One of my favorite things about Dr. Keating is his ability to explain things. He doesn't dumb it down, but crafts excellent analogies after giving you a basic primary in the physical reality you might not know. He doesn't get caught up in storytelling, but lays out the facts in an engaging way - no embellishments required.
Gotta love good science communication
The universe is expanding into an infinitely dense layer of cream cheese.
Shut up loser
This true?
Stop.
I always thought that. Maybe its expanding into jello?
Oh, thats awesome, you just saved me 12 mins of watching this video
This is one of the biggest questions i’ve had since i was 10 years old. But no matter what anybody says they don’t know.Nobody knows . There is not one person on the Earth that can explain any of this.
They know but they wouldn't tell the general public because of panic
@@cryptolord9826 🙄
But the guest calls it naïve to question his narrative.
Are you gagging on Christ right now?
I mean what is outside of a box you are stuck inside no matter your efforts? We are talking about what amounts to conjecture and guesses based on what we have inside the box, but the whole point is that inside and outside are separate so there must be some difference between them we can’t know. It is interesting to think about but until we can escape the box it really can’t be known what is beyond its walls.
Edit: I want to make sure to point out that just because information or matter is outside the box doesn’t mean it is completely different from inside the box, it just means we can’t know anything about it. There’s no reason to believe everything “outside” of the universe from our perspective isnt just, more space.
"Typically neurotic" old Polack sees cyclic conformal cosmologic expansion causing rupturable vacuum "weakness" towards the universal mid-region where earlier aeonic big bangs took place; no anti-deSitter space involved; just stress fractures providing a reverse plasma influx portal. Happy New Aeon!
The universe doesn’t expand into nothing, it expands within itself. Meaning the space between galaxies is expanding and therefore expands space time. Time is therefore increased within the parameters of space.
Man I wish I could understand physics like an expert does. Without the life time of dedicated study of it lol
You can
I can teach it to you in a week.
The mathematics is important for being able to _use_ the models to make predictions but not much else.
You can conceptually grasp physics easily enough.
The objective of Physics is to comprehend the universe and everything inside it in mechanistic and mathematical means.
Consider yourself the first person to conduct the study. Observe the universe and the things inside it and what do you notice?
1.) - Matter. Material objects.
The current best model of _what matter really is_ in the most fundamental and most small unit is the Atomic Theory. Including nuclear and particle physics of course. These are all the current model of STUFF and THINGS.
1.5.) Motion. Matter can move.
The current best mechanics are both Quantum Mechanics and Classical Mechanics. They both work very well but only in their respective fields.
2.) Light, heat and other Electromagnetic Phenomena.
Ive fudged it a bit here, because considering light and heat as em phenomena is in fact a theory in itself. But whatever.
The current best model of this is the Photon model.
3.) You want to catalogue the universe itself into a map. This is Astronomy.
Use 1.) and 2.) to catalogue the properties of everything in existence. The sun, distant galaxies, etc.
however there is a special problem here.
Gravitation. How does Matter attract other matter, and what is the best mathematical model for it?
Currently that is General Relativity. Although there is some evidence that it could be wrong.
Whenever we apply it to model the rotation of a galaxy, it contradicts what we see.
4.) Cosmology. This is using 3.) to try and deduct the origin of the Universe.
Imagine studying something for a lifetime and being incorrect at the end of it all.
@Ben Samms What's incorrect and how do you know it is?
Another interesting guess that others have pondered is "What if there are higher dimensions, i.e. more than the known 4-dimensions of space-time, that we cannot perceive, that the universe is just a part of?" Without a way of measuring such higher dimensions we are limited in what we can know.
They cannot be measured because they cannot even be defined. They're indistinguishable from imaginary.
This is like the infinite hotel : You have a hotel with infinite rooms, and every time a new person (Expansion) shows up, everybody moves up 1 room. After an infinite number of movements, an empty space will appear.
I think the universe is infinite, and expanding within its own parameters, via supertask. The answer has to be like this, or else we would've figured something else out rationally by now, right?
Brian, I still don’t understand how we can see light from 13 billion years ago??? Is it ahead of us? Or behind? It’s all so complicated. Is there a book that explains this for an average person? And we missed you last December at the Simxa event ;). ❤
Well if it took 13 billion years to get to you then it's 13 billion years in the past
When you look into a Sun you see it as it was 8 minutes ago. Because it takes 8 minutes for light from Sun to reach you.
Many stars you see at night no longer exist.
