least action principle and light speed limitation

Last updated on August 12, 2023

One science uploader I prefer talked about the principle of least action recently, which made me think about divergence and convergence in automatic control theory (you know I studied in automation department during my college).

Obviously, least action can always lead to convergence, which means only least action can allow this universe compute out valid results in time and the valid results can construct the presentation layer of this universe in time.

And also the speed of anything (information and matter) of presentation layer of this universe is limited by the light speed, which is at least for bottom layer can compute by a much much faster speed to construct the now and partial possible future of the presentation layer. For example, we know that the speed of the synchronization between entangled particles are much faster than light speed, so the entanglement must be a mechanism of the bottom layer of this universe.

This universe is exactly a computer which is just unimaginablly more complicated than any computer on earth. In another word, this universe shall be a creation which is created consciously and purposefully.

This let me think about the spontaneous and created existence: in this universe, how much of everything is naturally occuring? and how much of everything is created consciously and purposefully? I cannot know how much every specific existence is created or spontaneous, but I bet most miracles in this universe were created. Look around, on this earth of only several thousand years of civilization, how many miracles have been created by this humanity consciously and purposefully? Then you can imagine that in a universe created consciously and purposefully, how many miracles have been created in so many billion years?

/PS:

In path-finding problems, least action is just like least weighted distance which is always the most simple goal leading to convergence of a (oscillating) finding process and also is always the most cost-effective result of the problem. So it’s not a surprise that least action can be such a basic principal for this universe. And this is also like that in automatice control we try to find the way to control oscillating output to reach target value in a convergence most efficiently or quickly.

By the way, the creation of consciousness is numerouslly wider, deeper and faster than natural evolution or natural occuring, and we can see this just on this earth, right?
