Why Planets Are Round

Published 2024-03-19
We explore why soap bubbles, cold pigeons, planets, and the sun are all round. Learn about asteroid Ceres’ upgrade to dwarf planet and how Saturn got its rings. We also get into disks: why are some object spheres and other are disks?

Do you still believe in flat Earth?

If the Earth was flat, cats would have pushed everything off it by now.

@2:56 that explains my weight gain in the winter months, i am just puffing up to stay warm

“I can’t afford Cold Duck, I’m drinking Cold Pigeon”😂😂😂
-
When you’re so early that there are no angry flat earther’s unpopular comments around

I am an ex flat earther. I would LOVE the chance to talk with you Neil and Chuck. I've learned a lot since leaving the belief system of flat earth and gaining my trust back into science. From Dunning Kruger to Cognitive dissonance, to personal bias and tribalism. We have a LOT to talk about Startalk. Your own flat earth debunk is one of the most viewed videos on the channel. An actual chat on here with somebody that once believed the earth was flat would probably "break the internet" My email is in the description on my channel. Please get in touch 🙏

The opposite of cold pigeon is "cat sunning itself" - stretched out as long as possible to maximize surface area-to-volume ratio.
-
....! In underlying sentences Neil T have spoken about the earth's changes in a smart way for years in my head anyway. Thanks from Sweden!
-
Today is my Friday… I think I’ll go get myself some ‘Cold Pigeon’ to celebrate the weekend 😂 🍾

I'm not fat, it's just the forces in the universe conspiring against me.😎

I am so happy someone finally gave the difference between spherical and round. I've been trying to tell people this for a while now and they always give me that WTF look!