When you see light from 13 billion years ago it's right here, right now, landing on your retinas.
@@mitsuracer87 ya well I DONT UNDERSTAND WHY THEY KEEP SAYING universe is expanding faster than speed of light HOWEVER in that case won't it mean we wont see the light of the stars??? Because how can we see light 13 billion years ago IF universe itself has been expanding faster than it????
@@kuochiangyuan6793 They're not really saying that, even if they do mistakenly use those words. What they mean is the space between objects is expanding and if you use two objects that are sufficiently far apart, the distance between those objects will grow faster than light speed. Two objects closer together than that though, will be moving apart at a correspondingly slower rate. The expansion of the universe is measurable and definable. When we measure it, we can define it as speed over distance. (According to the CMB, it is approx. 67.4 (km/s)/Mpc, with Mpc being a megaparsec or about 3 1/4 million light years) So, even over huge distances, the universe is expanding pretty slowly, it's only once you have added together an enormous amount of those distances(Over 4000 Mpc), that you get super luminal velocities.
Plus...
This expansion is cancelled out by gravity. You will hear of objects that are 'gravitationally bound', these are not moving apart. For e.g. All the stars in our galaxy are gravitationally bound and do not experience inflation wrt each other even though the milky way galaxy is something like 100,000 light years across. Also, the Andromeda galaxy is gravitationally bound to the milky way and is actually heading straight for us, Andromeda is something like 2.5 million light years away and the speed that gravity is pulling towards us easily outmatches the rate it's being pushed away. You can go even further out, the Virgo supercluster contains over 100 *clusters* of galaxies and stretches out over 110 million light years yet it is still gravitationally bound.
vacuum is a crystal. Unit of crystal is a only place where can be located electric monopole and the only place where magnetic dipole can't be located.
When magnetic dipole begins moving with arbitrary speed it enevitably encounter unit and will be broken to peaces ('+' and '-' electric monopoles)
wich immediately located in nearest units and connect thamselves to 4D( becase they are binary 1-digit number systems).
Then in 4D begins reincarnation of broken dipole.
Time depends only on distance between '+' and '-' electric monopoles. So reincarnated in 4D dipole continue moving untill next collision but at not arbitrary speed.
And i can't imagine other explanation why electromagnetic wave has no friction.
Visualize space as a medium like water .. Why ? Because it not only wraps around an object , but deflects in every direction of the objects shape. Take a sub. You can track it by simply measuring the displacement on the surface of the ocean. (Not easy to do & requires satellites). But in that way I think anyone can visualize space.
What if we aren't expanding and we're just being pulled by a bigger universe's gravity? Would explain the rate of expansion increasing over time?
Silly question.. I’m still learning physics.. what demarcates the boundaries of space as it expands? Thank you
Not a silly question. Not at all silly. In fact, I think u understood d question more than the guy in d vid.
Brian Keating really tryna get a laugh from a literal robot
Dr Keating ..If you had enough mirrors to reflect light at the speed of light… would light stand still or only appear to .. is perspective based observation ..reality to an observer .. also if u vacuum up space with a vacuum … which vacuum is real .. Dr Lex .. How do u feel emotionally about the fact that nothing is the absence of something … me ..I’m so lost in the most satisfying way 😃
Photons are ageless? Mind blown.
Thanks Brian K
@@DrBrianKeating ageless good, no suitcases better. Can you dad joke some ideas like space time = curvy quantum foam? The idea may not have validity in current models but introducing additional physics vocab is the idea behind my question.
Hi Brian. At around 1:51 you say a "serendipitous surprise" that the universe hasn't slowed in its expansion. Am I correctly inferring that you're implying that this is a good thing? Why is it serendipitous ?
Probably because it validates Einstein's cosmological constant term in GR, making Einstein and the edifice of GR even greater. That then obviously legitimizes the ongoing future use of his cherished Einstein thumb puppet, which he therapeutically manifests to make up for never being on the Muppet show as a guest star in *pigs in space* alongside miss piggy. Basically it's a sign that the universe is reassuringly deep down gloriously bonkers.....
i thought the observable universe was only 10-15 billion light years on each side?
The canvas is not expanding. The canvas of the universe is (for all intents and purposes) infinite. It’s what’s on the canvas that’s moving outward.
A better analogy I think is to imagine an infinitely large swimming pool. Drop a few plastic balls in there. What will those balls be moving into? More pool water.
The universe is not the nothingness between things. The universe IS the things in that nothingness.
