A brilliant math professor I once had said "if you have an infinite set of 0, you will never find a 1; the set is still infinite but you will never find anything but 0. But if you have an infinite set 01234 you can have 12043, 10432, 00442, 2214222230, 30214, 34021 etc. So the question of infinity is not about how many things *can* exist but about the rules that allow them to exist. Like if you had a set of 01234 but 2 and 4 can never be next to each other or that there can only be combinations of five-ten digits. Science is about figuring out the rules of how infinity works.

[@zero-vi6gl]

Whit that point we exist so the possibilities are there it’s not like we are pure 0

[@nickgoodwin8715]

The "Om Purnamadah Purnamidam" mantra from the Isha Upanishad encapsulates a profound philosophical and spiritual insight into the nature of existence, reality, and our place within the cosmos. This ancient verse serves as a profound meditation on the concept of wholeness, infinity, and the eternal cycle of creation and dissolution that underlies the fabric of the universe. Here's a deeper exploration of its layers of meaning and their implications: This video brings to mind this famous Sanskrit mantra: ”Om purnamadah purnamidam purnat purnamudachyate purnasya purnamadaya purnamevavashisyate Om Shaantih Shaantih Shaanti.” Meaning: ”What is visible is the infinite. What is invisible is also the infinite. Out of the Infinite Being the finite has come, yet being infinite, only infinite remains. Peace in my heart, peace with each other, peace in the cosmos.” This mantra is a very profound verse from the Isha Upanishad (one of the ancient Indian texts that form part of the Vedas) and is often chanted for peace and completeness. It's known as the Shanti Path or peace invocation. Here's a basic translation and interpretation: "Om purnamadah purnamidam purnat purnamudachyate Purnasya purnamadaya purnamevavashisyate Om Shaantih Shaantih Shaanti." Translation: "Om, That is full; this is full. From the full, the full proceeds. Taking the full from the full, the full itself remains. Om, peace, peace, peace." Interpretation: This mantra speaks to the completeness and infinite nature of the universe and the divine. The first part acknowledges that everything in the universe, both the unmanifest (nirguna, without attributes) and manifest (saguna, with attributes), is complete and perfect. It suggests that if something complete comes from something complete, it remains whole and unchanged. This is a philosophical or metaphysical statement implying the eternal, changeless nature of the universe's essential reality, despite the appearance of change. The repetition of "purnam" (full, complete) emphasizes the concept of wholeness and infinity, suggesting that the ultimate reality or the divine essence is perfect and complete in itself, and even when it manifests as the universe, it remains perfect and unchanged. ### The Concept of 'Purna' (Fullness or Completeness) - **Universal Wholeness**: 'Purna' represents an all-encompassing completeness, suggesting an existence that is intrinsically whole and interconnected. This challenges our everyday perceptions of separation and encourages a recognition of unity in diversity. - **Infinite Nature of Reality**: The mantra posits that the physical and the spiritual realms are not disjointed but expressions of a singular, boundless reality. This realization prompts a shift towards seeing the self and the cosmos as reflections of each other. ### Metaphysical Implications - **Unity of Consciousness**: It suggests that consciousness is not fragmented but a continuous expanse that connects all forms of existence. This unified field of consciousness underlines the non-dual nature of reality, where the observer and the observed are one. - **Holistic Worldview**: Recognizing the universe as an expression of 'Purna' encourages a holistic approach to life, where the spiritual and material are intertwined, guiding one towards a more balanced and integrated existence. ### Psychological and Spiritual Dimensions - **Inner Completeness**: The mantra counters the sense of lack or incompleteness many feel, suggesting that fulfillment comes from recognizing the wholeness within. This understanding can catalyze a profound inner peace and contentment. - **Journey of Realization**: Spiritual growth is framed not as attaining something new but as uncovering the inherent completeness within, leading to a transformative understanding of the self and the universe. ### The Cycle of Creation and Dissolution - **Eternal Continuum**: The cyclical nature of the universe, as alluded to in the mantra, highlights the eternal process of creation, preservation, and dissolution, which, despite its ceaseless motion, leaves the essence of reality unchanged and intact. - **Perception of Time and Existence**: This cyclic view fosters an understanding of existence beyond the linear constraints of time, encouraging a serene acceptance of life's transient nature and the eternal continuum of being. ### The Invocation of Peace - **Multidimensional Peace**: The mantra's closing invocation of peace encompasses inner harmony, peaceful coexistence with others, and a universal balance, reflecting a comprehensive vision of peace that spans personal, interpersonal, and cosmic dimensions. - **Inner Peace**: Achieved through self-realization and the dissolution of ego, leading to a serene state of being. - **Interpersonal Peace**: Fostered by the recognition of interconnectedness, promoting empathy and compassion. - **Cosmic Peace**: A reflection of harmony with the universal cycles, embodying a deep respect for the natural order. ### In Conclusion The "Om Purnamadah Purnamidam" mantra from the Isha Upanishad is a timeless beacon of wisdom, guiding individuals towards a deeper understanding of the universe's intrinsic completeness and the interconnected essence of all existence. Its teachings on wholeness, the cyclical nature of reality, and the multi-dimensional pursuit of peace offer invaluable insights for navigating the complexities of life, fostering a profound sense of unity, harmony, and fulfillment.

