Five Scientific Theories That Will Blow Your Mind

Thanks for another video my son and I can bond over. He finds many videos, about what he likes, to share with me. I like it when I can reciprocate with videos I find. Keep up the awesome work.

0:35 - Chapter 1 - Quantum entanglement 3:05 - Chapter 2 - The collatz conjecture 6:20 - Chapter 3 - Alien descendance 9:05 - Chapter 4 - False vacuum theory 11:20 - Chapter 5 - The immensity of the universe

I've been obsessed with what the universe is and how it works since I was 13. I live to understand it better and think about it and while I've taken a fondness to this channel after recently discovering it, these space and physics themed videos will always be my very favorite.

In the quiet of the night aboard the USS Enterprise, Commander Riker and Captain Picard found themselves in the captain's ready room, enjoying a rare moment of relaxation. The stars outside the window formed a mesmerizing backdrop, a reminder of the vastness of space they explored together. "Jean-Luc, do you ever tire of this endless journey?" Riker asked, his voice soft, almost reflective. Picard looked up from his book, a slight smile playing on his lips. "There are moments, Will, when the solitude of command can weigh heavily. But then, I think of the crew, of the friendships we've forged, and it all seems worthwhile." Riker nodded, understanding the sentiment all too well. "We've been through so much together. It's those bonds that keep us going, I think." The captain set his book aside and leaned back in his chair. "Indeed. It's not just the exploration of the unknown that drives us, but the connections we make along the way." There was a comfortable silence between them, one that spoke of years of mutual respect and camaraderie. Riker walked over to the replicator and ordered two glasses of Saurian brandy, handing one to Picard. "To friendship," Riker toasted, raising his glass. "To friendship," Picard echoed, clinking his glass against Riker's.

“Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.” ― Douglas Adams, The Hitchhiker's Guide to the Galaxy

Physicist here. Quantum entanglement would make particles change in relation to their entangled partner, but it would not yield useful information. You could see one particle with spin up and then go to the other particle and see the spin down. However, you cannot force the original particle into one state. The ramification of this is that faster than light communication would be impossible. There are things in the universe that go faster than light (like the expansion of the universe, and even entanglement) but it is information that it yields which cannot exceed light speed.

Your animation of the Solar System, in particular the depiction of the Asteroid Belt, brings up another interesting space fact. Despite there being up to 1.9 million asteroids in the belt if you were to stand on one asteroid you would not be able to see its neighbours as they would be too far away to see! It is not the crowded area of asteroids that is popularly conveyed in images and movies. Flying a space ship through it would not be hazardous!

The immensity of space is even more terrifying when you realize that we only see the observable universe. With space-time expanding faster than the speed of light there are stars that we will literally never be able to see because there is literally not enough time in the universe, even if it never ends, for the light from those stars to reach Earth.

For the last one, you didn't even consider that those galaxy estimates are just for the OBSERVABLE universe. Our little pocket of the observable universe may only be 1/1000000 of the entire universe.

Simon you have a wonderful talent in communication. Thank you for making these educational teaching videos. My students actually stop talking and pay attention when you're on the screen 📚

The vastness of space is just incomprehensible. I saw a couple videos talking about it that really did a fantastic job of making me realize I’ll never even be able to come close to comprehending how little I can comprehend the vastness of space. It’s just not on a scale my brain is capable of thinking about it’s so absurdly large. Words don’t exist to explain how gargantuan it is.

There is a theory which states that, if anybody should ever discover just exactly what the Universe is for and why it is here, it will instantly disappear and be replaced with something even more bizarrely inexplicable. There is another theory which states that this has already happened -- Douglas Adams.

If the universe is so big, why won't it fight me?

In the whimsical land of Far Far Away, Shrek and Donkey discovered a connection that transcended friendship. Amidst their adventures, a deeper bond formed, defying societal norms. Their unconventional love story unfolded quietly, a tale of acceptance and understanding. Far from the conventional fairy tales, Shrek and Donkey navigated their feelings in a world that had yet to grasp the diversity of love. In the end, it wasn't the castle or the dragon that defined their happiness, but the genuine connection they found in each other, proving that love knows no boundaries, even in a swampy fairy tale realm.

Anyone interested in quantum entanglement, false vacuum, and other related subjects should also be watching PBS SpaceTIme, which goes into these subjects in detail. Not the detail a student who could actually grasp the mathematics would get, but the host actually understands the subjects and can simplify them for a general intelligent audience.

If Simon talks any faster he’s gonna end up inventing faster than light communication all by himself.

Loved when you said "documentary" lol I watch Ancient Aliens as a purely entertaining show. They take speculative facts and dubious extrapolation to come to doubtful conclusions that support their view. The phrase "ancient alien theorists say yes" has become a drinking game.

Thank you, Simon. Well researched, informative, and interesting. Your entertaining format is both amusing and inspiring. I appreciate learning more about the world and beyond from you and your team. Please keep it coming!👍

If I recall correctly, the conclusion that quantum entanglement can be used to do faster-than-light communication is, unfortunately, incorrect.
