  • Everyone in the comment section talking about feeling small: Hey, it's okay. While you may be small in mass, you know what way you're waaaay more than any star? Complexity. You could adequately describe the physics of stellar bodies in less than 40 equations. To describe the complex nature of the interconnected system that is the human brain can (and has) take multiple lifetimes worth of study. You are small, but a single organism is a thousand time more intricate than a star. And humans are (in neural adaption at least) the most complex systems we have yet found. Think of that when you think of how small you really are, you landmark of emergent intelligence, you!

  • Just a quick question, but can we use the energy of the largest star as an energy source to fire a cannon the size of the earth? And how many times can we fire the canon to destroy other planet?

  • If you have access to a VR headset, do yourself a favor and get "Titans of Space" which gives an amazing sense of scale between giants not just in the solar system but of the largest stars in the galaxy. Seriously, the experience of watching Vy Canafis (2000x the diameter of the sun) placed in our solar system is frightening to watch. Would love to see this video redone in VR like that.
