Re: Quantum Mechanics: established fact?

Read your post Mr. Hansen,
At one time "science" was regarded as something
based on repeatable observations. But recently
science now includes social science, statistics,
tea leaves, bumps on head and anything else
that is politically correct.
Cosmological origin - assuming there was one -
cannot be repeated, the evidence is the universe
always existed, as no contradiction of conservation
of mass-energy has been found. BB as a scientific
theory is DOA, but it may have value as a working
conjecture, which is fine with me.

That's religious, there is NO evidence for a BB.

I'm surprised that you've missed this stuff. Big Bang theories are
based on general relativity. You know, that "greatest blunder" can't
get a static universe stuff? Intuitively, it seems pretty obvious that
if stuff is moving away from us, then it was a lot closer in the past
(cite redshifting versus distance as evidence). Structure of the
background radiation, every once in a while rags like Physics Today
publish new comparisons of measurement with theory. Gravitational
lensing apparantly caused by clumps of the dark matter that some wrote
off as fiction. Theories of Big Bang nucleosynthesis correctly predict
ratios of primordial isotopes.

There's actually quite a bit more than zero evidence there.

Let's be careful, there is no evidence that the
so-called "Red Shift" is of Doppler origin, that's
an assumption. And the idea that CMBR are
radiation remanents of the BB is really pushing
strange assumptions, again without evidence.

And there's no evidence that time dilation of satellites in orbit is a
geometric effect, although it is consistent with geometric theories of
gravity. There's a lot of things we can say that the redshifting is
not, such as an attenuation of bluer wavelengths. Line spectra are
shifted toward the red in the manner expected of the Doppler effect.
That's evidence, Ken. It validates the theory. And the
other-mentioned are also consistent with the theory, and inconsistent
with a lot of alternatives.


IMO BB is a conjecture requiring the suspension
of the laws of physics at some point (as PD said)
without any valid replacement, A.K.A. a MIRACLE,

Who cares? Excluding that point is a mature theory and a rich body of
evidence. Surely you don't want to say, for instance, "We don't have
physics to describe the attosecond after the Big Bang, therefore the
ratios of primordial isotopes tell us nothing about the expansion of
the universe." Between the point that baryons froze out and the point
that neutrons bound into nuclei is well described by the theory. It
looks like the universe was a lot smaller than it is now, and claiming
poor understanding of the physics at the beginning doesn't make the
evidence point to bigger or static.

therefore we have no theory for the MIRACLE and
so BB is NOT a theory, though an interesting
conjecture, and has the same weight as theism,
aka religious.
Ken

Yeah, and people say the same thing about quantum mechanics and special
relativity. E.g. Spaceman shouting for the undiscovered forces and
influences that make it appear that time goes slower for a moving
particle, when we should know it really doesn't. Anybody can wave his
arms around and propose an alternate explanation of varying quality for
the evidence, but an alternate explanation doesn't de-validate a
theory.
