Max Tegmark - How Vast is the Cosmos?

Everyone knows that the universe is huge, but no one could have imagined how staggeringly immense the universe, or multiple universes, may actually be. It stops your breath. How to get a measure of the size of the cosmos? What would it mean if the cosmos were literally infinite?

When I first read "Our Mathematical Universe" I threw the book across the room. Then I picked it up, and read it again and again. It's one thing to say our universe is "described" by mathematics, but to state that it "IS a mathematical structure" .. that was a shock. How Tegmark made the leap was just as shocking. I am assuming that he using the premise that ""All things being equal, the simplest solution tends to be the best one. Anyway I really am proud that there are physicists like Tegmark, Everett, and yes even Witten who are willing to risk their reputations on what might be dead end theories. But as a plea to all scientists, please leave out the word "infinite" . It is a sign that you have given up.

Personally I see mathematics as a language. It's a medium for expressing ideas and relationships very precisely. So to me a 'physical law' expressed mathematically is just a very precise description of physical relationships and behaviour. So I'm not at all surprised that mathematics is so good at describing physics. Since mathematics is a very precise, rigorous and consistent language all that means is that the behaviour of physical systems is very consistent. Well, I hope the universe behaves consistently. If it doesn't we're in big trouble. That doesn't mean mathematics defines that behaviour though. The behaviour comes first. The problem is of course we don't know why we see this particular behaviour, or why the particles and constants in physics are the way they are. Maybe maths is fundamental, but I don't think that logically follows from mathematics being good at describing the universe.

[@glaubs65]

Tegmark is suggesting that it is not just that maths is good at describing the universe, it defines the universe. [In other universes the defining maths (laws,rules) might be different.] What does it mean to say this? Does it mean that maths creates the universe, like a fractal? I have no idea.

This is why Religions are natural phenomena, because Man is an Intelligence with a Mind & Intellect .. to always deduced from OBSERVATION ... that anything that has purpose, form, function & design ... can only be made by an entity like Man (Intelligence). Science is a method of FUNCTION ... created by Man (a Function) ... to explain natural phenomena (functions) ... using fixed Laws of Nature(functions). The Scientific Method is: 1. Observe 2.

Everything is a NATURAL Function ... that must be made by an UNNATURAL intelligence.

In my humble opinion, you are quite right Simon.. The genesis of math is rooted solely in logical descriptors of our environment. Simple equations, however, have evolved beyond our ability to accurately clarify their meaning using any human language..The "Unreasonable effectiveness of math" is STILL a philosophical mystery.. Peace.

@@glaubs65 "Are numbers language? Is Sudoku a crossword puzzle?" Numbers are labels we use for various kinds of mathematical objects. Natural numbers, real numbers, quantities, elements of a series, etc. We actually use them in many different ways. I understand Tegmark's point, I think that when he talks about the unreasonable effectiveness of mathematics, I just disagree that this is evidence for his thesis. He might be correct, but I just don't buy that line of argument. That mathematics accurately describes the universe just means the universe is a consistent system, that's all.

Everything has to exist being supported by something other than itself. Therefore there cant be “ Nothing “ beyond the universe because the universe cannot support itself suspended by “nothing “.

Sort of like Hawking's "North of North." The question wouldn't make sense, but wouldn't there be required for there to be somthing outside the expansion even if immaterial? Because somthing can't expand unless it's expanding into somthing according to my understanding of Einstein's gravity physics etc. All this is exactly why I can't wrap my head around finiteness even moreso than I can't wrap my head around infinity. They're almost the same thing in terms of perplexity. But I say moreso because I can't perceive finiteness at all, I can perceive infinity however in tiny ways oxymoronically.

I think, in a very simple language, space refers to vacuum. So when the expression, "space is expanding" is used, I wonder, "Expanding to where?" When something expands, it displaces something or occupies a space that was previously unoccupied. So what is the expanding space displacing or what was the state of the unoccupied condition (or let me say "space" to which space is expanding? I think it is accurate to say the universe (the totality of matter and energy) is expanding rather than saying space is expanding. Space is an infinity therefore it is not possible for it to expand.

@@glaubs65 Something infinite does not grow or expand, it is already endless. Had the universe been infinite, it would not be expanding. For the fact that the universe is evidently expanding, it is clear that it has not reached infinity and will never reach infinity no matter how long it takes. At best, it will keep expanding for all future eternity. Infinite space (empty, dark, cold endless space) is ever there awaiting the universe's expansion. What lies beyond the universe is described in these words: "stars with no set course, for which the blackest darkness stands reserved forever." - Jude 13 in the Bible. Our mathematics for infinity is always going in the opposite direction. Instead of getting infinitely larger, it gets infinitely smaller. That being the case, we have to make a logical assumption: infinity is equal to one. With this assumption, all other things will be infinitely less than one but more than zero. That goes in line with our current mathematics where we easily get descending infinity.

I had first thought that Max Tegmark was totally out of his mind, but I am now changing my own mind, and am even surprised he didn’t double down on his last statement by highlighting this example: since Kantor first ventured into these treacherous waters, we now know that in mathematics there are different types of infinities and that there are infinities beyond infinities. Aleph-0, Aleph-1, Aleph-2,…, Aleph-Aleph-0, ad infinitum and beyond. At the same time, physicists are increasingly saying that the ultimate stuff that reality is made of is « information », aka math. So the next question must be: where does rationality, and thus math, come from? - remembering that « rational » comes from Latin « ratio » meaning calculation. Now that’s a question!! And what does it mean that we are able to have access to it? This echoes Einstein’s (was it he?) « What I find most incomprehensible is that reality is comprehensible ». That wonder-statement is perhaps the most baffling one I’ve ever heard. Thanks for this interview: I’d have liked to hear Max explain his views a bit more deeply.

