    Default Space (Not Outer Space)

    Not long ago I saw an article that I want to go back to but I'm having a hard time searching for it. It was talking about "space" as in "space and time". Not Outer Space. Does anyone know of another term I could use for space? Every time I search for the word "space" I get outer space.

    I'm not exactly certain what your interest is, but you could try spacetime.

    Space, as in "Give me some space"?

    I like the suggestion of spacetime. They are also referred to as the third and fourth dimensions sometimes.

    spacetime was more of what i had in mind. The article I saw popped up to me (because of analytics no doubt) and discussed space only. It was a fairly lengthy article but unfortunately it does't look like I can find it. There is plenty to read about spacetime however.

    Space , in philosophy , may be 'as far as you can see' . This implies a boundary . Symbolically space can be a circle of three dimensions - beyond , within , and then the boundary . Yet the boundary is indeterminate to the adventurous . And inwardness may be skeptical . And beyond could possibly be unknowable .

    Space can be the great Ahhh! Mouth wide open , as a cave , the essential and expansive vibration within .

    You mean a sphere, don't you? A circle is a closed plane figure (2 dimensional) with all points equal distant from a given point.

    A mathematical space can have any variables you want, of any number, whether they be classical (x,y,z) or Minkowski (x,y,z,-it) or even Hilbert (x1,x2,x3...) used in QM, with an infinite # of variables... the properties of the space can be defined by set relations, metrics, completion theorems...

    Another kind of useful space is a time-ordered state space, such as Markov chains where each state has a certain probability of evolving to another state. These are similar to the spaces used in classical and quantum dynamics, where a system changes with time, and are used by engineers in communication and information systems, or actuaries evaluating complex risk mechanisms, etc...

    So when someone says "space", these are some of the possibilities that come to mind for me.

    Isn't a sphere more difficult to draw ?

    Well a circle is impossible to draw, so yes

    Space and time are merely different aspects of the same thing. One can be converted to another. Example: I dig a hole in my back yard a foot by a foot by a foot. Since I work carefully, this takes five minutes. I have converted five minutes of time to one cubic foot of new space. See, you don't even need complicated formulas for this!

    It’s disconcerting that some physicists say the guys at Cern are using the wrong value for a quantum mass. - see below - They’re off by many magnitudes! Theorists debate back and forth.
    Since there's a dispute about the rest mass of the quantum mass, those guys at CERN might destroy the universe with their probings.

    It's a scary idea that most all emerging tech-civs build a supercollider and something goes terribly wrong, at least locally. Curiosity kills the cats (aliens). There's so few emerging tech-civs nearby and in our time window that we probably wouldn't notice their self-destruction. Maybe we should pull back from Cern until we know what the quantum mass actually is, from more than one theory.
    Because if we dismiss time as a substantial dimension then the velocity of an object is not a function of increasing its speed in any direction, but rather the reorientation of its component energimes which are already moving at c so that -- the net vector of the component energimes provides a net velocity along an axis of motion. And so, the constancy of the speed of light is fundamentally more accurately expressed as the constancy of the speed of the energime. And a photon becomes nothing more than a system of bound energimes all moving in perfect alignment along the axis of motion. If we eliminate TIME like this - the quantum mass becomes 2.9 x 10^-73 kg. This is a dangerous conclusion for the CERN experimenters. They don’t want to hear it.

    How do you model "carefulness" in this formula?

    "they don't want to hear it"

    They don't want to dig carefully... what would Ken (or yourself) do in their position?
