Remember what the “U” stands for in “UFO”? You see lights flashing in the sky. You’ve never seen anything like this before and don’t understand what it is. You say, “It’s a UFO!” The “U” stands for “unidentified.” But then you say, “I don’t know what it is; it must be aliens from outer space, visiting from another planet.” The issue here is that if you don’t know what something is, your interpretation of it should stop immediately. You don’t then say it must be X or Y or Z. That’s argument from ignorance. It’s common.

Iridium is also the world’s most famous smoking gun. A thin layer of it can be found worldwide at the famous Cretaceous-Paleogene (K-Pg) boundary† in geological strata, dating from sixty-five million years ago. Not so coincidentally, that’s when every land species larger than a carry-on suitcase went extinct, including the legendary dinosaurs. Iridium is rare on Earth’s surface but relatively common in six-mile metallic asteroids, which, upon colliding with Earth, vaporize on impact, scattering their atoms across Earth’s surface. So, whatever might have been your favorite theory for offing the dinosaurs, a killer asteroid the size of Mount Everest from outer space should be at the top of your list.”", "creator": { "@type": "Person", "name": "Neil deGrasse Tyson" }, "url": "https://sms4smile.com/quotes/neil-degrasse-tyson/along-with-osmium-and-platinum-iridium-is-one-of-the-three-heaviest/", "image": { "@type": "ImageObject", "@id": "https://sms4smile.com/quotes/i/167/neil-degrasse-tyson-143_mount-everest_along-with-osmium-and-platinum-iridium-i_2090545.jpg", "contentUrl": "https://sms4smile.com/quotes/i/167/neil-degrasse-tyson-143_mount-everest_along-with-osmium-and-platinum-iridium-i_2090545.jpg", "url": "https://sms4smile.com/quotes/i/167/neil-degrasse-tyson-143_mount-everest_along-with-osmium-and-platinum-iridium-i_2090545.jpg", "width": 1080, "height": 1080, "caption": "“Along with osmium and platinum, iridium is one of the three heaviest (densest) elements on the Table—two…” — Neil deGrasse Tyson", "creditText": "SMS4Smile Quotes", "creator": { "@id": "https://sms4smile.com/quotes/#organization" } } } } ] }, { "@type": "CollectionPage", "@id": "https://sms4smile.com/quotes/about/outer-space/neil-degrasse-tyson/#webpage", "url": "https://sms4smile.com/quotes/about/outer-space/neil-degrasse-tyson/", "name": "Outer space Quotes by Neil deGrasse Tyson", "isPartOf": { "@id": "https://sms4smile.com/quotes/#website" }, "mainEntity": { "@id": "https://sms4smile.com/quotes/about/outer-space/neil-degrasse-tyson/#itemlist" }, "primaryImageOfPage": { "@id": "https://sms4smile.com/quotes/i/b7b/neil-degrasse-tyson-143_asteroids_asteroids-are-craggy-chunks-of-rock-come_874417.png" }, "description": "3 Outer space quotes by Neil deGrasse Tyson.
