What goes up must come down, right? We’ve heard that old saying many times throughout our lives. But as it turns out, gravity isn’t quite so simple.
In this episode of Perspectives, four experts discuss what we know about gravity as well as some of the things we’re still trying to figure out.

I understood the data on gravitational waves better than I understood the multiple unnecessary camera angles and shifts in this video.
-
My dad taught me about gravity when I was 16. He woke me up I was sound sleep and said son, I have to teach you a thing or two about life. I go oh no here it comes, he said no you don't understand. 1. If you fall the ground will catch you. 2. Two gravity never sleeps. 3. Now for the most important part, you never see a dollar bill with his eyes closed so get your butt out of bed and go get a job gravity is up.

Thank you. Really well put together presentation. Much appreciated.
-
This gravity thing is really cool. Sitting on my sofa watching this I was able to leap around the studio so he had to keep turning to look at me. Quantum!
-
Up until recently I’ve become fascinated nerd and learn about the universe and all these educational videos are gold to me.
-
This video is fascinating. How do you get so many different camera angles packed into one video? The scientist talks for about 7 seconds, turns, looks at a new camera, talks for 7 seconds, turns, looks at yet another camera, talks.. and so on over and over and over lol
-
I liked the way you wandered off the topic at the point when talking about a Universal field. Kind of like Goldfish sticking their heads out of the water to have a look around, and promptly fall back into the known darkness of the pond again. 😅
-
Terrific video showcasing the chronology of major physic ideologies. Quantum’s gravitational impact intriguing.
-
8:27 Strictly speaking Einstein says that the energy-momentum and spacetime curvature are correlated in a certain strict way, it does not say that one causes the other.
-
Very well done. Thank you!
-
So glad to find you thank you so much
-
Thanks. It is so informative.
-
if a gravitational wave is so difficult to detect on a planet the size of the earth its no wonder that we cannot see the effects on the molecular level.
-
A week after this video was uploaded, it has 334 comments. I read through all of them, and they're—boy oh boy—not at all what I expected for a science video! Now I'm seriously worried for the future of science. 😱
-
your ability to connect with your audience is phenomenal!
-
Excellent! Thanks.
-
Well done summary of the history of gravity and the current paradigm.
-
Hi, as a retired science teacher, I say this presentation is outstanding. Excellent!!!!!!!
-
This was great.

Sending gratitude from a Daoist monastery near Seattle (US)! 🌲☯️👍🏻
