Newton defined gravity as a force acting across a distance. Totally pragmatic theory. Not for one moment did he believe it. He KNEW it didn't represent reality. Useless theory? No. Junk science? No. Accurate description of reality no.
But there IS something there that DOES cause a pull across a distance. Yes... or no? Just because he didn’t know the mechanism, particle/wave/space-time curvature/magical pixies/whatever doesn’t mean it didn’t accurately describe reality. Furthermore, just because something MORE accurate came along later does not mean Newtonian physics was way off or not an accurate description, just less accurate that the current description.
No, massless particles do not exist, no more than space and time are "curved".
Flat out denial doesn’t change the facts.
A single photon can be ‘captured’ and measured:
Detection of single photons using a field effect transistor with a layer of quantum dots
and yet they have wavelength which only waves do, and no rest mass. Which means... massless particle.
Mass refers to the amount of matter in that particle or cluster of particles.
Acceptable.
If that amount is zero, stop calling it a particle.
Unless it exhibits undeniable particulate properties.
When you start coming up with ridiculous conclusions, at some point it becomes time to start asking, "Maybe there's a problem somewhere in the assumptions." For a long time many experts believed that classical physics was true. That changed. Now most people believe that Einstein got it right. But we were wrong at least once before - maybe we're wrong again?
Such as... “All scientists are wrong because I can’t comprehend what they’re going on about?”
It may not be 100% correct, we may always discover things, but that does NOT mean that what we do know and can experimentally verify is false.
A human can't produce a humanly unintelligible theory? I'll give you one right now: A square circle.
That’s a contradiction, not humanly unintelligible.
No one's ever going to "understand" a square circle, or a massless particle, or a speed of light constant for all observers.
Except we do 2 of those 3, with the other being a contradiction.
An internally self-contradictory concept will never be "comnprehended" regardless of its pragmatic value.
And 2 of 3 three aren’t internally self-contradictory.
Here's an example of a pragmatic theory which I would NEVER want to abandon (it's extremely useful): in math, the idea of a point in space without any size and shape. Zero dimensions. Thus if you have an x,y coordinate system, the point 0,0 isn't presumed to have any size and shape. Fine. But if you tell me that you just identified a particle of no size and shape, or a region in space with no size and shape, that's insane. Any ACTUAL point in space has dimensions.
That also isn’t a scientific theory like the particle/wave duality of elementary particles is, or special relativity, etc etc etc.
No one denies it's a judgment call. But it's fun to see confirmations of my judgments, for instance when I send a simple challenge to a physics professor, and still haven't heard back for three months.
A mere non-reply doesn’t mean the challenge is unanswerable. Perhaps it got lost in a shuffle of meetings. Perhaps his research is demanding a ton of his time. Perhaps he got put on a long, intensive tenure deciding board. Perhaps there are textbooks out there that answer the question so he feels he doesn’t have to.
Not at all. You keep saying it doesn’t accurately describe reality. Yet, it accurately describes the speed at which things fall on Earth, on the Moon, in various regions of the solar system enough to send satellites out, on Mars, at various orbit distances from the earth, and so on. Just because the mechanism isn’t understood doesn’t mean it’s incomprehensible or self-contradictory.
That just begs the question. Newton claimed that a force acting at a distance is too humanly unintelligible to merit credibility.
Because goodness knows humanity’s knowledge in those fields hasn’t advanced at ALL since Newton.
I'm open to theories of gravity, and I'm open to theories on magnetism. But only the intelligible ones.
And intelligibility is something you can define, an unquantifiable variable, that you can use to reject anything you don’t understand or don’t want to take the time to learn to understand.
Right, just like we know a square circle exists.
So things ARE NOT magnetically attracted over distances and that attraction IS NOT varying in magnitude according to distance?
I said that many widely accepted theories are unintelligible.
And I say that the scores of scientists who understand, research, comprehend, and successfully utilize said theories show you wrong.
If we want a theory that accurately describes reality, we shouldn't spend centuries extrapolating assumptions that don't make sense.
