Overlap and Growth
Many researchers work at the intersection of cosmology and quantum
physics, particularly in fields like:
Quantum cosmology: Applying quantum mechanics to the early universe.
Quantum gravity: Theoretical approaches like string theory and loop
quantum gravity.
Multiverse theories: Hypothetical cosmological models arising from
quantum mechanics.
Growth Trends
Increased Funding: Quantum technology and space exploration have seen
significant funding increases globally.
Collaborations: Large-scale projects like the Large Hadron Collider
(LHC) and gravitational wave observatories involve thousands of
scientists.

How many, of the millions, accept relativity as a science

ChatGPT said:
>
The overwhelming majority of physicists, among the estimated 1–2 million
globally, accept Einstein's theory of general relativity as a valid and
well-tested scientific theory. Here's why:
>
Widespread Acceptance
Core Component of Modern Physics: General relativity is one of the
pillars of modern physics, alongside quantum mechanics. Relativity has
been confirmed through numerous experiments, including:
>
Gravitational lensing.
GPS satellite time corrections.
Detection of gravitational waves.
Black hole imaging (Event Horizon Telescope).
>
Acceptance Across Fields
>
Cosmology and Astrophysics: Nearly all physicists in these fields use
relativity to model the universe and its phenomena, such as black holes
and the Big Bang.
>
High-Energy and Particle Physics: Many theories in particle physics
(e.g., the Standard Model) are built on relativistic quantum field
theory.
Condensed Matter and Quantum Fields: Even fields seemingly unrelated to
gravity use principles derived from special relativity.
>
Dissent and Modifications
>
While relativity is widely accepted, some physicists explore its
limitations or propose modifications:
>
Quantum Gravity Theories: Relativity is incompatible with quantum
mechanics at very small scales, so theories like string theory or loop
quantum gravity aim to integrate them.
>
Modified Gravity: Alternatives like MOND (Modified Newtonian Dynamics)
are explored to address cosmological puzzles like dark matter and dark
energy.
>
These efforts are not rejections of relativity but attempts to extend or
complement it in extreme conditions.
>
Non-Acceptance or Skepticism
>
Dissenters are an extreme minority, often coming from outside the
professional physics community. Among mainstream physicists, skepticism
of relativity is negligible.
>
In summary, nearly all professional physicists worldwide accept
relativity within its well-established domain of applicability. Any
challenges to it are grounded in extending our understanding rather than
refuting its core principles.

***********************************************

Is it clear now? ChatGPT endorses relativity, even when fail to present
facts that led to acceptance on each field. In particular, cosmology and
quantum physics.

It refuses to explain the role of relativity in fields like solid state
physics, biophysics, industrial physics, medical physics, etc.

So, even when being highly conversant, refuses to concede that
relativity is confined to cosmology and particle physics, which have no
practical applications in this world.

Perhaps you'd have it easier to ask, "name a consequence held in each
of these sub-fields, not held in each of the other sub-fields,
held as a consequence of general relativity, and what are thusly
the empirical opinions that define the sub-field".
