I’ve often wondered what This American Life would have been if it were British. “Each week, we bring you stories of life in Britain. Not extraordinary life. Not even particularly interesting life. Just… life. Grey, tea-soaked, mildly apolog

Yes, I realize not-having initially understood what LOC DNS actually is. As mentioned, this could of course be applied to Hubble.

Relativity isn’t needed because rockets never get anywhere near the speeds or gravitational extremes where Einstein’s equations matter. At rocket speeds, Newtonian mechanics is so accurate the difference is negligible, so why make things ha

Brilliant! This is both clever and educational. I immediately wondered if it would be possible to do something similar for JWST. Unfortunately LOC DNS records top out at ~42 million meters (42,000 km altitude) and JWST is 38x further out (~

You’re correct. Newton wasn’t proposing a mechanism or deeper cause for gravity; he just described its effects. Einstein did add a “why” of sorts, with general relativity, he reframed gravity not as a force but as the curvature of spacetime

Newton’s physics is still taught and used everywhere because it’s simple and accurate enough for 99% of practical situations. Einstein’s relativity isn’t a better explanation, it just extends it to extreme conditions. NASA still uses Newton

Closed-loop systems like on the ISS already reclaim water from humidity, sweat, and urine, and could be scaled up for larger habitats. Air works similarly: CO₂ is scrubbed, oxygen is regenerated from electrolysis, and trace gases are filter

Starship feels like the ultimate engineering gamble, so many moving parts (literally) that getting it right might be as hard as building the habitats it’s meant to launch. On nitrogen, I keep wondering: if in-space manufacturing matured, co

Closest approach will be October 29, 2025. It’s currently passing Jupiter’s orbit. I’m amazed that even at this speed it will take that long to get here. “Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it

Actually no. Gravity is slightly weaker at your head than at your feet (because it’s farther from Earth’s center). According to general relativity, clocks tick faster in weaker gravity. The effect of your head being higher up outweighs the

I made a significant error conflating different levels of the quantum gravity problem. Special relativity and quantum mechanics have indeed been successfully merged since the Dirac equation in 1928, forming quantum field theory that underli

Thank you! Although don’t go back too far, season one is admittedly a bit of a mess, conceptually ok in places but narratively scattered, but like a corporate handbook that's been photocopied too many times. Season two focuses on space

OP here. This is a blog post for a science comedy podcast, so the science is accurate but delivered with about 47% more workplace humour than you'd find in Physical Review Letters. The core premise is based on real, cutting-edge physic
