Yes I do twake. Relativity.
Its the machinary behind the theory.
Speed up and you catch up to time.
Time going slower? Sound familiar?


Well, it sounds like lots of your posts. But that is down to a lack of
originality on the behalf of who ever wrote your code.

I asked you to show how you calculated the "dimensions curved" not for you
to post your relativity haiku.

Relativity implies a space-time which curves round large gravitation
sources. Different from what you have said.

Tom they say space is stretching inbetween
the galaxies. But this is not the same thing as
galaxies moving outward *through* space.


Very good.

I believe there is a distinction to be made
in cosmology.


Yes

Only if there is a center Porat.
This also means there is a place where space disappears.

No idea what you are going on about here. Your Haiku is broken.

Are you trying to say if there is a centre (which you think there is) then
the curved space (which you belive in) is broken?

Hmm. I can see insanity on the horizon.

The beauty of Einstein was his gravity is a cosmology where
there is no boundary of space - then no space.
The whole universe has a postive curvature a seemless whole.


Positive curvature? Are you sure about that?

You say space don't curve?
You think there is something wrong with that?
I say there is something wrong with a place that space ends.


Why does either have to happen?


How do you like that?

in fact
the more 'big ' we think about dimensions of space

the less we can know (at least now)

you say speric bundlies ?? why ?
may be because th e galaxies move outwards forn that
big bang point outwards in some velocity
but please note !!
even that is .... mass and pertiles dependant!!
it is they who define your space!! right ?
and it sates nothing aginst the exostance
of other endless space that is beyond that.
we cant know ...
and actually i doubbt if it is realy relavant to us ??
we ahve enough problems to solve in our 'little space'..

i just wonder what is 'positive curvature'
or waht is it megative curvature
is it not simpler to think -
no curvature at all??

yess
i think space nearly by definition should not have
any properties except hosting matter.
the properties are in the particles
they are much more 'equipped' and much more sophisticated
than the 'dumm space'.... is it not a better logic?
not to mention that if realy
galaxies are moving out in stright lines
imho it is a deadly problem for curved spacetime..

Photon has no mass. That is why it can travel at c.
Anything with mass travel less than c.
What is your arguments and proofs that photon has
mass?

Ops, the reply above is supposed to be in the thread "Pair Productions

Yes. If you follow your logic that space cannot
curve then it has to have a space then a no space boundary
where space just ends.

Einsteins cosmology is that the curvature closes
the universe and there is no boundary like there
would be if you were right!

No curved space?
A Space then no space boundary?
I don't think so!

Unless you accept the fact space is infinite.

Einsteins cosmology is that the curvature closes
the universe and there is no boundary like there
would be if you were right!


This is an interpretation. If the universe is closed then travel far enough
in one direction and you return back on yourself. This has not happened in
the observable universe so isnt a testable theory.

No curved space?
A Space then no space boundary?
I don't think so!


You say that a lot. I think it implies you dont think.

Sure, Nick. What in your opinion is the distinction to be made?

Let's take 4 galaxies having certain coordinates wrt each other. As
they move outward through space, they will move away from each other
and so their coordinates wrt each other must change. But they don't,
so what the hell is happening there? Well, the walrus said, the only
explanation is that since their coordinates remain the same but they
keep moving farther away from us, it must be space which is expanding!

I agree it _could_ be that space is expanding between them and us so
that they appear to be moving farther away from us, but I cannot
believe that is the answer to the phenomenon unless and until I hear a
mechanism for space to be able to do such a thing as expand.

Oh, sure, if space came out of the BB, it would be expanding along with
the universe, no? Makes sense, yes? But if space came out of the BB,
there would have to have been no space for the BB to empty out into,
and so the so-called unimaginable "Great Void" notion was created,

For me, space was here already and space cannot do such things as
expand, therefore, there must be an alternative explanation to that
silly one. My model contends that it is not space which is expanding,
but the Dark Matter in it. My model claims that DM came out of the BB
and is still expanding the edges of our universe. Some of it became
visible matter - that's us - but most of it is still invisible to us.
DM has much more to do with our universe than any amount of visible
matter has to do with it.

In it are the negative mass particles which cause the effects we like
to call anti-gravity, antimatter, and which will explain how galaxies
and indeed the universe can hold together. All visible matter was
created out of DM, thus DM holds the secret to visible matter in its
interactions with energy both negative and positive. The so-called
"fields" and random appearances of particles in the "quantum vacuum",
electricity and magnetism, are all effects of the DM interactions with
other DM and with visible matter.

It is the new frontier of space and the sooner we get to looking at it
the sooner we will better understand that which mystifies us still.

Space cannot expand, dilate, stretch, warp, curve, fole, bend, etc.,
etc., so stop saying that it does that! We can reasonably assume that
DM exists and so we no longer need space to do all the gyrations true
believers claim that it does. DM can do all those things and more,
much more. Just wait and see....

One way time would slow down.
The other way time will be the same
for all galaxies.

I say if galaxies aren't moving through
space TomGee then there can be no relativistic
effect on clocks. Space stretching is not the same
thing as galaxies moving through space.away
from each other.

There is a distinction to be made.

prove - proof
stright - straight
than - then

The straight lines are off the universe.
