Discussion Overview

The discussion revolves around the nature of scientific theories, particularly in relation to the Big Bang Theory and String Theory. Participants explore definitions, implications, and the distinction between theories and hypotheses, as well as the public perception of scientific terminology.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants propose that a scientific theory is a hypothesis confirmed through repeated experimentation and observation, citing Newton's theory of gravity as an example.
  • Others argue that a theory provides a mathematical formalism to an idea, emphasizing that the strength of a theory is not solely based on its label but on the underlying physics and context within the field.
  • A participant asserts that the Big Bang is not a theory but rather a feature of a specific solution to the Einstein Field Equations, specifically referencing General Relativity and the FLRW metric.
  • Another participant references a definition from Wikipedia, suggesting that a theory is a unifying principle that explains a body of facts and is generally accepted but not conclusively proven, highlighting the distinction between scientific and mathematical proofs.
  • Some participants note that in science, there is no absolute proof, only evidence that supports hypotheses, and that the terminology can lead to confusion among the public.

Areas of Agreement / Disagreement

Participants express differing views on the classification of the Big Bang as a theory versus a feature of General Relativity. There is no consensus on the definitions and implications of what constitutes a scientific theory, leading to ongoing debate.

Contextual Notes

Participants acknowledge that the terminology used in science can be ambiguous and that the understanding of theories may depend on context and the surrounding scientific discourse.

Ok so a theory in science is a hypotheses that has been confirmed through repeated
experiment and/or observation (e.g., Newton’s theory of
gravity.)

So what's the deal with the Big Bang Theory and String Theory?

Are these not classed as scientific theories or is it to do with the wording maybe, its position in the sentence?

Cheers
 
Physics news on Phys.org
A theory, to put it simply, gives a mathematical formalism to an idea. F=kx is Hooke's law, i.e. a theory that describes the mechanics of the force exerted on a spring.

A theory doesn't make it "weak" nor does it mean that it is well-verified. One needs to fully understand not only the physics, but also the surrounding "atmosphere" within the field to know the degree of validity of a theory. That's why the general public is often confused on why a "theory" in one case is well-accepted, while another "theory" isn't. We don't put that much emphasis on the labels. We put more emphasis on the physics.

The Big Bang isn't a theory. The theory for the Big Bang is General Relativity. The Big Bang is a feature of a specific solution to the Einstein Field Equations in GR. This solution is called the FLRW metric, and it is the solution that seems to best describe the universe in GR.
 
Wiki says:

Definitively speaking, a theory is a unifying principle that explains a body of facts and the laws based on them. In other words, it is an explanation to a set of observations. Additionally, in contrast with a theorem the statement of the theory is generally accepted only in some tentative fashion as opposed to regarding it as having been conclusively established."

So a theory is generally accepted but not 100% proven?

There is no 100% proven in science, only in maths. In science we have evidence that indicates what is true and what is not. The more evidence you have (especially strong evidence from a variety of unrelated fields) the stronger the hypothesis. Theories tend to be things that are true beyond reasonable doubt but we are using English and unfortunately we use the same word to mean different things.
 
Cheers ryan that's clears things up for me.

Really? I never knew this. That explains a lot lol.
