[@con.troller4183]

A key issue is identified in the first minute. We use the same word, "universe", for two very different things; absolutely everything and everything we can observe. If we let "universe" means everything there is, that leaves finding an agreed upon term for everything we can (or could possibly) observe from our location in time and space. That might indeed be everything there is but it is premature of us to say that, so until we know, we need new terminology to describe our local cosmos. Suggestions?

One thing is certain: we are surrounded by the Infinity... at our scale, at least!

[@Alejandro388]

excellent questions raised! If you're startled by vast proliferation of zillions of universes, do check out Max Tegmark's theory of mathematical universe. Then ask this question: why is there effectively an infinite number of prime numbers? According to Max, there's no fundamental difference between a mathematical entity like prime number a particular branch in the vast multiverse. Also, they are not "evolving" or expanding, inflating etc, to us time-bound creatures it just looks like they do, if for just a second you'd stop giving time-dimension a special role, then you'd realize that there is no movement, no evolution, no expansion, everything is "already there", nothing ever changes, like set of prime numbers. For you it may take centuries to calculate even a tiny fraction of that set, but the set already exists all at once all the time, it never changed one bit, never will. It's just our illusion of passage of time that puts enormous shackles on our power of inquiry and understanding of how things actually work or might work. Whenever such topics come up, i just referre people to take damn a serious read of Max Tegmark's groundbreaking work, and stop watching anymore of those speculations on YT

[@theuniques1199]

All numbers are infinite therefore the infinite moment and first moment are the same moment, zero can only replicate zero infinitely, you can't prove your first moment of existence therefore you can only prove your infinite point of existence which is always this present moment repeating itself as this present moment. History can only repeat history, infinite always first believes it is finite to realize it is infinite, repeat, infinite experience always first believes its eyes to realize its infinite experience, repeat. The Universe including humans as the Universe will never change but have always and will always exist as this same exact history of existence, repeat.

[@jareknowak8712]

[@innertubez]

Wow, mind-blowing episode! I wonder if this means that math is discovered, not invented? Or is it possible for a pocket universe to exist where 1 + 1 does not equal 2?

[@robbiep742]

Watch the "why anything at all" episode. In that episode, Max Tegmark explains that unlike objects we observe, math is not "created" but simply exists, making it more real than anything physical (quite the paradox). He proposes that we live in a mathematical object. The concepts of the laws of math are expanded on in many episodes, but there's a common thread in the philosophy of math that there can only be one way math exists. That it's a brute fact. Although a brute fact in the sense that if we have something rather than nothing, it's necessarily the math we know. An easy example - a circle's circumference. There's no way that it can be any other value. Try to imagine a square with more than four sides... it's not a square. With this explanation, 1+1 always equals 2, but it's possible that elements and compounds may have different properties, or the speed of light could possibly be something different ("fine tuning").

[@topguntk870]

What if other universes don't operate on any math, physics, or objects, but something else in its place which would be unimaginable to us in our universe? could there be universes where they have have something better then math? or completely alien concepts and ideas that we couldn't imagine? ill go as far to say not only are there illogical and paradoxical universes like where 1 plus 1 is 3 but even universes where numbers don't exist at all and theres something else entirely incomprensible in its place.

[@stephenzhao5809]

Alan Guth's theory of cosmic inflation is theologically based on Judaism, in particular, the interpretation of the first word, בְּרֵאשִׁית, of the first sentence of the first chapter of the first book of Bible. Hebrew 22 consonant letters are pictographic though it is an alphbet linear language as well. the letter, ב, a house or tent; ראשית, the head, chief leader, the subject, He, of the verb (בָּרָא) of the first sentence: בְּרֵאשִׁית בָּרָא אֱלֹהִים אֵת־ הַשָׁמַיִם וְאֵת הָאָרֶץ׃ JAB (Judism's translation): Within the Beginning, He (Ayn Soph) filled the powers (אֱלֹֹהִים), the skies and the land. KJV(Christianity translation): In the beginning God created the heaven and the earth. Obviously, according to JAB, the universe is defined as everthing including God, which means: He and His family all came out of the house, in contemporary cosmological term, Inflationary Big Bang. As mentioned in the post, The first resulted from Lucifer, who split from ONE (Deut 6:4), was a Fission Big Bang, simultaneously, got into NONE, and it was immediately disintegrated to the ultimate chaos (תֹּהוּ וָבֹהוּ, Gn1:2 KJV without form and void). Hebrew word, בֹּהוּ, is Emptiness, Nothing the Absolute as suggested by Hegel or in physical term, Vaccum the Absolute (Not Dirac Sea). Therefore, the first bubble from the Fission Big Bang, was absolutely isolated from God the Infinite, and immediately disintegrated to Lucifer dots (Ldot), the ultimate chaos, by Vaccum the Absolute according to the second law of thermdynamics set by God before the Beginning Time Point. In addition, Italian artist Michelangelo also supports that LORD God finished His 6-day creation through His words in His Original Bobble (the Original Universe) in The Creation of Adam en.wikipedia.org/wiki/The_Creation_of_Adam. Finally, LORD God Is Order the Extremely Asymmetric: He (extremely orderly beautifully) Exists (1) & He Doesn't Exist (0). Lucifer in follow his freewill broke the Original Order, and then a restoration of the original order was triggered, i.e. the six-day creation of LORD God. God is Love, who's given the freewill to all His Integral Components including Lucifer. Totally, there're three times LORD God directly intervenes Luccifer's work, the creation, the redemption, and the judgement. (Gn1,2; 1Jn3:6; Rev20:7~15) kzbin.info/www/bejne/gWPUn4efq7qYsJY Therefore, according to the theology of Christianity, black holes were created after Lucifer was absolutely disintergrated to Ldots. (Gn1:2; Is45:7). Genesis (1:6~8) simply describes how He creates heavens. Hebrew word, רָקִיעַ (Gn1:6) means sheet, אֲשֶׁר (Gn1:7) means cord, in the term of string theory, D-brane and string, respectively. May God bless you all. Amen,

The second way (different domains quizzed off from our regular space-time) is the most similar to biology, where a mother give birth to a child and the child then can create the next generation in what can be an endless chain of creation. Maybe this familiar natural chain of birth in biology, is a fractal that echo similarity to how the large scale of the multiverse behave.
