I'd like to see more complex topics explained this way. Imagine an organic chemistry comic novel! I think people make a lot of topics seem way more complicated than they need to be, probably to make themselves feel important.
While I really enjoyed the comic, I don't think that it would actually explain anything to someone who had only been reading about quantum mechanics in some popular science articles.

> The point is so much of our conclusions are based off of these null hypothesis. Quantum mechanics, special relativity, and general relativity (I'm not sure which ones you're objecting to here) all have strong predictive power. The fact that we can build extensions of these theories and see experimental validation of those theories is itself support for the underlying principles. With quantum mechanics, you can expl…
That's like saying computers and laptops are so great -- we'll never need smart phones. Sure, classical devices / models are great and proven true, -- but that's still a limited view based on previous biases. I know that's a terrible analogy, but proving GR kinda works doesn't really disprove the Ether, either.
Quantum mechanics is an ur-example. Fundamentally, it's a set of mathematical equations only some of which have clear physical interpretations. What does the wavefunction actually represent, for example? To make matters worse, it also relies on mathematics that are well outside the comfort zone of most lay people--complex probabilities and renormalizable groups, for example (the latter caused consternation even within the physics community before the underlying mathematical basis was more rigorously developed). That leads popular description to rely on analogy that is at times more obfuscatory than helpful. But the underlying mathematics is quite well-understood, and we've built successful validations across chemistry, physics, and biology. As Feynman said, it's the most well-validated theory in history.
If you want to get a new scientific theory established, you need to do one of two things. The more common scenario is that you explain something that wasn't explainable beforehand. This is basically what quantum mechanics did. The less common scenario is that you find a much simpler but equally powerful explanation--this is what special relativity was.
The point of the Michelson-Morely experiment was to find the Earth's motion relative to the inherent reference frame of the universe (the ether). With the discovery of Lorentz invariance, Einstein's relativity theory basically said "it doesn't matter, any reference frame will do." Given also the many wavelength-dependent properties of light meant that you couldn't reuse the wave equations to explain electrodynamics, there was no reason to keep the ether around. Sure, you can build theories on the ether, but you're not getting anything simpler or more accurate by doing so, so what's the point?

Is that where they explain particle-wave duality, or is that where they pretend it's not an issue?

well it explains something, but a comic only goes so far
However, I'm very glad that SMBC sticks to the wonderful humour and I certainly don't want the author to change the comic. Just take it for what it is: a humour for those who already know about the topic, and don't pretend it's educational.

The value of scientific theories is their ability to make accurate predictions. Their reflection of the underlying physics and mechanics of the universe is a secondary concern--and indeed, most likely all of our theories are wrong by that metric. But if we can't tell that our theories are wrong by experiment, then the fact that they are wrong is only of philosophical importance. Quantum mechanics is an ur-example. Fu…
The implications are phenomenal, -- we could be in the presence of something HUGE, -- but people seem to rather "know for a fact" that we live in an empty vacuum devoid of anything but relics of a big bang.

What's the point? It's about understanding the universe! If the ether exists then it could mean an open-system exists in the universe, i.e. the big bang is still happening, -- or the laws of thermodynamics, i.e. entropy, are not set in stone because structure can be created with an open-system, -- or even general laws of physics: free energy because an open-system exists. The implications are phenomenal, -- we could…

I dispute that premise; it seems to me unlikely that we know anything from certain, and it seems to be that expanding our understanding of the world has had diminishing returns; fire has had greater returns than agriculture, and that engineering, than Newtonian mechanics, that than relativity and quantum mechanics, and so on.
From the above observation of the utility of scientific discoveries, if Ether theory nevertheless is closer to how the world functions, it seems very unlikely, and the conditions that enable it to exhibit its characteristics seem so alien to our present way of life that it is unlikely that funding research in such a direction gives better expected returns than research into other questions.
I'm starting to become skeptical of our understanding of quantum mechanics because we completely discredited a common theory with only one experiment over a hundred years ago: https://en.wikipedia.org/wiki/Michelson%E2%80%93Morley_exper... We never recreated the experiment again until Ernest Wilbur Silvertooth did about one-hundred years later in the 1980s. He found a possible connection to the Ether, but by this poi…
Ever tried to grasp how the detection of the gravitational waves already worked?
