@astrumextra -- you work so hard for these visualizations, but I'm sorry to say I use these to fall asleep to. If you made audio-only episodes you could knock them out fast, and probably get quite a few views. Also I play each one several times, rewinding to the point I dropped off.

I love the fact that physics has to remain willing to surprise itself. Theories can be incredibly successful and still turn out to be incomplete when the universe gives us evidence we weren't expecting.

It's such an amazing channel ❤. Hat down to creators. Really great educational content 👌

Could the Hubble Constant have been getting quicker since the big bang? I'm thinking that the amount of localized gravity would have kept everything together for longer, (also possibly why Super Massive Blackholes formed earlier than seems reasonable), and as all galaxies are moving away from each other, their individual gravitational pull becomes less and less effective, allowing galaxies to speed up. Might even explain why you can't find dark matter or the dark energy we can't seem to detect, there simply isn't any such thing. Merely the ripples left in spacetime as galaxies go rushing around at ever increasing speeds, causing ever increasing ripples. Also if the light from the most distant galaxy has only just reached us here on earth, why to we need the JWST to look at it all the way out there? Absolutely love your show, I've never been so interested in space in my life thanks to Astrum.
