Astrophysicist Explains Gravity in 5 Levels of Difficulty | WIRED
Ғылым және технология
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 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.

@@eagle3676 No, that's a dangerous perspective to look at these things. I bet you're not an expert on any of these things and are approximating what so many of these novel theories mean. We actually have come to understand a lot more than we did a hundred years ago. With the discovery of chaos theory, scientific theories actually have a bright future. 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. And I don't know why ppl like you think science (physics) is an open book and everything's just supposed to be discovered right away in an year or something, it obviously takes time. We're doing pretty good for beings this small compared to planetary and cosmic scales.
Fantastic review for me. Received my BSEE in 1972 and haven't reviewed temperature in statistical thermodynamics for half a century or considered it to be analogous to gravity in the way she said it. The expert was really good; he should put out scientific vlogs! But I have always loved science, even retired now at age 73.
If you can capture the child’s imagination and teach effectively a concept such as gravity, while simultaneously evoking pertinent questions and realizations, you have started the child on a lifelong journey of learning. She is an awesome teacher.

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 love these videos! I loved the reminder of the hologram part. I've seen it in documentaries before and it aligns really well with the whole spiritual concept of how existence and conciousness works. The pictures are very similar and I love how old intuition based observations start to get more and more reflected in science.

The only alignment is the spelling..hologram vs holistic
I love how the last two levels felt like equals talking about all the stuff they still don't know.

The explanation of the relation between space and time in that light speed measurement situation is actually mind-blowing. It made me inuitivitely understand the idea behind theory of relativity :o

When mentioning the square inverse law it sounds more like atmospheric pressure. For the effects vary due to matters relation to a solistrial body. The force/pressure isnt a pull in relation to the source but is being acted upon in all directions (to include internally). ie. An inflated sphere.

Im sorry i dont want to see small brain measurements
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.
I had the pleasure to see Janna Levin present as a guest speaker at Winton Capital in London. She was part of those gravity wave detection experiments she talks about in this video. It was a fantastic experience and to see how humble yet engaging she can be both in person and in this video!
The last guy is giving major final boss vibes. I was half expecting him to communicate telepathically.
