    A couple more for you.

    The scale I talked about for the size of the galaxy, which requires 120,000 years for a beam of light moving at the maximum physically possible speed through space, is inconsequentially small next to the size of the observable universe, which is 93 billion light years. Because the expansion of space isn’t limited by light speed, the relative speed of recession for far flung galaxies exceeds the speed of light.

    Here’s the kicker: as vast as the universe is known to at least be, there are more orders of magnitude to the smallest possible scale (the Planck length) than there are to the largest observable scale (the observable universe). The observable universe : us is not as large of a difference as us : the smallest possible scale understood by physics.

    There are four kinds of multiverses in the way that Max Tegmark breaks it down and I’ll summarize those when I have more time later.

    Think it, be it.

        Yep. I find this very interesting while comprehending very little at the same time.

            Here is Tegmark’s pop science article about multiverses: https://space.mit.edu/home/tegmark/PDF/multiverse_sciam.pdf

            Level 1: this is saying that the universe is likely to be large enough for a given configuration of particles in space to be infinitely replicated. So there would be an infinite number of copies of us, for example, across an unimaginably large swath of space and time. Anything that the laws of physics allows happens somewhere. Any possible configuration of particles within a given space happens somewhere. These would not be observable since they would be so far away and receding from us at over the speed of light—no signal could reach us. It is beyond our “cosmic horizon.“ while I think this is probable, it’s not testable and thus more philosophy than science, which is true of a lot of this. But there is reason to suspect it’s true.

            Level 2: the predominant theory for the formation of our universe is called cosmic inflation. This theory predicts that we are in one of a possibly infinite number of “bubbles” that form after a period of inconceivably rapid expansion of the universe. Each bubble would have its own physical constants and laws of physics. If there is an infinite number of them, eventually one identical to ours would be out there.

            Level 3: the most parsimonious explanation for the “weirdness” of quantum theory where a particle doesn’t have a position until it is observed is something called the universal wave function or the many worlds interpretation of quantum mechanics, versus the Copenhagen interpretation which says the act of observation somehow collapses a waveform of probably locations into a single discrete location. This interpretation basically says that all locations are valid, and that the universe splits in along every valid location.

            Level 4 gets into simulation theory and that we’re living effectively in a vast computer.

            I think 1, 2, and 3 are probably true.

            Think it, be it.

                        The beautiful irony of this is that it’s all an attempt at understanding something that our brains are not evolutionarily designed to understand. Humans are so obnoxious.

                            Contemplating the infinite and how inconsequential we are on the cosmic scale can both “blow your mind” and lead to existential dread. For me it does the former but not the latter. If anything it just makes me more grateful to be here for what time I have. There’s a great documentary about infinity on Netflix that touches on that. Even though there will never be a way to be sure about the various multiverses, I have reasons to believe at least in the first 3 I won’t bore you with and believe the 4th is possible. None of it makes any functional difference in how I live my life.

                            @Matt what’s cool about it other than a natural desire to understand how it all came to be is that this kind of exploration can yield valuable outcomes. Without quantum mechanics, we wouldn’t have microprocessors or be talking right now, for example.

                            But also yeah, shag off ya tossers 😂

                              I’m somewhere in the middle. More like existential indifference.

                                  One thing is for sure: If this is a simulation I want to thank whoever is playing me for discovering the IH part of the map. And so early too, great job!

                                    went on a short city trip to Heidelberg and amongst many other great things I of course visited the Castle to discover this massive wine cask which absolutely blew my mind!

                                    apparently a total of four versions were built, starting with the first in 1591 which was destroyed during the 30 years war to be used as fire wood

                                    in the pictures you can see the fourth version built in 1751 which can hold 220.000 litres of wine. I should say COULD as it was never really water tight and was only filled completely three times.

                                      Also reminded me of this at Champagne Pommery (a memorable feature of my first tour of champagne houses when I was about 7). This one holds 75,000hl (equivalent to 100,000 bottles).