"I grew up in the Soviet Union. We watched propaganda." LOL, Lex is great.
The Soviets weren't the only ones watching propaganda. ;)
@@kn0wmore126 He is now making propoganda.
“That’s any easy question”…a cosmologist assuming he knows what “space” is “expanding” into is like a virgin assuming he knows how sex is going to feel. 😂
Don't think of the universe as expanding into more of something. Think of the universe as being this thing that is constantly stretching itself :). This is why the theory isny called expansion its called Inflation! Becuase the universe is inflating not "expanding" :) ❤️
😂 he didn’t explain ish, he doesn’t really know. Einstein said “If you can't explain it to a six year old, you don't understand it yourself.”
The puns and casual joking while explaining something so delicately is unmatched
That Se7en reference was hilarious!! 4:45
The right question:
What’s the Universe Expanding Out to?
The universe isn’t expanding into a space that includes any matter though right? Will Your cm3 include any matter if it’s outside the universe ? … the matter in the universe isn’t anywhere except “in” the universe. So, what is the universe expanding into ?
Thanks but try again 😂
Leave it to Lex to ask about emotions when the topic is about pure science ... sigh
_"It appears that the universe is bigger than it is older"_
Buzz . . . category error.
You know someone is good at what they do, when they can explain it in many ways
Still no answer.....
@@bradash.9309I'm ctfu
A goldfish in a fish bowl will never discover the truth about it's distant surroundings or even make reasonable guesses. Are we so different?
According to the pre-roll commercial, it has something to do with Old Spice shampoo.
Lol
The universe is EVERYTHING. There is nothing outside of it because it's all encompassing. Now, if you're talking about our local universe (what we can see) the that's expanding into the part of the universe we can't see.
Technically true yeah. But still what is the universe that hasn't been expanded into yet comprised of? Yes, it's still the universe but what is there?
@@beeman4266 another way to say it, is that it's expanding into itself. Imagine a balloon and you're blowing it up, it is the universe, it just keeps getting bigger unto itself.
This is why they talk about "the big rip," because if you keep putting air into it, the fabric will tare apart. In theory anyway.
Great banter. I’m gonna watch the whole thing now (want to hear more on polarization and beyond).
Awesome. Thanks so much! *What was your favorite takeaway from the full conversation?* _Please join my mailing list to get _*_FREE_*_ notes & resources from this show! Click_ 👉 briankeating.com/list
Ooh! Brian did the space sample thing.
I always wondered (since I thought of it) what you'd find in a space sample. Like you bring a cylinder into space with open ends move it through the space and then close the ends and bring it in and analyze what's in there. I asked in some science group and they said nothing would be in there because space is a vacuum. Are you sure nothing would be in there? We're in there. Amebas and planarians are in there. Hmm. Still.
That's got to be one of the least convincing scientific aguments i've heard.
Brooklyn isn't excepted from expansion.
Lol. Thanks woody!!
….I’m laughing on the inside😂😂😂😂
As Terence McKenna observed, “Modern science is based on the principle: ‘Give us one free miracle and we’ll explain the rest.’ The one free miracle is the appearance of all the mass and energy in the universe and all the laws that govern it in a single instant from nothing.
The miracle is that there’s no miracle.
it's called intrinsic expansion, the universe isn't expanding "into" anything, it's expanding within its own confines. on a cosmic scale the distance between galaxies is steadily increasing, not just because the galaxies are moving away from each other (if they are), but because the space between them is itself expanding
If the universe is expanding..realize any dimension is a measured area of space that is occupied with matter..the supposed view of vacuum of space is no matter...m. he is explaining there are particles now that we are starting to understand and discover that occupy this vacuum..or dark matter of space....so...think of any expansion of a balloon..if it's flat
.it still has some air in there..some matter and particles...IF you blow more air in that balloon..the Ballon expands...and expands and expands with more matter expulsion..like a pulsar or nebular
It should become time people start saying: WE DON’T KNOW!!! If we can’t explain our own reality and consciousness then how would we know if what we are “measuring” even is correct??? Maybe it is all based on bullshit…
I wonder how much of this (if any) is easier to conceptualize at higher dimensions. If we could see time and space as an object the same way we can see a 1cm cube, how much further would the questions go..?
How far do you want to go?
Expand your conciousness enough and you will arrive to the questionless realm.
The universe operates like a toroid. Part is expanding, the other half is constantly contracting.
420 ... is it a coincidence, or the universe being a troll ?
