What do you think all those advanced species have been up to for the
last four billion years while we've very slowly been emerging from the
slime?
Sitting at home waiting to be discovered? <g>
Nah, we're alone, just like if we were on an island off the coast of a
major land mass. The fact that we can see no signs of development,
nobody has come to claim the land for Queen Victoria, and nobody has
turned up with a mining franchise or offers of Coca Cola, just goes to
show that if there are other civilisations out there, none of them has
hit on the notion of galactic colonisation.
Which seems peculiarly unlikley, seeing as we've come up with it just
like that and will probably put it into practice within the next million
years.
For rules of thumb analysts, colonisation takes about 20 to 30 million
years, allowing a million years for each world to become fully
exploited/populated. In an extra few million, the second galaxy becomes
full up. We've been around, living on an ideal candidate for
colonisation ("liquid water? Excellent") for thousands of millions. Even
if the first colonising species prefers to live on helium in the outer
planets, someone else will have evolved in order to prefer our own zone.
Emerging civilisations are potentially a threat; no successful
civilisation will ignore us. We'll either be incorporated into the
galactic co-prosperity scheme in order to shackle us to the status quo,
or destroyed out of hand if the dominant group are the "no nonsense"
type. It's highly unlikely that we'll be left alone to pump nuclear
fusion bombs onto their planets in the "what happens with this" stage of
space exploration.

Write your reply.

assistant: How so? Since evolution drives changes due to adverse treatment of
overly specialised creatures, it seems reasonable that evolution should
tend to produce general-purpose species capable of handling different
environments and thriving on the misfortune of other species.
I'll grant you that it won't be a process which will follow the same
pattern, but homo sapiens isn't a freak of nature. Homo neanderthals got
here as well, and are not ancestors but a different species.
If we hadn't been here occupying the niche, they would. There's no
doubting that aliens would have different dna and inherited genes, but
they'll very probably turn out to be intelligent apes of one sort or
another as all the other species before us didn't develop intelligence.
No intelligent dinosaurs, no intelligent birds, no intelligent insects.
Apes probably have intelligence in greater measure than cats, etc,
because the cat only needs to know how to claw something. The apes have
to invent claws and use them, and then invent other devices to use in
order to keep up with the specialised types.
A cat with a brain the size of a human would be less quick to the prey
and less singleminded in a fight compared to a cat with a cat-sized
brain. Intelligence is at a lower premium and so brain size is
sufficient for the cats limited repetoire of behaviours. For the ape,
there is no upper limit and the brighter you are, the wider the options
for survival or competition, not only with the other species but within
your own pack.

assistant: s
Indeed, and what's more, the sun will stop travelling across the sky at
the moment that this takes place.
Of course, this is true of the sun at every other point as well, we're
the ones moving. The planets are also always aligned, not counting
Pluto, according to the orbital plane.
There is some sort of event in the future, I forget when exactly, when
Jupiter, Mars, and Saturn are all in positions lined up away from the
sun w.r.t. earth. At this point, obviously their gravitational pull on
us adds up to a moderately large tug, and this can be translated into
geological events like earthquakes, for reasons below.
In ancient times, an ice age had just retreated and quite a lot of the
surface of the earth was adjusting to new positions being as the weight
of the ice on them had been removed. When planets lined up in this way,
their added pull can often trigger an earthquake which up to that point
hadn't quite got enough pressure to overcome the reluctance of the rocks
to move about.
Ancient astronomers spotted this trend and drew empirical conclusions
that the alignments were the cause, rather than the trigger. These days,
earthquakes are far less common and the alignment will probably have no
effect at all. However, "ancient wisdom" is still popular and no doubt
will help to sell newspapers and paperbacks dealing with the subject.
Stressed point: the earthquakes would happen anyway, it is just that a
trigger causes the beginning of the quake. Quakes are not manifestations
of the celestial gods meeting up at night.

assistant: Nope. He's suggesting that the new force, like gravity, acts with a weak
force. Gravity between you and someone else is negligeable. Gravity
between earth and moon is sufficiently powerful to be seen to act.
That's why is is called the weak force AFAIR.
So, this new force is so miniscule that galaxy to galaxy interractions
and time periods of billions of years are required to show it's effects.
It's a plausible theory, I suppose.

The refractive index is a constant which compares the behaviour at the
interface between mediums. It is a ratio of the sines of the angles to
the normal a beam of light makes. A mirror has an index of 1. The index
has to do with an impedance transformation, a characteristic of the
differing electromagnetic properties, and for which the speed of light
constant depends on the material. For example in a strong magnetic field
the polarization of a beam of light can be rotated (Zeeman) or alter the
speed of light (Delbrueck).

