Is it time to quantize time? Everything is quantum in quantum mechanics... almost. Time remains a mysterious flowing quantity slotted in to the equations. Surprisingly, there's a model for making time quantum, with a radical consequence: the overall universe is timeless. How is it possible to experience a flow...

JOE ROGAN: DO QUANTUM COMPUTERS PROVE THE MULTIVERSE EXISTS? "There's an equation that quantum computers solve quickly, like in a couple of minutes, that if you converted the entire universe into a computer, it would take so much time to solve this equation that the universe would die of heat death. And these quantum computers can solve it in minutes. They believe this is proof of the multiverse, that this quantum computer is somehow connected to other sources of computing power in an infinite number of universes." Source: Joe Rogan Experience

Why quantum theory could have a fractal structure: explained in 83 minutes. The notion of true quantum nonlocality is absurd. In the latest episode of the Quantum Foundations Podcast, Prof Tim Palmer from the University of Oxford suggests that there is a hidden assumption in standard quantum mechanics, and dropping it will save us from this absurdity. Namely, the reality of counterfactuals: the physics of what could have happened but did not. Inspired by chaos theory and the fractal structure widespread in atmospheric physics, Palmer has developed a new underlying structure for quantum theory, with radical implications for our fundamental principles of quantum physics; the limits of quantum computation; and perhaps even the search for quantum gravity. Watch on my YouTube channel, or listen on Spotify and Apple Podcasts!

⚡ QUANTUM REALITY JUST BROKE TIME ITSELF ⚡ Scientists have uncovered something unimaginable: a way to measure time without clocks, without ticking, without a starting point. Just pure quantum patterns… electrons dancing inside super-charged atoms… creating “fingerprints” that reveal exactly where in time you are. No beginning. No end. Just a map of the universe hidden in quantum waves. This changes EVERYTHING — from quantum healing… to energy work… to how we understand reality itself. JOIN TO LEARN MORE 👇👇👇

BITCOIN RAILS EPISODE #18: MAKE BITCOIN QUANTUM RESISTANT | with BIP360 author Hunter Beast Hunter Beast 🕯️ Quantum computing is a complicated topic—one that incites equal amounts of fear and skepticism depending on who you talk to… especially in Bitcoin. In this episode, BIP360 author Hunter Beast wisely shares why the “truth is likely somewhere in the middle,” citing incremental advancements in quantum computing that may eventually pose a legitimate threat to some Bitcoin addresses—as well as steps we can take to protect ourselves in the short, medium and long term. The correct posture is to “be prepared, not scared,” says Hunter Beast 🕯️ Ultimately, the introduction of quantum resistant cryptography—via proposals like BIP360—will be needed for higher degrees of security. That said, individuals can mitigate personal risk substantially through proper address-use hygiene. This episode breaks down the specific challenges Bitcoin will face in the event of a quantum attack, the likelihood of an attack over time, and the steps we’ll need to take at the individual and communal level to ensure Bitcoin’s safety. This episode includes detailed discussion of: 1) How quantum computing could potentially affect Bitcoin public/private key cryptography—and technologies built on vulnerable addresses (e.g. Taproot) 2) Best practices for protecting yourself against quantum in the short and long term 3) Implications of vulnerable address types—e.g. what about Satoshi’s coins? 4) Deep Dive into BIP360 + proposed long-term solutions 5) Industry roadmaps for quantum computing + how banks and governments are preparing for “Q Day” As always, this episode can be viewed on Spotify or YouTuve—full episode in the comments or linktree in my bio. This episode is powered by Best In Slot—the leading API for Ordinals and BRC20 data aggregation and indexing. TIMESTAMPS: 00:00 Intro 02:05 What is quantum computing? 04:30 How could quantum threaten your Bitcoin wallet? 06:50 Addresses that are safe from quantum 09:13 Satoshi’s coins are in danger! 11:25 What happens if Satoshi’s coins are touched? 14:45 Do we softfork to shield Satoshi’s coins? 16:38 “Transitory inflation” for bitcoin after quantum 21:05 Why Taproot addresses are vulnerable 23:50 Do NOT reuse your Bitcoin addresses! 26:03 When will Quantum become a threat? 28:34 The long/short exposure attack; explained 31:45 Protection using private mempools 33:20 Why all the new Bitcoin L2s are in danger 37:45 Quantum is 5 to 10 years away, governments fear 40:34 Non-Bitcoin systems threatened by quantum 42:26 Centralized systems can adapt to quantum 43:50 Hunter’s BIP: Post quantum cryptography in Bitcoin 47:40 Hunter’s three new signature algorithms 53:48 Is new cryptography on Bitcoin risky? 56:33 Why not just stick to hash-based cryptography? 58:49 A 16X discount for quantum resistant addresses? 01:02:30 Creating quantum resistant multisig addresses 01:04:00 What is Frost? 01:06:50 The long process of approving a BIP 01:08:30 What developers think of Hunter’s BIP 01:10:00 Matt Corallo’s concerns with Hunter’s approach 01:11:00 Steps to implementing the BIP 360 01:17:00 Where to learn more about BIP 360 01:17:50 Who can push the button to change Bitcoin?
