I've been a big fan of science Youtubers for several years now. I even did a couple of blog posts on them in the past. PBS Spacetime was my favourite for a long time until they started running out of ideas. I discovered FloatHeadPhysics a few months ago and just decided today that Mahesh Shenoy is my new favourite science YouTuber.
I highly recommend any videos he has on special or general relativity. Mahesh is a superb communicator. He doesn't just explain the different phenomena; he strives to explain them in a way that makes them intuitive so they are not only easy to understand but they make sense as well. Before I watched his videos, there were some things I understood (or believed) intellectually but didn't understand (or know) in my heart. For example, gravity is sometimes explained by saying the earth is accelerating upward. I believed that because it's what the experts said, but it made no sense to me since the earth wasn't expanding. But I saw a video the other day where he explained it in a way that was intuitive and made sense. He made the light come on for me.
One of the first videos of his I saw was on the Twin Paradox. I had seen a ton of videos on this subject, and it seemed like multiple people gave different explanations. Most people resolved the paradox by pointing to the fact that the twin who left and came back had to experience acceleration when they changed direction, but Don Lincoln at FermiLab made two videos I found convincing arguing that acceleration had nothing to do with the solution. Then Sabine Hossenfelder (I think--my memory isn't perfect) made a video insisting that the solution involved acceleration, and Don Lincoln responded by saying, "We're basically saying the same thing," when they clearly were not. Well, I watched FloatHeadPhysic's video on the subject, and so far it was the best video of all the videos I've seen on the Twin Paradox.
Another science YouTuber I discovered since my last post on this subject that I wanted to mention because it's worth drawing attention to is Space Mog with Maggie Liu. She also has some excellent content and explains things really well.
Oh, and there's also GeoGirl with Rachel Phillips. I don't remember if I mentioned her or not. I got really interested in geology in the 10th grade. I've been insterested in astronomy for as long as I can remember, and my high school offered an astronomy class that was one semester. To take astronomy, you had to also sign up for geology for the other semester. I wasn't that interested in geology until I took the class. It was awesomer than I expected. It's been a long time since I've really gotten into the topic, but Rachel's channel has re-awakened my interest. Her videos are outstanding because she goes into a lot of detail and uses powerpoint.
