Discussion Overview

The discussion explores the advancements in cosmology since Einstein, focusing on various theories such as string theory, many worlds theory, and quantum loop theory. Participants express interest in the scientific community's views on these theories and their relevance to cosmology.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • Some participants inquire about the advancements in cosmology beyond Einstein, seeking clarification on specific areas of interest.
  • There is a mention of the general skepticism among astronomers towards string theory compared to theoretical physicists, emphasizing the importance of observable predictions in astronomy.
  • Participants note that the many worlds interpretation (MWI) is not testable and may not be relevant to astronomy, suggesting it is not a major focus for astronomers.
  • The standard model of particle physics is acknowledged as accepted among astronomers due to its experimental validation.

Areas of Agreement / Disagreement

Participants express differing views on the applicability and acceptance of various theories in cosmology, indicating that there is no consensus on the relevance of string theory and MWI within the astronomical community.

Contextual Notes

The discussion lacks specific definitions and assumptions regarding the theories mentioned, and the scope of advancements in cosmology remains broad and undefined.

Can anyone tell me how far cosmology has advanced beyond Enstein?

That's a rather broad question. Could you be more specific on what you want to know about?
 
Hi, Space Tiger.

It is hard to explain, i mean without malice ,what do the majority of scientists think about things like string theory, the many worlds theory ,or quantum loop theory, or any other theory that is after AE.

Well, I don't think astronomers view any of those things with malice, but there's no consensus in the astro community about their applicability. On average, I think astronomers view string theory with more skepticism than your typical theoretical physicist simply because they put less weight on mathematical elegance and more on observable predictions. Certainly, the standard model of particle physics is accepted amongst astronomers since its validity has been demonstrated experimentally in the relevant regimes. The MWI isn't testable and isn't relevant to astronomy anyway, so I doubt it's given much thought.
