Re: Guesses, you say
simple
Why does something tell me a lot of your explanation would be theoretical? -If you actually could give one, and aren't just assuming if you stayed in school for another 20 years, you'd know!
What he is trying to explain is that the physics of the gravity requires a sufficient background in the mathematics to even have any sense of how gravity manifests.The everyday world is more complex than appears to our limited senses. The world has subtle ways that are not obvious by any other means but mathematics.

But I realize now that these people were not in science; they didn’t understand it. They didn’t understand technology; they didn’t understand their time.

Re: Guesses, alright
simple
But no matter how complicated it may be, or you think it is, a lot of that complication exists as a matter of fact, only inside your heads. This is because, much of the math is directed towards guesses of what is beyond the known
Not at all. The mathematics is Not guess work but a reliable means of being able to make predictions about the way things work. If the mathematics of the model are correct they will accurately describe a result that can be expected from an experiment.The experiment will reveal value for a given phenomena than can be checked against the predicted value.
Only what is it exactly that causes gravity to exist, and "Exactly why two masses separated in space have a gravitational attraction to one another.."?
But you can have no insight into that without having an understanding of the mathematics involved. Without understanding the language nature operates in how do you expect to realize how this really works?
Do you understand Quantum mechanics?

But I realize now that these people were not in science; they didn’t understand it. They didn’t understand technology; they didn’t understand their time.

Re: avoid time waste
simple
The link you yourself gave me to check out, similar to what they say about gravity links I've seen, has this to say...
"It is important to realize that in Physics today, we have no
knowledge of what energy is. We do not have a picture that
energy comes in little blobs of a definite amount.
It is not that way
You have responded to the wrong person in the wrong thrad here simple. This was a website I gave you over in the general relativity thread, to which I still have not got a reply.The lack of understanding about what energy is does not apply to the gravity topic.

But I realize now that these people were not in science; they didn’t understand it. They didn’t understand technology; they didn’t understand their time.

Only in the limitations of the physical universe
You have any presentable evidence that there is a universe that is not physical?
Like Newton's gravity has it's place, so there is a limit to philosophical math. No one doubts it would work here on earth, within it's limits
I do not understand your objection here. Are you disagreeing that the laws of gravity are universal?
We can't check whether there is more than a physical universe, we can't know a lot of things.
If we cannot check then why asssume? Which specific things can we not know?
Even some basics, all we know is how they work. Putting guesswork out of the range of normal men doesn't make it less guesswork, only less accessible guesswork.
Even some basics, all we know is how they work
What more do you want to know about things?
I didn't ask for insight into it, just for you to tell us if you could if we know this exactly, and, then, if you could explain it. I also am not convinced nature doesn't speak more than one language!
If you are not willIng to learn the language then how do you expect to understand. Add to this that the language does not have a simple translation because nature does not provide a roseta stone for this.
You can believe that there are more than one language but that does not make it so yet if you do not take the time to acquaint yourself with the language we do have then how can you expect to learn of any others?

Do you understand Quantum mechanics?
Not much, do you?
No one does yet it is the single most successful theory in terms of accuracy of theoritcal prediction values to experimentaly obtained values ever. The things it shows us about the world are counter-intuitive and correct.Nature is pretty weird and the fact that you do not understand the workings of quantum mechanics is no problem but our understanding of how it operates is also dependant upon the mathematics.

But I realize now that these people were not in science; they didn’t understand it. They didn’t understand technology; they didn’t understand their time.

