Non mathematical language can also do this but while it might be easier to understand it is also not as precise

Why is the effect of gravity stronger between galaxies when they just happen to be closer to earth

The effect of gravity diminishes over distance so the further away two objects are from each other the less effective it is
And so galaxies closer to our own will have a stronger gravitational effect between them than ones that are further away
You missed my point. There is NO bearing on the effect of gravity between two objects, just because those two objects are closer or further away from us here in the milky way.

The milky way, which is also some times referred to as "our own" galaxy, which by the way is a wrong terminology but i digress, anyway, the strength of gravitational effect BETWEEN TWO OTHER galaxies does NOT change JUST BECAUSE those two galaxies are closer or further away from the milky way galaxy. There will OF COURSE be some sort of different gravitational effect going on, if those two galaxies are closer or further away from the milky way galaxy, but NOT necessarily BETWEEN the two galaxies. For example, the gravitational effect between two galaxies will be the EXACT SAME no matter whereabouts they are in the Universe as long as those two galaxies are the EXACT SAME distance from each other each time. This is of course taking into account that there are no other things having an influence between those two.

This speaks for itself.

However this could not happen if there was any gravitational attraction between our galaxy and them
So its actually wrong to label it as weak gravity because actually there is no gravitational effect at all
You were saying; the effect of gravity is so weak and that is the reason WHY more distant galaxies are receding further away from our own.

I was POINTING OUT, through clarifying questions, IF answered OPENLY and Honestly, that the reason further away galaxies are receding away from us is NOT because there is a weak or NO gravitation attraction, which is what you were stating, but because the Universe IS expanding.

Is this now correct?

I should have explained that more clearly

The evidence comes first then the mathematics because evidence is the more important of the two
Evidence is the foundation upon which all of science rests and therefore comes before anything else
Okay so EVIDENCE is the foundation upon which ALL of science rests and therefore comes before any thing else.

You have stated: Red shifting is the actual evidence that the Universe is definitely expanding as well as dark energy

So, you are saying that there are two things, which is 'evidence' for the Universe expanding. These two being redshifting and dark energy.

"Redshifting" appears to be some sort of reasonable evidence, but why it may be NOT, can be LOOKED AT later, but for now considering that you did NOT reply to my question, What is 'dark energy' EXACTLY? I will have to now ask you did you not answer this because you just missed it, or for some other reason?

If that question does not get answered, then we will have to just move on as though "dark energy" is NOT actually evidence at all. It is NOT reasonable for someone to say, "SOME "thing" causes/creates the Universe's expansion", but when asked to explain what that "thing" actually IS, and the answer is something like: "We do NOT know", "We have no idea at the moment", or "Some things are not meant to be known", then there is just the EXACT SAME 'faith' based ideology that has been going on for centuries now.

If 'dark energy' causes the Universe to do some thing, then what it ACTUALLY is MUST ALREADY BE KNOWN, otherwise this is just the same as "God created the Universe" theory.

Either human beings HAVE 'evidence' for some thing or they do NOT.

So far 'redshifting' is the ONLY available evidence that the Universe is expanding.

Yes very true, but just remember that it is the mathematics, which you call "the language of physics", that also explained the observable phenomena, as accurately as possible, about how the sun DOES revolve around the earth. The maths accurately states that the sun revolves AROUND the earth approximately every 24 hours. This 'observed phenomena' was the EVIDENCE, and these numbers are the FACTS.

Coincidentally, just as an 'observed phenomena' WAS the "EVIDENCE" for 'the sun DOES revolve around the earth' BELIEF, in past times, so to the 'observed phenomena' of "redshifting' IS the "EVIDENCE" for 'the Universe is expanding' BELIEF, in current times, of when this is written.

Both of these parties, with these two BELIEFS, also used "observation" as "empirical EVIDENCE" and both parties also use "numbers" and "mathematics" as the "facts" to back up and support their BELIEFS about "what happens".

And, just as 'the sun revolves around the earth' ASSUMPTION/BELIEF was proved to be false so to will 'the Universe is expanding' ASSUMPTION/BELIEF CAN BE proved false.

