How do flat earthers explain time zones1/11/2024 ![]() ![]() Yes, it can, but only at a certain illumination angle – when it’s perpendicular to the Sun’s rays. Someone might argue that a flat disk can also produce a round shadow. The only shape that makes a perfectly circular shadow every single time, no matter the object’s orientation, is a sphere. Moreover, the Earth’s shadow on the Moon is ALWAYS circular at every lunar eclipse and doesn’t change with the Earth’s rotation. ![]() ![]() If you look at the Earth’s shadow during a lunar eclipse, you’ll notice that it is curved – like a part of a circle. ![]() Can you tell for yourself that the Earth is not flat? Yes, you can, and we’ll tell you how! ContentsĪ lunar eclipse occurs when the Earth comes between the Sun and the Moon, casting a shadow over our natural satellite. Although the very existence of the “flat-Earth theory” is quite discouraging, we’d like to use it in a positive way – as an exercise in critical thinking. While some people are getting ready to send astronauts to Mars in just a few years, other people, apparently, still don’t believe the Earth is round. If it were complete, this ammonite's total diameter could have been from 2.5-3.5 metres.We live in strange times. The largest specimen found is 1.8 metres in diameter but is also incomplete. The largest known species of ammonite is Parapuzosia seppenradensis from the Late Cretaceous. Zoë says, 'Ammonites were quite diverse and evolved rapidly, so if you sample stratigraphically through rocks, you can actually see the evolution and the changes through them.' How big were ammonites?Īmmonites came in a range of sizes, from just a few millimetres to times bigger, with larger sizes more common from the Late Jurassic onwards. However, it is estimated that over 10,000 species of ammonite - possibly even over 20,000- have been discovered. But when ammonite fossils that looked unique were found in the past, they tended to be recorded as new species instead of as the microconch (male) or macroconch (female) of an existing species, as this difference between the sexes was not yet known about. Like modern cephalopods, ammonites displayed sexual dimorphism, which is the noticeable difference in appearance between sexes. But figuring out exactly how many species have been found so far is a bit tricky. ![]()
