The part we can perceive? That is called the observable universe, which is entailed by "c " and the time that the EMR has had to reach us within the known age of the universe and the expansion rate. That's nice....as a lay person myself, I re-enforce my knowledge by reading reputable books, then through forums such as this, if there is something I don't understand, I ask questions. The general picture of the evolution of space/time/universe is a model that to me anyway, makes a lot of sense. Prior to t+10-45 seconds, where the BB and laws of physics does fail us, I also have my own hand waving ideas...I speculate that the BB is actualy the arse end of a BH, which we call a White Hole. but you also said, Science creates models that match observational data and tells us what is happening. The why it is happening is another aspect. There is a great little video [only 7 minutes long] that explains what I mean by Richard Feynman. I have linked to it many times, but I also believe it is informative and tells us the role of science....https://www.youtube.com/watch?v=Q1lL-hXO27Q The other point I would make is like you, I am relatively mathematically ignorant, and maths being the language of physics, leaves people like you and me, behind the eight ball somewhat. I hope you take the 7.5 minutes to watch the video...quite impressive by an impressive scientist. In conclusion I would just remind you that while GR is our most accurate model of gravity, it does not [as some people often say] determine that Newtonian gravity is wrong. Newtonian gravity is simply a less accurate model, but accurate enough for us to use every day on Earth, and accurate enough to be the model used in most space endeavours. We could if we wanted to use the more accurate GR, but it does entail much more mathematical equations, to give us the same answer, [but with more accurate results] and is not really needed. Join the club!! I'm an old bastard, but still hope I'm around to eventually see boots on Mars....at least!!😉

I don't know well how cryptocoins work. It is said they spend so much energy as an entire country. The question is who pays such energy?

I think people don't count correctly costs and energy consumption, because they concentrate just on CC side. The real existing paper money requires: ATM (millions of them!), terminals, delivery from/to banks/shops/offices/homes (delay), guards delivering money from ATM to/from banks (wages, fuel, equipment etc), additional security and staff in banks/shops/offices, printing and replacing damaged units from time to time, money safes and money counters in banks/offices/shops/homes, hard to measure cost of delay in transaction due to physical existence (e.g. consumer has to drive for money to ATM and return back).. etc. etc. Multiply by the all people on the world using physical money and I bet it will consume more energy than CC. Paper money must be recreated when it is too much damaged. It happens every couple months or years. Unlike coins, raw material can't be reused, so yours $0.05 per unit, is underestimated IMO.

Only if you redefine the word to eliminate one of its common usages.

If you have some time, please visit commercial link removed by moderator, and let me know what you think. You may be pleasantly surprised. Thank you.

You cannot say a wave is alive. A wave is just a change in voltage. For instance a square wave. The consciousness "could" arise from a waveform, but we simply do not know enough about voltage and consciousness to test if it even exist. If you are saying a waveform is alive then a computer is alive, and any electrical appliances carrying a voltage is alive, which I sort of rule out because the possibility seems low or I would not know. The only way to test this is not from something that does not exist but from actual evidence that we can learn from, for instance, human, or any organism exhibiting a consciousness for that matter. It seems you are implying that the consciousness arises out of voltage resonance(this might not be a term but I used it for clarification), or electrical resonance, but a resonance is just a change in amplitude, I can have a resonance on 5 volts or I can have a resonance on 5000 volts, the implication to which the consciousness arise from this phenomenon is not well defined.

Then what do you want me to do @@?

But even with a high voltage gain on RC resonance does not equal consciousness right? Or are you saying there is infinite voltage in the brain at the resonance point?

Ya, that is cool. So what defines one person's consciousness from another? The voltage voltz level?
