Every theory is an approximation: why good physicists admit ignorance
Andrew Strominger says every theory has edges, Michelle Thaller insists scientists must admit what they do not know, Carlo Rovelli praises humility, and Brian Cox and Lisa Randall describe the limits of science. Their shared stance is a useful guide to how much trust any scientific claim has earned.
Which quantum mechanics is right? Many worlds, relational reality and Penrose's gap
Sean Carroll defends many worlds, Carlo Rovelli says particles exist only in interactions, Roger Penrose argues gravity points to something missing in the theory, and Lisa Randall asks whether electrons exist when no one is looking. The disagreement shows that the equations are settled while their meaning is not.
Your head ages faster than your feet: relativity's time made intuitive
Carlo Rovelli, Michelle Thaller, Bernardo Huberman and Sean Carroll each explain how speed and gravity change the rate at which time passes. Their different pictures make one of physics' strangest tested facts easier to grasp.
Did the universe have a beginning? Big Bang, inflation and endless cycles
Brian Cox asks whether the universe began at all, Roger Penrose proposes eons that cycle forever, Brian Keating recounts the hunt for evidence of inflation, and Michelle Thaller explains what the cosmic afterglow shows. Their accounts mark the line between what cosmology has measured and what it still only proposes.
Moon landing doubts and flat Earth: how science answers public distrust
Joe Rogan and Matt Walsh debate the moon landing, Brian Cox talks about social media and flat Earth, and Ann Druyan explains the role of science in a democratic society. Their exchanges show why distrust spreads and what kind of explanation scientists think can win people back.
Why conversations about the cosmos keep turning to artificial intelligence
Nathalie Cabrol links AI to what she calls humanity's teenage years, Michelle Thaller considers AI, meaning and life after work, Brian Cox asks whether a godlike intelligence would want anything, and David Kipping connects AI to the simulation argument. Scientists who study the universe keep arriving at the same question about our own future, and their long view is a useful frame for it.
Made of stars: how the universe forged the elements in your body
Michelle Thaller explains why we are made of stars, Anna Frebel traces heavy elements to the first stars and neutron star mergers, and Harry Cliff asks why matter survived at all. Their accounts connect everyday atoms to events billions of years old, one of the clearest ways to grasp our place in the cosmos.
Follow curiosity, switch fields: how physicists say discoveries happen
Bernardo Huberman recommends changing fields to find uncrowded beaches, Neil Gershenfeld describes discovery as ready, fire, aim, and Andrew Strominger credits thought experiments and a willingness to be wrong. The shared lesson is that breakthroughs come from play and movement more than from a fixed plan.
Godel's shadow: what mathematics says computation can never do
Roger Penrose builds on Godel and Turing to argue that understanding goes beyond algorithms, Edward Frenkel sees paradox and limits at the heart of mathematics, and Stephen Wolfram describes computational irreducibility. Each identifies a different hard limit on what calculation can predict or prove.
Mathematics as the language of nature: why abstraction keeps working
Roger Penrose marvels at the role of complex numbers, Edward Frenkel links imaginary numbers and the Langlands program to physics, and Andrew Strominger reflects on how physics and mathematics feed each other. Their reflections address why ideas invented on paper keep turning out to describe the world.
Particles are ripples: the field picture behind modern physics
Harry Cliff describes particles as ripples in invisible fields, Don Lincoln explains why empty space is not empty, and Lisa Randall walks through the Standard Model and where it might break. The field view replaces the picture of tiny balls and makes sense of mass, forces and the vacuum.
Remote viewing: what its proponents claim and how they defend it
Jacques Vallee recounts psychic research at SRI and learning remote viewing, and Thomas Campbell describes out-of-body work at Robert Monroe's lab and says he taught AIs to remote view. Presented as claims, their accounts let readers see what evidence is offered and judge how far it falls from accepted science.
