These Planets Are Inside a Nebula

I’d honestly be interested in knowing how circadian rhythms develop for beings living on a planet within a nebula where the sky is always bright. I would assume that they’d evolve in a way that there was some sort of internal clock but it would be much different than ours, which are brought on by day changing into night and our bodies knowing to produce melatonin once it’s dark. I suppose I’m also assuming that circadian rhythms would even exist on such a planet and that the lifeforms there — I’m aiming for sentient beings, obviously — have brains that require a total shutdown. It’s interesting to think about random oddball questions like that and I’ve probably got hundreds of them at the very least. Imagine meeting another species, though, that evovled in such a place and the first damn question you ask them — we’ll pretend here that we’ll be able to communicate and that they’ll understand what we’re even asking — is about something as simple and ridiculous as a circadian rhythm…

Realy I like this video so so much like you can imagine

Everything within life; has and is in fact; life. Kinda sounds self absorbed to say life can ONLY live when specific criteria have been met. Generally limits limit the creator of limits… friends would be nice to have, however.. but that; too is a “limit”..

this is all wrong. human eye are able to see the nebula, only change in the sky would be brightness of stars. nebulas are not dense at all and are easily blown by solar winds. What extreme conditions, what varying temperatures? terrible channel. just terrible
