Summary by a commenter in the link: Radio astronomy observations of Pulsars indicate that the Hubble Red Shift is caused by “Tired Light” rather than the expansion of the universe. When Hubble published his observations of red shifted light from distant objects there were two possible explanations that came to the fore. One, originated by Georges Lemaitre, was that the Universe was expanding. The other, from Fritz Zw…

Curious, I googled "In the radio astronomy of Pulsars we find that the shorter wavelengths of the leading edge of the pulse arrive before longer wavelengths. The velocity of light, c, is NOT constant but varies by wavelength" and something interesting came up: "interstellar clouds of electrons retard the velocity of radio waves in direct proportion to their wavelength" in an article from a 1968 edition of Scientific…

Look up Hannes Halven then, also very interesting.

On the other hand, scientific consensus isn't "groupthink", and being a contrarian doesn't automatically entitle you to other people's attention and time.

Or does it? There are plenty of examples where science got it wrong. Were it took years, even decades to get enough people to listen.* That's not the way science is supposed to work. Politics? Yes. But not science. I trust you can do the math from here. * And when the tides turn, these not even an acknowledgement, let alone an apology. Scientists shouldn't not be turning in their graves for lacking an apology. That l…

Well the Vatican did, to Galileo Galilei. Eventualy, took a while :P

Quote: If the universe is expanding, a strange optical illusion must exist. Galaxies (or any other objects) in expanding space do not continue to look smaller and smaller with increasing distance. Beyond a certain point, they start looking larger and larger. (This is because their light is supposed to have left them when they were closer to us.) This is in sharp contrast to ordinary, non-expanding space, where objects look smaller in proportion to their distance.

I just woke up and I don't get this...

> Lerner's ideas have been rejected by the professional physicists and cosmologists who have reviewed them. Are you being obtuse?

No. Probably just dumb and ignorant, thanks for asking. I don't equate "rejecting ideas" with "seen as a crank", but I only have a four year degree, so the linguistic nuance of academic backstabbing and gatekeeping is lost on me.

I'm sorry, I should have used different language. I thought you were saying the Wikipedia page held no criticisms of him at all.

Sounds like this commenter should write a paper.

why, it won't make it through peer review. high frequency light arrives first because it interacts less with matter. remember, c is only constant in a true vacuum. the speed of light varies as it travels through matter (refraction). there is a lot of "stuff" to interact with between us and a galaxy 14 billion light years away i wonder if the energy of empty space (yes, empty space has energy) plays a role in slowly d…

>why, it won't make it through peer review.

That was my point.

>Come up with a theory with testable set of predictions that isn’t just a patchwork of models glued together to explain data and then you’ll convince people. The dark matter crowd was able to convince quite a few people without hurdling such a high bar, not to mention stuff like string-theory..

> The dark matter crowd was able to convince quite a few people without hurdling such a high bar I don't know where you're getting this from. Dark matter models make lots of testable predictions, and they currently match the overall data set (which includes many different observations, not just the galaxy rotation curves that are most often mentioned) better than any other models. > not to mention stuff like string-t…

Not true, string theory made numerous testable predictions of what particles LHC should detect at different energy levels. AFAIK none of the predictions unique to string theory and it's different branches have panned out.

At this point I see string theory as more of a mathematical framework than physics

No, it didn't. Particular supersymmetric extensions to the Standard Model made testable predictions of what particles the LHC should detect at different energy levels, none of which have panned out.

String theorists like to take credit for those predictions (or at least they did until the predictions became notorious for their wrongness) because they claim that string theory is what justifies those particular supersymmetric extensions to the Standard Model. That doesn't mean we should let them get away with it.

Agreed, this his how things work in practice, but man, I wish we could do better. The question of whether new observations falsify the current theory is completely separate from the creation of a better theory. If the Big Bang theory is wrong, then it's wrong, and we just don't know how the universe began.

> The question of whether new observations falsify the current theory is completely separate from the creation of a better theory. No, it isn't. Theories don't get "falsified" except in rare cases and in the idealized fanciful histories of some philosophers of science. The idea that you can run one critical experiment that, if the results come out a certain way, will falsify a theory, is a myth. Scientific models lik…

> Theories don't get "falsified" except in rare cases and in the idealized fanciful histories of some philosophers of science.

Exactly. This is the problem.

Hey, I get it, we're not talking about Galileo rolling things down ramps here. Cosmology is huge and messy and there's going to be a lot of noise in all observations. I'm not claiming that the Big Bang is wrong, and I would never say that we should jettison decades of science because of some preliminary data from a weeks-old instrument. But, if the contradictory data were to mount, and be confirmed and reconfirmed by multiple researchers over time, well, I'd like to think that we'd have the intellectual courage to admit that this explanation doesn't seem right, even though we don't have a better one. We clearly don't, though.
