Dramacels, !spacechads, what are some of the most ludicrous, possibly wrongful and reddity pop sci videos/channels you've come across?
My thumbnail example is a Kursgesagt video about Terraforming Venus.
I know they try to make it as “scientifically sound” as possible, but the whole idea sooooo incredibly far-fetched, it involves building giant planet size mirrors to cover sunlight from Venus so the CO2 in the atmosphere freezes, followed by harvesting nitrogen from Titan and removing all the frozen CO2. Not to mention water from Europan ice and another giant mirror to provide day/night cycles (as Venus is almost tidally locked).
Another is their Dyson sphere video
Which includes disassembling Mercury
They also have these pop physics videos where they try to convey some “deep” philosophical ideas like this one.
@Geralt_of_Uganda I remember you made a thread on them once

Also regarding Boltzmann brains
It's not taken seriously because it's more fit for a philosophy discussion, but in terms of feasibility it heavily depends on the assumption of the universe being ergodic (basically the assumption that every state of the universe/configuration of particles is possible to be reached). Now someone smarter than me could correct me on this because I suck at statmech, but I think the majority opinion is that the universe is non-ergodic and as such a Boltzmann brain might not be able to exist.
On the other hand if the ergodic assumption is correct and such a thing can exist, it still doesn't mean you are one. You'd have to compare probability of an ensembles forming a Boltzmann brain vs an ensemble forming... the world as we see and understand it, and while I've seen numbers thrown around to estimate the former, I have no idea how one would even go arround starting estimating the latter
