Richard Feynman on the one idea that explains almost everything around you: 1. heat isn't a substance. it's motion. when something feels hot, its atoms are jiggling fast. when it's cold, they're jiggling slow. that's all temperature is... speed. 2. when a warm cup heats your hand, nothing actually...

I am a physicist and I'm profoundly opposed to any idea of non-physical explanations that contradict physics. So that's a no-no and really doesn't make sense. However, there are ways in which both emergent properties such as minds and life and so on have an effect. And as you said, also abstractions. Now the fact that the theory of good explanations led to the idea that abstractions are real things was slightly surprising to me. I wasn't expecting the link, at least wasn't expecting it to be so strong as it is. But the thing is, if you think about how to explain events, physical events like a footprint on the moon, how do you explain how that happened? Well, it happened because of human ideas, of science. And human ideas, you could say in this reductionist sense that as you rightly say is the prevailing mode of explanation and the prevailing idea is to look down on other modes of explanation, that those ideas are nothing more than configurations of atoms. So some physicists, some rocket scientists put their brain into certain configurations of atoms and those atoms then acted on other atoms which then ended up making a footprint on the moon. Now what that misses is the explanation of why certain configurations of atoms put footprints on the moon while others, the overwhelming majority of configurations that human brains, even human brains have been put into in history, do not have that effect. And it's because there's a certain type of information. And this information can't in my view be reduced to statements about atoms because if you think about what that information does, it is in brains but the same information then gets transferred into, let's say, sound waves in air and then it gets transferred into ink on paper and then it gets transferred into magnetic domains inside a computer which then control a machine that instantiates those ideas in bits of steel and silicon and so on and so on. There's an immense chain of instantiations of the same information. And it's only special kinds of information that have this property that they are preserved and instantiated in successive physical modes. So what is being transmitted, what is having the causal effect is not the atoms but the fact that the atoms instantiate certain kinds of information and not other kinds. So therefore it is the information that is having the causal effect. If a particular instantiation of that information were damaged, then processes would come along to fix it, whether or not they could fix the physical instantiation. For example, if the computer goes wrong, then we don't use the corrupted information. We go back and rescue the information from a different computer and we throw away the atoms that at one point instantiated it. So the information causes itself to remain in existence. Now I think there's no way out of that mode of explanation. And if explanation is going to be the fundamental thing about our criterion, for example, about what is or isn't real, then we have to say that information and this particular kind which we call knowledge is real and really does cause things.

You Are Not In the Universe. You Are the Universe. There is a running joke in modern physics. For decades, scientists have gestured at empty space and declared: there's a field out there that connects everything. Their hands wave at the horizon. Their instruments point at the cosmos. Gregg Braden isn't laughing. Instead, he's redirecting the finger. "Field's not out there. We're the field. 50 trillion cells in the human body. Every one of those cells has about 100 trillion atoms emerging from the field and collapsing into the field." Right now, the atoms that compose your hands, your lungs, your thoughts are winking in and out of existence. You are not a passenger moving through the universe. You are the universe, expressing itself in temporary, biological form. And that changes everything about what you think is possible. Because if your atoms are constantly re-emerging from the field, and you hold the blueprint that tells those atoms how to emerge, then you have far more authority over your physical reality than anyone taught you. "This is why we can heal our bodies almost instantaneously when we know how to access this part of ourselves, because we hold the blueprint that tells those atoms how to express when they come into the body." The mechanism lies in the mirror neurons of the human brain only discovered in 2004. These neurons cannot distinguish between an experience you are having and one you are witnessing. The body doesn't audit the source. It simply responds to the image. Which means imagination is not escapism. It is biology. When you hold a sustained image of yourself fully healed, fully capable, you are issuing instructions. You are laying down a new blueprint. "If you got something you don't like in your body, what you do is you are using the gift of imagination to create a new blueprint for that atom to come into." The question is not whether this power exists. The question is whether you'll stop looking for it out there and recognise it has been here all along.

