Spontaneous cause is possible. Read about the Norton dome. I don't see why it is nonsense. You can bend space with a stick in it even! If the universe grows older, a stick in it will get torn apart by expanding space. I would agree if you said you can't cut space in pieces. — EugeneW
I have always been mystified that adding one-half plus one-quarter plus one-eighth plus one-sixteenth etc adds up to one, in that adding together an infinite number of things results in a finite thing.
I can explain this paradox by understanding that relations are foundational to the logic we use, in that 5 plus 8 equals 13, etc, yet relations, as illustrated by FH Bradley, have no ontological existence in the world.
It is therefore hardly surprising then that paradoxes will arrive when comparing two things that are fundamentally different, ie, our logic and the world. — RussellA
We must be remember that when paradoxes do arrive, that this will be an inevitable consequence of the nature of logic, rather than indicative of anything strange happening in the world.
The fact that logic will inevitably lead to paradox explains why metaphor is such an important part of language, so much so, that a case may be made that "language is metaphor". — RussellA
.At any rate, shouldn't you be walking a dog somewhere? I imagine it suits you. — Constance
Not sure what you are arguing. We can bend space like a stick. If you rotate a heavy object, space is bend in the direction of rotation. Frame dragging. — EugeneW
No. What "bends" is spacetime, which does not have the Euclidean metric in R^4. The Euclidean metric is how we normally measure spacial dimensions. We need Kenosha Kid (PhD physics) to return and explain this stuff. :chin: — jgill
There is curved space - a type of geometry, and there is spacetime curvature, a way to interpret general relativity.
Empty space doesn't bend, IMO. :chin: — jgill
A building contains far more materials than the "blueprints, scaffolding and tools" (logic) used to build it. If your point is that, by analogy, "a map of the territory" (concept) does not exhaust the territory (object), I agree; but that does not mean that the latter is occluded or "falsified" by the former, only that one is (narrowly) interested in the latter (object) at a given moment in terms consistent with the former (concept). An astronomer, as you mention, does not project his "observational protocols and astronomical models" onto the stars anymore than wearing glasses with corrective lenses "corrects" whatever lies in the wearer's visual field. Logic, IME, is simply a way of seeing, so to speak, commensurable (to varying degrees) with the ways nature shows itself to itself (e.g. its 'intelligent' participants); this is so because, it seems, whatever else nature is, it is also logical (i.e. structurally consistent ~ computable (though, I think, not 'totalizable')). — 180 Proof
Which two? Alien territory and the familiar? — EugeneW
Why not? — EugeneW
Casually yes. Non-casually, after deep contemplation ("out yonder, is this huge world, which exists, independently of us human beings, and which stands before us, like a great eternal riddle; the contemplation of beckons, like a liberation"), no. — EugeneW
Space dont move. Only the objects in it. It can expand or contract but has no speed. The metric is the just the metric of GR. — EugeneW
Is bending curving? Space can have curvature. The metric can change. — EugeneW
That's a questionable assumption... — EugeneW
You can't bend space like a stick. You bend it with mass. — EugeneW
In 1912, Bertrand Russell wrote "On the Notion of Cause" in which he makes the argument that causation is not a useful way of thinking about the world. In 1943, R.G. Collingwood wrote "An Essay on Metaphysics" in which he wrote something similar. My point? It is not "absurdity" to deny the principle of causality. — T Clark
To know at all is to take up the world AS this knowledge claim is expressed. Taken APART from the knowledge claim, pure metaphysics. The cup on the table, e.g. is qua cup, a cup, but qua a palpable presence not a cup at all.
— Constance
I don't know what this means. More evidence you and I do not have the language to talk to each other about this. — T Clark
Well, they made the universe, with all life evolving in it. I don't think we made them.
