Hey, I thought about you yesterday! But I'll be damned if I remember what I wanted to ask…

Ah. Mass-energy equivalence.
Wikipedia says at
https://en.wikipedia.org/wiki/Mass–energy_equivalence#Practical_examples
>The electrical energy produced by Grand Coulee Dam's turbines every 3.7 hours represents one gram of mass. This mass passes to electrical devices (such as lights in cities) powered by the generators, where it appears as a gram of heat and light.[34] Turbine designers look at their equations in terms of pressure, torque, and RPM. However, Einstein's equations show that all energy has mass, and thus the electrical energy produced by a dam's generators, and the resulting heat and light, all retain their mass—which is equivalent to the energy.
Is it true? Does this mean that if that amount of passed through water in four hours was weighted before and after, it would weigh a gram less after the turbines than before them? Does it mean that the when that much water evaporates from oceans/whatever and goes to the upside of Grand Coulee Dam, it "gains" a gram in mass?

The best way to think about wavefunction collapse is decoherence. Essentially exchange of energy with the surroundings is a "weak observation" that makes the wavefunction more localized. And the timescales are incredibly tiny, however not so small that for tiny particles we can't measure it. We have measured decoherence taking place. So for all realistic situations on the macroscopic scale this is why we don't see quantum effects but still doesn't solve what wavefunction collapse really is.
These are unsolved questions.
>>5451970
unfortunately it does appear to be the case as far as we can tell. However as I mentioned previously, every interaction with every particle (cosmic microwave background etc) counts as a weak measurement so collapses the wavefunction a bit (i.e narrows the width of the gaussian spread of the particle's position). So thankfully we have an explaination for why QM isn't visible in the macroscopic world. But that's the best we can do.

No, it "weighs" more when it is moving (has more kinetic energy) which is then lost when it passes through the turbines. Stationary water before and after weigh the same.

>>5456276
I'm assuming that they're referring to the aether that was hypothesized to explain the transmission of light, prior to Einstein's theory of relativity.
Back then people noticed that sound required a medium to travel. The speed of sound was relative to the speed of the medium it was travelling through, if you're inside a supersonic plane, you're still able to hear sounds within that plane, because the speed of sound is relative to the air inside the plane. Light also travelled (i.e. the transmission of light was not instantaneous), so what is it moving relative to? People measured how long it took light to travel a certain distance, but what medium is the speed of light attached to? It's not attached to the Earth, since the sun's light manages to travel through a vacuum. The hypothesis was that it was an invisible, medium through which light moved.
This theory ended after an experiment designed to determine the speed that the earth moved through the aether provided definitive proof that there was no movement.

Most of the things you ask i cannot answer sadly, but i can explain about the interference part and how you can notice something when you cannot see nor interfere with it: You have a mountain with titan in the middle, you cannot touch the mountain but you send a drill to go through it, you notice it goes slower in the middle, but you cannot see what's making it go slower. You cannot remove the mountain it self, and you will never be able to follow what made the drill go slower.
Same with dark matter, there are every different type of interference around it and in this timeline we will probably not be able to remove the interference.
Light interfere differently when it travel through dark matter in a large scale, and the gravitational force from stars can't hold galaxies together.
There have been studies trying to make an isolated area for the chance to notice the dark matter itself.

Actually, it's the inertia anon. Even a proton will resist being moved any faster stronger than all the energy of the entire universe combined could manage against it.
Quite simply, matter becomes impossible to accelerate to c because it's inertia in effect, it's mass becomes infinitely large if you could somehow attempt it.
Note: We do get protons from gold moving pretty fricking close to c in our particle accelerators, just never equal to it. And even that takes metric fucktons of energy to pull off.

The ISS is "constantly falling", but it is falling at such an extreme speed (~8.000 km/s) towards the horizon that the earth curves away from it, leaving it at a roughly constant height.
Interestingly enough: the ISS is low enough to experience some drag and needs small bursts to stay up.
The phenomenon you descricribed as falling faster and faster is what happens when an object is so fast that the earth curves away too fast and the object increases its own altitude.
By increasing its own altitude it increases its own potential energy and reduces its own kinetic energy, and sincr it's mass is constant it reduces it's velocity as it climbs.
However, this climbing doesn't last forever and it will come down after half an orbit, in the second half it will do the opposite of the first half: lose altitude, convert potential energy to kinetic energy, gain velocity.
And since the object increased it's velocity when it reaches the lowest point (which is the starting point) it will be so fast that the entire circle starts over.
