At the bottom, almost 11 km down, that's over 1,000 atmospheres, about 8 tons per square inch.https://www.youtube-nocookie.com/embed/00Jvor2GUgU642026-10-09 https://quirkscience.com/films/how-deep-is-the-ocean-really/2026-10-11 https://quirkscience.com/assets/thumbs/UzKL1iX-AXY-og.jpgHow Deep Is the Ocean, Really?The ocean averages about 3.7 km (2.3 miles) deep and reaches almost 11 km at the Challenger Deep. No sunlight gets below about 1,000 m (3,300 ft).https://www.youtube-nocookie.com/embed/UzKL1iX-AXY622026-10-08 https://quirkscience.com/films/we-searched-the-universe-for-a-safer-planet-than-earth/2026-10-11 https://quirkscience.com/assets/thumbs/4Cp20pDwIRA-og.jpgWe Searched the Universe for a Safer Planet Than EarthWe found no safer planet. Earth is the safest place we checked, and its oceans have about a billion years left as the Sun brightens.

Proxima b circles the next star over, 4.2 light years away, and its red dwarf star blasts it with flares.https://www.youtube-nocookie.com/embed/clo8GfOoHsI662026-10-06 https://quirkscience.com/films/why-cant-we-live-on-mars/2026-10-11 https://quirkscience.com/assets/thumbs/JdsKYvxK9zs-og.jpgWhy Can't We Live on Mars?Mars's air pressure is less than 1% of Earth's, so water there boils and freezes at once. How a cooled core cost Mars its air, with NASA sources.https://www.youtube-nocookie.com/embed/JdsKYvxK9zs692026-10-05 https://quirkscience.com/films/what-are-dark-matter-and-dark-energy/2026-10-11 https://quirkscience.com/assets/thumbs/18-WcP5S5FM-og.jpgWhat Are Dark Matter and Dark Energy?Everything ever observed is only about 5% of the universe. The rest is about 27% dark matter and 68% dark energy.

Why each extra nine costs more.https://www.youtube-nocookie.com/embed/G2m6j76X-pM842026-10-01 https://quirkscience.com/films/how-heavy-is-a-neutron-star/2026-10-11 https://quirkscience.com/assets/thumbs/B2d85iQfHLY-og.jpgHow Heavy Is a Neutron Star?One teaspoon of neutron star matter would weigh about a billion tons on Earth.

Why it stays solid, and how the liquid iron around it shields Earth.https://www.youtube-nocookie.com/embed/GlUYqM2-Tkw832026-09-29 https://quirkscience.com/films/how-do-astronauts-come-back-to-earth/2026-10-11 https://quirkscience.com/assets/thumbs/DL5B_fCEUpA-og.jpgHow Do Astronauts Come Back to Earth?A capsule starts home at about 28,000 km/h (17,500 mph). Squashed air, not friction, does most of the heating, and the air does the braking.https://www.youtube-nocookie.com/embed/DL5B_fCEUpA822026-09-28 https://quirkscience.com/films/how-do-rockets-get-to-space/2026-10-11 https://quirkscience.com/assets/thumbs/zsghgm3NPY8-og.jpgHow Do Rockets Get to Space?Rockets throw hot gas down to go up, then go sideways at about 7.8 km/s (17,500 mph) so they fall around Earth and keep missing it.https://www.youtube-nocookie.com/embed/zsghgm3NPY8902026-09-28 https://quirkscience.com/sources/2026-10-11 https://quirkscience.com/privacy/2026-10-11
