This other way around. What they call the physical is information. Hence why digital physics is growing as an idea as well as the simulation hypothesis and the idea that the physical world is virtual. See here
>https://arxiv.org/pdf/1703.00058.pdf
if you want the real deal and not bostrom's false idea of an objective self existent matter based world which is doing the projecting of this world.
Bostrom's idea, that consciousness is also virtual, is false and misunderstands that it is consciousness that does the computing and the physical world that we are immersed 'in' is the result of this computing by consciousness in a real, non simulated mind, as opposed to a simulated mind. So consciousness=real, physical world=simulated in consciousness/mind. As max planck already knew. Matter is derivative of mind.

By the way, in this paper here
>>14292850
when it says
"We investigate this question based on the assumption that if the system performing the simulation is finite
(i.e. has limited resources), then to achieve low computational complexity, such a
system would, as in a video game, render content (reality) only at the moment that
information becomes available for observation by a player and not at the moment of
detection by a machine (that would be part of the simulation and whose detection
would also be part of the internal computation performed by the Virtual Reality
server before rendering content to the player)."

The "system performing the simulation" that has "finite
(i.e. has limited resources)" is an individual consciousness, not the big consciousness or server or 'the all mind' or the creator. The finite resources are a constraint of the 'individuated unit of consciousness'. This finite resources of our consciousness are the reason for the speed of light, heisenberg's uncertainty principle etc.

Protein causes afferent arteriole constriction meaning that the blood pressure drop in the glomerulus.

In normal language this lowers filtration rate of you kidney which isn’t bad in healthy ones but if you have kidney insufficiency your filtration is already too low, making it even lower is detrimental.

OP here, I'm a fucking idiot: looking back at my own chart I see something I missed.
Red and blue account for way more solar energy than the tiny slither of the visible light spectrum that is green. That almost explains it, "why reflect green?" "because red and blue account for more solar energy"
>>14290426
>The main reason why green light is not useful to plants is because it is poorly absorbed by chlorophyll.
Is there a obvious trade-off going on. Is there anything specific we can point to about the chemical structure of chlorophyll that we can see as a implicit 'rejection' of absorbing green for some other advantage? Or are these things too complicated to explain in nice neat terms of 'trade-offs'?

Chlorophyll and related structures are actively being researched,
Depending on how much you know or remember about orbitals in organic compounds will of course determine your basic understanding of papers. I have no problems saying the computational models mentioned in many of the papers I browsed are above what I studied.
in situ is further complicated by chlorophyll interactions with the photosystem.
