The year one hundred two thousand twenty-three. A giant meteorite the size of Pluto is approaching the Solar System. It flies straight to Earth. But as the meteorite crosses Saturn’s orbit, a swarm of miner probes approaches it. The scan revealed no minerals on the object, so the searches returned with nothing. Meanwhile, the Space Security Center in Alaska military personnel are setting up a laser. The Solar System witnesses a sudden flare and nothing remains of the dwarf-sized meteorite. Now, unless hydrogen miners on Jupiter post videos of another annihilation on social media… This is what the world will look like when humanity finally becomes a Type Two civilization on the Kardashev scale. We’ll have almost infinite energy reserves, the ability to prepare for interstellar flights, or to instantly destroy any threat. But will humanity really be safe? And what can ruin a Type Two civilization?

The exploration of retrocausality challenges classical views of time and causality, suggesting that effects can precede their causes, influencing our understanding of quantum mechanics, consciousness, and free will. Retro causality offers potential resolutions to issues like non-locality in quantum physics by allowing communication between particles to travel backward in time, which could eliminate the need for higher dimensional configuration spaces and reconcile quantum theory with special relativity. Experimental investigations into retro-causality involve analyzing subtle effects, such as heart rate variations, and require careful methodologies to distinguish genuine retrocausal phenomena from experimental artifacts, while theoretical frameworks explore how retrocausality might address paradoxes and be compatible with concepts like time symmetry. Thinkers in physics and philosophy are increasingly considering retrocausality as a potential framework to address foundational issues, including the measurement problem and the reconciliation of quantum mechanics with general relativity, potentially impacting our comprehension of time, causality, and the nature of reality itself. Discussions around retrocausality extend into areas like decision theory, existential risk, and the nature of consciousness, with some researchers exploring goal-oriented approaches and the potential for retrocausality to enhance artificial intelligence and our understanding of human cognition. Some notable scientists involved: • Roger Penrose is noted for his views aligning with retrocausal concepts and his work on the science of consciousness with Stuart Hameroff. • Yakir Aharonov is cited regarding time in quantum mechanics and weak value amplification. • Ruth Kastner is mentioned in the context of retrocausality and the transactional interpretation of quantum mechanics. • Hu Price’s work is at the center of the study of existential risk. • Ken Wharton is a professor of physics and astronomy working on time-symmetric and causally neutral models of physics. • Matthew Leifer is mentioned regarding block universe ontological models and frameworks for theories with retrocausality. • Daniel Rohrlich is mentioned for his work on fundamental aspects of quantum mechanics and his views on retrocausality. • Richard Feynman is mentioned in the context of interaction with the absorber as the mechanism of radiation. • Simon Shnoll is mentioned for his work showing that the assumption of normal distribution is only mathematical, and that in life sciences and also in physics it is false. • David Lucas is mentioned in the context of trapped-ion processing modules.
What if the “magic” of tomorrow is just science we don’t yet understand? In this episode, we explore the wildest speculative technologies—faster-than-light travel, Dyson Spheres, teleportation, wormholes, and more. Could these breakthroughs redefine our future or explain the Fermi Paradox? Find out as we dive into the impossible!

The odds of a ‘city-destroying’ asteroid hitting Earth in less than 10 years have risen.
Asteroid 2024 YR4 was found by NASA’s Asteroid Terrestrial-impact Last Alert System and it’s now at the top of NASA’s Sentry Risk Table and European Space Agency’s NEO (near Earth objects) impact Risk List.
For a full breakdown of the implications of the asteroid, head here.

That statement, now signed by twice as many concerned citizens, warned about the risk of human extinction from AI, which was perhaps a bit of an overreach, because … well, extinction? Come on! That’s just a movie with Arnold Schwarzenegger.
What they should have warned about was jobs — the redundancy and destitution of most of humanity, unless there’s some kind of universal income funded by taxes on robots.
What no-one talks about, as the AI revolution unfolds in stock market hype and scientific gung-ho, is what they’re all really trying to do.