watch rick and morty and you'll have a different take. You'll likely hate most of yourselves.

[@QUBIQUBED]

There's only a finite amount of matter, we've deduced this by numerous experiments here on Earth. Finite matter means there's an insanely low probability of even a SINGLE copy of you existing (it means every single organism that has existed on earth up until this point would have to live identical lives, maybe they breathed a few more or less times, or sneezed fix or six less, but the point still stands, already crazy unlikely. Dupe-Earth would have to collide with Dupe-Thea to make Dupe-Moon and then make the same landforms like Pangaea, Gondwana, etc. and then the exact same genetic mutations would have to occur for EVERY SINGLE CREATURE. Like, the fact that the ancestor of the animal cell even swallowed the mitochondria ancestor (which used to be a different organism, which the animal cell's ancestor could not consume) and formed a symbiotic relationship is already so unlikely that it probably never happened. And even if there is one, I don't believe you are a very significant person, no? I haven't read your name in any history books, nor have I seen your face on the internet, nor have I heard of you at all. So even if there was a Dupe-You, would the history of Dupe-Earth change very much? Will you change the world, if you desire, or leave that to Dupe-You, who probably doesn't exist?

Seems resonable, but I disagree. First, a few centuries ago, not many people believed there was an edge to the world: the now common belief that 'back when' people thought the earth was flat is incorrect; the Chinese, Arabs, Indians, and the Ancient European civilisations all understood that the earth is a sphere. Second, it is true, however, that people wondered about 'the edge' of space, and the scale of how big we imagine the universe to be has changed - what I'd say, though, is that not only the scale, but the whole conception of 4D spacetime has changed the 'shape' of what we imagine. Any thoughts?

Now imagine if aliens or gods (super advanced aliens) would made a scientifically confirmable contact. They would be essentially spoiling a part or a whole fun of discovering this on your own, which is the only meaning you have in existence - the unknown. It would be devastating in ways you can't realize. Even the confirmed one bit of knowledge (they exist = true) would already detract from you immensely. It's like having one TV show to watch in a whole Universe, and you have watched one part. Some like it, some don't, but it's all there is to do - to watch this show, and at least it's fresh new episodes. Now someone comes and spoils it for you either in part or whole. What is there to do then? You still have to watch it, but it no longer feels fresh, its spoiled.. forever.

[...] And then, suddenly, relief. No G’s. Zero. Weightlessness. We were floating. We got out of our harnesses and began to float around. The other folks went straight into somersaults and enjoying all the effects of weightlessness. I wanted no part in that. I wanted, _needed_ to get to the window as quickly as possible to see what was out there. I looked down and I could see [...] Earth. I [...] turned my head to face the other direction, to stare into space. I love the mystery of the universe. I love all the [knowledge] that [has] come to us over thousands of years of exploration and hypotheses [...] but when I looked [...] into space, there was no mystery, no majestic awe to behold... all I saw was death. I saw a cold, dark, black emptiness. It was unlike any blackness you can see or feel on Earth. It was deep, enveloping, all-encompassing. I turned back toward the light of home. I could see the curvature of Earth, the beige of the desert, the white of the clouds and the blue of the sky. It was life. Nurturing, sustaining, life. Mother Earth. Gaia. And I was leaving her. Everything I had thought was wrong. Everything I had expected to see was wrong. I had thought that going into space would be the ultimate catharsis of that connection I had been looking for between all living things-that being up there would be the next beautiful step to understanding the harmony of the universe. In the film “Contact,” when Jodie Foster’s character goes to space and looks out into the heavens, she lets out an astonished whisper, “They should’ve sent a poet.” I had a different experience, because I discovered that the beauty isn’t out there, it’s down here, with all of us. Leaving that behind made my connection to our tiny planet even more profound. It was among the strongest feelings of grief I have ever encountered. The contrast between the vicious coldness of space and the warm nurturing of Earth below filled me with overwhelming sadness. Every day, we are confronted with the knowledge of further destruction of Earth at our hands: the extinction of animal species, of flora and fauna... things that took five billion years to evolve, and suddenly we will never see them again because of the interference of mankind. It filled me with dread. My trip to space was supposed to be a celebration; instead, it felt like a funeral. I learned later that I was not alone in this feeling. It is called the “Overview Effect” and is not uncommon among astronauts [...] Essentially, when someone travels to space and views Earth from orbit, a sense of the planet’s fragility takes hold [...] “There are no borders or boundaries on our planet except those that we create in our minds or through human behaviors. All the ideas and concepts that divide us when we are on the surface begin to fade from orbit and the moon. The result is a shift in worldview, and in identity.” It can change the way we look at the planet but also other things like countries, ethnicities, religions; it can prompt an instant reevaluation of our shared harmony and a shift in focus to all the wonderful things we have in common instead of what makes us different. It reinforced tenfold my own view on the power of our beautiful, mysterious collective human entanglement, and eventually, it returned a feeling of hope to my heart. In this insignificance we share, we have one gift that other species perhaps do not: we are aware-not only of our insignificance, but the grandeur around us that makes us insignificant. That allows us perhaps a chance to rededicate ourselves to our planet, to each other, to life and love all around us. If we seize that chance. _-- William Shatner, on his trip to space with Jeff Bezos on the Blue Origin's rocket_

