Fundamental physics Definition and 19 Threads

I found this interesting discussion here in Physics Forums (https://www.physicsforums.com/threads/are-all-symmetries-in-physics-just-approximations.1005038/) where the topic of all symmetries being approximate is discussed Is there any model (for instance, some type of spacetime metric or...

The Hubble tension or Hubble discrepancy is a contradiction between the Hubble constant as measured today, and the Hubble constant as measured in the early universe and extrapolated to today. @mfb recently listed the relevant measurements. There are some threads about this in the Cosmology...

I know the textbook definitions and descriptions of the phenomenon, but I'm hoping for a fundamental WHY. I can see that when a water wave passes an obstacle, the wave spreads out into that object's shadow because the wave's energy is not constrained to any direction and so it will move out in...

I see that this has been discussed before, but the old threads are closed. As Carl Brans and others note, it seems too big a coincidence to ignore. Why is exotic smoothness "good" (in the sense that it permits richer physics or something like that)? Exotic Smoothness and Physics,arXiv "there...

Hello. I think I don't understand very well the Paul Steinhardt's cyclic model of Universe(s). According to Paul Steinhardt, 2 universes get closer. Then, there's the big bounce, which products effects like a big bang. If 2 universes get closer, they have a (relative) speed ( speed is the...

I'm in a graduate course in Physics to obtain a master's degree. I have a major in mathematical physics and my main interests are General Relativity (GR), Quantum Field Theory on Curved Spacetimes (QFTCS), and usual Quantum Field Theory (QFT) itself. My interest is in the fundamental physics...

I have this fundamental question about stress and strain. If we apply same Force on two different objects of same geometry in the same configurations, will they experience the same stress? If yes, then does it imply that stress is independent of the internal material properties?

Does JWST has any significance in fundamental physics research? What kind of questions would we get answers to?

I am a condensed matter grad. student, but do not work on Graphene. I am interested in learning about the fundamental physics in graphene (e.g. the need to use Dirac equation to represent the motion of electrons). I know that many books are there, but not all are geared towards fundamental...

I want to ask that what should be considered the most fundamental in physics I.e. whether the Standard Model or Dimensional units or the fundamental forces?

I thought this post was hilarious, especially the paragraph right before the first Update.

Online nominations are now being accepted for the 2013 Fundamental Physics Prize. If you haven't heard of this new initiative, see http://www.fundamentalphysicsprize.org/news1 . The full information is included below. Thank you for your time, Rob Meyer Administrator ___ Online...

Who said is there any money in Physics? http://fundamentalphysicsprize.org/news.html New annual US$3 million Fundamental Physics Prize recognizes transformative advances in the field Inaugural nine recipients of the Prize receive US$27 million in aggregate, all of whom agree to form a...

There is an article in the field of relativity (not homework) that need evaluation, please advise institutes that might do that??

I came across this. I guess you could say. F→∏ A l Z ...or... F→∏ AlZ The third symbol is supposed to be upside down. Does that matter?(The ∏ symbol) And between the symbol A and Z the line is supposed to be a tall line. (Not an L or I) Does this make sense?

http://blog.wired.com/gadgets/2008/08/bell-labs-kills.html" Six Nobel-prize worthy research came from that lab, including the invention of the silicon transistor, and the laser! It was a business decision by the parent company but, I think it's a very myopic business decision to abandon...

Hey guys...I always tend to ask a lot questions...so I was wondering if you guys know of some books out there which is very fundamental and explains its reasoning on every step of its way as if it was made for kindergarten but covers advanced topics? Fields I am interested in...

Howdy all, I've begun to get started in learning about physics, but am still lightyears removed from any of the mathematical aspects of the science. Thus I am now looking to move from themes to numbers (and I'm kinda nervous :rolleyes: lol) Anyway, here's where I'm heading currently...

What is the most fundamental physics that we can observe directly with our senses?
