In conclusion, the question of whether something is more or less impossible/necessary amounts to a question of pragmatic: how much does it cost to change a definition or a feature attached to a concept? So we take for granted that there is 1 perceptible universe and in order to describe that we'd like to be able to build a logically consistent model for which we are looking for suitable axioms. Re your first sentence: The criterion for truth is the same in mathematics as it is in physics as it is in any other discipline, namely that the statement "X is true" is equivalent to the statement X. There is no "safe" theory, impossible to be disproven, thus, you cannot say something is impossible. Simon Pegg has called time on the nerdy stuff, and says he'd rather watch Succession than sci-fi. Still others are a manifestation of a voodoo curse or perhaps a parasitic fungal infection. Zombies from 1968's "The Night of the Living Dead" were actually called ghouls, but they definitely exhibited many of the virtues of what we consider zombies. If it is then you lose any basis for saying something is impossible. The genius of Bem's work was to change the order of this sequence. Can something be within the limits of ability/power/opportunity yet also create a contradiction if it occurred? Use MathJax to format equations. This is always truth. For it to exist is to deny its logical impossibility. And seeing as how they're zombies, that's probably a good thing. Like if you had no idea of how it works then describing an infection as being possessed by demons and a doctor as being a high priest of an arcane religion performing rituals on the possessed is not actually that far off the truth if you think about it. It's just extremely unlikely. The best answers are voted up and rise to the top, Not the answer you're looking for? @jinawee: I think what he meant to say was that that it is possible, in Peano arithmetic, to formulate true statements about the natural numbers that are not theorems. Spooky! Top 10 Unexplained Phenomena | Live Science This resulted in some clear definitions of axioms set like Peano, ZF or ZFC, which are proved (or strongly believed) to be consistent, i.e do not allow to demonstrate both a theorem and its negation. What is impossible? | plus.maths.org NBC News. They close every time. Different reality may be has its own logical explanation. People who eat large meals regularly may stretch that capacity to some degree. A ball of uranium 1km in diameter. Bridgeman is an operationalist: he thinks theoretical terms reduce to measurement operations, while conventionalists think they are conventions for interacting efficiently with reality. The motor runs forever. How Did Old Testament Prophets "Earn Their Bread"? That is because logic requires apriori knowledge in the form of atleast one logical set of premise. So the general concept of having these wild ideas is not out of the ordinary and at times has been quite successful. @Niel de beaudrap - Fair enough. If not observing them cannot disprove them, then a theory without them works as well in predicting the future. Yet it wasn't until the 1800s that we finally figured out that the tiniest of invaders, such as smallpox or HIV, are often the most dangerous of our biological enemies. It is like saying something is impossible because you did not observe it. . So it seems logical you cant go below it. But you can jump beneath it. So TL;DR what you end up with is that things that are logically impossible being physically possible, because the logic system might have been build on insufficient data. :(. On the other hand "physically impossible" things are only impossible as far as we understand physics, which will never be perfect. "These theories are correct when they are correct"? Well, let's look at some examples of how this is impossible, using the Bible as our reference point. mathematics - What is fundamentally physically impossible? - Physics "Zombies: The Facts that Keep Alive the Story of the Undead." NPR. b : extremely awkward or difficult to deal with the actor was impossible on the set. High heat and humidity speed the deterioration of rotting flesh by providing perfect conditions for the proliferation of insects and bacteria, which decompose anything they set their enzymes to. (June 1, 2015) http://io9.com/a-history-of-zombies-in-america-5692719, Pappas, Stephanie. If Quine's arguments are sounds, there is some continuum between what is true in virtue of linguistic conventions (logic, generic scientific principles maybe) and what is true in virtue of the world (direct observations) with scientific laws in the middle. "8 Historically Terrifying Viruses." Evaporation from carbon nitride cools that plate. Above 0 kelvin, spontaneous cold cathode emission runs the closed isolated system. Like so many others, I wonder how long I'd last in this kind of end-world scenario. Im just wondering whod want to tickle themselves. 