You know, I fully agree with you. But that isn’t the case here. Lots of things do make sense, if one has the foundation of knowledge to understand them. Not everyone does, hence the length of time higher degrees take. It takes time and schooling to learn why they make sense.
Is this a push theory? Or a pull theory? Sounds like a push theory, which doesn't seem very promising. But I'm open to new ideas.
If something has mass, maybe. Inertia and all that. But try and deny it as you will, we KNOW of massless particles, and we also know of massless waves. So there COULD be a pull wave with no problems and nothing associated with your idea of ‘push’.
God is a moral agent. If it's never appropriate to suspect a moral agent, then CSI is an inappropriate endeavor.
You’re drawing a false dilemma. CSI is around to determine what happened, and from there whether a moral agent was responsible or not. In some cases, it cannot be immediately determined. For example, is this skeleton with chipped bones a centuries old one that’s been in too many sandstorms, leftovers from an animal attack, or someone that was murdered with a chainsaw? Gotta figure out what it IS before it can be determined if their is a moral agent to look for. In some cases there is a head start, processes that only happen through human means (guns do not levitate to chest level and fire on their own, and the household cat sure didn’t do it).
Right, sort of like I know that I can't pull or push you from a distance. Wait a minute, how do we KNOW that knives don't pick themselves up and stab people? Maybe we just haven't found the mechanism yet, just like you said? Let's give the scientific community a a few hundred years to find it. In the meantime, don't put all those so-called "killers" in prison. That would be unscientific, after all.
You DO exert a pull on me from a distance. You can’t control it. You have mass, therefore you have a specific gravity.
Furthermore, you’re taking the idea of the unknown mechanism to absurdity. We know of forces that exist that we just don’t know the carriers yet. Gravity is one. No such thing is involved in macroscopic motion like being stabbed by a knife.
We don't know...We don't know...We don't know...Ok, until we DO know, I'm going to (tentatively) embrace a theory that DOES answer the hard questions.
And do WHAT to find the answers? After all, you have your answers. Oh, wait for people who don’t accept your idea (which is NOT a theory in the scientific sense of the word) to find answers, if they’re findable? I would call that being a hypocrite. “I have no idea what did it, so I’m going to assume unscientific X is the cause until people who don’t find it out for me.”
You speak of energy fluctuations. I don't think you're making any sense.
That’s because you (apparently) haven’t had schooling/class/homework exercises/etc dealing with quantum stuff. But the fact that
I, and those who taught it to me, and those who wrote the textbooks, and those who conduct the experiments to verify it can understand and carry out those things indicate that it IS humanly intelligible.
Because: Again, we can't intelligibly postulate an infinite past. Therefore we are looking for the beginning of time and hence a state of motionlessness in which case an impetus is needed.
Which, IF your assumptions of some timeless lump of matter sitting there until SOMETHING caused it to move, a quantum energy fluctuation fits the bill quite nicely.
If Stephen Hawking wrote a book on square circles, I wouldn't consider it an accurate description of reality, no matter how pragmatic/ useful the theories presented. I feel the same about a book on massless particles and, probably, so should you.

And limit myself to your understanding in that field? No thanks. NO THAT IS NOT AN INSULT. For example, I don’t know what your education is in, but I’m sure no lawyer wants to limit themselves to MY understanding of the law. Or a doctor to MY understanding of medicine. Or a software designer to MY understanding of C++. And seeing as how you are not a physicist, I would not want to limit myself or the human race to YOUR understanding of it.
You're obviously not understanding me - or even Newton.
E=m(c^2) came after Newton.
Like, for example, an immaterial soul tangibly impacting a human body? It's a question of definition and therefore tautological. An intangible substance is by definition a sphere of reality insusceptible to tangible collisions. If you say that an intangible soul has a tangible impact on a tangible body, you're simply contradicting your own definitions.

You’re assuming collisions are the only way to interact with something.
Again, when faced with two theories, it is methodologically unreasonable (irrational) to opt for the one that seems completely self-contradictory / unintelligible.
And what SEEMS self-contradictory/unintelligible may wind up not BEING so upon further investigation/education/experimentation/etc.
