Telescopul care va schimba astronomia există

A hair on the Moon. Twenty micrometers thick, three hundred and eighty thousand kilometers away — clearly seen from here on Earth. The number is not a figure of speech, it's what comes out of the formula when you put the formula honestly. The only problem is that that telescope would have to be the entire surface of the planet. And yet — there's already an idea, written on seven pages in a physics journal, that shows how it could be built. It took me three days to admit that I had misunderstood it. It's an episode about the optical limits of telescopes and how quantum mechanics is very recently entering practical astronomy. If you like long pieces about real physics, the history of instruments, and the moments when engineers say "it can't be done" — and then someone proves it can be done — this episode will stick with you. ✨ Main ideas from this episode: The resolution of a telescope is not determined by magnification — it's determined by the diameter of the mirror. Marketing sells magnification, physics sells diameter. → https://en.wikipedia.org/wiki/Angular... Today's best combined optical telescope has a base of three hundred and thirty meters. To see exoplanets with surface detail, we need ten thousand kilometers. → https://www.chara.gsu.edu/ The trick used to photograph the black hole in M ​​eighty-seven doesn't work for visible light — the electric field oscillates too quickly to be recorded on a disk. → https://eventhorizontelescope.org/ The solution comes not from engineering, but from quantum physics. We no longer carry light, we carry its state — through quantum teleportation, experimentally demonstrated since nineteen ninety-seven. → https://www.nature.com/articles/37539 If you place telescopes near Jupiter and Saturn, linked by quantum repeaters, the resolution on a planet a hundred light-years away reaches six centimeters. As much as a cell phone. → https://journals.aps.org/prl/abstract... 📌 Specific sources for this episode: — Daniel Gottesman, Thomas Jennewein, Sarah Croke — "Longer-Baseline Telescopes Using Quantum Repeaters", Physical Review Letters, two thousand twelve → https://journals.aps.org/prl/abstract... — Anton Zeilinger et al — quantum teleportation experiment, Innsbruck, one thousand nine hundred ninety-seven → https://www.nature.com/articles/37539 — Micius mission — quantum teleportation between ground and orbit at twelve hundred kilometers altitude, two thousand seventeen → https://www.nature.com/articles/natur... — VLTI Public Archive, European Southern Observatory → https://www.eso.org/sci/facilities/pa... 🔥 More stories about the cosmos ►    • Playlist pentru adormit   ⚠️ The product links above are affiliate links.
