Numinous https://numinousfacts.com/ History, science, and the natural world — awe, but verified. en-us When an orca grandmother dies, her grandcalves are 4.5x more likely to die within 2 years — even when salmon is plentiful. https://numinousfacts.com/when-an-orca-grandmother-dies-her-grandcalves-are-4-5x/ https://numinousfacts.com/when-an-orca-grandmother-dies-her-grandcalves-are-4-5x/ In Pacific Northwest killer whale families, a grandmother's death makes her grandcalves roughly 4.5 times more likely to die within two years — even in years when salmon runs are strong. Nature Thu, 27 Aug 2026 12:00:00 +0000 The northern lights aren't paint or magic — they're a collision. Particles hurled off the Sun slam into oxygen and nitrogen 60 miles up, and the sky glows where the atoms take the hit. https://numinousfacts.com/the-northern-lights-aren-t-paint-or-magic-they-re/ https://numinousfacts.com/the-northern-lights-aren-t-paint-or-magic-they-re/ The aurora is a collision — solar particles striking oxygen and nitrogen atoms about 60 miles up, and the light is the atoms releasing that energy. Space Thu, 27 Aug 2026 12:00:00 +0000 Antarctica's ice is so heavy it has pressed the bedrock nearly 1 kilometer down into the mantle. Strip the ice away, and the continent would keep rising for 10,000+ years. https://numinousfacts.com/antarctica-s-ice-is-so-heavy-it-has-pressed-the/ https://numinousfacts.com/antarctica-s-ice-is-so-heavy-it-has-pressed-the/ The weight of Antarctica's ice pushes the rock beneath it hundreds of meters into Earth's mantle — and if the ice vanished, the land would keep rising for more than 10,000 years.