Their math could be correct, but the information and their numbers could be wrong. Its not the first time reality has defied human computations
I’m not sure I followed the argument so well. I thought it was going to be a question of the “space” that spacetime exists in - sort of a spin on “where did the Big Bang take place[?]”. Or, “where is the Universe?” Well, it’s here… but where’s here? Maybe we say that the inflation of the Cosmos is the basis upon which any “here” could be - but that definitely seems to contradict the notion of a Multiverse. But regardless, is it meaningful to talk about a Universe coming into Being without conceiving of a meta-space of some sort that it came into? Seems like another “turtles all the way down” issue: wouldn’t we then need to explain how that space can exist at all too?
Ask a physicist what things do...and you will get a valuable education.
Ask them what any of the fundamentals are...that's quite a different 'matter' altogether.
Energy space time gravity...and the fun begins.
The smart ones will tell you in the end that they haven't a clue...the ones with 'egos ( the vast majority )
and you will be treated to an hour and a half of hot air...
To know the mind of man is one thing...to know the mind of God...that's above your pay grade and always will be.
Humbling ain't it...
Does this not mean, given that the stuff in the bottle exists inside the universe, that the universe is expanding into stuff which can be found inside the universe? How can that be because that stuff surely cannot exist outside the universe unless we are saying that the outside the universe is made of a vacuum just like the inside? If that is true then I have a mind blowing thought…. Just maybe the vacuum is STILL the outside of the universe and the universe is not expanding into anything, it’s expanding THROUGH it with both inside and outside co-existing in the same time and space with maybe another dimension, we don’t understand, providing the defining co-ordinate of uniqueness.
1. universe is the same size and everything moves towards the great attractor inside each universe -
2. there is no big bang but rather constant syphoning of all the matter back and forth -
3. anti matter is what keeps walls/edges of each universe sanitized of all organic matter build up -
4. dark matter is one of 3 main products of anti matter and dark matter keeps stars moving towards the great attractor -
5. there is no light speed nor light photons on their own - but rather when dark matter grinds against star's electromagnetic fields and such grinding produces extremely high frequency vibration waves that start to glow - and to us it looks like light - also keep in mind that when dark matter overwhelms a star by pushing the star to follow the path to the great attractor then star dies -
6. the reason why we have seemingly millions of stars is because the dark matter vibrates constantly - so when it bounces each star back into the path it creates a rotational field which is what we call a gravity - basically gravity is the force that dark matter uses against electromagnetic fields produces by every matter in space - but anti-matter is the king of all matters - it keeps the entire universe from exploding - like a soap bubble that is made of thin spider silk but as strong as carbyne -
7. dark matter is a child of anti matter - only anti-matter and the great attractor can destroy it -
8. all universes are connected via black holes, white holes, worm holes/tunnels - basically like doors between rooms -
9. no organic matter can pass any of those doors - but what is interesting that anti-matter can and the great attractors use it to renovate the universe's walls as well as to generate dark matter that clears universe from stars that dont follow the path to the great attractor, as well sanitize universe from any sort of organic matter build up including us -
10. each universe has its own great attractor - but it is more like the main battery for each universe to run - stars are just the electromagnetic juice to keep the great attractor alive - in other words each universe is basically a closed down garden of electricity, magnetism, polarity, organic/dark/anti matters - the light has nothing to do with anything as well as gravity - those just interpretations of the end result the dark matter causes to the stars -
11. every organic matter produces electricity to feed the electromagnetic field around itself - we call that aura - basically a word to name the same thing we call light or aurora borealis/northern lights - why can humans see northern lights but cannot see aura around another human - because of amount of electromagnetic waves that generated is only 100 watt - which enough to light a bulb daily - so now you understand why we are needed by the great attractor in the first place and how a simple organic build up (think of a biohazard mold) in space has evolved into a complex creature - we are all made of star particles and we all have one single purpose/job to do - is to keep the great attractor from dying - and we fail then the universe will be lost entirely - as for the anti matter, where does it go when the great attractor dies, cause we know that anti matter is needed by the great attractor - but when no great attractor left then what happens to anti matter (forget the dark matter as it forms into organic matter and gets sanitized via high voltage discharge from the great attractor) - the anti matter exists the universe via the black hole and syphons to a connected universe via the white hole - notice when it enters the universe it looks like a glowing smoke - there you go - that is anti matter that escaped from a dead universe that lost its great attractor or this universe where we are at is about to be sanitized from all organic build up - yes! sounds bad! but even a space mold (organic matter build up) restarts its build up eventually - as we are aware of so far 6 times such build up happened before on earth - in other words, earth is in out of reach by our universe's anti matter and its baby who's called the dark matter - but when a new batch of anti matter syphons into the universe the balance can tilt towards less room for organic matter what we call life - so less life and more anti life -
ELON causing irreversible changes in atmospheres
So if you was the only thing to exist in this universe you’d be able to travel infinitely in every direction into the empty eternal void, this isn’t nothing this is something. This also obviously means that it was eternally here but the question is how can this empty eternal void manifest a universe or multiverses when it’s eternal properties is emptiness?
