Alan has requested that I post this. I'm not editting it for quotes, too many. Deal with it. LOL

Hi Kojikun
I had a look at that thread again. I'm very impressed to see that the
tone of discussion has moved above insults. Therefore I've written a
reply

TO BE POSTED ON SDN - Orionarm.org thread
----------------------------------------
Hi everyone. My apologies for the delay in replying. I will just
respond to your queries here

Except that wormholes and the breed of warp drive discussed here don't
make you actually go FTL; they cheat, and you never leave your own
light

Alan:
it is not "cheating", simply bending space-time, as allowed in general
relaticvity. Objects passing through the WH still dont go FTL relative
to an external observer

Is Nanotechnology possible? Of course it is. It violates no base laws.
However, OA, like many other places, gleefully ignores the inherent
weaknesses of nanotech.
---------------------
Alan:
No-one knows exactly how effective nano will be. I do think it will be
more effectinve then you and Mike and others on this forum believe.
But
as to how much more effective, i personal;ly don't know. In OA we
assume very effective, but it is still an assumption (albeit one based
up by arguments on the Foresight Institute)
---------------------
SirNitram
I will go on, at length, in the next reply.

<--
tell all your guys with problems with nano to have a good read of that
one And for them to read the associated links.
Assembler nanos and medical nanos are very different; the so-called
Osiris Treatment(I am sure Alan knows what I refer to, as he references
the enjoyable GURPS Ultratech books on his site, IIRC)
---------------------
Alan:
GURPS Biotech is cool too

---------------------
SirNitram
is one of the many possibilities created by nanotech. However, I object
to the other presentations of nanotech.
Nanoswarms are the most offensive; how could they be a danger? Detonate
one atomic warhead in front of the swarm; the surface area of a nano is
such that it can't handle heat as well as a macroscopic construction.
It'll fry.
---------------------
Alan:
sure. Assuming the swarm is still localised. But the Replicators
could
be widely dispersed. A nuke is local. Sure you could have millions of
nukes, but you still wont get them all.
And what if the replicators are infecting a populated area. You'll
get
rid of the swarm, but also kill everyone there anyway (hence concept
of
defensive or "Blue Goo").
---------------------
SirNitram
Nanoassemblers are theoretically possible, but this works out much
better on paper than in reality. A nanoassembler must go atom-by-atom.
Anyone whose got a good grasp of mathematics should realize that going
atom by atom as opposed to rapidly working on large chunks will be
ridiculously slow.
---------------------
Alan:
If you only have ONE assembler with only ONE manipulator
arm, sure.
But
what if you have trillions? Or quadrillions? Or more?
Let us say we have a large and complex assembler (a compound nanite,
essentially, not microscopic) used for construction. It might have
10^6
positional devices per assembler head, 10^6 heads per subhead, 10^6
subheads per system, and run at an optimal speed of 10^6 operations per
second, assembling 10^24 building blocks per second.
So while indivitual nanites or manipulator arms may be tiny,
collectively their huge numbers compensate, with each manipulator
arm
having an optimal speed of 10^6 (i admit it would be slower in
non-optimal conditions)
---------------------
SirNitram
Will a nanoassembler be useful? In medicine, it will likely introduce
revolutionary new ways to treat long term conditions. But imagining
it's
some godtech to punch out cars and such in short term is nothing but
fantasy.

