Compton scattering Updated 2025-07-16
Classic theory predicts that the output frequency must be the same as the input one since the electromagnetic wave makes the electron vibrate with same frequency as itself, which then irradiates further waves.
But the output waves are longer because photons are discrete and energy is proportional to frequency:
The formula is exactly that of two relativistic billiard balls colliding.

Tetrapod Updated 2025-07-16
Includes:
- amphibians
- amniotes, which includes:
- sauropsida: reptiles and birds, which really are reptiles
- mammals
The exact relationships between those clades is not very clear as there's a bunch of extinct species in the middle we are not sure exactly where they go exactly, some hypothesis are listed at: en.wikipedia.org/w/index.php?title=Tetrapod&oldid=1053601110#Temnospondyl_hypothesis_(TH)

It doesn't need to be a bipedal robot. We can let Boston Dynamics worry about that walking balance crap.
It could very well instead be on wheels like arm on tracks.
Or something more like a factory with arms on rails as per:

How many Zettelkästen should I have? The answer is, most likely, only one for the duration of your life. But there are exceptions to this rule.

Goes along: if you could control your life multiple times to be perfect, you would eventually get tired of paradise, and you would go further and further into creating uncertain worlds with some suffering, until you would reach the current real world.
Very similar to The Matrix (1999) when Agent Smith talks about the failed Paradise Matrix shown at www.youtube.com/watch?v=9Qs3GlNZMhY:
Did you know that the first Matrix was designed to be a perfect human world where none suffered, where everyone would be happy? It was a disaster. No one would accept the program. Entire crops were lost. Some believed that we lacked the programming language to describe your "perfect world". But I believe that, as a species, human beings define their reality through misery and suffering. So the perfect world was a dream that your primitive cerebrum kept trying to wake up from.
