Now when is the video coming explaining how to non-linearity of space results in the condensation of energy into matter?

@18:30 “If energy isn't conserved in our universe, then why does it usually seem like it is?
That's because when you're looking at the short timescales that we're used to, time translation symmetry pretty much holds.
An experiment done today will give the same results as the same experiment done …

We’d def have competed at the UBC Physics Olympics back in the day Derek. Congrats on an amazing journey and Godspeed - you make all us BC boys proud 👊

Surely then this means that momentum and angular momentum aren't conserved either? Even just by the symmetry argument, in a non-empty universe if you move a distance you could end up somewhere very different yo where you started.
If the balls slows down then its momentum must decrease, and the sam…

This serves to demonstrate my observation that when the universe acts in unexpected ways, we modify our math and say that it has always been that way, when we have no reason to assume that is the case.

this is what we're getting to? 'the equals sign' is algebra sort of implies that both sides have to be conserved. I've been saying for about a decade that we can't separate our mathematics from conservation because ALL SYMMETRY results from the equals sign. All mathematics result from the equals si…

I don’t think you explained you initial example with the rock stopping. You explained that energy would be conserved in an empty universe due to its time symmetry. In a non-empty universe the energy doesn’t need to be conserved, but where’s the proof it isn’t? And if it isn’t, why would the rock lo…

Thank you ! I had never heard of Emmy before , now i have another great example for my daughter

I know this may be nitpicky, but the way you say "Göttingen" or "Erlangen" sounds very off. I as a native German speaker would have trouble understanding the words hearing them alone without context.
Especially the way you say "Göttingen" sounds more like some word from Hungarian instead of German.…