<-- the case for pico is not yet as strong as for nano, but it does not
vilate causality the way that warp drive or hyperspace FTL does
SirNitram
I wish I knew what causes Picotech to be rated compared to FTL travel.
Shouldn't it be compared to, say, the complex mass altering technology
of Star Wars, as both are mathematically possible, but we can't see how
to make them? I digress.
---------------------
Alan:
Good point. I read an essay some years back where some guy explained a
Trek replicator in terms of electron beams or something (don't quote
me,
i forget the details)
---------------------
SirNitram
Picotech is presented as matter 'sculpting'. Truth be told, there is no
real problem here. To a small degree, we have this now, though it's
clumsy and involves ramming atoms into each other. It is the outcomes
that ultimately become realistic. I'll just touch on the most
ludicrous.
Drive Sails are a nasty culprit, noted as under picotech. When other
sci-fi get along nicely with solar sails, a Drive Sail is a reationless
drive. I shouldn't have to go on at length at why a reactionless drive
is silly; it's something for nothing.
---------------------
Alan:
See
http://www.grc.nasa.gov/WWW/bpp/TM-107289.htm
I agree this is very speculative technology. If OA was to be Ultra
Hard
it wouldnt have any reactionless drive
---------------------
SirNitram
Neutronium constructed for GUT drives and other uses on starships
deserves a few moments. We at SDnet have heard every argument about
Neutronium possible, thanks to Trekkies who get pissy about the
neutronium components of SW armor. Needless to say, large chunks of
it(The Neutronium Cores mentioned in the historical files) are
inherently dangerous; how does OA, with no artifical/contragravity
survive having these onboard?
---------------------
Alan:
I agree it is handwavium

Oy vey. I suppose I should point out this is mildly insulting; we have
a
page which goes to great lengths to tell us how realistic it is, then
this. I want to make something clear: If OA advertised itself as merely
Sci-Fi, I would have no objections at all. It is, fundamentally, a well
craft universe with many unique and interesting ideas.
The rub comes from the incessant message that 'We're better, '

Alan:
We do not say "we are BETTER" Please show me which page on the site
says "we are better" and I will correct it right away!

Alan:
SirNitram, here is the reply to critics of nanotechnology in OA
(copied from
http://www.orionsarm.com/intro/answerin ... iamandnano )
-----
Q. What about articles in Scientific American refuting the possibility
of assembler-type nanotechnology?
A. As for whether or not full drexlerian nano, including working
assemblers, is possible, so far there have been no serious
refutations of the work of Dr Drexler and his co-workers. An attempt
to
debunk nanotech in Scientific American was
answered with a powerful reply, which caused the editors of Scientific
American to ultimately back down. Here are the links to the reponses
to
both of the Sci Am articles from Sept. 2001:
http://www.imm.org/SciAmDebate2/whitesides.html
http://www.imm.org/SciAmDebate2/smalley.html
Here is the entire history of responses and back and forth between
Foresight and Scientific American back in 1996:
http://www.foresight.org/SciAmDebate/Sc ... w.html#TOC
This also includes some interesting references to some apparent
inconsistencies in Scientific American's positions versus its
advertising and blurbs in other articles.
On the Foresight Institute website,
http://www.foresight.org/ one will
be able to find a plethora of articles and info on nanotech including
the online versions of both Engines of Creation and Unbounding the
Future (arguments w/o math) and Nanomedicine Vol 1 (arguments and info
w/ math). It also provides the option of purchasing Nanosystems online
if you want the relevant arguments with all the math.)
-----
You and Mike are welcome to refute their arguments if you can.
---------------------
SirNitram
and completely unfounded leaps in technology; the GUT drive is a good
example.
Hard Sci-Fi.. The real stuff.. is ideally set close to the future.
---------------------
Alan:
This is a problem of different words used to mean exactly the same
thing. I define what you call Hard Sci-Fi as Ultra Hard Science
Fiction. I agree, OA is not Ultra Hard, and is not intelnded to be.
Some examples of UltraHard SF by my term, or Hard Sci Fi by your term,
might be "Permutation City" by Egan, "Fountains of Paradise" and "The
Ghost from the Grand Banks" by Clarke, the Red, Green and Blue Mars
Trilogy of Kim Stanley Robinson, "Islands in the Net" by Sterling,
GURPS
Transhuman Space roleplaying game, and the Ad Astra Universe of Richard
Baker and David Dye.
I reiterate, OA does not claim to Hard Science of this category!!!!!!!
---------------------
SirNitram
As OA shows us, the further into the future, the more addle-brained
some
of the assumptions from reality will become. This isn't necessarily
bad(The Culture has almost no beleivable tech, but it's wonderful fun),
but you shouldn't pass yourself off as 'hard'.
---------------------
Alan:
Yes, this is a problem with definition, and we are using the same term
to describe two different things. John W Campbell used the term
differently again. And I once saw a page where Star Trek was described
as "hard!"
By hard SF I mean a universe where the following DOES NOT occur
o Small Space ships wheel and bank in a vacuum
o Large Space ships fly in 2-dimensions like naval vessels
o a civilization with godtech spaceships but still no
cloning/gengineering (SW Ep.2)
o a civilization with godtech spaceships but still everyone only lives
3
score years and ten
o a civilization with godtech spaceships but still people are all
baseline humanoids
o Many humanoid alien races (look at how evolution works on Earth)
o Every alien planet the protagonists land on looks like today's Earth
(just look around our solar system - Earth type worlds are likely to be
very rare)
o Barren world with breathable atmosphere (oxygen is a highly reactive
gas - a lifeless world woiuyld have a reducing atmosphere)
o There is an attempt at explaining things (not treknobabble),
regardless of how iffy some today might find that explanation
and maybe (although this is debatable, since for all we know the
universe is acausal)
o Causality violations (FTL)
---------------------
SirNitram
Finally, as a sci-fi author, I'm insulted to think people insist we
can't craft epic tales of science fiction from what we've got. I have
real trouble with people who tell me what I can and can't do.
---------------------
Alan:
SirNitram, neither I nor anyone else on OA are telling you what to do,
nor would we ever wish to!!! There is room for both soft sci fi,
science fantasy (which George Lucas specifically acknowledges SW is),
more realistic hard SF,as well as ultra hard SF (which OA is not), and
everything in between
To reiterate, we're NOT saying OA is *better* than SW. SW is one
univese, OA is another, why all the fuss on SDN? Me, enjoyed all the
SW movies (except for Phantom Menace, which annoyed me, maybe cos of
Jar
Jar Binks and the bumbling
droid army of the Trade Federation) So i'm not dissing SW, and if
there
is anywhere on the site we seem to be, please let me
know, so i can fix it!
Who OA *does* address itself to are those people who want something
more
plausible than baseline human beings in sillytech/godtech (whichever

