Astrophysicist Janna Levin, PhD, is asked to explain the concept of gravity to 5 different people; a child, a teen, a college student, a grad student, and an expert.
Levin is the Claire Tow Professor of Physics & Astronomy at Barnard College of Columbia University and author of "Black Hole Blues and Other Songs from Outer Space."
She is also the Chair and Director of Sciences at Pioneer Works, where this video was filmed. To learn more, visit pioneerworks.org/

gravity is still a theory

@conanotoole Год назад

How is it a theory?

@hayleygun Год назад

Gravity itself isn't a theory, but we have scientific theories to describe how this fundamental interaction/force works. For example, Einstein's general relativity is a theory of gravity. The theories are tried and tested experiments to explain why and how gravity works. So Owen's comment doesn't make sense in that regard. If they're saying it's a theory in the colloquial sense - that it's a hypothesis/guess - that doesn't make sense either. Gravity is a term we give to a phenomenon that exists. The theories are what we use to understand what's going on, in accordance with the scientific method, etc.

Look at where we are today technology wise and where medical science has come to and we put a man on moon and next is mars and a human made probe is right now outside solar system. These are achievements and we understand a lot better now. Surely, we're nowhere near understanding it to it's full capacity? but we've done progress and that's certainly not a reason to stop thinking and perpetuate this type of mentality.

Level 4 isn't university talk... I am a physics student and I can assure you, you do not talk about things but rather just calculate and calculate more. The explanation she gave is much easier to wrap your head around, even with the last guy than it is when you get it explained in university. Usually it goes like this: The professor calculates things and just reads out what he or she is writing. Then they give it a name and a bit of history about it, if you're lucky. After that the next topic is "discussed". You'll have to turn in weekly assignments and they again, are just calculations but the lecture isn't nearly enough to actually solve them so you go online and read about it... a lot. That's where you get most of your information and actually learn about what does what. In short, university talk would be a level 7 or 8 on your scale.

I've always thought about gravity because for me gravity is very painful and never ending. I've had a birth defect in my spine that's caused constant pain since 1979. The best relief I've found was in the 90s when I got one of those inversion tables where you hang upside down by your ankles. I don't have to get completely upside down. Anything past parallel to the floor takes away the gravity pushing down on the base of my spine. It's also about the only way I can sleep, but I have to set an alarm for just a few minutes or all the blood runs to my head.
