I just found this video: with the name "Dark Matter Mystery Finally Solved, and It's Simple?!" (it has more than 7000likes and about 75 dislikes) . The problem here is that it's the first video that pops out when you write Dark Matter in YT search and it's not the only one of this type. Recently I've seen hundreds of videos like this where people with 0 understanding in Physics talk about speculative ideas or ideas that they didn't even understand. I think the idea of real physicists popularizing science is good but i think that people that are not physicist should not wave hands and advertise wrong/unproven/misunderstood information. What do you think about this?
