Summary
Marketers are increasingly critiquing the practice of "bull spend," where advertising budgets are allocated to metrics that may appear impressive but do not yield tangible results. This phenomenon is highlighted in discussions about the disconnect between marketing dashboards and actual business outcomes, particularly when scrutinized by finance departments.
The episode also delves into the fascinating world of black holes, exploring their formation and significance in astrophysics. Black holes are formed when massive stars undergo gravitational collapse, leading to a singularity where density becomes infinite. The discussion emphasizes the interplay between general relativity and quantum mechanics in understanding black holes, particularly how they challenge existing theories of physics.
Listeners learn about the lifecycle of a black hole, from the initial stages of a massive star's death to the eventual creation of a black hole that alters the fabric of spacetime. The episode touches on the implications of black holes for our understanding of the universe, including the potential existence of primordial black holes formed shortly after the Big Bang, and the ongoing search for evidence of these elusive entities.
Overall, the episode combines marketing insights with deep scientific exploration, illustrating the complexities of both fields and their impact on our understanding of reality.
Show Notes
Black holes are not just the strangest objects in the universe, they're the sharpest test we have of how reality actually works. This episode explores how these extreme cosmic laboratories force general relativity and quantum physics into direct confrontation. We look back through a decade of content to understand their formation and the theoretical diagrams that describe them, offering a journey through the profound implications of these celestial objects for our understanding of space time and astrophysics.

As far as the north magnetic pole, where the needle starts spinning wildly? Compass needles align with magnetic field lines, and on the precise spot of magnetic north, those field lines are vertical. So just tilt your compass 90 degrees and you can continue your journey - either down to the molten iron dynamo surrounding the Earth’s core, or up. But up to where? The answer - to everywhere - and today, that’s where we’re going to go.Sign up for the mailing list to get episode notifications and hear special announcements!https://mailchi.mp/1a6eb8f2717d/spacetimeHosted by Matt O'DowdWritten by Matt O'Dowd Graphics by Leonardo Scholzer, Yago Ballarini, and Pedro OsinskiDirected by Andrew KornhaberAssistant Producer: Setare GholipourExecutive Producers: Eric Brown and Andrew KornhaberEnd Credits Music by J.R.S.

I mean it might be – I’m just not saying it. And perhaps it doesn’t make any difference. Even if this is the prime, the original physical universe, rather than somewhere deep in a simulation nest, we can STILL think of our universe’s underlying mechanics as computation. Imagine a universe in which the most elementary components are stripped of all properties besides some binary notion of existence or non-existence. Like, if the tiniest chunks of spacetime, or chunks of quantum fields, or elements in the abstract space of quantum-mechanical states can either be full or empty. These elements interact with their neighbors by a simple set of rules, leading to oscillations, elementary particles, atoms, and ultimately to all of the emergent laws of physics, physical structure, and ultimately the universe.Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangJustin LloydAnton LifshitsCoolAsCatsDavid NicklasFabrice EapQuasarDean FuquaMark RosenthalMayank M.

Assume perfect coordination and the ability to localize my palms to the quantum level. 15 halvings gets them to within a cell’s width. 33 to within a single atom, 50 and they’re a proton’s width apart. Half the distance 115 times and they’re a single Planck-length apart - 1.6x10^-35 meters. Surely we can keep going - .8, .4, .2 x10^-35 m? Bizarrely, those distances might not even exist in any meaningful way.
