Neil deGrasse Tyson Says It's 'Very Likely' The Universe Is A Simulation (extremetech.com)

mspohr quotes a report from ExtremeTech: At the most recent Isaac Asimov Memorial Debate, [scientists gathered to address the question for the year: Is the universe a computer simulation? At the debate, host and celebrity astronomer Neil deGrasse Tyson argued that the probability is that we live in a computer simulation.] This is the crux of Tyson's point: if we take it as read that it is, in principle, possible to simulate a universe in some way, at some point in the future, then we have to assume that on an infinite timeline some species, somewhere, will simulate the universe. And if the universe will be perfectly, or near-perfectly, simulated at some point, then we have to examine the possibility that we live inside such a universe. And, on a truly infinite timeline, we might expect an almost infinite number of simulations to arise from an almost infinite number or civilizations -- and indeed, a sophisticated-enough simulation might be able to let its simulated denizens themselves run universal simulations, and at that point all bets are officially off."

      >If you're inside a simulation, then you can't run any tests to find out, now can you?

      Why not. There are certain characteristics a simulated universe is likely to have - you can test for their presence. And quite a few of them are present in our universe. What we haven't figured out how to do is prove that a real universe wouldn't have the same characteristics.

      It's definitely a testable hypotheses. The fact that we don't know exactly HOW to do do the test yet doesn't mean it can't be tested. The mechanics of testing have nothing to do with the definition of testable. When Einstein predicted gravitational lensing we had no idea how we may test that - after all, how can you tell if the light you're looking at has been bent by gravity in the past ? Nothing on earth has enough gravity to bend light enough to measure with 1901 technology. We figured it out some ten years later - we can look at an eclipse from Jupiter which is just far enough that light is measurably delayed, and that means if there's gravitational lensing the delay should be slightly different than if the light had travelled straight. The test was done and confirmed the hypotheses* - but it was testable when first announced.
      Testable meant: "If you can show that light has bent in the presence of gravity, you can test the theory" it didn't have to mean "and here is how you determine that". It's perfectly fine to leave the HOW of testing to the reader, or future scientists who will have access to technology you don't have.

      If anything this is more testable than a lot of theoretical physics. We still have no idea how to test any of the variants of string theory. We can show they are logically consistent and the maths work - but much of it we have no idea how to test.
      Dark matter when first proposed seemed to fall clearly in the "untestable" category - how do you know something is there that doesn't interact with anything, doesn't give of any energy and cannot apparently be found ? Many scientists declared it "theory saving". Eventually though, somebody realized that if dark matter exists and has mass (and it has to have mass because it was proposed as an answer for missing mass in the first place) - then it would bend light (as per the aforementioned gravitational lensing) - and we've observed that - light being bent by a gravity source where no objects can be detected.... so it must be getting bent by objects we can not detect.

      *Ironically that test was terribly flawed, and later entirely discredited, but other more accurate tests subsequently done did confirm the hypotheses again. That too is part of science, sometimes the wrong tests can give the right answers. This is one reason we retest things and re-examine old data and old experiments. Because the test was flawed, it could have been that the hypotheses had been wrong all along, retesting with more advanced technology and avoiding the mistakes made last time would let us find out if that had been the case.

Some species have been shown to be able to detect ultraviolet light and most cave-dwelling species have developed the ability to utilize very dim light. They also have high-quality senses of smell and hearing. Bats hunt at night, reducing competition with birds, minimizing contact with certain predators, and travel large distances (up to 800 km) in their search for food.[3]

      Megabat species often have excellent eyesight as good as, if not better than, human vision. This eyesight is, unlike its microbat relations, adapted to both night and daylight vision and enables the bat to have some colour vision whereas the microbat sees in blurred shades of grey.

