Talk:2783: Ruling Out

Wow. the amount of citation needed tags is excessive. Here's a fun idea, do like that SMBC comic and actually find and give citations. 172.69.70.72 19:41, 31 May 2023 (UTC)Bumpf

Definitely. I fixed one (it should have been after the comma), during some other edits, but was sorely tempted to remove maybe two of them to just keep the funniest one(s). Whichever that(/they) might be. I expect they'll almost all evaporate in a future edit, though, as there's plenty of editting bound to be done. 172.70.90.219 19:47, 31 May 2023 (UTC)

I'm pretty sure there has been serious scholarship about the habitable zone of some quasars. Let's see.... Here: https://iopscience.iop.org/article/10.1088/1742-6596/2364/1/012057/pdf Not absolutely certain, but absolutely not ruled out. 172.69.134.24 20:02, 31 May 2023 (UTC)

I think that Cueball's scientific team did a study to discount the possibilities of quasars in the habitable zone of a star, not of a habitable zone around a quasar.172.71.166.249 20:52, 31 May 2023 (UTC)

A quasar could exist in the habitable zone of a star, and if it was particularly dim, it wouldn't make the zone inhabitable. There's no minimum brightness for quasars, is there? 172.69.134.162 20:54, 31 May 2023 (UTC)

I don't know how to properly describe the length of time the Moon's orbit of the Earth has been known. If you think that the moon orbits the earth, but you also think the sun, stars, and planets orbit the earth, do you actually have any way to justifiably say that you know that the Moon orbits the Earth? Also, is it worth pointing out the reasons that the moon is such an obvious thing to know about (i.e. its visibility and prominence to the naked eye, its cultural significance,...)?162.158.174.183 20:59, 31 May 2023 (UTC)