spaceships

Or nanotech given newer and cooler names and abilities. Assembly from

Alan:
Actually advantages are magnified - the smaller a thing is, the faster

SirNitram
Understanding the physics on that level is one thing, but the absurd
idea that it will transfer up the ranks so you can make GUT drives?
Quote:
also, for the person who thought OA femtotech disabling SW/ST shields
is
silly (sorry, didnt note the name - was skimming through) How do your
shields work? I assume they are an electromagentic of some sort? Or -
never mind handwavium - are they just nothing but magicfantasyium? "Now
i have a force field - you cant get through, you cant interact with
it."
Well, assuming they ARE some sort of field effect, they would most
likely be electromagnetic, because that, and gravity, are the only
forces known that work at a distance. Even if they are (much handwavium
here, and any reference in your canon?) some sort of quantum field,
femtotech works on the quantum level. Just as nanotech manipulates
atmoms with precision, so femtotech manipulates quarks, etc. Anything
on
the subatomic particle level you have, the archailects can use anyway
they want
SirNitram
Assuming, blindly, the effects can pass through. How does an
Archailect's manipulation work? Tiny 'bots?
---------------------
Alan:
no, it would be femtotech and smaller. Yes, i acknowledge it is
handwavium
---------------------
SirNitram
Gonna go 'pfft' on the shield. I don't see what other means might be
availiable, if you are staying somewhere within the bounds of reality.
A
Field from a Culture vessel could try pressing against it and sneaking
through a fissue, but you ain't the Culture.
Scale doesn't matter. Shields have no real world link; they're a
Godtech, shapable field around a starship, which can have small
sections
raised and lowered. They absorb and re-radiate energy over their
surface(Hence the glow). If you can't get through the shield by brute
force(And it's alot of brute force; an ISD has a power source literally
millions of times more efficient and potent than a GUT Neutronium
core),
you simply can't interact with the stuff inside.
---------------------
Alan:
well if you really have godtech shields then you have a good point.
The
archailects also have godtech, and you have godtech. However, even a
basic transapient can outsmart an ordinary sapient, in the same way a
human is msmarter than an animal. The OA Civilization works through
the
archailects manipulating lower sophonts as easily as a gardener growing
plants. This is what you guys miss - it is not even a tech difference
-
sure - you have godtech. It is a brain difference. Look who is master
of the Earth now. It is us, humans. Why? Aniamls are can run faster,
are stronger, have bigger teeth and claws, etc etc. But man wins.
Why. Because we have a superior intelligence. This is exactly how OA
works. It doesnt matter how much more powerful your Death Stars,
Godtech shields etc are. The fact is that they are all contriolled by
ordinary sapients. A being of human intelligence isnt even a microbe
in
the OA toposphic hierarchy. This is the essential point that the
munchkin "my ship is bigger than yours" arguments miss
---------------------
SirNitram
As to a
Orion's Arm galaxy vs. the Galactic Empire? The Empire's going
to squish the Milky Way like a freight train. The Galaxy Gun.
---------------------
Alan:
see my above comment

