Why do we sleep? How do bicycles stay upright? Why does gravity exist? Wait...what do you mean you don't know???

For our 50th episode, we have a special topic - concepts that we don't fully understand yet! And why it's okay to say "I don't know".

Thank you for being a patron of Explain This for so long! We're looking forward to continuing to explain complex concepts in simpler ways for people of all ages. <3
