      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.

      @@dynamics3261 She didn't understand him very clearly. She said what if it turns out that the world is 2D and we are living in a hologram? Nobody suggested we are living in a hologram, so she clearly had long lost him. What is being said is that just LIKE with a hologram (= analogy, not identity), there is more information in a 2D representation than meets the eye, basically. Because it is counter-intuitive to find that you cannot pack more information in to a 3D space than fits on the enclosing 2D surface of that space, e.g. a box or a ball shape.
      So the similarity to a hologram is that there is more information on the surface of an object than you'd expect. But a 3D space like a box, a room or the entire universe are truely 3D, unlike the hologram. - You cannot turn your credit card around to check and see what is at the back side of the security hologram or take a side view of a hologram - but of course you can take a look at the back of any 3D object in the real world though. The world is not a hologram, the analogy is aiming at the fact that just like with a hologram, any 3D object in the real world has a surface that can tell you about the information inside that 3D object by looking at its 2D surface, only. - That does not mean a 3D object IS a 2D object and nobody suggests that, but many people hear "holographic universe" on the Discovery Channel and jump on it, because they think they just heard about something crazy-amazing, well, on the Discovery Channel. (it still is amazing, though!)
      If you are interested in a good explanation, there is a series of talks by Leonard Susskind on RUclips, The Black Hole War, where he narrates a decades-long struggle with Stephen Hawking on all things Black Hole and this series goes along with his book by the same title, which is an interesting read also for laymen. Try the RUclips video first, it's free ;)

A broad vocabulary also comes in handy when learning second languages. If the children don't understand, they will either drop the topic or inquire further, depending on temperament and intelligence.

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.
