Write your reply.

assistant: The "raisin cake" analogy does allow easy demonstration of how
 the distance between different raisins increases differently
 with time depending on their separation. The main problem with
 it is that it does not address the much more fundamental and
 widely misunderstood issue of "what is it expanding into"
 correctly. The "cake universe" is a 3-D object expanding into a
 3-D space which already exists. The inhabitants of the "raisin
 worlds" in the cake are by definition 3-D creatures and hence
 capable of sensing and measuring the "space" into which their
 universe is expanding. They can for example "point" in a
 direction and say "that is the direction we are moving". That is
 utterly different from the 2-D beings living in the 2-D balloon
 universe who by their complete lack of ability to perceive a 3rd
 dimension are unable, in principle, to sense in any way the 3-D
 space into which the balloon is "expanding".

Write your reply.

assistant: But the "real situation" as far as we can tell is that all space
 is increasing including the distances between stars in our
 galaxy and the distance between atoms in your body ;-) Happily
 the rate of increase of distance between any 2 points is
 dependant on how much distance (or more correctly "space") is
 already between the 2 points. The Hubble constant is of the
 order of 50 km/sec/megaparsec which means 2 points originally 1
 metre apart retreat from each other at a velocity of
 approximately:
    1.62 x 10^-21 metres/sec
 due to Hubble expansion ;-) So, over the estimated life of the
 Solar System of 10 billion years the reference metre will grow
 by about 2.56x10^-4 metres or about 0.26 mm ;-)
 Hubble expansion occurs everywhere but is only significant for
 things which are very large like distant galaxies ;-)

assistant: Hi,
 That is a pure example of where maths fails reality
 Irrespective of the speed of expansion the fact that it is getting larger
means that the matter in it must be thinning out unless new matter is being
created within the boundaries. Hence, eventually we would get ot the point as
Arnold said where the matter was that thinly spread that even atomic
structure could break down, except that apparently that is not psosible.

AGG has already reminded us that cosmological expansion has a negligble
effect when compared to local gravitation and atomic forces. The
question is therefore if the macroscale affects the constants of the
microscopic scale such as, obviously, the speed of light, charge to
mass ratio, fine structure constant, etc.

 situations and the "balloon people" could do the same around any
 curvature of their space, for example imagine the effect on
 their observations if you pressed your finger into the balloon
 casing a deep "dimple" in it. What I was trying to say is that
 we cannot observe or measure in any way whatever our space is
 "curved" in just as they cannot for example detect the
 "finger" since it is "outside" their space. They see a
 "gravitational anomoly near the finger. If you stick the
 finger "through" the surface of the balloon (this is an
 imaginary balloon so the air won't leak out ;-) They would be
 able to experience the round or elliptical "edge" which it
 caused but not the extension of the finger away from the

Write your reply.

assistant: 42 km/sec/megaparsec. Its a bit of common and (within the
 cosmological "club" permitted) unit sloppiness. In the "biz"
 everyone knows the units and they are often dropped as a result.
 It is a measure of the apparent rate of recession of objects as
 a function of their distance from us. The main reason it keeps
 changing is that the methods used for determining how far away
 things are from us at distances greater than a couple of hundred
 light years (a very tiny distance in cosmological terms) are
 very inferential, each making assumptions based on previous
 assumptions. The net result is that every time we refine/correct
 our idea of the distances to relatively close objects that
 directly and sometimes drasticly affects our value for things
 which are much further away.

Yes, he did.
Gamow proposed that many of the heavy elements currently found in the
universe were synthesized by "thermonuclear reactions" which took place
while the universe was very young.
To me the intended meaning is clearly BANG!
Consider this, why anyone bothered to use the word BANG to describe the
primordial creation event if it wasn't meant to be taken literally and
then to further add the qualifiers BIG and HOT as in HOT BIG BANG?
I feel it is plainly mistaken to suggest it was not an explosion; a
matter explosion which expanded into a space which was either already
there or forming and unfolding just a few scant moments ahead of it.

I've always heard that if the universe had been created differently then

This implies that the current properties of space are a direct
consequence of the progenitor events which unfolded at the BB. In other
words the very laws of physics could have had many different outcomes.

Gravity and Black Holes (18 Feb 98  17:02:26)
Here's an excerpt from a news report:
"the Rome scheme encodes one of the entangled photons with a specific
 polarization state and transmits this state to the other entangled
 photon. Although different from the Innsbruck experiment (which had a
 25% teleportation success rate) and the original theoretical proposal
 for teleportation, this scheme works 100% of the time if the receiver
 applies the right transformations on the second photon. (D. Boschi et
 al., upcoming article in Physical Review Letters)."
I see the words "transmits" and "specific". As far as I can understand
this stands for real information. I also read "100% of the time" and not
random.
Good answer... that says what it is but what does a photon mean, what
does it represent? The above experiment doesn't care what a photon is.
We already knew that. What isn't known is what it represents. The photon
can't just simply exist, it is not an abstract theorectical concept.
The above experiment implies it also transmit its original context.
So a vector particle at minimum has momentum, wavelength, and identity.
i.e. this photon belongs from there...

It is not only high gravitational situations which exhibit curvature.
Distant galaxies exhibit redshifts because of spacetime curvature not
simply by the line of sight recession one might assume.
When we look at distant objects we are looking back to a time when the
universe was smaller. Thus we can in this sense indirectly measure
curvature. Just as your balloon people could draw a series of circles
and discover that the value for pi is not the same for very large radii.

assistant: The information appears to be transfered instanteniously because it goes
not only thru space but also thru time. See quantum transaction theory
(or whatever it's called - always was _terrible_ with names) for futher
details.
A photon is a quanta of energy (don't ask me what energy really is -
nobody knows). Momentum of a photon is directly proportional to it's
frequency which is inversly proportional to it's wavelength. Frequency
is also directly proportional to the _amount_ of energy that a photon
carries.
You're _very_ right on this one. The more we know about our universe,
the more complicated it gets - more questions arise with each new
discovery than answers. How simple was life in 15th century? Everything
was explained by the bible.