      It's definitely a testable hypotheses. The fact that we don't know exactly HOW to do do the test yet doesn't mean it can't be tested. The mechanics of testing have nothing to do with the definition of testable. When Einstein predicted gravitational lensing we had no idea how we may test that - after all, how can you tell if the light you're looking at has been bent by gravity in the past ? Nothing on earth has enough gravity to bend light enough to measure with 1901 technology. We figured it out some ten years later - we can look at an eclipse from Jupiter which is just far enough that light is measurably delayed, and that means if there's gravitational lensing the delay should be slightly different than if the light had travelled straight. The test was done and confirmed the hypotheses* - but it was testable when first announced. Testable meant: "If you can show that light has bent in the presence of gravity, you can test the theory" it didn't have to mean "and here is how you determine that". It's perfectly fine to leave the HOW of testing to the reader, or future scientists who will have access to technology you don't have.

      If anything this is more testable than a lot of theoretical physics. We still have no idea how to test any of the variants of string theory. We can show they are logically consistent and the maths work - but much of it we have no idea how to test. Dark matter when first proposed seemed to fall clearly in the "untestable" category - how do you know something is there that doesn't interact with anything, doesn't give of any energy and cannot apparently be found ? Many scientists declared it "theory saving". Eventually though, somebody realized that if dark matter exists and has mass (and it has to have mass because it was proposed as an answer for missing mass in the first place) - then it would bend light (as per the aforementioned gravitational lensing) - and we've observed that - light being bent by a gravity source where no objects can be detected.... so it must be getting bent by objects we can not detect.

      *Ironically that test was terribly flawed, and later entirely discredited, but other more accurate tests subsequently done did confirm the hypotheses again. That too is part of science, sometimes the wrong tests can give the right answers. This is one reason we retest things and re-examine old data and old experiments. Because the test was flawed, it could have been that the hypotheses had been wrong all along, retesting with more advanced technology and avoiding the mistakes made last time would let us find out if that had been the case.

      This is one of those "proving a negative" things.

      Wrong. You clearly don't even understand what Bostrom means by "posthuman", or you wouldn't make such a ridiculous objection.

      I already explained my position. The assertion of point 1) is completely irrelevant. And Bostrom's idea of "posthuman" is just not that relevant either. I think I have a pretty good idea that someone who can make Dyson spheres merely for computation (which incidentally is a rather strong assumption about the physics of said world simulating us, don't you think?) is not just a Cheetos-stained code monkey with a bigger computer.

      This also conflates probabilities of events inside our universe with things that are not in our universe. It's another not even wrong thing.

      Your objections about inside/outside are complete nonsense.

      I already gave my argument. Think about it this time instead of making monkey noises. My statement which you quote is fact. This is exactly what Bostrum did. And thus, he conflates something which is knowable with something which is not. Not even wrong.

      And third, note that the author conflates "ancestor simulations" with "living in a simulation".

      There is no difference.

      I already explained why your rebuttal is wrong. One can simulate physics that is radically different than whatever their ancestors experienced and hence, is a simulation which is not an ancestor simulation. Come on, you have a brain. Use it rather than wasting my time with this unthinking crap.

      It seems, heh, "likely" that anything with the computing power to simulate ancestors would also have the computing power to simulate alien universes with alien physics and alien lifeforms.

      Yes, and your point is? The point of the proof was to argue how likely it is that we, in our universe, are a simulation. Alien universe simulations aren't relevant.

      My point is that this is another example of why the overall argument is terrible. For example, going back to that notorious argument 1), it means that we might be in a universe simulation with radically different difficulties for being posthuman than the universe which simulated us. This once again illustrates the huge flaw with conflating probabilities inside our universe with probabilities outside our universe.

      Also this quote of mine outlines a simulation which is not an ancestor simulation and happened to address your prior concern.

      Further, how many times are we being simulated? For all we know, there may be an infinite number of current overlapping simulations of our reality or the simulation(s) might have stopped eons ago and we aren't currently being simulated.

It is only if you assume physicalism as ground truth, yet there is no valid scientific reason to do so. In fact, there are a number of unsolved problems with physicalism.

