The Last Theory

The Last Theory is an easy-to-follow exploration of what might be the last theory of physics. In 2020, Stephen Wolfram launched the Wolfram Physics Project to find the elusive fundamental theory that explains everything. On The Last Theory podcast, I investigate the implications of Wolfram's ideas and dig into the details of how his universe works. Join me for fresh insights into Wolfram Physics every other week.

The Last Theory is a science podcast hosted by Mark Jeffery, with 84 episodes on record and a Required Pod Score of 80. PitchCentric scores this show on Booking Probability, Listen Score, and live audience signals refreshed every 24 hours.

  Stephen Wolfram's 10 ways to have big ideas

  May 28, 202612 minS0

  <p>Stephen Wolfram is an extraordinary thinker.</p><p>He doesn’t seem to think like other scientists. He doesn’t seem to think like other technologists. And he certainly doesn’t think like an academic.</p><p>So I asked him how he thinks. How does he have all the ideas I’ve been exploring at The Last Theory?</p><p>Here are 10 ways to have big ideas, derived from Stephen’s answer:</p>Drill down to the foundationsExperiment with your ideasTry to understand your findingsHave the humility to doubt your expectationsHave the confidence to push ahead regardlessExplain your ideas to o...

  Why are we in the universe we're in?

  Apr 30, 202617 minS0

  <p>If physics is computational, then what gets computed when?</p><p>This is a surprisingly deep question.</p><p>The seemingly even computation of the universe gives us a clue, not just to the nature of time, but to the nature of the universe.</p><p>And it leads us to a wider question:</p><p>Why are we in the universe we’re in?</p><p>Let me introduce you to three different answers to that question... sodifferent that they don’t even agree on whether one universe exists, or every possible universe exists.</p><p>—</p><p>Refere...

  Wolfram on philosophy

  Mar 22, 20267 minS0

  <p>Stephen Wolfram has many philosophical ideas, but I’ve not heard him talk about pure philosophy.</p><p>When I asked him about the relationship between physics and philosophy, I understood why.</p><p>Stephen revealed that he’s much more at home in the concrete world of computer experiments than in the arguments of the philosophers.</p><p>“When I look at the arguments,” he says, “I can’t tell if they make sense or not. There’s too much wiggling...”</p><p>—</p><p><br>Stephen Wolfram</p>Stephen WolframThe Wolfram Physics ProjectWolfram InstituteWolfram Institute Community Discord<p>People and conce...

  How different observers think differently with Stephen Wolfram

  Mar 5, 202610 minS0

  <p>Do different observers think differently? Or does the principle of computational equivalence mean that all observers think the same way?</p><p>Stephen Wolfram takes this question and runs with it.</p><p>If we had brains the size of planets, he suggests, the finite speed of light would force us to think of space and time differently, and abandon the fiction of an instantaneous state of space.</p><p>If we had brains the size of molecules, he says, we’d no longer think of the motion of molecules as random, and we’d find the heat death of t...

  What is time in Wolfram Physics?

  Feb 5, 202618 minS0

  <p>Physics, the way we’ve thought about it for the last few hundred years, requires us to make assumptions about time.</p><p>In our old way of thinking, just as we must assume three axes of space – scales along which we can measure what’s where – so we must assume an axis of time – a scale along which we can measure what happens when.</p><p>It doesn’t matter whether, like Newton, we assume an absolute scale along which we can measure what happens when according to a giant clock in the sky, or whether, like Einstein, we assume a...