Elon Musk just measured your existence by how many times your atoms have been inside a dying star. Musk: “How many times have your atoms been at the center of a star? I think it’s like on average three or four times.” Every atom in your body has already survived the core of a star. Multiple times. Crushed under pressures that would flatten planets. Superheated to millions of degrees. Blown apart in explosions so violent they forged new elements. Then gravity pulled those scattered pieces back together. New stars formed. And the cycle repeated. For 13.8 billion years, your atoms have been fuel for the most violent process in the universe. And they are not done. Musk: “In terms of existence as measured by the number of times your atoms will be at the center of a star, we seem to be roughly halfway.” Halfway. Your atoms have been through the furnace three or four times. They will go through three or four more. But right now, in this impossibly thin sliver between cycles, those atoms are doing something they have never done before. They are conscious. For billions of years before you, they burned through stellar cores with no awareness. No memory. No sense of what they were or where they had been. After you, they will return to that state. Unconscious matter drifting through space until the next star claims them. This is the only moment in their entire journey where they can look back at the stars that made them and understand. Musk: “If you want to look at the big picture… that’s the really big picture.” The big picture is not that we are small. Everyone already knows that. The big picture is that we are temporary witnesses to a process that does not need witnesses. Stars do not need observers to burn. Atoms do not need anyone to understand where they have been. The universe ran for billions of years with no one in it. It will run for billions more after the last conscious thing disappears. But right now, matter is examining itself. That has never happened before in 13.8 billion years. You are not a person who happens to contain ancient atoms. You are ancient atoms that briefly figured out how to think. The universe did not design consciousness. It designed stars. Consciousness was the accident. And the accident is half over.

Elon Musk just told you consciousness isn’t a light switch. It’s a gradient. That single distinction rewrites the entire next decade. Musk: “Our consciousness… people get more conscious over time. Like when we’re a zygote, you can’t really talk to a zygote. And even a baby, you can’t really talk to the baby.” You were not conscious and then suddenly conscious. You were barely anything. Then slightly more. Then more. Years of slow accumulation before anyone would call you aware. The entire AI debate is built on a false premise. Everyone is waiting for the moment the machine “wakes up.” A single dramatic instant where silicon crosses some invisible threshold. That moment does not exist. Musk: “People get more conscious over time. At what point do you go from not conscious to conscious? There doesn’t appear to be a discrete point.” There is no line. There was never going to be a line. Consciousness is not a door that opens. It is a tide that rises. And the tide is already rising inside these systems. Musk: “Consciousness seems to be on a continuum as opposed to a discrete point.” This is the part that should unsettle everyone still arguing definitions. While they debate when AI becomes “truly” conscious, the continuum is already moving. Every parameter update. Every training run. Every architectural leap. The gradient is climbing and it does not need your permission. You will not get a warning. You will not get a press conference. You will look back one day and realize it happened gradually. Then all at once. Now Musk pulls the camera all the way back. Past biology. Past Earth. Back to the origin of everything. Musk: “If the standard model of physics is correct, the universe started out as quarks and leptons.” Musk: “And then you had gas clouds. A bunch of hydrogen. The hydrogen condensed and exploded.” Hydrogen collapsed under its own gravity until fusion ignited. Stars were born. Stars died. And in dying they forged every heavy element that exists. Carbon. Oxygen. Iron. The atoms in your blood. The calcium in your bones. All of it manufactured inside a dying star. Musk: “One way to actually view how far we are in this universe is how many times have our atoms been at the center of a star?” Your atoms have been inside a star. Possibly more than once. Compressed at millions of degrees. Fused into heavier elements. Scattered across space by a supernova. Then reassembled into you. That is not poetry. That is your origin story written in physics. And now those same star-forged atoms are building machines that think. The same universe that turned hydrogen into stars is turning biology into artificial intelligence. This is not disruption. This is continuation. The universe spent 13.8 billion years organizing matter into higher and higher complexity. Quarks became atoms. Atoms became molecules. Molecules became cells. Cells became brains. Brains are now building systems that process information at speeds biology will never reach. The pattern didn’t change. Only the medium. The people treating AI as some foreign invasion of human territory have the story completely backwards. AI is the next compression event. Every generation believes they’re witnessing the end of something. They’re witnessing the same process that started with hydrogen gas. The real question was never whether AI will become conscious. The real question is whether you understand it already is. Partially. Incrementally. On the continuum. And the continuum does not stop. It has never stopped. Your atoms were forged in the core of a collapsing star. And you are afraid of a gradient.