----------------------------------------------------------------------------
kojikun
Nitram: I emailed Alan the same arguement about nanotech. Basically it
came out to take a few days to weeks to assemble a piece of toast even
with a trillion nanites placing a trillion atoms per second.
---------------------
Alan:
As mentioned above, because there are quadrillions of assemblers or
manipulation arms involved, actual speed would be a lot faster.

Alan: it is very odd that you use this argument against warp drives but
not wormholes. Why the duplicity?
---------------------
Alan:
Because wormholes cannot be used to make a time machine. As Matt
Visser
has shown, any attempt to violate causality by using two wormhole
mouths
to make a time machine (Stephen Baxter describes something similar in
his book TIme-Like Infinity - part of the Xeelee Universe) results in
the mouths being swamped by virtual particles and the WH's collapsing
---------------------
Kuroneko
For that matter, why is Minkowski spacetime assumed at all? General
relativity explicitly denies this, and both warp bubbles and wormholes
exploit this fact. A ship can travel along a timelike curve (i.e.,
subluminally) and still be traveling FTL with respect to the proper
coordinates of a distant observer. There are no ineherent causality
violations in this.
---------------------
Alan:
As long as the ship is in its warp buble or hyperspace there is no
prtoblem. But when it emerges to interact with the rest of the
universe, you get time travel paradoxes. The following essays (already
mentioned) indicate why there are causalty paradoxes when an FTL ship
re-emerges in "normal space"

Guys, we've thought long and hard in designing OA. We've had our
sceptics and critics, including on occasion myself! Over the years we
have had lots of people asking the sort of questions and raising the
sort of objections you SDN OA critics have. You are welcome to send me
a list of objections to OA that are NOT addressed here, or on
http://www.orionsarm.com/intro/answering_criticism.html or on
http://www.orionsarm.com/intro/answering_criticism.html , and I'll
answer all of them for you
btw, there have been a couple of decent objections raised on your forum
these are
o our hard-soft science scale is arbitrary - REPLY - sure it is, any
human formulation is arbitary to some extent. So i WILL
modify that page to address this concern, also add the relevant
disclaimers - this is purely something written for OA, should
not be taken as an absolute
o we are arrogant and full of ourselves, think we are better than
everyone else, etc - REPLY - please cite the pages where we are, i will
modify them, if i feel these concerns are valid
o we claim to be hard science but we arent - REPLY - The term "Hard
Science" is relative. We do not claim to "Hard Science" as defined by
SirNitram (Ultra Hard Science). We are "Hard Science" relative to ST,
SW, B5, Farscape, etc
o someone said us saying the highest AI Gods are "as high as you can
go"
is ridiculous. - REPLY - Actually, this is a very good point. I
*will*
modify the archailect pages when i next revise them, to make it more
open-ended. thank you