10. So for now it's physically impossible. Physicists have long suspected that neutrinos could fall in this category, although proving that means spotting some of the rarest process in the universe in action, that happen perhaps once in 100 trillion trillion years. How about: P-Zombies Souls It's logically possible, but not metaphysically possible, that I had different parents (if you believe Kripke) That water is not H2O is logically, but not metaphysically possible. "How a Zombie Outbreak Could Happen in Real Life." I sneeze with my eyes open almost all the time when i try to hold it in. This is a very debatable assertion and I would say it is false. However, the point is that there are some people who do believe in those things, notwithstanding the fact that they appear utter nonsense to me, and some (philosophers particularly) who like debate the possible existence of such things given that they cannot be disproved. Absolute truth is what philosophy wants but never reaches. I did not downvote you. I am just referring to the rejection of contradictions. Do symmetries indicate that laws of physics are invariant? (I think this is also a modern physics approach.) Suffice it to say that zombies are not likely to join Weight Watchers anytime soon. How low? The art of cold reading can appear to be paranormal. These are soeasy. Because we are the one who made the definitions, we can perfectly understand the rules at play and how they are broken. Now, curl your middle finger under and try to raise your ring finger. Something is logically impossible if. Technically yes. Assuming angels exist, people who angels have appeared to can confirm they exist, but people who had no angelic visitations have no chance at proving or disproving it. Again, technological possibility is a subset of physical possibility. rev2023.7.5.43524. 1a : incapable of being or of occurring. Something can't be actually possible yet logically impossible. For instance, why does Croatia feel so safe? Such states arent practically very useful. Although I think at this point in time, it's accepted that brain-in-a-vat and magical fairies and so forth are almost certainly not true, and no mechanisms exist that would allow us to investigate such claims. And therein lies the difference between physical and logical improbabilities. In theory, zombies consume brains because they, too, require sustenance that perpetuates their ability to function. Unless you were doing it wrong, 1 is easy, 6 I canbackflip on the spot witch I jump almost 34 of my height, 4 tickled the roof of my mouth, 10 I only tryed 4 so that's not half, so most of these "impossible" facts are bull sh#t haha. IMO, there is nothing fundamentally physically impossible. Certainly, one of the things that is absolutely impossible for any of us (living creatures) who belong to the human family, to do is to survive for any substantial period of time without the essentials. I think it's the body's way of preventing your eyeballs from blasting out of their sockets. However, it does not concern him, since it is a singular occurrence, and physics is about the possibility of recreating results in reality. Philosophy Stack Exchange is a question and answer site for those interested in the study of the fundamental nature of knowledge, reality, and existence. The nutrients that humans consume begin to break down the moment we start chewing up a slice of pizza or quiche. In other words, if a physicist threw 100 stones in an experiment, and a deity would steal one from him, or displace, but the overall results would follow theory within the required statistical rigor, he would be happy with his theory. Which sparks creative solutions but is ultimately impractical so after a brainstorming period you'd set out to actually define terminology and codify ideas so that it once again approaches the attempt at a logic system. Viruses, fungi, bacteria and other microscopic invaders have plagued humankind since the beginning of time, shortening our lifespans and often make our lives miserable. Something fundamentally impossible, would be something impossible to observe. And you cant just simultaneously say the probability is low and then say the number and range is irrelevant. But even if there were, we still shouldn't be completely certain that it's impossible, because evidence, or our perception of evidence, can be flawed. Copyright HarperCollins Publishers It seems an error to bring in physics. The best answers are voted up and rise to the top, Not the answer you're looking for? I'll add some comment about it. Zombies have been a fixture of folklore and creative media for hundreds of years, but they've really sprung (or lumbered, if you prefer) into the limelight in the past decade or so. (June 1, 2015) http://www.nytimes.com/2013/06/23/magazine/max-brooks-is-not-kidding-about-the-zombie-apocalypse.html?_r=0, Castro, Joseph. I'll first discuss the difference between truth in Physics and Mathematics. | Meaning, pronunciation, translations and examples @PeterJ: The question itself was a misunderstanding, in my opinion, and I was merely attempting to answer it on its own terms. (Or that is the proposal here). 28 June 2015. There will be no logical structure if there is no reality. Revival If // Dr. Rod Parsley Dominion Camp Meeting 2023 | meeting Because zombies aren't known for their fully functioning bodies, they may very well have gaps in their digestive system somewhere between their mouths and anuses. In fact, teleporters already exist: not for whole human beings, but for subatomic particles. The guy has X-Ray vision. For a statements like "mass of a particle can't change" (or whatever your impossible-candidate is) must necessarily be statements made by humans and hence underlie a theory (e.g.