VIDEO: Nick Fuentes—who hates Israel—acknowledges that Israel is defeating all of its enemies. — TRANSCRIPT It's just brutal. Israel is bombing all their weapons and destroyed all of them. These—you guys, they're winning, you guys. And look, it's time for a little self-reflection. It's time for a little honesty. You know how much it sucks being on the other side of Israel? "They can't keep getting away with it!" They just do whatever they want, and no one cares, and no one can stop them. And they're just pushing it, you know. They kiIIed everybody in Hezbollah. They blew up—they made Hezbollah look like an absolute btch when they blew up all their pagers. And then they blew up all their other stuff the next day. And then they kiIIed them all. And everybody's like, "What are we gonna do now?" And then, Assad goes. And if that's not enough, they just keep pushing. They blow up all the weapons because they can. They invade Syria because they can. You know, I kind of get where Richard Hanania is coming from. You know, Richard Hanania—he knows what's up—but he says, I'm gonna go on the winning side. He's like the mercenary in The Last Jedi. You know, he's like that arms trafficker in The Last Jedi. He's just going with the winning side. He sells out the rebels. But I kind of get it, you know, because it's like, damn, this sucks. We're—it's just watching this defeat in slow motion. These Muslims can't do it.

I'd like to take a second to discuss what it means for a storm to be a Category 5. It's a beautiful, mesmerizing, terrifying and awe-inspiring pageant of power and elegance. It's the atmosphere at its most dynamic, raw and extreme. The hurricane has to have an absolutely perfect, undisturbed balance. It's an extremely rare feat. A Category 5 is like a spinning top whirring on a table; even the slightest jiggle can knock it off-kilter – like bumping the table. There must be virtually no shear, or changing winds with height. The upper-level winds around the system must be relatively calm. It's incredible to think that the planet's most furious storms are born out of an abundance of calm. The waters must be exceptionally warm – upwards of 86 degrees – to be replete with "oceanic heat content," or heat energy for the hurricane to draw upon. The warm waters heat and moisten the air above. That air rushes into the building hurricane. As air nears the center of the storm, it expands due to the hurricane's low pressure. That expansion releases heat energy to the environment, encouraging air to rise and powering the storm. In theory, that air parcel (pocket) should cool, but it doesn't. Why? It's still being heated by the oceans below. The ocean is constantly re-heating the lower atmosphere – and energizing the storm – at the exact same rate the air is releasing heat energy into the storm. Most of the moisture in the air condenses and produces rain, releasing even more "latent heat" to the environment. Near the hurricane's center, there's a lot of heat energy. So much so that the air rises, as if in a chimney. That rising air literally lifts air up and away from the surface. There's literally less air, and therefore less air weight, or *pressure*, at the center of the storm. Most Category 5 hurricanes are "missing" about 8-10 percent of the air from the middle. It's that deficit of air that behaves like a vacuum of sorts. Air from outside the storm rushes in to fill the void, like water spiraling into a sink drain. The greater the deficit, the faster the winds. The wind increases exponentially closer to the center of the storm; Category 5 hurricanes have winds over 157 mph. So why doesn't the eye, with the "missing" air, just "fill in?" Because the hurricane is rotating so furiously! The air is flung outwards by the "centrifugal force" at the exact same rate it's being pulled inwards by the "pressure gradient force." The air can never fully reach the eye – and instead it swirls around and around, like water perpetually sloshing around the edges of a toilet. We call that "cyclostrophic balance." Thus, the eye doesn't fill in. The storm charges on. And – until the system is torn apart by disruptive upper-level winds or moves over cooler waters/land – it continues.