Re: Guesses, alright

The evidence that exists on earth is of a type that science is not yet able to deal with, and here, in reality, they are nowhere near up to snuff!!Ha. Two can play at that game. The evidence that exists on earth is of a type that science is not yet able to deal with, and here, in reality, they are nowhere near up to snuff!!
You break my heart simple. You have nothing to present and you clothe it with an attire completely inappropriate. It is not a game that science deals with but with demonstratable evidence and models. You claim that science is not able to deal with evidence which you do not present.
If you wish to present demonstratable evidence that anybody anywhere can repeat and assess for themselves then by all means quit being vague and lay the cards on the table.
Well, this forum is too restricted to discuss the routine overriding of the finite universe present gravity guidelines! The question remains, however, what is the 'universe'? Is it just time and space, and what we have discovered, or is there more?
Just Time and Space!!? JUST TIME AND SPACE you say!? Within those two phenomena physicists of every ilk have been bleeding brain cells and investigating and refining the tools of investigation and pushing the boundaries of the mathematical models for centuries and you speak of it as though it were vacuous drivel!
Of course there is more old man, great, voluminous reams of uncharted territory but we have made astounding discoveries that are bypassed by most people. That you press upon the ground with a certain force does not surprise you and yet it is a direct consequence of Newton's Laws that we realize the Earth "pushes" back in kind. That time moves slower for people in L.A. than in Denver is an understanding gleaned from relativty yet both these things are not obvious to the "common sense" of men. What "more" do you require?
Bottom line, though is there is more than we now see, and I would call what we see the physical only universe.
You would call it that by what dint of imagination? What precisely leads you to assume there is more than this if you do not have evidence of it? You have no idea of the construct of the universe as has been revealed through rigorous application of reason and logical insight yet you claim there is more. Give it up simple and show us reasonable explanations for your position.
Are you kidding? What more would we want to know about a light switch than, all we do is flip it, and the light goes on?! Some want to know more than how it works.
Fine. Then to what level of understanding do you wish to go? Do you want to understand the wiring of your electrical circuits? The infrastructure of nuclear and hydroelectric generating plants and their grids? The motion of electricity in copper wire of varying gauges and under varying conditions? Or how about the emission of photons as a result of the electrons dropping from a probabilty cloud of one energy to another of lower energy? Science can answer these and far more if you are willing to delve into it. All I can say is dig in your heels and put the gray matter to work by taking the courses you require to satisfy yourself.
You can believe your math is the only language, that don't make it so either. Any language that takes decades to learn couldn't hold the true secrets of the universe anyhow. Sounds like those that learn it can't explain it in english, and generally don't really understand a whole lot anyhow, about a whole lot of things. No wonder they need new physics. You ain't deep, you just ain't clear!
That is absolutely correct simple. Math may not be the only language yet I do not make the claim that this is so. Beat me into submission by presenting a language that does as well or better and that others can access if they put in the effort and we will see if it stands up to scrutiny. If it fails,it fails, so what? But if it holds together logically and can point out previously unknown phenomena that we can discover by the means your language points the way towards then have at her big guy. Just make sure it is capable of describing things at least as well as what we already use.
OK, so let me get this straight. We don't understand it, nobody does. OK got it. Now, all this understanding we don't have is based on math. OK, got it.
No you don't got it but not for the reason of us not understanding what is happening but that what is happening as revealed by quantum mechanics is nuts. It makes no sense. If you have an hour or four check out this site for a lecture given by an icon of the field and see if you "understand" it better than anyone else.
Page Redirection
This would be a far more reasonable stance to assume than snips at thread context that you have not properly assesed.

But I realize now that these people were not in science; they didn’t understand it. They didn’t understand technology; they didn’t understand their time.

If thats all you think there is, that is no surprise.
Not at all. There is far more than spce and time since we also have the enigma of mass energy.And those are simply the groundwork. The phenomena produced by the interaction of these gives rise to the world we exist in.And as for it being no surprise do you suppose you would care to qualify what you mean by that statement or do you just wish to be vague as well.
So an insignificant time difference, and a partial understanding of gravity is all one should or could wish for? Uderstanding more tha the average common sense of man, I would agree could be interesting.
What insignificant time difference are you referring to? A partial or total understanding of gravity is not the point of discovrery but the engaging of your mind to see the connections or patterns of nature and realize how subtle and magnificant they are.