You mean it's a conspiracy that both the gods and life are involved in? — EugeneW
Of course. But we also have to condition the subject, i.e, us. There is no such thing as "an observation". Thats already a theoretical claim. How and what we observe is not theory-laden but a theory, a story on its own. Space can have an objective existence, like the bending of it. A bend space(time) is a physical reality. The GW hunters at LIGO don't wanna chase metaphysical ghosts! — EugeneW
I dont think we are the gods. I think they made us. They had good reason. There are as many gods as creatures in the universe. We just play the game they played already eternally. From virus gods to hominid gods. The god story will be revealed shortly... Exclusively herd on Peee Eees Eeeef! — EugeneW
People used to think that there must be a luminiferous aether because they thought that electromagnetic waves had to have a medium to propagate through. Turns out they were wrong. I don't see how your inability to conceive of space bending without any outside space to bend in is any different. — T Clark
I don't think that any reputable physicist doubts quantum mechanics at all. They may argue about the interpretation, but I think that is a metaphysical argument, not a scientific one. Fact is, it works. As they say, shut up and calculate. It doesn't make any difference if you can understand why. Science isn't about understanding why things happen, it's about understanding how things happen. Your "...yet" is a bit too cute for my taste. Most physicists don't think further study will make QM any less counterintuitive. The world is not obligated to arrange itself in a way that fits into your way of thinking about it. You can't change the world, but you can change your thinking. — T Clark
It's a physical concept. Our perception of space is like it really is. We can move in it. Objects can move in it. It's the sauce between matter. It's the stuff objects can move in. — EugeneW
This, however, wasn't/isn't possible with the dichotomy paradox. Logic clearly demonstrates motion is impossible; observation, to our dismay, shows that motion is not only possible but actual (ambulando solvitur).
As you can see, a pre-Zeno reconciliation of rationalism and empiricism is impossible. We have to make a choice: believe our minds or believe our legs, but not both! We all know Zeno's preference: motion, in the Parmenidean umiverse, is an illusion. I guess this means Zeno, Parmenideans, were true blue rationalists. — Agent Smith
Zeno's arrow proves spacetime is continuous. The problem with discrete spacetime is particles moving in it and time advancing. Spacetime can't be broken up though and the nature of space remains a mystery.
Einstein's theory of spacetime showed we can actually bend space by mass. How mass informs space remains a mystery in GR.
The gods created spacetime. The reasons for their grounds remain a mystery.
That's a triplet mysteries. Performative contradiction, like I'm dead, are no mystery though. — EugeneW
Science is all about finding out situations where our intuition is wrong. Intuition doesn't come from the great beyond, it can be changed by experience and understanding. Do you also doubt special relativity and quantum mechanics? Those theories are certainly counter-intuitive. — T Clark
Is it wrong to think empirical science dis really not about the actualities lie before us. After all, the actual world is not a quantified presence; language and logic make it so;
— Constance
If this is true, and I think it is, why can't spacetime bend?
isn't science's claims about being about the world a hidden reification of logic?
— Constance
Everything put into language is a reification of something. Every word is reification. Reification and metaphor, that's all there is. I guess reification is the same thing as metaphor. — T Clark
Space is real, and I don't think space bending is a metaphor.
— Constance
Seems to me, most ideas refer back, or at least originally referred back, to something at human scale. That certainly makes sense with "space." Of course, there's always been space - the three-dimensional volume in a room, etc. I wonder if the development of the idea of space was changed by the development of Cartesian geometry. It certainly seems like it would have been as people learned that there were long distances between those bright things up in the sky. Science and science fiction probably changed the meaning of the word even more. General relatively just continued those changes and added another dimension. So, no. Space is not real, if by that you mean that it hasn't changed and can't change again.
And of course space bending is a metaphor. People can bend a tree branch or a piece of metal, but you can't bend air. Until, suddenly, you can. — T Clark
... isn't science's claims about being about the world a hidden reification of logic?
— Constance
I don't think so, I don't see how, especially insofar as logic consists of syntact translations of tautologies and function like scaffolding for building mathematical models of physical systems. — 180 Proof
Agreed that it can't make the case that it's rational to be rational on pain of circulus in probando. I'm telling you, I'm speaking the truth! How can you prove that, we ask? Well, I vouch for myself, I guarantee that I don't/never lie! WTFery!