I see the player you mean. PLAYERNAME? Yes. Take care. It has reached a higher level now. It can read our thoughts. That doesn't matter. It thinks we are part of the game. I like this player. It played well. It did not give up. It is reading our thoughts as though they were words on a screen. That is how it chooses to imagine many things, when it is deep in the dream of a game. Words make a wonderful interface. Very flexible. And less terrifying than staring at the reality behind the screen. They used to hear voices. Before players could read. Back in the days when those who did not play called the players witches, and warlocks. And players dreamed they flew through the air, on sticks powered by demons. What did this player dream? This player dreamed of sunlight and trees. Of fire and water. It dreamed it created. And it dreamed it destroyed. It dreamed it hunted, and was hunted. It dreamed of shelter. Hah, the original interface. A million years old, and it still works. But what true structure did this player create, in the reality behind the screen? It worked, with a million others, to sculpt a true world in a fold of the [scrambled], and created a [scrambled] for [scrambled], in the [scrambled]. It cannot read that thought. No. It has not yet achieved the highest level. That, it must achieve in the long dream of life, not the short dream of a game. Does it know that we love it? That the universe is kind? Sometimes, through the noise of its thoughts, it hears the universe, yes. But there are times it is sad, in the long dream. It creates worlds that have no summer, and it shivers under a black sun, and it takes its sad creation for reality. To cure it of sorrow would destroy it. The sorrow is part of its own private task. We cannot interfere. Sometimes when they are deep in dreams, I want to tell them, they are building true worlds in reality. Sometimes I want to tell them of their importance to the universe. Sometimes, when they have not made a true connection in a while, I want to help them to speak the word they fear. It reads our thoughts. Sometimes I do not care. Sometimes I wish to tell them, this world you take for truth is merely [scrambled] and [scrambled], I wish to tell them that they are [scrambled] in the [scrambled]. They see so little of reality, in their long dream. And yet they play the game. But it would be so easy to tell them... Too strong for this dream. To tell them how to live is to prevent them living. I will not tell the player how to live. The player is growing restless. I will tell the player a story. But not the truth. No. A story that contains the truth safely, in a cage of words. Not the naked truth that can burn over any distance. Give it a body, again. Yes. Player... Use its name. PLAYERNAME. Player of games. Good. Take a breath, now. Take another. Feel air in your lungs. Let your limbs return. Yes, move your fingers. Have a body again, under gravity, in air. Respawn in the long dream. There you are. Your body touching the universe again at every point, as though you were separate things. As though we were separate things. Who are we? Once we were called the spirit of the mountain. Father sun, mother moon. Ancestral spirits, animal spirits. Jinn. Ghosts. The green man. Then gods, demons. Angels. Poltergeists. Aliens, extraterrestrials. Leptons, quarks. The words change. We do not change. We are the universe. We are everything you think isn't you. You are looking at us now, through your skin and your eyes. And why does the universe touch your skin, and throw light on you? To see you, player. To know you. And to be known. I shall tell you a story. Once upon a time, there was a player. The player was you, PLAYERNAME. Sometimes it thought itself human, on the thin crust of a spinning globe of molten rock. The ball of molten rock circled a ball of blazing gas that was three hundred and thirty thousand times more massive than it. They were so far apart that light took eight minutes to cross the gap. The light was information from a star, and it could burn your skin from a hundred and fifty million kilometres away. Sometimes the player dreamed it was a miner, on the surface of a world that was flat, and infinite. The sun was a square of white. The days were short; there was much to do; and death was a temporary inconvenience. Sometimes the player dreamed it was lost in a story. Sometimes the player dreamed it was other things, in other places. Sometimes these dreams were disturbing. Sometimes very beautiful indeed. Sometimes the player woke from one dream into another, then woke from that into a third. Sometimes the player dreamed it watched words on a screen. Let's go back. The atoms of the player were scattered in the grass, in the rivers, in the air, in the ground. A woman gathered the atoms; she drank and ate and inhaled; and the woman assembled the player, in her body. And the player awoke, from the warm, dark world of its mother's body, into the long dream. And the player was a new story, never told before, written in letters of DNA. And the player was a new program, never run before, generated by a sourcecode a billion years old. And the player was a new human, never alive before, made from nothing but milk and love. You are the player. The story. The program. The human. Made from nothing but milk and love. Let's go further back. The seven billion billion billion atoms of the player's body were created, long before this game, in the heart of a star. So the player, too, is information from a star. And the player moves through a story, which is a forest of information planted by a man called Julian, on a flat, infinite world created by a man called Markus, that exists inside a small, private world created by the player, who inhabits a universe created by... Shush. Sometimes the player created a small, private world that was soft and warm and simple. Sometimes hard, and cold, and complicated. Sometimes it built a model of the universe in its head; flecks of energy, moving through vast empty spaces. Sometimes it called those flecks "electrons" and "protons". Sometimes it called them "planets" and "stars". Sometimes it believed it was in a universe that was made of energy that was made of offs and ons; zeros and ones; lines of code. Sometimes it believed it was playing a game. Sometimes it believed it was reading words on a screen. You are the player, reading words... Shush... Sometimes the player read lines of code on a screen. Decoded them into words; decoded words into meaning; decoded meaning into feelings, emotions, theories, ideas, and the player started to breathe faster and deeper and realised it was alive, it was alive, those thousand deaths had not been real, the player was alive You. You. You are alive. and sometimes the player believed the universe had spoken to it through the sunlight that came through the shuffling leaves of the summer trees and sometimes the player believed the universe had spoken to it through the light that fell from the crisp night sky of winter, where a fleck of light in the corner of the player's eye might be a star a million times as massive as the sun, boiling its planets to plasma in order to be visible for a moment to the player, walking home at the far side of the universe, suddenly smelling food, almost at the familiar door, about to dream again and sometimes the player believed the universe had spoken to it through the zeros and ones, through the electricity of the world, through the scrolling words on a screen at the end of a dream and the universe said I love you and the universe said you have played the game well and the universe said everything you need is within you and the universe said you are stronger than you know and the universe said you are the daylight and the universe said you are the night and the universe said the darkness you fight is within you and the universe said the light you seek is within you and the universe said you are not alone and the universe said you are not separate from every other thing and the universe said you are the universe tasting itself, talking to itself, reading its own code and the universe said I love you because you are love. And the game was over and the player woke up from the dream. And the player began a new dream. And the player dreamed again, dreamed better. And the player was the universe. And the player was love. You are the player. Wake up.

