I found a pretty awesome youtube channel I wanted to share with you all.
It talks about things like black matter, universe theories, aliens, philosophy, etc. I find topics like this so interesting and if you do too check it out!
They also have German captions. I believe they are an automatic captions which aren’t always accurate but this guy speaks so clearly on this channel when I follow the captions its 99% accurate.
Thanks so much. On the same site are links to many series of science and maths videos for school students. Not only are they easy for me to understand, but I will also be able to use some of them with my German-speaking students next school year.