The paradox is this: logic is the gold standard for proof but it can't prove itself without committing a fallacy, begging the question. I can't be trusted. Does this get an A for honesty and an F for intelligence? Logic, as it turns out, paradoxically, is a fool! The whole point to its creation and development was to build trust in a system that would always deliver the goods when it comes to truth. Yet, here we are, logic can't justify itself. — Agent Smith
Usually this expression is used in reference to spacetime and depends on a certain metric. Objects, however, become distorted by gravity and speed. Length contraction, etc. — jgill
On the contrary, misrecognized misuses (e.g. reification) of logic, or grammar, generates "paradoxes". — 180 Proof
General relativity is something different. GR is a theory, a model, which very effectively predicts the behavior of certain aspects of the world. Talking about space bending is a metaphor that helps people picture and understand what is happening. GR redefined what "space" means. I don't see it as a paradox at all. If you were talking about the different interpretations of quantum mechanics, I would be more likely to agree with you. — T Clark
Or is that your point? — T Clark
I don't think you're agreeing with Schopenhauer. The freedom is in thinking, according to him. Our actions then becomes caused by our thinking. So, what conclusion could you form about this? The necessity is in our action, but freedom is in our thinking. Determinism is misplaced here. The ocean example is to point to you that one could think about an action, but chooses not to act on it. — L'éléphant
I want the next misses in a puddle in a two please bikini, aloof in sheets coding, eternally farting years old (every tug has its toy.) Born in scence, upon scum, I prey with my wait paint which is wet point. — lll
Move him into the sun—
Gently its touch awoke him once,
At home, whispering of fields unsown.
Always it woke him, even in France,
Until this morning and this snow.
If anything might rouse him now
The kind old sun will know.
Think how it wakes the seeds—
Woke once the clays of a cold star.
Are limbs, so dear-achieved, are sides
Full-nerved, still warm, too hard to stir?
Was it for this the clay grew tall?
—O what made fatuous sunbeams toil
To break earth's sleep at all?
The nihilist is christ on the cross as he doubts the fondness of his too far father. — lll
As I see it, nonconformity is only ever partial if it's at all intelligible. I agree with Rorty and others that metaphors are mad, essentially senseless until assimilated by a mutating dance. Is Hooligans Wink a work of madness? It takes us back to Vico's divine men, poets without distance from their ghost-gushing imaginations, living therefore a thunder-hunted world of fairy tails. The proximity of madness and enlightenment reminds me Cambell's talk of the shaman as an ambiguous figure, a sort of necessary evil for the tribe, the one who forays beyond the fence, a bastard John Snow, secretly a king (unacknowledged legislator of moon kind.) — lll
I was thinking not of nostalgia but of a withdrawal of conformity sufficient unto the day to see the Right way as merely the tribe's way. I think of dogs trained by wireless leashes. — lll
Intriguing. Do philosophers (the 'special' kind) refuse to crow up? (Peter Pun asks Windy.) — lll
Perhaps analysis computes with the metaphors provided by revelation once they've cooled and congealed? — lll
I think you are on to something, though the word 'real' is perhaps unnecessary. As I see it, one task of the philosopher is to reveal so-called necessity as a congealed and disguised contingency which hides in plain sight. 'That which is ontically nearest is ontologically farthest.' Trapped in the illusion of necessity, deviation is not yet even conceivable. Possibility languishes unborn. Along these lines, the philosopher has an intensity of withdrawal that allows the too obvious to finally become questionable. — lll
I speculate that this 'one' is just reason or language, which is a unified system of concepts and a communal possession. The softwhere is one. — lll
Why must it be 'one' experiencing the model? What if the singularity of the ghost of the soul is part of a contingent and inherited model inspired by the perceived unity of its containing body? 'One is one around here.' 'One' can imagine a society where each body is understood to host several or seven souls, one for each day of the week, each learning to ignore what's not its concern on its six days off per week. It may be something like the unity of 'reason' that's projected on the body which is given a soul for its little prison palace. — lll