P.S The universe itself can’t fill itself completely into every particle in this void as it’s expanding so it basically gets diluted in this 420 per square cm. As the universe ages, I’d assume this number will shrink due to the universe not having enough particles to fill the void it’s expanding in to, unless the particles themselves grow/duplicate at the same rate of expansion.
Space is Infinite
Space does not bend stretch or expand.
Only matter bends stretches and expands.
It is utterly ridiculous to say Space bends stretches and expands.
In my opinion "inflation theory" is the most ridiculous thing that I've ever heard because Space is already Infinite.
The Universe is expanding into itself because it is curved. There, I saved you a lot of gibbering. The best bit is that none of "the universe" it is really there. When you observe from outside of "the box", this becomes clear. The way to visualise it is: the empty space in between all of the stuff is pointing to that which is real. The stuff is just as empty as the empty space between it. You will see it.
"every cubic centimeter has Dark Matter Particles" - rrrrrrrrright. Tell them your discovery at the Hadron collider, they'd really be interested in how you detected these. smh
Cos space time probably folded so light distance isn't an accurate metric to measure how big the universe should be based on time since the big bang. It's too basic and doesn't factor in intense gravity folding space time
The 3rd rock from the sun? Wtf is that? The only fucking planet plan it I could from death back then live it.
My theory is something is pulling away the universe like a dot To a other dot the 1st explode and create an attraction to the other dot at any distance because something is connecting the universe toghether
you take a bomb, it explodes, matter travels away from the centre at extreme speed, how then does gravity have any effect on matter when in the vacuum of space, you would have thought that nothing should ever come into contact or be drawn toward any other matter because of this
This Might as well been in Portugese...I didn't understand a damn thing discussed here...back to the short bus for me
Newbs still think the universe is only the size of what is observed. History repeats, humanity thinks they're the center.
To say the universe is expanding in any sense is to posit an answer that is more complex than the question it's trying to explain, which is intellectually regressive.
Couldn't have been less clear.
These abstractions will get replaced with new abstractions in the future
It's not empty..lol. because a dimension is OCCUPIED SPACE
What if ☝
Everything, around the universe, is just getting smaller 😵🤯
The idea of a big bang to create the universe as we know it seems so ridiculous to me. That, and how was the Big Bang created? And what then created what created that?
The Universe isn't expanding. The Aether is shrinking which is local shrinking that shows up as red shift.
Sounds like he is saying that it's the aether inside the small box. Perhaps those photons are just there, and something at some point in time may excite those photons to create the light.
bigbang expanding.. expert after expert come out and tell this and that and nobody realy knows
But then how does the toroidal universe fit into all this? Isn't the universe basically proven to be flat
Photons don’t bring a suitcase with them, coz they’re a Fricking photon!
My brain nearly exploded, luckily for me I couldn't really grasp the full significance of the ideas.
The real question is this: If your brain exploded at the edge of the universe, what would it have exploded into? 😋

What does it look like at the edge of the universe? If you “teleported” to the edge, would you ride the wave of expansion and remain at the edge, or would you be surpassed by it instantly?
the "edge" of the universe (presuming you mean observable universe) would most likely just look like it does here for the most part. the universe is thought to be relatively uniform. You wouldn't feel like it's expanding any faster than you feel like it now.
You would still feel like you're at the center, more or less
If you teleported to the farthest reaches of the observable universe it would look much like it does here, but from your new perspective the Milky Way would then be at the 'edge', and looking in the opposite direction you'd see billions of galaxies that can't be seen from Earth.
Your question is a bit like standing on a mountain top and looking at the horizon and asking what it would be like to teleport to the horizon. Would you be at the edge of the world? Of course not, you'd just be however many miles from where you started and now the mountain would be on the horizon.
The wave of expansion permeates throughout the entire universe, its not localized anywhere.
