    What Mike Rowe doesn't mention is that we have about a billion years on Earth, then it'll be uninhabitable. The Sun gets hotter and hotter every day. We'll either be extinct, or we'll have moved on to another home planet or moon. So 2.5 billion years from now, it won't matter what becomes of the solar system.

    I've been watching and going to bed to this and ancient aliens for 20 plus years. So much that I finally got my wife and kids to watch it. Its very informative and awesome for story telling. I love this I need more of it especially with Mike Rowe narrating.

    This is interesting but regardless of how much I fight my sleep, I die. I’ll finish the video in the next 3 years at my pace.

    I was surprised by how much the location of an asteroid impact could change the outcome. Striking deep water, a mountain range, or a heavily populated area would produce very different consequences. It's a reminder that understanding the details matters just as much as knowing the size of the asteroid. :face-green-smiling::face-green-smiling:

    From the birth of black holes to the possibility of alien life, the universe reminds us that reality is far more extraordinary than fiction. The same cosmic forces that create stars can destroy them, while the elements forged in their hearts become the building blocks of life. In a very real sense, we are made of stardust, living on a tiny world while trying to understand the immense universe that gave us birth. 🌌✨

    That Eddington limit does not explain Ton 618 or Phoenix A. These monsters blow the Eddington limit equation out of the water.

    This video is absolutely amazing and visually stunning! 🌌✨ Science Channel always knows how to turn complex cosmic knowledge into captivating stories. I was especially impressed by the explanation at [<a href="https://www.youtube.com/watch?v=5pJ-8s7fkFY&amp;t=1362">22:42</a>] regarding the mysterious disappearance of planet Fomalhaut b—the visuals and explanation were so compelling! 🔭🪐 The combination of high-quality graphics and sharp scientific analysis is truly inspiring. Thank you for creating such top-tier content! Wishing the channel continued success and looking forward to more great videos! ❤👍

    Absolutely Mike Rowe is definitely one of the best narrators for TV, if I had a choice , if it wasn&apos;t him narrating it would have to be Morgan Freeman😅