Did the universe have a beginning? What physicists know about the earliest moments
Brian Cox asks whether the universe had a beginning, Michelle Thaller explains the cosmic afterglow and the Big Bang, Anna Frebel reads the first billion years in the oldest stars, and Harry Cliff asks why there is matter at all. Each approaches the early universe with different evidence, which shows readers what is measured and what is still open.
How life gets started: hydrothermal vents, panspermia and what counts as living
Nick Lane argues life began as chemistry in hydrothermal vents, Betül Kaçar discusses panspermia and rerunning the tape of life, and Nathalie Cabrol focuses on the nature of life and not just its origin. Their different starting points matter because the definition of life decides where and how we search for it.
The Great Silence: why intelligent life may be rare even if microbes are common
Brian Cox discusses the Great Silence and lonely civilizations, Nick Lane argues complex cells arose only once and the galaxy may be full of bacteria, Betül Kaçar points to life's one-time inventions, and David Kipping and Nathalie Cabrol weigh the Fermi paradox. Together they separate the question of life from the question of intelligence, which changes what we should expect to find.
Software 2.0: when learned models replace hand-written rules
Andrej Karpathy describes Software 2.0 and Tesla's data engine, George Hotz explains comma's learned driving policy, and the DeepSeek analysts describe reinforcement learning's aha moment. Each shows systems improving when engineers stop writing rules and let data and training do the work.
Who pays for the commons? Open source maintainers, burnout and money
VLC's Jean-Baptiste Kempf turned down millions, FFmpeg's maintainers describe burnout under Big Tech demands, Jimmy Wales refused advertising for Wikipedia, Guido van Rossum stepped down as Python's leader and Vitalik Buterin proposes quadratic funding for public goods. Together they show how fragile the volunteer work under the internet is and what might sustain it.
Will answer engines replace search? Four builders on the web's future
Marc Andreessen asks whether AI will replace search, Aravind Srinivas explains why Perplexity builds an answer engine and avoids Google's game, Sam Altman weighs search and ads, and Jimmy Wales considers what language models mean for Wikipedia. Their views show how the way people find information online may change and who stands to lose.
Emacs, Neovim, VS Code or Cursor: what editors programmers choose now
Guido van Rossum compares Emacs, PyCharm and VS Code, ThePrimeagen champions Neovim, the Cursor founders rebuild the editor around AI and George Hotz gives his view of AI coding tools. Their choices show what programmers want from an editor as models start writing more of the code.
How dangerous is AI? Doom skeptics versus the cautious labs
Marc Andreessen calls AI doom a religion, Yann LeCun and George Hotz argue open development is the safer path, while Dario Amodei lays out safety levels and a responsible scaling policy and Sam Altman talks about theatrical risk. Seeing their reasons side by side helps readers judge the risk claims behind AI regulation.
Let users build it: wikis, mods and crowdsourced products that last
Jimmy Wales made contributing to Wikipedia easy and welcoming to newcomers, Todd Howard credits mods for games that last decades, Pieter Levels crowdsources data for his sites, and FFmpeg and VLC run on volunteers. The pattern shows how lowering friction for contributors can outlast a company's own effort.
Small teams, high talent density: how lasting software gets built
Pieter Levels builds alone, George Hotz draws lessons from Twitter's size, Dario Amodei stresses talent density and Aravind Srinivas shares what he took from great founders. They point to the same lesson: a few excellent people who ship fast beat large organizations.
Type hints, ownership and Rust: how much should the compiler check?
Guido van Rossum explains why Python added optional type hints, Chris Lattner builds types and ownership into Mojo, the FFmpeg maintainers debate Rust, and ThePrimeagen compares languages from daily use. The discussion helps programmers decide how much safety to trade for speed of writing.
Why ads worry the people building search, AI and Wikipedia
Jimmy Wales refused advertising to protect Wikipedia's trust, Sam Altman discusses ads and bias in AI answers, and Aravind Srinivas explains why Perplexity will not copy Google's ad-driven model. Their reasoning shows how a product's business model shapes what users are shown.
