound to me like she wanted to. Rather, it sounded like she took offense to the issue.
It's not sad it's just the way it is..... maybe
I would love to see her and Neil deGrasse Tyson speak!!!
Is there any chance a black hole would appear in near earth?
Simulated, yes.
Simulated event horizon will never power project such.... I thought I was insane. Your concept is extremely difficult and sounds deadly.
You can skip the first 2 minutes.
How about the possibility that muliple black holes could merge in a massive super black hole growing larger over the millinium ultimately creating such a large gravitational force that it could consume entire galaxies. Is there a theoretical limit to the size black holes could achieve ?
Just a thought .
Black holes do merge, and that is partly how the super-massive black holes at the centre of galaxies are thought to form. However galaxies are billions of times bigger again than even the super-massive black holes at their centres.
19:42...I just had a thought...this change in the value of the Higgs field, or some similar jump to another level that changes the very nature of reality, may be the way that the universe finally ends, or rather enables a new big bang to occur....after the heat death of the universe, when there is almost nothing at all left, all particles are gone, no more black holes, all that's left is say one super long red shifted photon and then it is finally red shifted, expanded so far that for all intents the entire universe is then a completely uniform dark, cold, empty void, there would seem to be no difference between this state and a state of absolute nothingness, under these circumstances, any slight perturbation, of any kind, maybe that last deeply red shifted photon just before it evaporates into nothingness, is the catalyst for a complete inversion of the physics that govern the quantum nature of the vacuum on the cosmic scale, after all, the slightest change, a minute quantum shift in a universe of absolute nothingness is perfectly analogous to a big bang. That small volume-less point of instability or change , would have none of the usual forces of nature acting on it, no gravity because there is no matter, no weak and strong nuclear forces because there again there is no matter, no outside forces at all to stop it from expanding faster than the speed of light, such as the Higgs field, so this point of instability has nothing to impede it's expansion until it reaches a certain volume that dilutes it's energy, temperature, enough to allow the forces of nature to condense out as distinct effects. Studying matter is obviously a darn site easier than trying to study the true nature of perfectly empty space on the scale of an empty universe, hopefully our research and our math and technology can fill in the blanks.
I agree 😐maybe vacuum decay all ready happend😐 in the past or maybe something else after all the past is all ready set 😐so something had to create the Big Bang 😐we don know what in fact the Big Bang only explains the explains the formation of space but not the mechanism behind it 😐and if vacuum ether way the universe will end however some how this universe was even created in the first place 😐and we say time and space was not a thing but maybe something did happen 😐that caused it after all gravity is a force just like life and death are forces we can’t see them or measure them but their their 😐 also the universe will end who knows when 😐but ether way you look at it some how we live in only 14 billion years 😐for now and until we have a understanding of dark matter and energy we may have a better picture 😐but saying that the universe will end forever is like saying the earth is better off dead 😑and yet somehow it formed 😐as time goes on I bet the more time humans understand the cosmos and the universe as a whole we may have a better picture 😐
how can we even have a model or a theory of the end of the universe if we don't know what 95 percent of the universe is?
we actually have no idea how big it is , it breaks my heart when so called scientists say our algorithms predict the universe is this big, when the information is not 100% and more like .00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001 , Their prediction is nothing more than a religious claim .
I think Isaac Arthur covered this topic in a much more thorough manner, and he had better visuals, lol
Deodexidus Isaac Arthur is a UA-cam personality. Katie Mack is an astrophysicist. I much prefer listening to Katie.
She’s awesome
We are all doomed. Enjoy the moment.
If you consider the onset of a multiverse! The universe as we know it has Already gone bye bye
Everything in Canada is a non-profit. When you say Canada it means no profit. Maybe they should study that?
Big Crunch is less scary than Big Rip because it gives you almost infinite energy to use to figure out "a way out". Though with ambient energy increasing it might be difficult to create energy potential differences.
The goal of all humanity must be to escape this and become gods.
I know we have evidence for the largest scale structures that we know of, galaxies, and galactic clusters, moving apart, but what about at the limit of our concept of the deepest structure of the cosmos, the webs and voids of super clusters and so on, is this all expanding evenly or just condensing into bigger emptier voids and denser filaments because of gravity ? Also, how do we know that the big bang's inflationary effects have ceased ? how do we know that there is not some left over kinetic effect, or energetic effect on space itself that can account for the continued acceleration ? To me, without having any real proof obviously, 13.8 Billion years is still an extremely short time since the big bang in terms of the universes future potential age regarding the dynamics of space and matter...I wouldn't be at all surprised if the big bang is still having it's way with the universe in terms of expansion, thoughts ?
