It's not really a topic everyone understands. The first time of hearing about dark matter was on this blockchain and its because I am a stem enthusiast. It means there are still a large number of users that don't even know anything about black matters.
Fyi: lemouth is a professor of particle physics and he's been working on dark matter for years. You check his blog to read about some of his research.
Thank you for the reference! I’ll check it out. I agree not everyone understands it. My wife gives me a glossy eyes stare when I talk to her about radiation exposure management at work. My sons though, one is two and the other is three, are getting early introductions into STEM. It can be fun if you let them have fun with it.
