  1. When is the state of a system not changing in regards to the system being defined as the universe? I had to Google "For thermodynamics, a thermodynamic state of a system is its condition at a specific time, that is fully identified by values of a suitable set of parameters known as state variables, state parameters or thermodynamic variables." Is anything actually in a steady state for more duration than our measuring tool? Can there be the same system conditions with different variable values? If so how could we differentiate between steady state and not?
  2. How does this effect the practical limitations of us generating the maximum possible temperature? (As I see it #2 was the current limiting factor). Are we in steady state or close to it? (What's steady state)? What's the maximun KE? How is spin involved? Why does a population inversion give a negative temperature? (Doesn't that make you question the validity of the theory(asked without me understanding "steady state")?
  3. Oh how does that work? To clarify; I mean if, "the universe is a simulation", not, "if we were to simulate a universe". I actually didn't use the word simulation on purpose because it conveys a sense of incompleteness. Perhaps to rephrase, if we had a processor which ran at the speed of light, could we simulate a part of the universe in real time. Ego predict the weather with 100% accuracy. Or everything in our galaxy?
  4. I Googled and looked at the wiki, it's called "absolute hot" apparently. There's 3 main definitions there. 1. The Planck temperature, which has the value 1.416785(71)×1032 kelvin. (Which is what I was getting at I think) and is at a limit due to no theory of quantum gravity apparently. 2. The Hagedorn temperature. Where particle pair formation draws heat away from the area being heated, limiting it. As I understood it. 3."Quantum physics formally assumes infinitely positive or negative temperatures in descriptions of spin system undergoing population inversion from the ground stat
  5. I assume the hottest temperature the universe has ever contained was at the moment of the big bang. Is this possible to achieve again or beat in the current universe or would it be prevented by entropy? What is our best estimate of the hottest possible temperature?
  6. Could the speed of light be said to be equivalent to the processor speed?
  7. Wouldn't the minimum measurable interval of time and space, the Planck length/time , be considered the unit of time and of space? I know a unit isn't exactly a particle. However a photon is and it is our interactions with a photons properties that give these units. Therefore if photons are deemed to be real, by induction time and length should also be real.
  8. Is it possible to have more than one flu at once, or more than one cold, or a cold and a flu at the same time? The reason I ask is because I came back from traveling recently with what I think is a cold ( although I don't recall ever having a flu in my life). Shortly after, (3 days), my 3 flatmates all got sick with the "flu", and one reckons his daughter previously had one, the other says his mate did. One of them went to the doctor and he said it's the flu. I'm also wondering if "man flu" is real. How does a GP know, apart from the level of complaining? Am I safe or should I
  9. Yes and there are vastly more scenarios. Could anyone do an example of all the possible outcomes for a small set of people, as in 10 which I started above. There's some mistakes in my examples above. The 6 outcomes are. 1. Everyone kills a partner or forms a circle and kills simultaneously = 0 alive. 2. Everyone lines up single file 10*1 and shoots the person in front = 1 alive 3. They pair up and as above 5*2 = 2 alive 4. There's 3 rows of 3 and 1 single 3*3+1 = 3 alive 5. Two rows of 4 and one of 2, 2*4+2 = 4 alive 6. Two rows of 5, 2*5 = 5 alive. It seems to me the answer l
  10. As was shown in your sequential killing chain all that is needed is for someone to kill another who has already killed for the end population to be less than 50%. You can either kill a killer or a non-killer. The two extreme possibilities as I said in the OP are: 1) Half the population kill one other person who has not yet killed another. Result = 50% (minus 1 for odd numbered population) 2) The entire population kills another simultaneously. Be it lining up in pairs or in a circle, or any other crazy pattern. So you could imagine with n=10, all could from a line single file,
  11. Of course there's time. The rule is that: everyone who is alive must kill only one other person or die in the process without killing anyone. In your 10 people problem time solves the conundrum, by use of the term "then". ie 9 kills 10 then 8 kills 9. But there's as many permutations, ie 10 kills 1 then 5 kills 10, or 2 and 3 kill 4 and 5 and 4 and 5 kill no one etc (or is there? are the permutations restricted?). In a n=10 population what is the most frequent number of survivors?
  12. A friend and I were recently watching "The Purge", and the topic came up that if everyone in the world killed only 1 person that the world's population would be halved. I thought about this for a minute and realised mostly it would be reduced by more than half and that in the extreme people pairing off and simultaneously killing each other could reduce it to 0, while still fulfilling the criteria. My question is what would a probability distribution of this scenario look like. What would be the most likely percentage remaining alive? What is this kind of maths problem called? Edit
  13. No one has to do anything. That doesn't mean there isn't a right and wrong.
  14. I want to point out that I'm not saying this universe is a simulation as that would most likely be unfalsifiable. However I found this in wiki... so maybe not: I just want to know if infinite simulations are possible. Sensei, does my question of your partial simulated universes, prevent an infinite number of simulations, or am I overlooking something? You suggest our universe is already a simplified one, but could the way our universe currently work be simplified further and would this enable an infinite amount of nested simulations? Or does this mean that nested simulations need
  15. And these kind of simulated universes could be simulated infinitely within one another? At one point wouldn't the simulator not have enough information to gather from their surroundings to provide a simulation which works? I mean if there were 1 million rules that govern a universe and the first simulation cut that in half to 500,000 rules, so not simulating parts unseen, wouldn't at some point there not be enough rules for there to be a being that could continue the process? This is interesting, from wiki:
