or was it just the result of the natural course of scientific discoveries
>>8594953You can ask him in hell.
If you think of Truth as something that exists "out there" outside our purview, then I'd say the second one.If you had never studied anything in your life, it wouldn't make any of the information you have today any less "existing" outside of your awareness.
>>8594953After realizing pretty much all of special relativity is a result of Minkowski geometry, there is the obvious question of what if we generalize this to curved spaces.How you get gravity from that, given only the knowledge of physics they had then, idk.
>>8594953Perceived curved light from acceleration ---> must be curved space.Not too hard.
All these convoluted explanations of gravity are the modern-day equivalent of ptolemaic orbits. There's just something simpler there that we can't see.
>>8594969I disagree. Riemannian geometry became Italian school mathematics and physicists didn't know anything about it. The formulation of special relativity using a metric was also the work of Minskowski, and Einstein head to learn it.>>8594953Lots of people worked in that direction.The first metric theory of gravitiy was that of Nordstromhttps://en.wikipedia.org/wiki/Nordstr%C3%B6m's_theory_of_gravitationThere is also a famous Einstein-Hilbert disputehttps://en.wikipedia.org/wiki/Relativity_priority_dispute#General_relativity_4Hilbert was done with the theory earlier than Einstein, and he was the one who knew the math, but Einstein came up with the general field equations.And generally, there are articles from a decade after GR came out that make it clear they don't get the math (or it's implications) of coordinate transformations vs. curved spaces.It's like with spin, the early physicists working this out had no insight into Lie-algebra homomorphisms, everything was foggy
>>8595026(cont.)Here are some physicists who came up with metric ideas, half of them have their own Wikipedia articles Bergman Coleman Einstein (yay) Einstein–Fokker theory Lee–Lightman–Ni Littlewood Ni Nordström's theory of gravitation Page–Tupper Papapetrou Rosen Whitrow–Morduch Yilmaz theory of gravitation Bollini–Giambiagi–Tiomno Deser–Laurent Whitehead's theory of gravity Einstein's GR Fourth order gravity f(R) gravity --- this is a straight forward extention:https://en.wikipedia.org/wiki/F(R)_gravity Gauss–Bonnet gravity Lovelock theory of gravity Infinite derivative theorem gravity Bekenstein Bergmann-Wagoner Brans–Dicke theory Jordan Nordtvedt Thiry Chameleon Pressuron Hellings–Nordtvedt Will–Nordtvedt Lightman–Lee Rastall Rosen (1975)Extentions of the Pseudo-Riemannian framework are Belinfante–Swihart Einstein–Cartan theory Kustaanheimo Teleparallelism Gauge theory gravityAnd then different classical force theories on the one hand, and quantum shizzle on the other
>>8594953It's always easy to say that theories are obvious or even trivial after they have been conceived. As a layman it's also easy to ignore how difficult the details of working out a theory is, meaning working out phenomenology, consistency checks etc. These days there are shitloads of introductory books on the topics that are presenting the concepts and mathematic in a very comprehensive way. Back then it wasn't as easy. Every little thing needed to be worked out, double checked and interpreted. The math was very new as well back then and there were no computers you could have used to make quick plots etc.
>>8594959WRONG!Schrodinger's cat proves otherwise
>>8595235*canned audience laughter*
>>8594953I think it was inevitable but nonetheless impressive
>>8595235[insert long discussion about time and causality]
>>8595251The same way that people are impressed with works of art. "I could never have done what he did!" Obviously. You didn't spend your whole life working on that. He did. You spent your whole life doing something else.
>>8595026>I disagree. Riemannian geometry became Italian school mathematics and physicists didn't know anything about it.So it would be like going up to a physicist today and expecting them know what a Derived Stack is?
>>8594953The mane stream meteor says otherwise.But, ignoring those opinions, its POV was impressive.Also, he was jewish, so it implies he is superior.
Seeing as his theory about gravity waves has found a foothold in modern day science, could further research on the topic reveal something further about gravity that could potentially block is affects and create some kind of anti gravity device?
IT WAS JUST A MATTER OF TIME HAHAHAHAHA. Fml. It's 05:43 here in the NL and I can't sleep anymore. Why do I keep waking up between 4 and 6am /sci/. After I wake up I can't fall a sleep anymore
>>8595792Seeing as philosophy is the most important element of science let me kick us off with a Socratic principle:>What IS is. One can not talk about something without being able to answer that little question. So yeah, let me know and I'll build your handheld gravity device. Not like I have some fucking sleeping to do
>>8594953It was hard. Just like Newton, yeah gravity was there all along but work it out
>>8595268Yes. Except I think the learning barrier to anything (properly) geometrical is smaller than to derived functors etc.
>>8594953>the natural coursewat
>>8595835>A matter of timeHoly fuck. He did say general though. That's the gravity one
>>8595841IS means an equality of two substances, or in some cases for one element to pass through another so as to become part of another for an infinite amount of time.So if that's the case and is IS actually IT'S, then answer the fucking question. If gravity could potentially be blocked just like we can block light, would such device be detrimental or instrumental in the innovation of antigravity?
>>8596377This. Is this a question on predestination? Was Einstein an anomaly against a predetermined course of the universe? Is a certain scientific discovery required before another can happen?
>>8596369A derived stack is geometrical. https://ncatlab.org/nlab/show/derived+algebraic+geometry
