Why Black Holes Break The Universe

Thanks to Storyblocks for sponsoring this video! Download unlimited stock media at one set price with Storyblocks: storyblocks.com/CoolWorlds Let me know your thoughts on this one - what do you think will yield: unitarity, equivalence or locality? Do you have a specific solution you favour?

Please don't break the universe, it's where I keep all my stuff.

My older brother is a physics professor. When we were growing up, he used to let me look through his telescope (the first time I ever saw Saturn was mind blowing!) while he would explain things about space and the universe using language and concepts that even my brain, with its woefully pitiful lack of mathematical understanding, could comprehend. Long story short, I love these videos because they remind me so much of those nights during my childhood looking up at the sky with wonder while someone explains the universe to me. Thank you for that.

fun fact: in german, "Schwarzschild" actually means "black shield", so the Schwarzschild radius translates literally to "black shield radius", which seems somehow very appropriate.

Nothing is broken, our math describing what we see as reality is just incomplete. A deeper understanding will come in time. If you think about it, a black hole is the perfect place for our current models to expose their flaws, pointing the way to new knowledge. Its analogous to how Mercury's orbit helped point us towards GR from classical Newtonian physics.

Ah, a physics video about my bank account

Black holes are where all the missing socks are

I always imagined blackholes as some type of logical glitch in the universe that "crashes" a part of reality like how a game would crash

Maybe this is the answer to the Fermi Paradox. The best minds of every civilization waste so much time pondering blackhole conundrums they never get round to deflecting the asteroid.

That clip of Picard at 11:45 had me in tears! Thanks for the best laugh of 2024!

I love how much science can be built on top of math involving mass, without us having the slightest idea what mass is. Amazing to me.

The way I had black holes explained to me as a child by a physics professor was to imagine a neutron star was reduced in radius to 1/6, to as little as 1/10th of its current diameter. He said that’s where he believes a round black mass (not a hole) resides. He also explained that light can not escape it because light can not exist inside of a black mass (hole), due to the extreme gravitational forces that quite literal rip apart what created the light. That conversation sparked my curiosity about the universe. This video reminded me of him. Thanks for that.

Using pine cones to describe particle spin....there's a first time for everything!! Your video's break my brain, but they are purely amazing at describing complex concepts. Thank you!!

watching videos like these give me so much motivation to keep going in my PhD. i'm doing neuroscience and although it's not physics, i can definitely relate to that feeling of not knowing how to begin understanding the fundamental properties of what we're studying. the brain can sometimes feel like a black hole and i think that's pretty terrifying, but cool at the same time thanks for the video

"Who knew studying something so dark -" could be so enlightening! "- could reveal so much." oh

The outdoor background is incredible. Wish more YouTubers of your style would try it out. So refreshing ❤

What gets me is we live in a universe with problems like this, things that challenge our very understanding of reality itself.. but we still have people saying the earth is flat and bickering about things like border control. We ain't gonna make it.. are we?

They don't break the universe. We just don't know how it works.

David you talk science and I hear the poetry of reality. You give reality a voice and speak it so eloquently. I'm still riding that high from your recent Cool Worlds Podcast with Lisa which got followed by JMG's Event Horizon interview with Lisa. With these mental delights you are really spoiling us and I'm here for all the courses of this meal of galactic information. Love, love, love what you bring to the table of science presenters. You're a great teacher, your students must be thrilled to get to have you be their professor, I know I am. Disney's Black Hole was a nostalgic and much enjoyed opener. Be well David, grateful for what and how you do these things that you do.

I always love listening to your videos. I can’t fully comprehend all the information, but it is so fascinating
