I actually have many, many more questions and answers so if you want to see them, like this video and let me know in the comments and I will edit them. Thank you for your support! I wouldn't have gotten this far without you.

I live in the UK - the sky isn't blue, it's grey.

1. So funny to see a celebration of 500K followers when you're sitting north of 9M. 2. A short description of the expansion of the universe that brings it all home for me. So many thanks.

Re: The blue sky, you're right, but you also need to take into account human photoreceptors which are quite insensitive to violet (and wholly insensitive to ultraviolet thanks to our lenses), while being very green/yellow sensitive, biasing the long wavelengths even further in our perception. For animals like birds with UV receptors, the sky would look pale indigo, and for insects that lack red receptors, it'd be downright violet. [Source: me, a visual ecologist]

Thanks Derek for all these explanations. Don't stop doing what you are doing. I (along with many of my friends) really appreciate what you are doing.

Here's a movie idea. the year 3042, young Theodore C. Columbus sets off on a journey to prove that the universe is round. When he arrives at his destination, he finds himself on Earth 1550 years earlier due to space-time navigating errors. Now how does he get back home?

Great video! I feel that you are the only science YouTuber that can thoroughly explain science phenomenon, probably because of you Ph.D and also because of the variety in your videos. Keep it up!

Watching this again in 2021 is pretty funny. You have a luscious black mane, you have 20 times less subscribers and you have no idea how successful this channel will become! Keep up the sterling work!
