  • The flaw of the question is assuming there is a clear dividing line between species. Evolutionary change is a continuous process. We only have dividing lines where we see differences in long dead ones in the fossil record, or we see enough differences in living ones. The question has no answer, only a long explanation of how that isn’t how any of this works.


  • Correct, the differences make the analogy good enough to visualize the concept. It does however suffer from the same problem as the balloon one, in which someone can get the impression the expansion has a center. The wiki for the expansion of the universe goes through the various analogies and where they break down.

    I would suggest Dr Becky’s Youtube channel for a number of excellent videos on the expansion as well as the current problem of getting an accurate measurement of the correct Hubble expansion rate. The James Webb telescope was hoped to solve that dilemma, but we still aren’t sure.


  • At the cluster level it will depend on the velocities and distances. For example, using very rough numbers the current expansion rate means that space between us and the Andromeda galaxy is expanding at 55 km/s. Seems fast until you realize the distance needed to see the effect build to this level. For perspective I found someone’s calculation to reduce it to solar system level to end up with ~10 meters/AU/year. But of course at this distance gravity dominates so we can’t measure that directly and it may not even be large enough to consider.

    A larger and slower moving galactic cluster would be more affected than a tighter one. I don’t know what our Local Group would be considered to be, but there are a hundred or so galaxies around us that appear blue shifted, so they are moving towards us even with the expansion.

    Good visualization but inaccurate. Space between galaxies in a cluster and even the stars in a galaxy is also growing. The difference is in scale. There’s so much distance between galactic clusters and the largest structures of the universe that added up that expansion amount is so much bigger. The balloon analogy with galaxies as dots on the surface is closer since the dots also do grow some, but the balloon would have to be huge to capture a good scale comparison.





  • There’s a few videos on YT about him, particularly about his newest show and reintroduction to an unaware younger audience who isn’t familiar with his tricks. I’d suggest potholer54’s critique of the episodes, not only for breaking it down on why Hancock is woo crazy, but also reading the comments where lots of times you get defenders trying their own attempts of logic spin. It’s funny and sad at the same time.

    I hope Keanu isn’t a sucker about this stuff. I believes some of Hancock’s ideas too once, but to be fair I was like 11. I can only hope he was playing along and every time Hancock mentions a new fact Keanu goes “whoa…”

    We lost one early to kidney disease. One week he just started acting off, not eating normal, even found him hiding in places (which is never a good sign). Started losing weight visibly, so we got him in to the vet and the blood work comes back. We took him home for one last night together with the other cats before taking him back to let him go. Still rough to think about. We’ve lost a few others mainly to old age, which is still hard, but to cut a great companion’s life in half out of the blue…



  • The first Jurassic Park quote applies here, a few have used a variation of that idea of doing something just because you can. The other quote follows it, “Dinosaurs and man, two species separated by 65 million years of evolution have just been suddenly thrown back into the mix together. How can we possibly have the slightest idea what to expect?”

    These aren’t dinosaurs and are a lot closer to us in the timeline, but definitely reintroducing them in a large scale would have some effect to the environment they’re put in. Perhaps we only make a few…seems kind of pointless though to bring back a species but keep them at extinction levels. And can they even survive as they were in a warming planet? We might not even be able to, and we’re younger and current.








  • I tried it with my abliterated local model, thinking that maybe its alteration would help, and it gave the same answer. I asked if it was sure and it then corrected itself (maybe reexamining the word in a different way?) I then asked how many Rs in “strawberries” thinking it would either see a new word and give the same incorrect answer, or since it was still in context focus it would say something about it also being 3 Rs. Nope. It said 4 Rs! I then said “really?”, and it corrected itself once again.

    LLMs are very useful as long as know how to maximize their power, and you don’t assume whatever they spit out is absolutely right. I’ve had great luck using mine to help with programming (basically as a Google but formatting things far better than if I looked up stuff), but I’ve found some of the simplest errors in the middle of a lot of helpful things. It’s at an assistant level, and you need to remember that assistant helps you, they don’t do the work for you.
