Speaking of JWST, isn't the "''only a few stars, and probably no planets.''" just a nod to the fact that one of the missions of its infrared astronomy is to [[wikipedia:James_Webb_Space_Telescope#Infrared_astronomy|"see back in time to '''the first galaxies forming''' just a few hundred million years after the Big Bang."]]? i.e.: given the conical shape of the sector of universe covered by the pin-hole, most of the galaxies in it will be the furthest back, thus those of which we see the "oldest" picture and thus which much earlier in their process of forming stars and planets?

:Maybe but we cannot see them before the stars have formed and begun shining light. And by that time most of the planets would have formed. And also many many stars. So I do not think there is anything in the title text other than to make you think that what he says there is just plain wrong, and thus become even more overwhelmed! --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 13:43, 22 March 2022 (UTC) | :Maybe but we cannot see them before the stars have formed and begun shining light.

While space contains contains a vast number of things, it's still mostly empty. Like, on average, few atoms in whole square meter. Atoms of hydrogen, usually. Imagining so much of practically empty space is even harder than imagining all the stuff in it. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 05:50, 22 March 2022 (UTC) | While space contains contains a vast number of things, it's still mostly empty.
