Most instructional.

Makes you wonder what else our brains ignore.
Well, it's certainly an alternative explanation (sort of), but why do you think it is more convincing or credible?
Even though they are equally valuable, I would say that intuition can exist without rigour and this can be imagined by those who accept that we evolved from an animal state, ie rigour is the late-comer.
Fitting in with the thread title I would say that rigour is more in line with our conscious state, as it takes intention and effort, and that intuition is in line with our unconscious processes. the two working together to provide communicable ideas.I still don't know whether you agree with me that the unconscious state preceded the conscious one in our evolution. If this is the case then there certainly would have been a time when there was no (or less) equilibrium and possibly a useful way of looking at consciousness, ie, the development of it
I would say that intuition can exist without rigour

Looking for reasons to disregard the conventional red shift explanations, especially as they fit in with several other area of physics.
Because my intuition tells me it is. I know that sounds like a joke to the rational mind. I guess I've become more 'romantic' in the second half of my life, swinging from hard-nosed realist in the first half. I still have moments of doubt - am I going mad, to see things so differently from how I used to? - but to leave behind the 'life is nasty, brutish and short' theory of existence (exemplifyed by the big bang theory - there was a massive explosion, the universe is chaotic and uncaring, we are governed by a set of immutable laws, there is only one lifetime and you should grab what you can for yourself as selfishly as possible - the sun will explode one and day and everything will be destroyed etc etc) -all of this serves to lock thoughts into a doomish and self-interest mind-set that I now feel trapped me.
Halton Arp presents a theory based on observations, which is just as valid as other current theories. It's the mind-set perceiving an idea which makes it strong or weak. He may not be spot-on, but it ties in with my comprehension of re-incarnation, consciousness, creation, the way things work (based on my own observations) etc.
The Evolutionary Argument Against Reality
we go about our daily lives, we tend to assume that our perceptions — sights, sounds, textures, tastes — are an accurate portrayal of the real world. Sure, when we stop and think about it — or when we find ourselves fooled by a perceptual illusion — we realize with a jolt that what we perceive is never the world directly, but rather our brain’s best guess at what that world is like, a kind of internal simulation of an external reality. Still, we bank on the fact that our simulation is a reasonably decent one. If it wasn’t, wouldn’t evolution have weeded us out by now? The true reality might be forever beyond our reach, but surely our senses give us at least an inkling of what it’s really like.
Not so, says Donald D. Hoffman, a professor of cognitive science at the University of California, Irvine. Hoffman has spent the past three decades studying perception, artificial intelligence, evolutionary game theory and the brain, and his conclusion is a dramatic one: The world presented to us by our perceptions is nothing like reality. What’s more, he says, we have evolution itself to thank for this magnificent illusion, as it maximizes evolutionary fitness by driving truth to extinction.
Getting at questions about the nature of reality, and disentangling the observer from the observed, is an endeavor that straddles the boundaries of neuroscience and fundamental physics. On one side you’ll find researchers scratching their chins raw trying to understand how a three-pound lump of gray matter obeying nothing more than the ordinary laws of physics can give rise to first-person conscious experience. This is the aptly named “hard problem.”
On the other side are quantum physicists, marveling at the strange fact that quantum systems don’t seem to be definite objects localized in space until we come along to observe them. Experiment after experiment has shown — defying common sense — that if we assume that the particles that make up ordinary objects have an objective, observer-independent existence, we get the wrong answers. The central lesson of quantum physics is clear: There are no public objects sitting out there in some preexisting space. As the physicist John Wheeler put it, “Useful as it is under ordinary circumstances to say that the world exists ‘out there’ independent of us, that view can no longer be upheld.”
So while neuroscientists struggle to understand how there can be such a thing as a first-person reality, quantum physicists have to grapple with the mystery of how there can be anything but a first-person reality. In short, all roads lead back to the observer. And that’s where you can find Hoffman — straddling the boundaries, attempting a mathematical model of the observer, trying to get at the reality behind the illusion. Quanta Magazine caught up with him to find out more.

But how can seeing a false reality be beneficial to an organism’s survival?
There’s a metaphor that’s only been available to us in the past 30 or 40 years, and that’s the desktop interface. Suppose there’s a blue rectangular icon on the lower right corner of your computer’s desktop — does that mean that the file itself is blue and rectangular and lives in the lower right corner of your computer? Of course not. But those are the only things that can be asserted about anything on the desktop — it has color, position and shape. Those are the only categories available to you, and yet none of them are true about the file itself or anything in the computer. They couldn’t possibly be true. That’s an interesting thing. You could not form a true description of the innards of the computer if your entire view of reality was confined to the desktop. And yet the desktop is useful. That blue rectangular icon guides my behavior, and it hides a complex reality that I don’t need to know. That’s the key idea. Evolution has shaped us with perceptions that allow us to survive. They guide adaptive behaviors. But part of that involves hiding from us the stuff we don’t need to know. And that’s pretty much all of reality, whatever reality might be. If you had to spend all that time figuring it out, the tiger would eat you.
So, to sum up.. you can question your intuitions if you choose, it's the start of a journey, not a conclusion. A clue might be that, if your intuition is telling you something concrete about a field you have little or no personal contact with, then there may be other factors at work, as described above
