If you watch PBS Space Time from the beginning, it feels like Matt is constantly preparing us mentally for the episode where he tells us the Real Meaning of Life.

I have a PhD in physics. I teach physics in college. Despite all my experience, this video makes me rethink my notion of space and time. I love it. PBS Spacetime provides amazing contents that can be meaningful to all level of physics enthusiasts. Thank you to all the people involved in making those videos!

"The greatest trick PBS Space Time ever played was convincing the audience that space time doesn't exist." -Professor Keyser Söze

Your videos are so cool that whenever I watch them but get distracted by e.g., making a coffee for myself, I need to (I want to) roll back to rewatch parts of it, because I do not want to skip important parts, even though I had my earprohes on me the whole time. You make all seconds count. Full with vital information and useful explanations. Thank you!

We can't yet say Leibnitz is wrong. Lacking QFT and E=mc^2 he wouldn't know why, but his intuition was far more accurate than Newton's. Empty space and matter don't exist in the classical sense. And the only observable properties of spacetime are derived from excitations in universal fields that underpin matter. His theory holds up better than Newton's and will be a massive pain to disprove (if it's even possible)

When you realise that for a photon that has spent billions of years crossing the universe no time has passed at all. Then it starts to make you wonder what distance actually means, and if time, dimensions and mass only exist as a emergent property of objects traveling at less than speed of light. And then I go get a Gin and Tonic.