@@nagualdesign that's only true in a closed universe . We can't be sure what shape it actually is
They gonna be so mad when they figure out space ain’t real.
New gravitational wave detector is coming online should shed some light 🕯️
WHATS IN THE BOX? lol Lex with the 7even reference
Space and time are the same thing they both measure distance and change can't have one without the other
so when deep thought said the answer to life the universe and everything was 42 um.
“We watched propaganda because im from Russia”, yeah unlike TV in America. Wow, another hot take by this “free thinker open minded facts and logic skeptic man”
It's 2023. Stop fat-shaming the universe!
Why is nothing expanding towards us faster than we move away.
Who is she to you in random thought just wondering. Lex and Brian
I have no problem meeting for classification of the situation within
But, Brooklyn is EXPANDING!!!
😮
We are all expanding every second, every minute, every day etc.
We are expanding our collective knowledge and our collective understanding.
Life on Earth has been expanding -“ knowledge and understanding “ -since the first organisms evolved.
If, intelligence continues to evolve for millions of years into the future in the same fashion that we have evolved in the past.
Then, those distant future intelligent beings will see us like we see single cell life forms from millions years ago, and so on, for example.
The above is self evidently obvious based on what we know now about the evolution of life.
We would be pretty stupid if we thought that it somehow stops at our intelligent understanding of the Universe today in 2023, for example.
So, however we perceive the universe now actually bears no resemblance to what it actually IS , if it actually IS anything at all.
Hope that makes sense.
Cheers.
What was before the Big Bang … that’s a question
The usual non-answer that the cosmologists and theoretical physicists give, is: "Nothing! Space and time did not exist before the Big Bang!".... which does nothing to answer where the singularity came from
" What is between those photons"
Great question, Lex.
Cosmologists should have been the first to escape chronocentric atomism, just as they once escaped geocentricism.
And they may well do so, if they can manage to avoid the error which physicists can't avoid: Taking tweakable mathematical models to be descriptive of mechanism.
Otherwise, Carver Mead, or some space scientists I have heard of will likely be first to glimpse the real mystery.
And thanks to Brian for being frank about the unknowns and not inviting woo into the discussion :)
"typical neurotic young Jew"
Love it 🤭
I truly can’t believe we’re still referring to gravity as a fundamental force, when it’s nothing but a reaction of space-time mesh/canvas being stretched by mass. Not only does gravity not pull anything, it also doesn’t act over any type of distance. Space-time is always pushing back to its normal point of least resistance, and any stretching dominoes for as far as the effect of the mass allows; which on galactic terms is an extremely far distance, especially when it’s magnified by all the individual mass forces that domino inside of galaxies.
I know this is kinda off topic, but I swear, if I didn’t look I would still be sure Dr Keating was interviewed by a well-done Jessie Pinkman.
Indians never had rockets. I was built to harness powers
It's funny, back in the old days they thought that the earth was the center of the solar system, and now we think the solar system is at the center of the universe
It's at the centre of the _observable_ universe. The entire Universe is probably infinite with no centre.
I find that watching these videos are interesting and does quench the thirst for knowledge but honestly, the academic level of mathematics is dropping so badly and we are given these super technologies to help these kids build lazy heuristics to work things out that they won't really understand, grasp or appreciate Physics properly without knowing and understanding the math.
For a second I thought this was Ben Shapiro again.
God. Say his name. I won’t be responding
don't waste our time. the crux to the headline question was simply, "it expands into nothing." Almost as absurd as the contention that the universe came from nothing. Get out of ere.
Serious shit if you want it to happen it helps. Unknown
Doesn’t it seem like our observable universe is in some sort of ultra massive black hole? They say the universe is expanding at an accelerating rate, but feels more like falling.
This has actually been defined as Black Hole Cosmology. It could fit with the Many Worlds Interpretation of quantum mechanics; each black hole produces a universe with even more black holes and even more child universes, leaving potentially infinite universes for all outcomes of the universal wave-function.
@@ronnyanddonny Oh awesome! I’ve always had the thought, but assumed it was out of my own ignorance. Good to have a name for the idea. Thanks!

"What’s the Universe Expanding Into?"
As long as there isn't a profit motive, this question is fine to ask
If every spot is the center of the universe from that frames perspective then every person is the center of the universe. When my penis accelerates in conjunction with the expansion of the universe. Is my penis therefore expanding faster than the universe is expanding?
Thanks Brian. I always love your articulate explanation of the cosmos.
