    The speed limit is light speed. The idea that areas of space can expand separately and so overcome it, is nonsense. The four physical dimensional hypersphere is the only way expansion can work but there is no evidence of a fourth physical dimension (or all the other dimensions that strings require). At present, a good part of cosmology is mythology. The people that demand evidence for anything different from the big bang IDEA cannot give evidence for what they claim is science.

    MarcAC. If mass curves space, that suggests that space has an actual structure which can be deformed.

    So the sun isn't growing?

    Not in any sense that has to do with the expansion of space.

    Eventually, when it becomes a red giant, it will 'expand' significantly... but that has nothing to do with the expansion of space that we are talking about.

    Mass curves space in our mathematical model of space-time. The model works amazingly well to describe and predict things, but you are taking it too literally. Space is not a physical 'thing' that 'curves'.

    I might agree, kaneda - what keeps science going is fresh and competing perspectives. Looking at it one way may help solve one part of a puzzle, while looking at the other way solves another part. Not wise to limit yourself to one perspective.

    This is getting way above my head now... My yearly visit to this site has come to an end. I must get back to the real world...

    We can argue about what space is and isn't til we die but it is still and will be what it is.

    Yeah, what's the matter with you, thinking words have definitions?

    You mean the sun is expanding and the universe is expanding? Heresy!!! We know for a fact that the Earth has remained a constant size for the past 4.5 billion years. I just checked my time machine and crystal ball: yup constant size....:crazy:

    Strings and inflation are not synonymous. The notation of inflation predates string theory as a major physics model.

    And I've explained why a hypersphere is not the only 4d shape which can be compatible with inflation, you never retorted.

    You continue to lie, either because you don't, and almost certainly can't, understand.
    He didn't say that. He said the Sun will eventually expand, once it can no longer burn any fuel. Look up what happens to main sequence stars. Yet another example of you failing to understand what people say and making no attempt to do otherwise. And there is evidence for the universe expanding.

    What OIM is doing is in a sense worse than lying, and it isn't out of ignorance. He is extremely adroit at using red herrings, ad hominems, Ignoratio elenchii, affirmations of the consequent, denials of the antecedent, non sequiturs, ... You name the logical fallacy, and he knows how to use it. (He does a lot of lying too, but fortunately that isn't a sin because his god has given him a pass on lying and slandering when it promotes his god's faith.)

    I used to link Oils is Mastery with Draqon. There are subtle connections.

    What is space?

    The universe fits in your hand.........

    Precisely. Cosmology in places edges into pure speculation and until we get something concrete, other ideas should not automatically be dismissed because they are different.

    Right. When we talk of gravity holding us down on Earth, we don't talk of being in a gravity frame that holds us in place. I think it is more apt to think of gravity as a net, dragging things around, which is tied to rotation (since we don't have it in a north to south direction).

    I see your holiday never improved your PIG manners. To point out why YOU are lying, I showed that any shape but a sphere would leave major inconsistencies in the universe. Obviously it was too difficult for you to understand, which is your problem and not mine.

    Where did I say this, so unleashing a torrent of loony ranting from you, LiarNumeric? How many times did you fall on your head whilst on holiday? Double figures? Treble figures? I can't understand why since there is nothing in it, so you are not top heavy.

    I suppose when someone is as ignorant as you prove to be, merely copying from science sites, what else can you do except rant about others, thinking everyone is against you?

    That is not why they are dismissed and you know it.

    Case in point:

    If this was different and made sense, then people might take it seriously. But to me this is meaningless dribble... what rotation are you talking about? The Earth's? What do you mean 'we don't have it in a north to south direction'? Does that mean we have it in an East to West direction? At least this time you put 'I think' in there instead of stating it as if it were fact like you regularly do.

    People don't dismiss your ideas out of hand. They give you reasons why they are wrong or at least unlikely. The problem is that you ignore their input and put your "different" ideas forth as if they were mainstream science.

    Maybe cosmologists should take a closer look at other disciplines such as astrophysics, subatomic particle physics and quantum physics. It appears to me that they don't really communicate very much with each other. It's too fragmented!

    They are fragmented. It didn't use to be like that.

    They have become fragmented because they are way too complex for a single brain to understand! You need a team working together to do it. And that's quite a challenge considering the limitations not only of our communication processes but also the limitations of our languages' capacity to communicate the complexities of those disciplines!

    And where did you do that? You didn't even know there were other shapes which are compact in 4 dimensions! You admit there's no evidence for a hypersphere shaped universe because we don't see copies of galaxies on opposite sides of the sky and so there's no evidence the universe is a hypersphere.
    Nice example of you not even reading the thread. I quoted someone else but typed out the 'quote' tags myself and didn't put their name. Anyone reading the thread knows that I was referring to someone else.

    Funny how you say I've got 'pig manners' and 'loony ranting' when you show exactly the same.

    Still waiting for evidence I'm a mod on physorg or all I do is copy websites. Why are you unable to find a single place I've copied and pasted from? And why are you ignorant of mainstream physics if, in your own words, a 10 year old could find this stuff?

    You admit you're inferior to a 10 year old.