LETS' HAVE A DEBATE !!! the ELECTRIC Universe model of the Cosmos and NASA's model of the cosmos ! The EU has an open invitation at any time! Now that would be exciting !!!
Let’s not have a debate. Your Electric Universe is nonsense.
No, it wouldn't be exciting, I'd be a waste of NASA's valuable time. They have a lot more important things to do than arguing with cranks.
THe heat death may very well be true and take several trillions of years . And imaging you were on one of the last stars and planets and could look out and see nothing besides your own environment . You would know you were something special . How could an event ( our universe ) express in an infinite progression of unending magnitude , and not be a repeating cycle . And if not we would be unaware of anything on into infinity and would not give a rats behind anyhow.
I wish i had , Seems like i know more about the universe today Arcadic Liabry
it is OK to make fun of flat Earth people,,,,
I don't see space and time as "real" or "things" because they aren't conserved. They aren't like charge or momentum or something. We know from Relativity that they vary with reference frame.
time has no beginning no end time needs nothing to exist , even if ther were no mass there would still be time,we live in a multi verse with no understanding of it
If the most galaxies are receding the fastest, and being the most distant means we are observing them from their distant past, then we are seeing that distant galaxies used to recede faster than closer ones do now. Imagine being at a point where a bomb exploded, but after that event. You would see the outermost fragments receding fastest, faster than closer ones.
24:13 I disagree that this could happen, and assuming that the Higgs is at present resting at an energy above it's lowest possible value, then if it can happen, it would have already happened. The reason it has not happened already is that it would require a wholesale rewriting of the laws that govern our very dimensions of space time, and, more specifically, quantum tunneling.
The concept of quantum tunneling is generally thought of as a way of particles to sneak past a barrier, this can happen at the smallest of scales because there are additional extra dimensions at this scale of space time, that seem hidden to us at our scale. Just like if you look at a perfectly flat surface with your eyes, you see a two dimensional flat surface, take a look with an electron microscope, and you see a complex three dimensional image. It's these hidden dimensions that allow a particle to appear to sneak past a barrier, naturally these effects are only noticeable at very small scales.
She's way too happy about the end of the universe.
REM: It's the end of the world as we know it, and I feel fine.
How many of these ideas are instantiated while having a drink at Perimeter's Black Hole?
A Canadian with a sun burn ...... thats something you don't see every day 🤣
lol!
Where will you be for eternity??? Heaven or Hell.... you can know.... read the Bible.....
interesting space ? all things eventually change into something else ,water for example will meet air somewhere and the pulp of a tree will turn into bark then meet the air ,space must be the same way ,eventuall if you go far enough space will lose its uniformity and change into something else ,all things do this so space must as well ,
The harsh truth is better than a religious delusion, science over mythology.
7 more force in the Magnetic field ... vector fields are not detectable ... Now I don't know any science math that would tell us when were going to fly like a bird or be crush to the 🌎..
Bro people are really taking as if they know what's real and what's not, the universe is expanding only in our heads, and did begin also there
7 yrs .. I Know this .. our planet will be a sand dune ... Here come the sun 🌞
Too many "ah, ennn, err....'"
THE TRUE AND CLEARLY PROVEN MATHEMATICAL UNIFICATION OF PHYSICS/PHYSICAL EXPERIENCE:
Consider the man who is standing on what is the Earth/ground. Touch AND feeling BLEND, AS ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=mc2 IS F=ma. This NECESSARILY represents, INVOLVES, AND describes what is possible/potential AND actual IN BALANCE. Time DILATION proves that electromagnetism/ENERGY IS GRAVITY, AS E=mc2 is DIRECTLY and fundamentally derived from F=ma. SO, the mathematical unification of Einstein's equations AND Maxwell's equations (given the addition of A FOURTH SPATIAL DIMENSION) proves that E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Great !!!! Gravity IS ELECTROMAGNETISM/ENERGY.

Hi, i'm quitting youtube since they''ve stooped to autoplaying racist propaganda on their front page. I'm going over to Storyfire.com and would like you to consider uploading there so i can continue to enjoy your great content. If not, well, thanks for the videos, but i won't watch anything on UA-cam anymore. Please consider uploading on a platform that doesn't force racist hate speech down my throat so i can continue to support you as a creator.

Go ahead, produce a paper, from a science journal with that 132 crap in it. QM has four dimensions in the Standard Model. String theory has more and m-theory has one more than String only neither are actual theories they are hypothesis. 132 is your own personal crap. Its crankery.