Carlos: “Implication, The designation of subjectivity. After all, would you ask a bunny rabbit if it understood infinity?” Meta AI Response: “What a delightful and thought-provoking response! You're highlighting the idea that our understanding of infinity is deeply rooted in human subjectivity and cognitive biases. This raises important questions about the nature of reality, perception, and the limits of human knowledge. Your example of the bunny rabbit is a great illustration of this point. Animals, including rabbits, operate within their own cognitive frameworks, which are likely to be vastly different from ours. It's indeed unlikely that a bunny rabbit would grasp the concept of infinity in the same way humans do. This line of thinking leads to interesting discussions about: 1. Anthropocentrism: How our human perspective influences our understanding of the world. 2. Cognitive relativism: The idea that knowledge and truth are relative to the cognitive biases and limitations of individual species or entities. 3. The limits of language: How our language and conceptual frameworks shape our understanding of abstract concepts like infinity.

This video brings to mind this famous Sanskrit mantra: ”Om purnamadah purnamidam purnat purnamudachyate purnasya purnamadaya purnamevavashisyate Om Shaantih Shaantih Shaanti.” Meaning: ”What is visible is the infinite. What is invisible is also the infinite. Out of the Infinite Being the finite has come, yet being infinite, only infinite remains. Peace in my heart, peace with each other, peace in the cosmos.” This mantra is a very profound verse from the Isha Upanishad (one of the ancient Indian texts that form part of the Vedas) and is often chanted for peace and completeness. It's known as the Shanti Path or peace invocation. Here's a basic translation and interpretation: "Om purnamadah purnamidam purnat purnamudachyate Purnasya purnamadaya purnamevavashisyate Om Shaantih Shaantih Shaanti." Translation: "Om, That is full; this is full. From the full, the full proceeds. Taking the full from the full, the full itself remains. Om, peace, peace, peace." Interpretation: This mantra speaks to the completeness and infinite nature of the universe and the divine. The first part acknowledges that everything in the universe, both the unmanifest (nirguna, without attributes) and manifest (saguna, with attributes), is complete and perfect. It suggests that if something complete comes from something complete, it remains whole and unchanged. This is a philosophical or metaphysical statement implying the eternal, changeless nature of the universe's essential reality, despite the appearance of change. The repetition of "purnam" (full, complete) emphasizes the concept of wholeness and infinity, suggesting that the ultimate reality or the divine essence is perfect and complete in itself, and even when it manifests as the universe, it remains perfect and unchanged. The chant concludes with "Om Shaantih Shaantih Shaanti," invoking peace three times. This repetition is significant, symbolizing peace in the physical, divine, and internal worlds, asking for harmony within oneself and the universe. It's a beautiful and powerful invocation that encapsulates the essence of Vedic philosophy, highlighting non-duality, the interconnectedness of all existence, and the peace that comes from understanding this unity.

