Will Constructor Theory REWRITE Physics?

Check Out American Voices: Keep it Close: • What a Small Gift From...
The people behind the greatest leaps in physics - Einstein, Newton, Heisenberg, all had the uncanny ability to see the fundamentals - see the deepest, underlying facts about the world, and from simple statements about reality they built up their incredible theories. Well what if we all had a recipe book for doing exactly this. Well, one might be just around the corner and it’s called Constructor Theory.

Teaching bleeding-edge science to a general audience (me) without making it feel watered down is done nowhere else as well as here. Thanks to all involved.

"Be careful! The devs WILL notice." - This has got to be the funniest yet most existentially disturbing reply ever made on this channel.

Years ago, I was a physics major. Life didn't turn out the way I initially expected and now I'm in CS classes, including Theory of Computation. This video is very much the intersection of stuff I've studied/studying and hits hard.

So if I understand Constructor Theory correctly...

Rough shade on Newton with that whole "you can't transmute apples into gold" line

@deitylink1 2 роки тому

Wouldn't constructor theory fundamentally be assuming we know all the base sets of rules in order to be correct? Otherwise it could rule out things that are possible, but they just don't have a truth statement for in the base set of rules.

I sleep with your astrophysics theories & videos. Well, this has been my Naptime channel. Whenever I feel stressed or a need for nap, I watch this. Love from India 🇮🇳

The Devs already noticed, and they're literally making things up for us to measure.

I watched a lecture right here on UKposts about this topic, and while the idea of counterfactuals were discussed at length I walked away from the conversation feeling that the whole thing sounded kind of dumb. But I don't think it was idea of Constructor Theory itself, but instead how the participants danced around the topic, delving into philosophy debates instead of explaining existing ideas behind it. Like they were discussing the meta of Chess without ever explaining what the game even was. But here in just 8 minutes I was able to go, "Oh that's what they meant!"

Constructor Theory reminds me of fractal math, and especially the way the Mandelbrot set is built. You test a number through an equation and if it blows up toward infinity, it's out. If it stays within certain bounds, it's in.

I like a lot that part at around 13 minute mark. Showing us how the world works very differently from what we intuitively expect, what we expect by using what some would call common sense. I feel lucky to live in the age where I can hear the answers to these questions, as opposed to the age of ancient Greece, where philosophers had to make guesses and essentially make stuff up. These philosophers never stood a chance of predicting how reality actually works, because it is so different from what we experience on our scales. This is a great channel which answers the questions which we all head as kids, and which all people asked themselves during thousands of years (if not way more than that). Even without the theory of quantum mechanics and gravity, and without knowing why mass pressure etc. cause gravity, or whether time and space are emerging properties or not, just presenting things that we know is so fascinating to hear. I am actually excited about the fact that on the smallest scale universe doesn't work the way we would imagine. It only makes it more interesting.

This sounds reminiscent of Gödel's incompleteness theorem. He was able to abstract away the mathematical operations and describe any possible equation as a binary choice between it being true or false, much like how the counterfactuals are either possible or impossible and allow you to ignore the specific equations themselves.

@dojoguitare 2 роки тому

Constructor theory seems to parallel David Hilbert's efforts to formalize all of mathematics before Kurt Gödel showed that such a task was impossible.

@marzadam3721 2 роки тому

It is always interesting that with every new methodology, we continuously think that now we've got, and thereby can explain everything.

@markmcd2780 2 роки тому

OK, so only part way through but seems to me, there's a possible 'bump' in the constructor road. Who or what decides what tasks are 'possible' and what constructor is needed to make them happen?

@NestorKYAT 2 роки тому

Isn't this more of an epistemological framework than a theory? Not that there's anything wrong with that. I think everything would be better if physicists and philosophers of science collaborated more or if more physicists were more philosophically inclined (like Sean Carroll, for instance)
