    Grandfather Paradox only works if you are remaining in the exact same timeline. However even in that same timeline you'd be protected if you did kill your grandfather from blinking into nothingness, as you are there and not in the future. Once you returned however no one there will know or have known you it will be as though you never existed to them but you will still be there.

    the only issue with the gameshow paradox is it takes the assumption that the host removes a choice based on what you choose. If the gameshow was always going to remove X even if you picked X than you'd actually be truly 50-50. Pick Z they remove X, Pick Y they remove X or Pick X they remove X. Which in this case assuming that your odds have improved would be wrong. Although I've never seen a gameshow remove the choice you just picked.

      I don't know why you would have an issue with a math problem that has rules. The host knows where the prize is and must reveal a losing one from one of the two you didn't pick. Switching in that case has a 2/3 chance of winning. Without the rules of the host knowing where the prize is and he randomly opens one of the two you didn't pick results in a 1/2 chance of winning by either staying or switching. Because of rules to math problems we are able to determine what the correct results are.

    "Paradox" is Greek: pará means something like "related to yet distinct from" (think paranormal, paralegal, parallel, paraphrase) DOX is teaching or established knowledge, opinion.

    • Klaus 74
      Klaus 74 4 days ago

      Then you don't have a clue of understanding probability. There's a 2/3 chance of picking the door with a goat. The host must reveal one so the probability of him picking a goat is 1. Switching wins when both you and the host pick a door with a goat. So the chances of both of you picking a goat is 2/3x1=2/3.

      The host knows where the prize is and must reveal a losing one. So the chances of winning by switching is the product of the probabilities of both you and the host picking a wrong one, 2/3x1=2/3.

  • Emperor Buttman

    Zeno was right about the tortoise race, he just didn't take his thought experiment to the right conclusion. There are also infinite points between the tip of Achilles' nose and the end of his buttocks so he's one infinity moving through another infinity, same goes for the tortoise. Achilles, the tortoise, and their race track, still have finite size relative to each other, regardless of whether you're multiplying by a factor of 5, 100, or ∞... So even with this premise there is no problem with suggesting Achilles will catch up.
    Interestingly, it is also logically impossible that Achilles will ever touch the tortoise no matter how much closer he gets, which is also physically true given that there is always space in between the smallest particles which make up, say, a block of cheese and a knife, even when the knife is inside the block of cheese.

    in reference to the last given antimony of the Faint young star, would to core of the earth not regulate the temperature just enough to give liquid water? and if so could there not have been both? a layer of ice one the surface but liquid beneath due to the core temperature of the earth? I do know that the core temperature was very different then than it is now, but ti still makes logical sense to me.

  • JJokerMoreau
    JJokerMoreau 5 days ago

    This thing just makes zero damn sense. Adding infinite numbers is impossible (sorry mate). And distance isn't infinite, especially in the tortoise example. Yes, it was never under dispute that there are an INFINITE number of ways to describe the distance between two points, or that there's an infinite number of points between... well. Two points. But that has no relevance on a FINITE distance. Better yet, how can something that is finite, be infinite in the first place? Likely, because there's an infinite number of ways to DESCRIBE the distance, even if the distance is, clearly, finite and set.
    TL;DR - Math playing some semantics here yo.

    Monty Hall still doesn't make sense to me. Either way you can only walk away with one envelope which would truly give you a 50% chance of picking the right one out of the 2 thats left

    • Klaus 74
      Klaus 74 5 days ago

      Switching wins when both you and the host pick a wrong envelope. The chances of you picking one is 2/3 and for the host it's 1. So the chances of winning by switching is 2/3x1=2/3. If you picked envelope 1 and the prize is in 3 he reveals 2. If the prize is in 2 he reveals 3. So you win by switching if the prize is in either 2 or 3.

    If time travel to the past is possible, would it require all particles and waves in the universe to reverse their trajectory or just the local area where time is being reversed? If its the latter, how would we account for any particles that have traveled beyond the field of influence that would have interacted with the objects during its time period.

  • BKnight7z
    BKnight7z 8 days ago

    i dont really see how it makes a difference though because effectively the 2nd choice is being made whether you switch or decide to keep. it isnt only being made if you decide to switch it. if the two remaining had an equal chance at the beginning anyway how is the swap relevant at all? this idea makes sense because if having chose the opposite of the final two originally you would be in the same exact situation regardless of which way you believe already logically.

    • BKnight7z
      BKnight7z 8 days ago

      Klaus 74 you don’t seem to understand what I’m saying. The choice is still in effect and doesn’t make a difference if you actually switch or not. You’re still making the decision. Just because one envelope is now guarenteed wrong from the other two doesn’t mean that it is guarenteed to have a correct pairing also. And just because the envelope you switch your original choice with from that group of two is from that group doesn’t make it any more relevant to the odds making of this entire event. Rather the 66% becomes immediately irrelevant as soon as the loser is opened and doesn’t become relevant until retroactively the winner is revealed. Yes at that point the winner could have been from the 66% group or not but in making that decision it didn’t matter if you switched or not because you still made that “50%” decision when it was presented. You should always make the decision not always make the switch is what I’m saying

    • Klaus 74
      Klaus 74 8 days ago

      You seem very confused. With a 2/3 chance of picking a wrong envelope then there is a 2/3 chance the revealed one is the second one. So there's a 2/3 chance of winning by switching. With a 1/3 chance of picking the correct envelope then there is a 1/3 chance the revealed envelope is the first wrong one. So there's a 1/3 chance that the second wrong one is available to switch with.

    • BKnight7z
      BKnight7z 8 days ago

      i.e. the problem being that the probability is relative to you the chooser but it cannot also be applied equally to the envelopes at each step themselves as they have no stake in the equation. from my perspective this paradox seems to do this and thus i think it may not be as valid as everyone thinks. essentially the concept needs a "chooser" to be validated therefore it is not conceptual in nature

  • BKnight7z
    BKnight7z 8 days ago

    what he should have said is effecitvely you are getting retroactively the decision to choose and be given 2 options at the beginning choice and having those 2 face off as a pair towards the one additional choice.

    • Klaus 74
      Klaus 74 7 days ago

      If you pick envelope #1 and the prize is in #2, he will reveal #3. And if the prize is in #3 he will reveal #2. So you will win by switching if the prize is in EITHER #2 or #3 and you can only win by staying if the prize is in #1.

      The turtle created a paradox for Achilles alone and not us as readers of the story. Achilles wasn't nearly as smart as the turtle and was fooled by his shelled friend into believing he wouldn't catch up with him, given that he would have a slight head start. So he then refused to race him even though he originally asked for one.

    My paradox:
    Let's say two people are in an argument. Person A and Person B.
    Person A claims: There is no such thing as a false opinion
    Person B claims: There is such thing as a false opinion
    Both people are arguing over which one is correct.
    Person A says there is no such thing as a false opinion (which counters Person B's opinion), so they're technically stating their opinion, which seems false to the other person because in an argument there are (typically) two opposite sides.
    So person A is saying that there is no such thing as a false opinion, but [Person B's] opinion is false based on [Person A's] view.

      They each spent 9 cents for a total of 27 cents. 2 went for a tip and 25 went for the beer. You subtract the 2 from the 27 to account for the price of the beer, and not add the 2 to the 27.
