The Exchanges

Every argument clarity score on this site is built from rows on this page. Each question and answer was assessed with names hidden, the host's own answers included, on four things from 1 to 5: directness (does it answer the question asked), coherence (do the ideas follow), precision (concrete details and clear references), compression (says a lot per word). The weighted mix (30/30/25/15) is the exchange score. A person's published score averages their exchange scores on raw tape only, at least 8 of them, shrunk toward the cohort mean. Full method →

Alex Filippenko no published score: only 2 usable exchanges on raw tape, and a fair score needs 8+ record → ← everyone

Every exchange below was scored with names hidden, four dimensions each from 1 to 5. An exchange's score is 0.30·directness + 0.30·coherence + 0.25·precision + 0.15·compression. The published score averages the raw tape exchange scores and shrinks small samples toward the cohort mean, so five great answers can't beat twenty good ones. Produced feed rows count only toward coarse estimates, never toward a full score.

Q responsible or account for what we see is what's called the cosmic microwave background radiation, which may mean that the, what we assumed was coming from the early universe from the big bang may actually come from these galaxies. And it's like, do we have it all wrong? We may. And these papers are getting a lot of attention. Is the bank big bang theory disproven now with this discovery?

A The Big Bang theory is on, is on very solid ground. There are many details we don't understand. The basic tenets, however, of the theory are just threefold. The universe long ago was hot, it was dense, and it was expanding. Nothing in those studies contradicts any of that. As I mentioned, the early formation of galaxies is an interesting puzzle. It means that Our understanding of how galaxies formed and evolved is still incomplete, but that's part of the fun of doing science. There's new things, you know. The cosmic microwave background radiation is the, the afterglow of the Big Bang, and it turns out it agrees to very high precision with a very single temperature, meaning that the universe everywhere was the same temperature, then expanded by the same amount, and we see, see the same temperature everywhere. There's no way you can do that With galaxies forming at a range of times and distances, they would each contribute light that would not give this so-called black body thermal spectrum, and there are many other details of the microwave background, the spots and stuff that are not at all addressed. So a lot of these theories, you know, as scientists we can dream up things, and we just kind of put them out there to be explored more, but of course the media likes to highlight the, the really snazzy sounding things, and so Sometimes, often, the very speculative ideas get way too…

Q Therefore, is the expanding universe that we see our version of being inside of a black hole, which is effectively an accelerating contraction towards the singularity?

A Yeah, so, Um, what David is referring to is that if you look at the mathematics of a black hole, from our perspective, what we call space and time outside reverse their meaning. Um, time becomes space and space becomes time in terms of directionality. So for example, if you're in a black hole, there's no way you can avoid the so-called singularity where you get squished into nothing because it's in your future no matter what you do. Now, applying that as you wanted to do to the whole universe, I don't think that the correspondence is such that the expansion that we see is the reversal effect of, um, this, um, going toward the singularity because, uh, well, because of some technical issues. Again, if you look at the mathematics, there are some interesting correspondences, but they shouldn't be taken too, too literally in most cases. Yeah.
