===New theories===
{{User:UBX/CanLearnALot}}
{{userbox|id=[[File:Gnome-x-office-drawing.svg|45px]]|info=This user contributes '''[[scalable vector graphics|SVG diagrams]]''' with [[Serif DrawPlus]] X4.}}


{{-}}
Theories like [[causal dynamical triangulation]] (CDT) and [[spin network]]s look like the right direction to [[quantum gravity]].


{{User:Shāntián Tàiláng/Userboxes/Atheism}}
CDT takes logical approaches:
{{User free speech}}
*spacetime is quantized at small scales and appears as smooth, curved spacetime at large scales,
{{User Infofreedom}}
*that timelines must agree and casualty is preserved - not just describing, but possibly ''explaining'', the very nature of space and time itself,
*interesting is it's automatic [[fractal]] nature.
*perfectly simple (minimum number of ''essential'' assumptions) and extremely appealing.


{{-}}
''Not'' [[string theory]] or the like - which make ludicrous assumptions that particles "are" strings or membranes or whatever and then require extremely complex modifications to spacetime just for consistency ([[Calabi–Yau manifold]]s? Really?).
*The worst part of string theory is right from the very beginning, is the assertion particles "are" strings etc. How can we ever know that experimentally? We can sit down speculating/guessing/modelling what particles "really are" (only to change again and again anyway in the future) a much as we like:
::''"let's pretend '''everything''', even the "fabric" of space and time, is vibrating strings or springs or trampolines or twirling tops or spinning wheels or pendulums or twiddling knots/links or... then there are a number of fundamental normal modes/rotational frequencies/tensions of these ... and everything in the universe is derived from these fundamental things..."''
:It's weak - just making stuff up just for the sake of explaining physical phenomena, ''and yet'' the maths is ludicrously excessively complicated just so it works... CDT is ''not, at all'', like that.
*Should the unification of forces really be related by the number (10, 11, 26...) of spacetime dimensions??...
*Yes, it may combine GR and QFT and has passed internal consistency, but proponents seem too confident that it "is" the only approach, that "only all of the good ideas" come from string theory...
*What happens when new forces are found - shall we hope they still fit into the theory, or insert more dimensions, or what?
*Without question - the [[simple harmonic oscillator|SHO]], classical or quantum, or any form of linear [[normal mode]] oscillations, are the most ''inanely dull'' physical systems to ever solve for.. Yes - SHOs are important systems for [[perturbation theory]] methods, and oscillatory systems are ubiquitous and can be modeled by linear oscillations... but even the idea of something oscillating linearly is extraordinarily boring and tiresome. This idea is used in string theory. ('''Non'''-linear [[chaotic]] oscillations are much more interesting).

===Formulations and spaces===
{{User:3p1416/Userboxes/Keen mathematician}}
{{userbox|id=<math>E^2-p^2=m^2</math>|info=This user understands [[physics]] at an '''[[Undergraduate education#English, Welsh, and Northern Irish system|undergraduate]]''' level.}}


{{-}}
'''Quantum theory:''' Has the [[path integral formulation]] using [[Lagrangian]]s had its day? Phase space formulation in QM and replacement of wavefunctions by Wigner functions offers new insight - no need to take sides with position/momentum representations as they're on equal footing.


{{userbox|id=[[File:Nuvola apps bookcase.svg|45px]]|info=This user is a '''[[bibliophile]]'''.}}
'''Relativity:''' Space and time are always deeply mysterious, in classical mechanics and [[general relativity]]. GR itself apparently has a number of flaws (but then which physical theory is truly perfect?), one of them is that "events" are points in spacetime. Do points really exist in nature? How can we even physically define a point in spacetime? In superspace (and other spaces I haven't encountered) points themselves are replaced by spaces, no points actually exist. According to the [[ADM formulation]] of GR, space itself is 3d and curved, and time-dependent (dynamic).
{{userbox|id=[[File:Aiga railtransportation 25.svg|30px]]|info=This user's favourite transport is the [[train]].}}
{{user:UBX/chess}}


===Fractals, chaos, non-linearity, everywhere===

Rather than changing the integer number of spacetime dimensions, and postulating wave or field or evolution equations of integer order, newer methods of
*(stochastic) [[fractal]]/[[multifractal]] geometry filling continua of dimensions between 0 and 3 or 4, and
*using [[geometric algebra]] and [[fractional calculus]] (or even [[fractional differential forms]] or fractional [[geometric calculus]]?), for example [[fractional quantum mechanics]],
look like the right way forward. "Particles/waves/fields" may be replaced by fractal structures which propagate [[self-similarity|self-similarly]] through spacetime.

Given how ubiquitous fractals are everywhere (literally everywhere, one way or another), a better notion of space and time may be dynamic and curved fractal spaces. ''Replacing'' the description of "particles/strings (etc)" described by wave-like or field-like probability amplitudes, by a ''fractal-geometric probability amplitude'' propagating through curved dynamical space, seems very appealing. Interpreting the constituents of [[matter]] always transforms, first "[[particle]]s" ([[classical mechanics]]), then [[wave-particle duality]] ([[quantum mechanics]]), then [[field (physics)|field]]s ([[quantum field theory]]).

A non-linear, but simple, theory based on '''fractal geometry'''... should connect GR and QFT with [[SUSY]]?... Not yet sure how ''exactly'' to do that mathematically and make everything work though...

'''Drawing and diagramming everything;''' so that information and meaning is actually transferred to a reader as directly and simply as possible, happens to be my obsession. Ironically I'm not very good at it, usually due to my sore misunderstanding of the concept to draw/diagram...

Drawing for recreation (for instance mathematical patterns, [[technical drawing]]s, people in [[Japanese manga]] style, building [[architecture]], and when a kid: almost every form of European [[train]], and so on...) is also very fun, although I can do technical graphics I'm not good at artistic at all! (much of these creations end up in the bin or deleted instead of storage for later leisure!!)...


|group1 = ''Fundamental [[physics]]''
IMO There is nothing like drawing: simply a pencil on paper allows one to literally release imagination pictorially in no other precise (or vague/mysterious) way, and can be viewed later any number of times to think and rethink the concept of the image endlessly. Of course there is immense diversity of drawing tools and materials mechanically and electronically for any purpose required, to amplify the power of the pencil and paper...

'''Isn't it sad that:'''
*in all years of civilization - science, mathematics, technology, industrialization have developed far slower than they could have because of irrelevant and empty customs, religions, and personal preferences of the "higher-uppers"; "leaders" of a country or a "inflexible generations" blocking the way? (i.e. any case where people are forbidden to think outside of some falsely obscure box, and make new discoveries in the service of civilization with mutual respect to the planet)
*how many potentially brilliant minds have been (and still are) WASTED in slavery and/or poverty (which ought to be collaborative team work with mutual respect between so-called "peasants" who build the land and need to be rewarded with wealth from it and "leader/s" who rule), and wars?

This account is not named after the place Maschen in Germany, Harburg: it was coincidence to combine "Machine" into a "name-like" term.

Background

[edit]