Just because an 'observed phenomena' is called "EVIDENCE" this does NOT make the 'phenomena' itself true, right, nor correct. The 'observed phenomena' of 'optical illusion' can testify to this fact. (That was an intended paradox, by the way, if it was not noticed). Paradoxically; The 'observed phenomena' of 'optical illusion' IS the 'EVIDENCE' that 'observed phenomena' is NOT necessarily 'evidence' for some thing. For example, the flat earth observation, the geocentric observation, and the Universe expanding observation, IS NOT evidence that this is what the Truth actually IS. Coincidentally all have these observations are backed up and support with numbers and mathematics, which are called as "the facts".

A flat earth WAS (and STILL IS to some) demonstrably true.

A Universe expanding WAS (and STILL IS to some) demonstrably true.

So, are you SURE that IF some thing is demonstrably true, then believing in it is superfluous?
And, remember it is I who is continually saying BELIEVING any thing is completely unnecessary and in fact actually a detriment.

By the way how could one DEMONSTRATE an 'expanding Universe' is true, or not true?

If some thing is NOT demonstrably true, then BELIEVING it is true is based on 'what' EXACTLY.

Ah okay. I will search through those pages there to look for it.

I could NOT find YOUR explanation of what "dark energy" is exactly, so I LOOKED UP some one else's definition instead: Dark energy is an UNKNOWN form of energy which is HYPOTHESIZED to permeate all of space, tending to accelerate the expansion of the universe.

To me, this sounds very much like just another made up word, with an ASSUMPTION of what it "should" do, based on no known actual facts, but only expressed to just TRY TO HELP explain 'that' what is observed, and unexplained and as of yet inexplicable, which in this case is the 'expanding Universe'. A bit like the word 'God', with Its ASSUMED ability to do/create Everything, based on no known actual facts, but is only expressed to just TRY TO HELP explain, 'that' what is observed, and so far unexplained and as of yet inexplicable, which in this case is the 'Universe', Itself.
surreptitious57 wrote: Fri May 03, 2019 2:43 amAnd there is no faith or ideology involved here but just simple acquisition of as much knowledge as possible
So, has much knowledge actually been acquired already about what "dark energy" is exactly, what it actually does, and how it actually does this and/or works, yet?

By the definition of what I got, from another source, about "dark energy", there appears to be about as much acquired knowledge, by human beings, of and about "dark energy" as there is of and about God, Itself. And, from my perspective, that is just about NONE at all.

The reason human beings can NOT yet SEE the actual Truth of these very easily FULLY understood 'things' is because human beings, literally, ASSUME and BELIEVE otherwise.

The reason human beings have NOT yet EVEN BEGUN to SEE the actual Truth of 'things' is because they ASSUME and BELIEVE that they ALREADY KNOW what is True, Right, and Correct. For example, the Universe IS 'expanding IS True', Right, and Correct.

Is that an accurate picture of things?

You KNOW that the Universe is expanding because of the EVIDENCE and the FACTS, correct?

I relate a lot to your style, Will, and want to actually get into a comparative conversation of your book to my theory I've been working on for so long.

In particular, I like how you modeled the space per General Relativity's meaning and treating matter, space, and time, as all one concept related merely to the "shape" of space.
Thank you.

Well yeah, all we know for certain is the 'facts'. When ya really boil it down in the philosophical steamer, the facts are the phenomena. As Descartes pointed out, the source of the phenomena could be anything.

My issue with that is if 'matter' is just "shapes and variations in the structure of space", curves in your case, waves and whirlpools in mine (which reduce to curves, I guess), why aren't those "shapes" part of the process? Why doesn't 'matter' create more 'space'? So, for sections of the book, I just went along with the idea that it does.

