I'm no expert, but wouldn't it make sense that in a non-uniform expanding explosion, the densely packed areas would behave the way density behaves? If the universe expands over time, isn't it denser near the beginning, allowing large scale density events to take place early in time? Couldn't a dense universe have allowed supermassive stars to form that just immediately collapsed?
It's cool to discover it or anything else, but I'm not clear on why we should be surprised?
- falserum 3y agoNo expert either, but what you suggest is hypothesis. Article reports some new evidence that seem to support it. Not every seemingly obvious hypothesis is true. My personal favourite at-first-counterintuitive law of nature: in orbital mechanics, to catch-up, speeding-up does not work. Speeding up (1) changes the orbit, (2) elevates the orbit, (3) higher orbit has lower speed. (Excluding trivially close distances)
- dmix 3y agoSo how do you catch up then?
- abcrawf 3y agoSlow down and take the shortcut.
- bashinator 3y agoSlow down to get into a lower orbit, where you will overtake your target. Then speed up to get back into the higher orbit where the target will catch up with you.
