Discussion Overview

The discussion centers around the concept of a "theory of everything" (TOE) and whether its potential discovery would signify the end of physics as a field of study. Participants explore the implications of such a theory, its feasibility, and the ongoing relevance of physics in light of its possible completion.

Discussion Character

  • Debate/contested
  • Exploratory
  • Conceptual clarification

Main Points Raised

  • Some participants express skepticism about the imminent discovery of a TOE, suggesting it may take much longer than a few years, if it is possible at all.
  • Others argue that even if a TOE is formulated, it would not mark the end of physics, as there would still be numerous applications and unresolved phenomena to explore.
  • Concerns are raised about the implications of a TOE potentially leading to a stagnation in new discoveries, with some participants reflecting on historical claims of the "end of physics" that proved incorrect.
  • Participants note that a TOE might provide a framework for understanding fundamental interactions, but many complex issues and applications would still require ongoing research and interpretation.
  • There is a discussion about the role of theoretical physicists in interpreting and applying a TOE, suggesting that their expertise would still be necessary even after such a theory is established.
  • Some participants express a desire for continued discovery, indicating a tension between the pursuit of knowledge and the fear of reaching a definitive endpoint in understanding the universe.
  • One participant references Roger Penrose's view that reconciling existing data would still yield significant discoveries, regardless of a TOE's existence.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether a TOE would signify the end of physics. There are multiple competing views regarding the implications of such a theory and the future of research in physics.

Contextual Notes

Some statements reflect uncertainty about the timeline for discovering a TOE and the nature of its implications. The discussion includes references to historical perspectives on the state of physics and the ongoing challenges within the field.

Hey.
I've heard from several physicists that in the next few years, physics might come to an end after completion of the theory of everything and that basically, there's not going to be anything new to research in physics.

What are your thoughts on the matter? Do you think such a theory is possible? Are we close to formulating it and will it indeed end physics?

In the next few years?

Maybe in the next 100 years we will have a theory of everything, but it's highly unlikely.

It is more likely that we will become less optimistic about a theory of everything. We may even have theories of why there is not a theory of anything. Who knows? We are a long way away...

Plus, even with a theory of everything, the possibilities in physics and engineering is limitless
 
In 1992 I'd heard from Fukuyama that history has already ended.
10 years later a quick walk through Manhattan showed me he was rather wrong.

Read some texts from end of 19th century. Physics was already just-just-ending over 100 years ago.
 
Even if a "theory of everything" was created (meaning some equation that governs all fundamental interactions), there are still lots of issues with how that relates to larger scale phenomena. For example, General Relativity describes gravity very accurately, but you still have entire journals dedicated to applications of the EFEs in different theoretical cosmic situations.
 
Not to mention there are many seemingly simple phenomena which has yet to be explained. A consistent theory of friction for example.
 
Even if we find a Theory of Everything in the next couple years it will definitely not be the end of physics. It will just provide us with a consistent frame to work with. There are endless applications that will require physicists and engineers to design/test/model, etc. etc. etc.

Well, definitely not engineers but will there be a use for theoretical physicists?

Sure! Why not? Not everyone is going to have the brains to understand and interpret the theory of everything. If String Theory and LQG are any indicators as to what the language of the TOE might be in then we're definitely going to need Mathematical/Theoretical Physicists around to interpret and improve upon the theory.

There is also the problem of HOW we can apply the new Theory of Everything. We can easily state once we've found it that yes we know how everything works! But how can we take that and apply it to something that might be of some use to society. As I have already stated the language of the TOE will be very complex and I feel like what we now call theoretical physicists will be the ones who step in and suggest ideas of how to employ it.
 
I see. Thanks for the answers.
All I can say is I hope they won't find it. It'll suck if we'll just know how the universe works and end of story.
It's this little contradiction of scientifically minded people that we want to know, and yet we never want to know everything so that there's always something new to discover.

There's no such thing as a "theory of everything".

Roger Penrose wrote that even if we stopped collecting and discovering data and facts, there is still a lifetime of reconciling all that information and making discoveries from what we already have.

Well, I wasn't taking the term 'theory of everything' literally of course. I was specifically asking if the discovery of it would result in the end of the science of physics, and also how likely we are to see this theory anytime soon.

But isn't THAT the whole implication of this TOE being the "end of physics"? That someone thinks that after such discovery, no more new and interesting stuff are left?

So yes, it is literally THE theory of everything! And that is a fallacy.

Well, glad to hear that it's a fallacy!Thanks everybody!

The statistics show membrane has only posted in General Discussion. Posts don't count in this forum.

By the end of the 1950's science had discovered all the natural chemical elements of the universe.

Has the science of chemistry come to a grinding halt and all the chemists gone to pasture?

If they did, some of us would have a bazillion :redface:.

So either the counter state or the posters here are destined to loose mass, this might be my last post in this section.

Bazillion is an accurate scientific quantity by the way. I believe it is a jllion zillion.

The end of physics will come with the TON.