    Note that I do not see the variant where religion has hijacked dualism as an alternative: That is a pure result of human shortcomings. Dualism does not need religious ideas in any way. But assuming physicalism is true is not science, but belief, and as such a fundamentally religious thing to do. The current scientific state of the dualism vs. physicalism problem is simple "we do not know", with some indicators pointing to dualism, but nothing solid.

The other point is that if you were to believe in the universe-as-simulation crap, you'd have to also allow the possibility of an infinite regress of the aliens deceiving us also being in a simulation, the robots deceiving teh aliens deceiving us also being deceived by Decartes Evil Daemon and the Evil Daemon deceiving the robots deceiving the aliens deceiving us are in turn deceived by the turtles. The turtles told me this, and that after them, it's turtles all the way down.

  158. It's the Boltzmann Brains argument, but different. by RockDoctor · · Score: 1
    From Wikipedia:

    A Boltzmann brain is a hypothesized self aware entity which arises due to random fluctuations out of a state of chaos.

    It's another variant of the problem of infinite universes or multiverses - if it can happen, it will. And once it has happened then the likelihood of anything "interesting" (define "interesting") happening spontaneously is lower than of the same event being simulated (or, arguably, stimulated) by the "brain".

    Like panspermia, it's a not-impossibility, but it's also a dead end of an argument. Like "goddidit."

  159. 5700 years ago, this simulation was started by Keybounce · · Score: 1

    Approximately 5700 years ago, God started a simulation of the universe. Why?

    We can only guess. Perhaps someone asked a question, that was so complex that the only way to determine the answer was to simulate the universe, and determine the answer. Given the huge cost and difficulty that this has resulted in, God has now decided that "Seer of Mind" is just too expensive of an ability, and there will be no more "blind justice seekers" into the future. But the existing "justice is blind" seekers have demonstrated just how crazy the view is.

    When the answer is determined, the Seer of mind will know the result of the choice, and will then know whether or not to kill her opponent. Later, someone will retcon the choice and the whole "put down your arms and don't fight" will turn out to be the better choice. Hence the whole "be kind to each other" that is preached and ignored in this simulation -- the truth tries to show itself.

    Is the universe a simulation? Is the universe a hologram? Is reality real? Are there uncountable numbers of universes?
    Quantum physics is very expensive to calculate and ultimately a simulation requires more energy then the equivalent real universe. Tricks like lazy computation don't work.

    People only come up with crazy ideas like these because general relativity is crazy and poisons the rest of the physics 'system'. If 'pure' general relativity is correct then the universe cannot exist making simulation type arguments much stronger. 'Impure' general relativity includes an absolute FTL frame, which means it contains elements which directly contradict each other.. FTL physics is a real mess.. :)

    Two things:

    1) "simulation might be able to let its simulated denizens themselves run universal simulations", or turtles all the way down etc... Is basically saying that given a really large number (infinite by definition being the largest) it is unlikely (read improbable) that we are either the first or last turtle. Which from a purely conceptual point of view is true, but in reality much like a lottery, while it might be very unlikely to win, someone actually does, meaning that in real terms someone is the turtle or the simulation maker, the first the last, and all things being equal, just because it is a very low probability, doesn't make it untrue.

    2) When talking about perfect simulations, and simulations making simulations, the Matrix did it right (though they probably borrowed it from someplace), in that at a certain point the difference between what is reality and what is a "simulation" grows fuzzy and may be a moot point. It all gets rather philosophical at a certain point, the whole I think therefore I am, and if a tree falls in the forest sort of idea, but basically even if a simulation that doesn't necessarily mean in the strictest sense that it is any less real...

However that human brain may well need the quantum nature of the universe in order to operate so you do need to simulate its nature.

    However the most completely unbelievable part of this utterly preposterous argument is that it assumes that the simulation has no bugs. Not once is the potential for a bug in the simulation code ever discussed. The chances of such a massive program have no bugs is incredibly small. The only exception would of course be if whoever created the simulation was infallible...at which point the creator of the simulation really starts to sound exactly like god.
