Reply to comment by JanetYellenThrowAway in If collagen is a protein, and proteins are broken down during digestion, why would collagen or collagen supplements be beneficial? Is it just hype? by skepticated
Are you not bothering to read some of the links that others have provided, that demonstrate that collagen may not be completely digested as most proteins are, and collagen derived polypeptides can indeed enter the circulation and are measurable? And that there is accumulating evidence from clinical trials that oral collagen supplementation likely indeed has objectively measured affects on skin and wound healing?

More people should read “The Structure of Scientific Revolution” by Kuhn. There really are no sudden breakthroughs in science, at least as the general public tends to understand, it’s always some kind of gradual change or a collective buildup of many ideas over periods of time.
When it happens, it’s always evolution. In hindsight the stories are always told like it’s some sudden new idea.

Brilliant! Thank you. I will have to read parts of this more than once to fully understand, but I appreciate you taking the time to put it all there.

Were those the extremely limited ones (like a 3x3 grid of pixels)?

I would be careful taking these kinds of ideas too seriously. This starts to get too close to metaphysics for my liking, and I don't believe any physicist genuinely believes or could verify this if they wanted to. It's akin to quantum woo in my mind.
Also, as the other poster already said, saying "quantum theory" is a better description of the universe is nonsense; they describe entirely different things. Although it is no secret they are incompatible as of now, this just indicates one or both may be incomplete but not entirely wrong.

Wow, what a great answer. I think my poor brain needs time to digest all of this.
Thank you for taking the time to be so thorough.

Your body is constantly breaking itself down, catabolism, and building itself up, anabolism. Your body breaks down its own, endogenous, collagen and builds it up. By consuming collagen, your body can break it down rather than breaking down your endogenous collagen. The metabolites may or may not be used to build new tissue, but the benefit from it is supposed to be by decreasing catabolism without affecting anabolism.
I thought something similar, but with amino acids. I thought they would be directly used to make new proteins. After me wasting ten minutes of class time arguing with my teacher, this is how she explained it to me. The end results of metabolism may be used to build new amino acids, or in this case collagen, but the value comes from decreasing catabolism.

I don't think it's out there at all and it could be a fascinating avenue of research haha. I wasn't trying to be dismissive - I just know there's been a few papers put out speculating on a changing value of speed of causality, just I don't think there's been enough evidence or testability to really "mean" anything scientifically

Reply to comment by AxelBoldt in In Parkinson disease, why doesn't the adrenal gland fill the dopamine deficiency? by Actual-Pumpkin1567
That's exactly right! In the synthesis of dopamine, converting tyrosine to L-DOPA is the slowest step, so having extra L-DOPA available significantly increases dopamine production.

The man didn’t have to come up with the idea/notion of some gravitational force. It was the formulaic derivation and idea that multiple seemingly-unrelated phenomena were indeed governed by the same thing which made him a straight thug.

If that happens you should power cycle and reboot. So maybe take a nap and when you wake up your brain will work again.
