Hm... I want to reply to this but I didn't have the time to break this down. I'll quickly say that yes, there is finite energy even if it might as well be infinite, taking power for ourselves is taking power from something else (be it from nature or from the yehuborim as they did us). We may as well consider us taking power from each other if our intentions aren't perfectly aligned, though expectedly this misalignment would be mostly negligible. Your way of expanding thought is useful up to a certain point, but I've gotten into the habit of simplification. I just don't have time to write an essay I can't even guarantee won't get nuked by some mod about something self explanatory.
It's fine. I'm going to add more!
I'm also considering "exotic particles" which appear to appear out of nowhere. If there is a limited amount of Energy, an absolute limit, then once Earth and Her Inhabitants fix the Earth again, and then everyone becomes immortal, and then we continue to have Children and generations
ad (nearly)
infinitum (if you will), then there will be a definite point where... Star Trek again... everyone is at maximum and in an over-the-top idiot way as depicted in one episode, everyone is literally squashed together due to overbreeding and no more room - in real terms, what I mean is we'd 'consume' all of the Energy, eventually, and then we'd not be able to advance any further. It's been said that Spiritual advancement is unending, is eternal. These are literal terms, not metaphorical nor symbolic.
To make it easier to understand - take a large building, which represents all of the definitely-limited, finite Energies in total. No-one can escape the boundaries of it, but people keep growing and having Children in there, taking up space and making furniture and sculptures and consuming resources (Energy). Even if birth control is done, we'd still consume Energies as a Natural part of our existence, as standard process. After X time, the maximum of the building would be reached, and if we're immortal in the very large building, we'd, in one way or another, suffocate. Unless it is like a sealed terrarium where everything is recycled and nothing new happens - but which still needs outside input from the Sun for warmth and Energies. There was a Man who had a terrarium and after the last time of watering it, he never watered it again because the water and nutrients were recycled internally. In 1960, David Latimer used a terrarium and watered it once in 1972, then sealed it, and it continued to thrive. Of course, the plants still needed outside input - the Sun for warmth and Energies and photosynthesis. If the entire Universe has a limit, then without any input from "outside the Universe" to keep sustaining us, then we'd consume all things and die. Unless perhaps we'd somehow follow the Kardashev scale and become as traditionally-though-of Gods and Goddeses "outside the Universe" and [insert current creationist "god" examples here].
Unless there are some things I'm missing. I try to consider enough things, of course!