What makes you assume there isn't if you have no evidence about it?Dint of imagination?
Bravo,14gipper, you precisely answered nothing about the question that was asked and at the same time managed to produce a meaningless question in response.
Why for example would some talk of a new physics needed, and coming, if the dints of the old were sufficient, I don't care how much time they spent learning them?
By new physics is not meant an abolishment of the old but a fresh perspective on the present model.Any presentation of "new physics" must answer not only that which the present cannot but also explain the bottleneck or restriction of understanding that the present is mired in.
Do we know his idea of a constuct? How would you say he has no idea?
? I did not ask his idea of a construct{whatever the heck that is} though I did inform him that he had no idea of the construct of the universe as science has revealed it to be.As to whether he has an idea or not I cannot say because he cannot say.
Perhaps he would have prefered one that is honest in it's limits, and was available in his appaently spoken tongue of english
Well cry me a river 14gipper,but the native language is not ours to whine about.The common tongue of english is wholly inadeqate to explain even basic concepts of science since precise meaning has long ago been tossed out the window. As for honesty what leads you to proclaim that we are not being honest? It is not lack of honesty on our part but a complete lack of willingness on simple's behalf to attempt to do the hard thinking necessary to see why we cannot explain it to him in simple terms. The structure of nature is not in simple terms.

Since you haven't found it, or them yet, how do you know if one shoed it or them to you, you would have anything able to scrutinize it with? Apparently, this isn't the place to even mention in passing anything that would be beyond physical! I read an article, that said they now need to rethink black holes, because it seems some gave birth to stars!!!! WE don't really know where these babies are popping out from, now do we
Since I have not found it yet I do not know how or if I could do you? Of course you can claim "beyond the physical" but you cannot demonstrate it and thus any claim can be made however outrageous and be totally within that realm. This does not make it a valid area of endevour ,however, you are free to pursue whatever you wish my good man.
As to your reference to the article I can make no statement as I am not familiar with it for you gave no info.

On that score, it seems one of the major criteria would be to come up with three words. "I don't know"!
I am perfectly willing to admit I do not know but that does not mean science as a whole does not. You seem to find it difficult to differentiate between the level of understanding in science and the level of ignorance in the science.The level of ignorance is vastly greater than the level of understanding but do you have any idea of how fast the border between the two expands even hourly?