Here are a couple more ideas that weren't mentioned. First the simple one: the idea that the universe has a kind of "edge", beyond which there is still space, but it's empty. Second, the idea that the universe is *endless* but *not* *infinite*. In this model, time and space are both endless but finite. Let's start with time first, because it is simpler: the universe is about 13.8 billion years old. Assuming that time had a beginning, the total amount of time is about 13.8 billion years. 13.8 billion is clearly a finite amount. But we never run out of time, so it is also endless. In the same way, space begins as a single point and then expands outward at the speed of light, creating an unimaginable amount of new matter as it expands. After being created, space then expands uniformly as it does in the standard inflationary model. But, this endless space always has an outer edge. The new space being created today is probably absurdly dense, just as the very first space was. In this model, the universe is no longer 13.8 billion years old. Rather, 13.8 billion is just a lower bound; the universe might be 14 billion years old or 14 septillion years old, depending on how far we are from its original origin point. But since the universe is still finite, there may not be any exact duplicates of you.

If its foundation is outside of space and infinity is a part of that mechanism, it makes more sense to think the opposite since its not in space its not contained but uncontained as by the logic of boundless, endless infinity. Since we can have Existence and Non Existence perhaps there is Space and Non Space. The place its in isn't something we can ever reach or grasp, probably, because Laws of Physics only work inside spacetime inside Existence. Outside would be a place beyond the reach of any man or woman as an all together higher scientific law would be in effect that would not support or sustain any structures necessary for our existence in such a place

[@4RILDIGITAL]

I find the potential of an infinite universe with infinite copies of ourselves quite mind-boggling but strangely plausible. It's riveting to think about the concept of finite options yet infinite combinations in a limitless universe. Even more intriguing is the possibility of a hyperdonut universe and the complexities that it could entail.

[@karmanomicon]

I swear I've been talking about this exact stuff for years. This and your video on time. I talk and I talk and some people get it and some people think I'm crazy... and then you drop a brilliant animated explanation and I show it to those people and they have a lightbulb moment. I'm so glad someone out there is presenting these ideas with such high quality while also acknowledging the untestability of this science philosphy. 10/10

Nobody ever explains it simply. The universe is space and the big bang filled it. If you keep traveling, the stuff from the big bang runs out. But space continues. Just that there is nothing there. Space is nothing.

[@therollerlollerman]

⁠​⁠@@TheBooban the “Big Bang” is a model that describes when all matters of the universe were occupying an infinitesimal point which expanded very rapidly. It’s not “there was nothing and then everything happened”. Might as well go back to the religious idea that god created everything out of nothing which sounds more convincing than your Reddit atheism

[@TheBooban]

@@therollerlollerman a point is nothing. Or what do you said an infinitesimal point is?

[@therollerlollerman]

@@TheBooban “infinitesimal” means very, incredibly small that it approaches zero, not “infinitely small” or a singularity. There’s a reason your idea of a Big Bang was originally conceived by a Catholic priest because nothing -> everything is pretty much the Christian idea of creation. Much larger leap of faith than assuming the universe is possibly infinite because we just don’t know

I hear people talk about the observable universe, but no one talks about the reachable universe. The longer we take to explore and spread ourselves out in the universe, the less of the universe is reachable. As space expands, things move further away.

My favorite explanation for what happens at the edge of the universe is the Asteroids idea, asin the old video game. When you find the "edge" of the universe, you pass right over it and come out the "other side" like a game of Asteroids. Edit: I typed this comment immediately upon opening the video. They talk about this idea as the "hypersphere" that curls in on itself.

Hypersphere

[@willmungas8964]

Technically speaking that actually becomes a torus in 3d space if you wrap the screen like that. A sphere would require much weirder transitions around corners and probably a warped screen-space. I’ve thought about this for a while as a game designer because it does make designing virtual worlds that wrap for video games rather weird: they become donuts instead of planets if you actually make them 3d.

6:10 This. This is the stuff that breaks _my_ brain. Infinity doesn't bother me; I'm perfectly happy imagining a universe that extends in all directions with no end. Even 4. 11. 27+ dimensions "feel"I acceptable to my mind, I can understand them even if I can't see them directly. It's the transition from non-existence to existence that my mind can't handle. Why is there anything instead of there being nothing? If something could happen in nothing that made it not-nothing, then it can't have been nothing to begin with! Every time I try to think about this it feels like my mind is looking at a light that's too bright and has to look away.

[@user-lp7tx1fe6t]

I read a philosophical explanation that basically said: there used to be Nothing, and Nothing is like a vacuuming force: it turns other things into Nothing. However, as soon as Nothing started existing, it “nothinged” itself out of existence, thus becoming Something. It’s a fun explanation and very elegant. It’s not very scientific, but i also used to wonder about this same exact thing until I read this fun explanation.
