best youtuber of all time: veritasium1/vsauce1
I put these guys in the same spoiler because they are basically the same, they even ask really abstract questions and use them as video titles i mean look at this

But they still make quality videos which are usually pretty informative or at least cool to watch so yeah they're the best

kursltkejiepjwiwerw - In a Nutshell
Seriously this name. These guys are similar to vsauce/veritasium except the narrators voice is AMAZING and the art direction is really fun. I think minutephysics could go here too but I prefer kaodkokorjoiw. These guys make videos on science but also politics and current events etc