1 + 1 = 2 IS NOT A GENERAL TRUTH. --------------------------------------------------------- If one ponders whether there exists any system of knowledge no scientist, philosopher, saint or whoever has ever disputed, then what comes immediately to anybody's mind is the system of arithmetic operations. 1 + 1 = 2 is often quoted as the best example of an undeniable absolute truth. But are these operational rules so certain? Consider the following observations: Imagine you add one heap (=lot) of apples to another heap of apples. Then you must write 1 heap + 1 heap = 1 heap In this case it is very right to say 1+ 1 = 1 Therefore the statement that "one plus one equals two" is only a conditional fact and not an absolute truth. Similarly also other rules of arithmetic. For example if you take two heaps of apples with two in each and two with three in each and make five heaps with two in each, then the statement 2 heaps + 2 heaps = 5 heaps, hence 2 + 2 = 5 is also correct. Have you ever seen even a single table of arithmetic operations, where it is mentioned that accuracy of these operations are conditional? On the contrary, the rules of arithmetic are often quoted as examples of "absolute truth" even by most stubborn philosophers. It is taught that different catogeries (or units) cannot be added (operated, in general), but here it is the same catogery (units) ~ "heaps" of the very same fruit, normally used to explain (prove) "one plus one equals two" ~ alone is involved. And when you add two cubes of sugar into your tea 1 +1 = 0 is also correct.

Idk

[@notyournickname]

LIGO detected ripples in space due to the collision of two stellar mass black holes! The method of detection is to measure the amount of compression of one of its arms (its an L shaped detector) by splitting a beam of light into the two arms, have them reflected at the ends, and then join them again. If peaks and troughs line up when joined - no gravitational waves, if they don't, that means the earth was ever so slightly compressed by ripples in spacetime.

There's something out there beyond what human can think. If there other universes then that implies divison so what's inbetween and what are they all contained in.

[@donlodge1230]

Great talk. Can somebody expain - how can the universe be infinite if it was created at the big bang. At which time it was presumably finite. How big was the universe when it became infinite? How can anything that was once finite ever be infinite? Sorry if this is a dumb question but I would love an answer.

[@grant1390]

There is nothing that says the initial state was finite.

Space is death and disease wrapped in darkness and silence. That is a great summary imho.

[@whitefiddle]

So! When he really wants to understand all of reality his first question is "how big is it?" That is just so precious! 🤣

[@supernova046]

is space itself static or does it move ?

The Earth isn’t even the equivalent of a grain of sand on the seashore,as opposed to the rest of the Universe. It’s mind boggling,to say the least.

[@NormYip]

To describe the fundamental structure of the universe as only mathematics seems close to the idea that we are a simulation. However if we are not a simulation, mathematics doesn't offer an explanation to consciousness.

5:26 Wanna know how big the universe likely is? 1. You know when we backup off the Milky Way and we see that we are but one squiggle of space in a river of flowing galaxies that curve and head down a drain towards the great attractor? Well, back off the camera as far as the eye can see. You’ll likely see a bubble. Something like a 3 dimensional race track. A bubble expanding and contracting like a vibration. We are so small it probably looks like it’s expanding. Those could be minor fluctuations. 😂❤

There’s lots of us that have been in the multi-verse. With a discovery of quantum entanglement the word universe does not apply anymore. It’s multi-verse.

The universe was not created using mathematics. We created mathematics to describe the universe.

Before you can tell the age of the universe you have to change your paradigm of what the living things are as stars and galaxies live and die.

Perhaps consciousness mirrors the universe and beyond, and maybe we should look inside for the answer.

[@chrispercival9789]

There's no reason to suppose in an infinite universe that nature hasn't tried every type of maths as a framework for a reality. I quite like the idea of evolutionary universes, each of which tries a particular framework of mathematics with an evolutionary tableau of natural 'constants', each in a dance between stability and dynamism

[@midnightroadstudios]

Its big, thats for sure.

[@rajendrareddy4150]

I have this question, is there an another universe which is closest to ours, and is expanding exponentially like ours? if it is so, is it possible that some of those other galaxies would encounter our outer galaxies? Thank you.

The Function, Intelligence & Mind CATEGORIES ... and .. the origin of all thermodynamic Systems(functions) ... proves God created Man in His likeness with a Mind that is natural ( Body) & unnatural (soul). There is only the Natural Universe .. that originates from & is expanding in ... an UNNATURAL System.

[@Bill..N]

It is an excellent question, friend.. One popular theory is exactly that..These "Bubble" universes are postulated to exist within a super space, sometimes called the BULK.. When collisions occur with adjacent bubbles (Universes), new universes are created from the resultant energy exchange..Peace.

If you can discover what meaning the word inverse has for you-could possibly have for you, you will see that another is gibberish or simple nonsense amnd woolly ,mentation, but you simply cannot discover what lies behind that word in your associative apparatus that is not just some vague generalisation

As usual on KZbin, there’s Dunning-Kruger effect in some of these comments. There is no way Tegmark could develop these ideas in a 14-minute video. Before criticizing them, may I recommend Tegmark’s book, The Mathematical Universe? I was a skeptic when I started it, but finished it convinced: Our universe is probably math.

If space is truly infinite than it would be impossible that we are alone.

[@MrS-pe6sd]

What else, in nature do we have proof is infinite? Nothing. So why would we assume, without any evidence that the space of the universe gets to break that rule?

[@reaganwiles_art]

When we say "Reality, all there is", size is meaningless. Where there is one, thus incomparability, dimensionlessness must be admitted. Relative size cannot be characteristic of all.
