There are many YouTube channels that describe physics and cosmology, but by far the best that I’ve discovered is PBSspacetime. Things are actually explained, including the uncertainty principle, black holes, dark energy, and dark matter. It’s very interesting.
If you like biology, you may also be interested in PBSeons, and if you like random ramblings of history, language, science, and philosophy trivia, you might like Vsauce.
