    "The problem is that we don't know what the laws of physics are " Thank you Sir. This is the issue with science being projected and accepted as facts amongst society in relation to all aspects of life. We know what's available to us and the rest is pure speculation based on our understanding of what already exists. We merely observe and interpret creation as we are not in control

      And yet to didn't errors in his reasoning.
      Science relies on the fixed laws of physics to explain natural phenomena, ... and is limited to things of our Universe.
      We do not know all the Laws of Physics, but what we do know clearly supports the Universe & Life being unnaturally made by an intelligence.
      Matter, energy, space, time and the Laws of physics are Functions, with set purpose & rules, and will PROCESSES inputs into outputs.
      A Function(Process) can be abstract (time, space, laws of physics) or concrete( matter, energy).
      And all Functions are unnaturally made by an intelligence. There is no evidence proving Natural processes under the fixed laws of physics can make a quantum particle, electron, neutron, proton, atom, element, compound, molecule ... life, planet, star ... or laws of physics.
      The Laws of physics are prescriptive ... according to what the Function maker has determined.
      There are no other worlds or Universes ... without a Function Maker/Creator.

      Agreed, this was a exceptionally thought provoking conversation. I've never heard the question of physical laws framed in quite those terms at 5:00. Dr. Kuhn took notice of that conceptual leap, and he has heard many takes on the subject. The concept of platonic possibility space, for me, brings to mind a line from the bible... "In the beginning was the Word". I am no theist, but wouldn't god be included in "possibility space", or be the possibility space itself? This seems self evident.

    I can’t help but think of possibility spaces in the context of the anthropic principle that all of our possibilities lie within an apparently brief and unique period as viewed from what we believe to be true on a cosmological timescale. And secondly, what might yet be for our posterity’s possibility spaces during the time that remains if the consciousness evolved on planet earth survives.

  • @jacobbaird951
    @jacobbaird951 Před 2 lety

    When we populate possibility spaces, how do we draw the line between "possible" and "impossible"? If I were to think of the possibility space of my location 5 minutes from now, it might include my basement, my living room, on the street, and so on, but for each of those scenarios some precondition would need to be in place, such as "I had to turn on the dryer," "I wanted to watch TV," "I saw my mail lying in tge street," which themselves form a possibility space descibing where I might be some time before 5 minutes from now. I can repeat this process back to my current state, but of the possibility space of my current state, only one can be truly possibile, and that is the reality that I'm now observing. If we live in a causal universe where every cause has a definite effrct, I don't see how we can talk about some states which are "possibile" and some which are "impossible." We might say a state "might be possible" because we just lack omniscience and don't know the complete state of reality at any given time, but the more we uncover, the narrower our set gets. The interviewee said something to this effect in the video about the rationality of pi, but went on to say there is a real possibility space, the scale of which dwarfs our observed reality. So, to me this concept presupposes non-causal, chance outcomes.

    Spot on! The thought of multiple possibilities are real but some of those possibilities aren't possible as coming to existence. For instance there's a multitude beliefs systems and as a thought all of them are real although they don't compliance with those space possibilities that in the end of the day can came into existence. Most of all because epistemological reasons than ontological ones.

    Interesting discussion! But either prescriptive or descriptive law of physics can only solve half of the problem. Assuming the law of physics is true (including the probability theory), the set of events (E) that you experience in your life must follow the conditional probability rule. Giving condition A (law of physics), the probability of the world we know (set of events in your life) is P(E|A). But there is another pre-condition in the equation: Giving condition B (human brain and perceptions), the probability of "condition A" is p(A|B). Now the real question is: Are condition A and condition B independent? All scientist suddenly become philosopher :D lol

    Am no overseer, nor would I want to be although philosophy digresses in all avenues to a certain degree, the lack of reverence for Philosophy & metaphysics & theology today is a direction I will not be part of.
    Philosopher is the most revered Appalachian and position of the utmost straneous work to achieve, and today although its true essence seems lost, the position is not.

    (3:50) *GE: **_"Why didn't nature give us eyes in the back of our head?"_* ... That is a great way to describe another "possible" world. Consciousness (Existence) has a single, primary objective. It will use all means available to achieve that objective. Existence is logical, experimental, and highly efficient. Existence will only execute logic-based experiments in the most efficient manner to move closer to achieving that objective.
    As far as *"eyes in the back of our head"* goes, Existence did not logically conclude that this was necessary to get the job done. Two frontally positioned, binocular eyes were deemed all that was required based on our physiology.
    *(1)* One wheel is all that is logically required for a unicycle
    *(2)* Two wheels are all that is logically required for a bicycle.
    *(3)* Three wheels are all that is logically required for a tricycle
    *(4)* Four wheels are all that is logically required for an automobile.
    All of these examples demonstrate how humans logically address transportation. At the end of the day, humans mimic "Existence" in everything we do.

    The Theory of Universal Functions is the science behind the OBSERVATION that natural processes are like ... unnatural processes. There is a scientific explanation why the Universe & Life are like ... a machine. Everything is a Function. Matter, Energy, space, time and the Laws of physics are Functions.
    A Function can be Abstract ( Time, space, Laws of physics) or concrete(matter, energy).
    All functions have a set purpose, role, or rules .... and will PROCESS inputs into outputs.
    All Functions are unnaturally made by an intelligence who must provide the INFORMATION for a function to exist & operate.
    Science relies on the Laws of Physics which are Abstract Functions, and can only explain natural phenomena because of these fixed Laws. The scope of Science is limited to our Universe & everything that belongs to it.
    The Laws of physics ... determine ... what is or isn't possible ONLY within our Universe. And our Universe is a Function composed entirely of Functions ... that was UNNATURALLY made by an intelligence not of our Universe.
    Earth is a Function, composed entirely of functions ... that was UNNATURALLY made by an intelligence not of our Universe.
    Life are Functions composed entirely of functions ... that was UNNATURALLY made by an intelligence not of our Universe.
    Science & the Laws of Physics ... tell us there is ZERO possibility of other Worlds or Universes without an intelligent Function maker. To say otherwise is simply science FICTION.
