Could Quark Stars be the Engines of Self-Replicating Strange Matter?

Between you guys, PBS Space Time, and SEA, there's arguably enough ridiculously high quality & comprehendible content available on astrophysics that it makes these kinds of cutting edge developments within the field relatively accessible to those of us who enjoy learning about it but aren't academics. Thank you for qll that you and your team do, we truly appreciate your time and dedication to communicating the science! 🙏

I have beeb worried for your well-being for rare inactivity on YouTube, Sir. You are the true mentor for me since you carefully choose every exact word in laymen's terms in each and every of your contents. I always rewatch your video about time-travelling whenever I am too down or sad with the losses uncontrollable, and emphasise the core message you gave in that one. I really hope to meet you in person to be able to tell you how your YouTube videos deeply affect on one's life and thank you. Take care, Sir.

Watching and learning from these videos has taught me to be observant about things in the universe. Like when Dr. Kipping goes from wearing a T-shirt while on-screen speaking into the mic. To completing the sentence on-screen speaking into the mic, now with jacket on. This guy is a God.

This channel is a must-go for every astronomy friend. Not as bombastic as some TV documentaries, yet still understandable even for us, amatures and enthusiasts.

Man, few creators match the awe and vibe from your videos, excellent work as always!

As an aspiring Astrophysicist, I really enjoy these videos! Neutron Stars are so interesting not only due to their characteristics, but because a select few are very close to that 3 SM boundary. Studying those few could help refine existing boundary estimates, and give a greater understanding on the limits of matter at those insane pressures. Which is super exciting.

Dr. Kipping, you are seriously the best astronomy and physics journalist I have ever come across (and I consume a lot of that content.) Thank you for being the adult in the room about strangelets/strange matter, for the truly curious, the truth is always more interesting than any fiction. Plus, I can pencil cross off the existential dread of the strangelet apocalypse. Every video you release makes my world just a little cooler, thanks!

Just 2 minutes in and this is incredible!! I just love your style in narrating these amazingly crafted videos! You have a real talent for explaining such complex topics in great detail and the effort you put into making these vids really pays off😄👍 these bizarre cosmic objects are explained so well by you which makes it so much easier to comprehend how this universe works (not an easy task!😂), Love this content, please keep it up as its greatly appreciated!!! ❤😊 Man this universe is so unbelievablely strange.

I like that you give credits for clips and even link YouTube channels for clips in the video. It is a good example that others on YouTube should follow.

David, every time i see one of your videos it makes me smile because I know i learned something new. Thanks for all of your hard work <3

Ahhh, only a Cool Worlds upload can brighten my day this much.

Love all the videos you post! All of them are so fascinating. Keep up the good work.

It's a great day! Thanks David.

I have always found neutron stars more fascinating than black holes because we actually kind of know what is going on inside them. And they do not disappoint. Definitely my favorite objects in space. I just wish we had was a really clear picture of one in multiple wavelengths so we could see the surface.

It’s just nice when instead of destroying the universe, astrophysics ends up making us feel a little more safe and secure in a cosmos that doesn’t like us. Thanks for another amazing episode.

Thanks so much David. The podcasts are fascinating too! Nothing else quite like this channel, the level of detail and depth is perfect for curious adults with an existing interest in astronomy and astrophysics. Thanks for spreading the knowledge.

David, I know you are busy with work as well but if I could be selfish for just second here I wish you would post content more frequently 🙏 ….. I absolutely, thoroughly enjoy your videos! It has reignited my love for all things astronomy ❤ Thank you so very much for this!!! Edit: Grammar error 😉

David your channel is my absolute favorite on the YouTube platform. Please keep up the great work!

Wonder stuff to listen to while driving to work. Keep up the great work.

Nothing brings my mind back to peace like Professor Kipping's narration of wonder.
