I had an incredible conversation with @stephen_wolfram a few days ago. Here's the first excerpt. More to follow… 3 hours more! youtu.be/86iQABalqzk

The Last Theory
@lasttheory_
#WolframPhysics might be the most fundamental scientific breakthrough of our time. Follow me for insights into what might be the _last_ theory of physics!

@lasttheory_ @ladidadadum @getjonwithit @wolframphysics Your video with @getjonwithit was wonderful!
English
Much more work is needed before this is really a robust result (paper forthcoming, hopefully by the end of the year), but the initial findings are clear:
Spacetime discreteness may be observationally detectable in things like quasar luminosities. (1/6)
English
@mostidas @getjonwithit Yes, exactly. According to the Wolfram model, space is a discrete hypergraph of nodes and edges, and rules are applied to the hypergraph one after the next, making time, too, discrete.
English
@ladidadadum @getjonwithit Good questions, @ladidadadum
As @KennyEvitt says, yes, this is based on a hypergraph, following rules, as in @wolframphysics
And yes, @getjonwithit has shown that GR can be derived from the hypergraph under simple assumptions: arxiv.org/abs/2004.14810
English
@getjonwithit Very cool!!
Did I understand correctly that your discretized spacetime is a hypergraph, which evolves under graph rewriting rules?
What’s the reference paper for that? Did you show that this approximates GR? In what way exactly?
English
@skdh You should take a look at Sabine's video, Jonathan! @getjonwithit
English
You've been asking me for years to talk about Stephen Wolfram's theory of everything, so here we go at last.

@skdh @d0rc As @skdh notes, she's not criticising the Wolfram model merely for being discrete. Even better, she said later in the video that @stephen_wolfram and @getjonwithit have worked to address the issues with discreteness.
English
@d0rc Not what I said. I said we know the continuous equations to work and we know it's difficult to approximate them in all circumstances with discrete equations and preserve all symmetries. With all due respect, I think you missed the point.
English
This is the most measured assessment of the Wolfram Physics Project I've seen... _and_ it gives proper credit to Jonathan Gorard. Thanks @skdh for this! youtube.com/watch?v=-yzdjz…

@curiouswavefn I wonder how the Russians spin the multiple failures of SpaceX rockets?
The Russians are daring, experimenting, just like SpaceX
If we use every failure as sad, rather than as an inevitable setback on the path to success, we’ll never get anywhere
English
As I read Dostoevsky or Chekhov or study the work of Russian scientists or mathematicians, it seems exceedingly sad to see what has happened to a country which had so many elements of greatness in it.
English
Emblematic of many things Russia these days.

BREAKING 🚨: Russia's first lunar spacecraft in decades has crashed into the moon after a ‘glitch’ sent it spinning out of control
English
@eigenbros Yes, yes, please, please, everyone listen to this!
English
@DrBrianKeating Movies have big budget marketing teams to promote them
Sports have legions of commentators to explain to fans what’s going on
What’s wrong with all these people talking about movies, sports, science or anything else?
English
Why is it that science needs “popularizers”?
Movies don’t
Sports don’t
Social media doesn’t
It’s time we realize actual scientists have an obligation to develop their communication skills.
We’ve been gifted the greatest script imaginable. The only thing holding us back is us.

This is the most important news out of @wolframphysics for a long time:
Jonathan Gorard @getjonwithit is back
Wolfram Physics Project@wolframphysics
The Wolfram Institute gets back into action! Announcing a new phase for the Wolfram Institute. Tune in Friday 16:00 UTC to hear from the new Director of Research @getjonwithit, the new Director of Operations Barbara Mack and research fellows. @wolframinstitute" target="_blank" rel="nofollow noopener">youtube.com/@wolframinstit…

Here’s @getjonwithit’s take:

Jonathan Gorard on causality is always going to be a treat!

You can find the stream recording here: youtube.com/watch?v=oMo38r… It will quickly become obvious that the audio is terrible. If anyone who understands audio/video editing can find a way to make a version with the echo reduced or removed, I will be eternally grateful.

Crucial question for #WolframPhysics
Where are all the particles?