assistant: Arnold G. Gill said the following to MIKE ROSS on the subject of
Are atoms expanding? (25 Mar 98  10:06:50)
 [. . .]
I don't deny the mountain is held together by electronic forces but what
is the overall dominant attraction on that mountain? Common knowledge
would have it's the Earth's gravity which is pulling the mountain down.
However, from the gravity viewpoint, and because the mountain's atoms
are in fact mainly empty space, isn't it really any one of its
individual atoms that is orbiting the Sun regardless of the forces
responsible their chemical arrangement?
Of course the sum vector of their masses is what contributes to the
Earth's total gravity but all their mass being in the tiny nucleus, they
hardly gravitate with one another when compared to the Sun's influence
on each individual atom.
This is the analogy I was trying to express on how the cosmological
influences the subatomic. I completely agree that the atomic forces are
the greater in a direct local contact but they are the weaker of the
influence in the cosmological scale. Perhaps the parallel with the
analogy is tenuous, partly because it being somewhat philosophical.
I'm not trying to dismiss your explanation. This really is an enjoyable
discussion, only I'm almost certain I understand the basic principle and
the answer, from you and others, studies, text books etc, doesn't quite
feel satisfying somehow. I wish someone would set me straight on this.

nitpick:
Simulations show it would pretty much all rain out by the time a few years
had passed.  But a few years without an agricultural growing season would be
quite enough to destroy our civilization.  Our reserve stocks of food,
worldwide, have an exhaustion time measured in weeks.

Write your reply.

assistant: You're essentially describing classic Steady-State theory.  It was very
popular for a while, but the evidence in favor of the Big Bang seems
overwhelming these days.
1.  The cosmological red shift shows the Universe is expanding.  Extrapolate
back and it all comes to a point 10-20 billion years ago.
2.  Olbers's Paradox.  If the Universe is infinitely old, or just orders of
magnitude older than 10-20 billion years, the sky should be wall-to-wall
starlight, about as bright as the Sun, and we should all be cooked.  Light
falls off by an inverse-square law; area of a sphere increases as the square
of radius.  So for each concentric shell an equal amount of light is added.
It would be infinite in total except that the stars block some of it; they
"tile" the sky completely.  The only way out is if the Universe is too young
for most of the light to have gotten here yet.
3.  The cosmic microwave background is best explained as the thermal noise
from the Big Bang.  Efforts to extrapolate it from background starlight and
other Steady-State type mechanisms all fail on various qualities of the
radiation.
4.  The distribution of elements points to a young Universe.  The major
process out there is the fusion of hydrogen to helium in stars; yet the
Universe is still mostly hydrogen.  Models of Big Bang nucleosynthesis give
very close fits to what we observe.
5.  "Continuous creation" just isn't observed.  The tension in completely
empty space does not seem to create hydrogen atoms as Hoyle wanted, or quarks
as in your model.  But as of today, all models ever proposed for this are
essentially untestable.  Hoyle and Bondi had about one hydrogen atom being
created per cubic meter.  That's just too low to observe, and perhaps always
will be.  And a theory that can't be falsified by the same token can't be
verified.

assistant: Etc.
Not a bad model, but in fact very early religious texts _do_ often deal with
things that are "impractical."  Religion has been "explained" as imitative
agricultural ritual mistaken for propositions (by Frazer); distorted tales of
early heroes (by Euhemerus); priestly conspiracy to control people (by the
philosophers of the Enlightenment); ritual dealing with guilt traced back to
an early murder (by Freud); etc., etc.  The problem is that it seems to
persist among people who "know better."  Of course I have an axe to grind
when it comes to this subject; I'm a born-again Christian.  But everyone has
one worldview or another they want to back up.
And whether a particular religious idea "came from" a particular circumstance
or not does nothing to advance the inquiry into whether there really is
something besides Nature or not.  If you're sure from the start that
religious ideation is all wrong, you naturally have to come up with a
naturalistic explanation for it.  But if it's right, that also explains why
religions exist.
Estimates collected by Bok and Bok ("The Milky Way," 1981) cluster around 300
billion.
But your estimates of colonization time are roughly correct.  Simulations by
Hart (1975) and Jones (1978) indicate the whole galaxy could be colonized in
1-5 million years.  The fact that it hasn't been is then used by people like
Hart to argue that there must be no other intelligent species in the galaxy.
But that doesn't necessarily follow.  There could be something preventing
colonization -- technical problems we don't know about yet, or (the view I
favor) a galactic agreement to suppress colonizing civilizations because
they're dangerous to everybody around them.

assistant: It shows nothing of the kind.  You assume that colonization can take place in
a vacuum; that nothing is done to oppose it.  It could be that many
civilizations have colonized small areas and have buffer zones between
empires, and we're in a buffer zone.  That's why some deer are safe from
wolves -- wolf packs stay away from neutral zones.  Or the galaxy could be
full of enlightened types who won't allow a developing planet to be touched
(Ball's 1973 "Zoo Hypothesis).  Or it could be the explanation I favor --
that colonizing civilizations are suppressed because they're a danger to
everybody around them.

century and show that an old Universe should have a sky full of stars --
every path in every direction eventually ends at the surface of a star.  The
microwave background is the echo of the Big Bang.  It ain't starlight.
I don't.  Neither do most of the astrophysicists who worked with the COBE
data.
Look again.  There is no "age crisis."  The globular clusters are younger
than they thought.  Why don't these results penetrate to a public supposedly
interested in this stuff?
Galactic clusters would all have separated if it weren't for Dark Matter.
The Dark Matter is there.  No one working in the field doubts it.  (Also,
galactic rotation profiles wouldn't be flat if there were no dark matter, a
point first noticed in 1974).