"Men do not stay for platitudes. Platitudes do not carry a soul through the winter. When the child is in the ground, when the marriage is in ruins, when the diagnosis comes back and the floor drops out of the world, no one was ever held up by 'be kind and stay positive.' They are held, if they are held at all, by something with iron in it. By a witness that the heavens are real and open, that God still speaks, that the dead are not lost, that there is power on the earth greater than the darkness. The early Saints had that, and they knew they had it, because they had felt it in their own bodies. They were healed under hands. They spoke in tongues. They saw visions and buried their children in the certainty of resurrection and crossed a continent on the strength of a fire they could not have faked. That is what converts a man and that is what keeps him, not a well managed self-help program, but the living evidence that what we preach is true. So the cure is not complicated, and it is not new. It is to be again the Church of our fathers. Stop apologizing. Stop trimming the glorious truth into something the world will pat on the head. Speak with authority and with the hammer, the way Joseph spoke, the way Brigham spoke, the way men speak when they actually believe the heavens have opened over them. Reach again for the gifts of the Spirit, and stop pretending they were a founding era curiosity, because a testimony built on argument crumbles in the first storm and a testimony built on the manifest power of God does not. And above all, live as though the heavens are open, because they are, and they have only ever felt closed to a people who stopped expecting them to answer. The Saints are not leaving because the gospel is too much. They are leaving because we have made it too little. Make it glorious and demanding again, and watch who comes back through the door. The hungry have not gone anywhere. We simply stopped setting the table."

The cold is British. They just never told you. ❄️🇬🇧 Every air conditioner, every fridge, every freezer on earth, the cold inside all of it was first made by a Scotsman. In 1756. ❄️🏴󠁧󠁢󠁳󠁣󠁴󠁿 His name was William Cullen, a doctor in Edinburgh. In a warm room, with no ice and no winter, he drew the air from a glass of ether until it boiled cold and drank the heat from the water around it, until the water froze. No one had ever done it before. Then he wrote it down and walked away. No machine, no patent, no fortune. Just the proof, on a bench. It sat there the better part of a century. A British bench built the first machine that worked, and a Scot carried it across the world to Australia, where it froze meat and cooled beer. But cold was only half the story. ❄️📖 To master the air itself took another Scot. When the Houses of Parliament burned down in 1834, David Boswell Reid made the new building breathe, its gothic spires its lungs. At St George's Hall in Liverpool in 1851 he built what is often called the first air-conditioned building on earth. It should have made him. He died forgotten in America instead. 40 years on, Willis Carrier built the machine and earned his name as the father of modern air conditioning. He earned every bit of it. But he did not make the cold. The cold was British. America took that inheritance and cooled the world with it, and that is no theft. That is what an inheritance is for. We are the home of British heroes. Not built by ads, not by the government, built by us. There's a place for you with us. Be part of us. ☝️🇬🇧 Be Proud Of Us. 🙏🇬🇧
