History Meets Science

Why Does an Artificial Sun Need to Be Hotter Than the Sun? Earth, a small blue planet. Its story, and that of the whole solar system, goes back to the day the Sun was born. Next to that long history, my own existence and memory are smaller than a speck of dust. And yet in that short memory, the Sun has always come up and sent its light down without fail. They say it will keep that promise for another five billion years or so. Taking that Sun as a model, humanity is running a small experiment of its own. We are building an "artificial sun" in the hope of abundant energy, and bit by bit, the research is paying off. Then a small question crossed my mind: what is the difference between the Sun and an artificial sun? Earth and the Sun seen from deep space, emphasizing the vast scale and age of the solar system The Sun and an artificial sun both run on fusion, yet they work in almost opposite ways. Follow the numbers, from a plasma built to run hotter than the S...

Why Smart People Fall for Scams (And Skeptics Do Too) By James · October 8, 2026 Picture this. It's close to midnight, and a careful person, the kind who reads the fine print for a living, is about to send money they can't afford to lose. Nobody is forcing them. The request came from someone they love, and every step that led here felt reasonable at the time. If a stranger had asked for the same thing, they'd have hung up in ten seconds. So what changed? It's the question under a far more common one: why smart people fall for scams that look obvious to everyone afterward. When that happens, intelligence usually isn't what runs the show. Trust is. So are love, secrecy, urgency, and the plain reluctance to admit a choice was wrong. All of which comes down to this: at what point does a person start trusting someone else's story more than their own judgment? A professional weighing a message from someone they trust One thing up front: I'm not ...

Are We the First Intelligent Life in the Universe? Maybe Not Are we the first intelligent life in the universe? It sounds like a yes-or-no question. But one word in it is stranger than it looks: first . That is a word about time, not distance. Imagine an intelligent species that appeared a billion years ago, lasted a few thousand years, and vanished long before there were humans to notice. If something like that happened, distance would not be what kept us apart. Time would. I didn't start with aliens, though. I started with a quieter question: why do we exist, and how did we come to be? The more I turned it over, the further my mind drifted, until it ended up among the stars. By aliens, I mean intelligent life, someone like us, who lived a life and asked why they were there at all. I do think someone like that has existed somewhere besides here, maybe long before us. I don't have evidence for that. What I have is a problem with the alternative: that in all that t...
