This is nice because you share knowledge and then you come up with a conclusion, it's like syncing your information with someone.

[@Baerchenization]

@@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 KZbin, 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 KZbin video first, it's free ;)

[@conanotoole]

How is it a theory?

[@hayleygun]

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.

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.

@@NoNewfriendss Brans Dicke is the way. Einstein himself practically admitted that general relativity could not accurately describe quantum mechamics and thus is flawed. Everyone thinks that Einsten created General Relativity and stopped doing anything, when in actuality he kept researching unified field theories for 30 years. Now CERN and others found some anomalies and ended up with the Higgs Boson scalar field, which was theorized by Einstein-Bose' Condensate. Einstein had to add those because it (His UFT) would've been the same as Nordstrom's theory of gravitation

[@dakshs9528]

Gravity is relative. Just like velocity. That's why.

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

I can’t imagine how it must have felt for Newton when he had that Aha moment. He must have been almost scared at how potentially massive the theory he had just stumbled upon was. He must have felt the literally weight of what he was seeing.

[@SuperSchnelle]

I THINK that in many colleges and universities they teach many procedures and mechanisms and do not encourage thought and analysis, the exams measure a note (the information that you memorized surely you forget in a week) they do not decide if you really learned or understood why something is thus, even math is taught with mechanical procedures that require verification to understand why it is done that way.

[@billord]

@@SuperSchnelle I would disagree. In university maths the emphasis shifts heavily onto proof, so that students understand theorems and procedures when they learn them.
