    David is one of the best narrators of all time. Period. Especially if you're a science/space nerd. The "How Far Away is It" series is my favorite... I've probably watched every episode at least 4-5 times by now. Thanks David, for everything you do!

    Hi David, these medium/long format videos are my personal favourite in your catalogue work. I've noticed that your narration has changed over the years - does AI Tech help fill in the gaps when you aren't up to recording? Or has it been fully your own vocals on every single release? Keep it up!

    Would the dark ages really have been dark? Wouldn't there be a glow in every direction from the to-be CMB while it was still in the orange or red, as the light from that moment continued to reach a given point in space? When did the CMB first leave the visible spectrum?

    If* there was a 'big bang' and all matter stemmed from that and expanded from there on outwards, wouldn't all galaxies light have been visible on the voyage outward as space expanded and the galaxies were still forming, and not have arrived at their current positions and then emit their light back towards the inner universe? (Just a non astronomers dumb ass question) 😉

    I am making a world building project that's a sci-fi fantasy setting based heavily on native american myths but with heavy science grounding many concepts which is actually surprisingly easy cuz of things like Sundance religion of the great plains easy to connect to stars cosmological significance in science.
    Anyways one thing I added is a group of religions based on geometry of the universe with different sects believing that the universe is either infinite and flat like in 3d Euclidean geometry: they're called the Euclidians, and there are diverging sects who believe that it's either spherical and closes off from positive curvature and the others believe that the curvature is hyperbolic and negative.
    They treat figures of cosmological history the level religions do with saints and prophets. Their works are seen as scripture and to disagree is heretical. And my favorite aspect to write is their mythological history which is like a mythologicalized version of our real lambda cold dark matter model of cosmology. Like attributing the big Bang to a creator being. Attributing chaos, order, entropy and even geometry to deitys. And how the epochs of creation were the settings of epic battles between deities. I have a good myth about the first light of the universe being from the victory of the first sun gods (these specific deities in the setting manifested as stars and worshipped by regular ppl) over the deity of void, the deity of dark energy and some other gods I could associate with darkness.
    And just wanted to say your videos help alot with the cosmology because it's actually really easy to mythologize when you have someone remove the mythologicalizing alot of other narrators attribute and add. Or atleast it's easier to make my own mythos without being influenced by others. An example is SEA

    What about the CBMR axis of evil? How is it explained by the big bang? And if a big bang happened from a singularity then why are galaxies all moving away from each other and not from a single point in space? If we were to a thought experiment and reverse time, everything would originate from the supermassive black hole in the centers of each galaxy, not from a singularity, but everything appears to have originated from countless supermassive black holes scattered across the universe, each separated by millions of light years. Observations do not support a big bang singularity at all.
    Plus, according to the 1st law of thermodynamics energy and matter can't be created. Then why does the universe contains so much matter and energy if energy and matter can't be created? Observations indicate energy and matter can indeed be created else the universe would be a massive void of nothing. I wouldn't be sitting here made of matter and energy writing on a computer made of matter and energy, connected to an electrical outlet made of matter and energy, sending this information wirelessly thought the internet made of matter and energy.
    Plus, according to the lambda cold dark matter model, if a big bang happened 13.8 billion years ago, light takes time to travel so we're looking back in time, plus galaxies take a billion years minimum to form, then the JWST would not have found anything beyond the light distance of 12.8 billion light years away. Yet the the JWST and other ground based telescopes found old, not young but old galaxies, some older and larger than our own galaxy further than 13.5 billion light years away. Observations are empirical evidence which trump theories and speculation. Observations indicate the theories and models used to predict the evolution of the universe from start to finish are all wrong.
    Astronomers discovered old, fully grown galaxies further than a light distance of 14 billion light years away which debunked the big bang theory, rapid cosmic inflation, thermodynamics, speed of light, age of the universe, Hubble constant, theory of gravity, look-back time, distance to the CMBR and more.
    Keep on with the science fiction because it's a great story. Too bad Albert Einstein and others were found to be wrong. I feel so sad for Einstein because he wasn't the genius everyone portrayed him to be. I guess it's back to the drawing board with more ideas, assumptions and speculations.