Re: limits
simple
Right, more than the things that you said people were brain bleeding over
Yes but if you recall I was responding to this statement of yours
The question remains, however, what is the 'universe'? Is it just time and space, and what we have discovered, or is there more?
I was sensing,perhaps wrongly, that you were hand-waving aside the vast amount of understanding that is present in science concerning the boundaries of knowledge. that there is more to what people are bleeding brain cells over is just additional effort on the part of real thinkers.
I'll ask you as well, do you know what time is exactly? If not, there goes one of the two. In the veiw of some scientists, even the space bit needs to go, so whats that leave you?
That depends on what level of knowledge you are willing to acquire.
Time is simply a measure of a property of the universe. It is a dimension ,one among others that define the structure of that in which we find ourselves.
Now this is an exact accounting of what time is.However,there are subtleties that are at first not apparent but further study only reveals the details of the structure not a different nature of what time is.
Now,I will not argue the "view of some scientists" because you have not presented to me either their names nor,at least,their arguement that I might understand what this means.
"Most perplexing of all, spin nets and spin foam cannot be thought of as existing in space and time. They reside on a more fundamental level, as a deep structure that underlies and gives rise to space-time.
Certainly. That there is a deeper level is understood in science. The mathematics of quantum field theory required that there be a vacuum energy in order for the Heisenberg uncertainty principle to operate. There is,if you were to remove all matter and forces from the universe a "virtual" background of particles that flit into and out of existence continuously and constitute an enormous energy "potential". However because these particles exist for less than the Planck time they do not interact as such with our world. however the energy is measureable underthe proper conditions. This energy is extraordinary. A cubic meter of this zero point energy is capable of boiling the oceans of Earth.
As for you energy, I think it was you who gave simple the link that admitted it also is not known what it really is. Add gravity to the list, although some claim they know, in the elite higher knowledge of advanced math, but it would take years to explain! With all these limits to our actual knowledge, I think that those who portray a high priest attitude, and pretense of knowing everything (not that you do) should be taken to task, and knocked down a few pegs. I never sensed that attitude much from einstein, or Feynman, or many others, but some, on this forum wreak of it. Yet, would likely be the first to decry things like the unseen forces on earth at work and known by most men since time began. Making a few thousand loaves and fishes from a couple little loafs, and a fish are taboo, but making a universe from nothing, and expanding from less than the size of a proton, to a grapefruit in a fraction of a billionth of a second is science.
Energy is not known because the nature of it is purely mathematical and gives no hint of the mechanism by which it manifests itself. Gravity is well known because we can study the force of gravity and tie it to the structure of the universe. It is intimately tied in with the geometry of the universe and these things are well known in that we can make predictions of what it should do under given conditions and these predictions have always matched observed phenomena when we get the model correctly.
You also must understand the level of confidence that is portrayed within the mathematics and how the understanding we have of the fundemental forces allow us to say with what may appear to be "high priest" attitude {which I am sure does actually go on in some people} that certain things like walking on water or making more food from a given limited amount are not possible.
Like Martin Gardners carpenter puzzle when you understand the answer you immediately realize that there can be NO OTHER solution to the condition observed.
Evidence of what kind? The kind you could practice math on? The kind you could fit in a tube? Surely you have heard there have been evidences of more than the natural among most people on earth? Besides, I could give yo evidence of energy, time gravity, etc., does this mean you can explain it?
Evidence that can be replicated and experimented upon to determine that it is an actual phenomena and not the all too human propensity for error. As Feynman once said "The first principle is that you must not fool yourself - and you are the easiest person to fool."
This is why logic and math and careful reasoning are needed to winnow out the actual from the plausible,from the border line, from the mistakes,from the experimental errors,from the statistically insignificant, from the delusional,from the absurd,from the lies,from the attention seeking and from the impossible.
Feynamn also said that "Science is the belief in the ignorance of experts. "
Good, you admit that there is a restriction of understanding. As for any new physics, we really don't know if or what they will be, replace, or cause a rethink to anyhow. I wouldn't hold my breath
Restrictions of understanding nowadays is in the details and not in the general overview.The replacement of "old physics" with new alters only our way of looking at things which is artificial anyways. However, the phenomena themselves are what they are and follow rules regardless. These rules do not change as we study them deeper but are refined to reveal the next layer which also follows the rules of the higher level but add complementary rules that govern their level.
How would you know? Get by the restrictive bottlenecks, and get a grip on the core concepts. like time, and then maybe you can tell us something. It would be better to say something like 'our current understanding, or lack therof, of nature, indicates it is so complicated, it would take years to explain, and it could,'t be in english anyhow'.
The problem here is that you are not communicating to US what it is that we are failing to explain to YOU. If you do not know the question you are trying to ask how can you expect us to know an answer or to even postulate one. What is it that you do not understand that science is failing to give you reasonable means by which to inquire on your own?
So have you found the it that took nothing and produced the hot soup that gave us our universe?? Have you found the real nature and cause of many forces, like time, etc? Have you determined the finiteness or not of the universe, or many other things? Yet, what, you think you can turn around, and tell us that say, ghosts are not real? What even is 'real'? A universe from nothing is real, but something like non physical entities seen actually by millions are not real? Why, because you can't touch them? Can you touch a quark, or a Plackt unit?
But that is the point of the investigation and discovery. We find that "nothing" is different from our intuition about nothing, the vacuum energy of the universe which science has revealed is nothing and as a consequence the universe has a underlying structure that is different from the physical world we occupy.The world is subtle and requires that we give up our pre-concieved notions about it that we form through our senses because they are quite simply inadequate for understanding the real workings of the world.
Yes we have a good understanding of the interrelationships of many things and no we do not understand it all but what we do understand precludes the possibility of things like ghosts as ghost stories present themselves to us. Look ,a ghost that appears to a person,if it is real, is interacting with the structure of the eye which means it is using the electromagnetic force to produce the light which the structure of the eye physically responds to. That "light" can be measured and verified and recorded and we never find this to be the case do we?
I see no evidence that there is nothing else besides a physical universe at all, do you? If there is, we haven't scratched the surface of what wonders we may yet explore, somewhere, over the rainbow.
I see no evidence against invisible,immaterial things forever beyond our investigation? We can conjecture on that all we want but it cannot ever interact with us for then it would become physical with all the attendent restrictions and evidence.
