What the NEW black hole discovery tells us!

At the risk of sounding mean (I really don't mean to be) as a *science educator* I feel that she could do with slowing that speech down and seeming a little more serious. Basically like you would on a radio when lives are at stake. You'd be slow and deliberate wouldn't you. I really like her content but she seems to be in a permanent state of japery that just doesn't go with serious science educating. It makes it needlessly difficult to take in the information. And honestly, I don't mean to sound unkind. I like her and watch the content anyway. Does anyone else at least see what I mean there? She is much more deliberate in this video compared to normal and I find it helps a LOT with taking in complex information. There's just very little room for casual slang or talking as if you are talking to your friend in a high spirited fashion....