Scott Mayers wrote:All that is needed in this theory is for empty space to come from nothing. If space IS nothing, this suffices and closes the theory.
The problem is that we can't do any experiments to find out how 'nothing' behaves, because we haven't got any. The space we have to hand is full of fields, gravitational, e/m, Higgs', and awash with neutrinos at least. We may never know whether the big bang (or at least the phenomena which support the hypothesis) occurred in something like the space we are now in, in which case it would be possible to interpret 'out universe' as simply a local phenomenon in some larger 'steady state universe', or all those things really were created ex nihilo.
Anyway, sorry for the delay getting back. I know there is a lot more to your theory and I think it is worth discussing.

As you might notice by this that I share BOTH Einstein AND QM but take Einstein's view that we need to assume no closure on theories that appear 'weird' and so should stick with a more agnostic appeal to those that assert an interpretation as such. On the other hand, I also agree to QM but with the approach of treating the 'probabilities' that appear trustworthy by any formal means to suggest distinct worlds. I believe that my theory will successfully combine the confusion of different interpretations to a more unified one.

uwot wrote:Why doesn't 'matter' create more 'space'? So, for sections of the book, I just went along with the idea that it does.
In my theory matter CAN create new space but not from matter colliding. It would be of a higher dimension and the "collisions" would require the literal curves OF their shared dimension to meet within the same paths they are moving in AND in precisely opposite directions. The odds of this occurring is more less probable (though possible AND real) but is NOT the same as what occurs when two particles collide. This needs better understanding of some prior issues that I'd need to prove first.

You might have gotten a hint from the last response. If we imagine ONLY one line as its own dimension, any collision is what occurs should somethings be transmitting from opposing directions by default. But when we add other dimensions, a 'collision' might be interpreted to include something from outside each of their linear dimensions, ....something, say, from the side. I want to be more clear to differentiate a side swipe from a head-on collision. They each can occur but only the 'head-on' variety would be most contradictory should one unique space be unbiased.

To help understand this, if we imagine two points that meet up within the same line from opposite directions, the result of this may cause one point to take a perpendicular turn to the right while the other one to the left.....to remain 'symmetric'. However, because we have more than a plane's dimension, WHICH of the infinite possible planes does this line lie on?

To me, these kinds of 'collisions' that have infinite options, is resolved by having an infinite set of worlds such that EACH option is taken. From the point's perspective, it is not like a pilot in a plane that differentiates uniquely an UP and DOWN orientation. The concept of "yaw" that a pilot might be able to do is also something that has to be considered. A 'twist' of a point spinning in the perpendicular direction of its linear travel could not be differentiated without adding even an infinite more sets of worlds that deal with these possibilities, for instance.

Anyway, sorry for the delay getting back. I know there is a lot more to your theory and I think it is worth discussing.
I'm trying to express a theory that is also a 'theorem' for physics. This theory is based on a similar idea that began with Pythagoras where he deemed everything is just number. If I didn't already express it before, given that 'nature' lacks conscious essence as a 'god', whatever reality could 'derive' from (or is 'manifest' a better word?), requires whatever makes up reality to derive from literally nothing at all.

Science, to me is a top-down process that we can INDUCE what reality MAY be. Then we 'guess' at how it operates moving forward, which is a bottom-up guess of the mechanism of reality,....its LOGIC. So while we may not be able to prove scientifically all that is real, we still can only use it as a means to try to guess at the ultimate logic of reality. Reality HAS to have done this without us and so, while we may not AGREE to some common human capacity to be able to prove what reality is with closure, I take issue with this rationale in light of nature being nothing to have proven itself able to manifest it all ....without some apriori science community it had to appeal to by some proof before it addressed its 'presentation' of reality.

So my point that has driven me to my theory was based on this. There HAS to be a complete rationale for Totality (not just our one Universe) AND we should be able to determine HOW reality creates worlds that include ours by some universal rationale or 'logic'.

My theory attempts this. I already am confident it works but it is extremely difficult to prove with any ease. It mixes both Metaphysics with Physics. I can combine the two approaches in a similar way as to the Fundamental Theorem of Calculus that links up derivatives to integration; and similar for the discrete to the continuous.

But it requires exhausting certain logical possibilities to each area of what we 'sensibly' determine about reality in our limited perspective and language.
