uhh...no, see the diffrence is that Linux might have many local exploits that have not been found, but the structure of the OS makes it very hard for a remote exploit.
the sheild is just used to deflect debry as they move through the universe.
inertial dampeners can exist everywhere in the universe. their existence is not based on "special physics" since reletive to their location (inside the ship) the physics of GR hold.
your reasoning is tantamount to claiming that shocks in a car only work because they exist behind the frame and side panels.
inertial dampeners create a feild around the ship, and the frame of refrence for everything inside the ship is the space contained inside the feild. the propultion systems propel that entire frame of refrence so to the people inside the ship do not experience the momentum of their masses when accelerating and decelerating.
there is no law of physics that say it is impossable, and to be able to move swiftly through space, such a device will have to be created. until then, we will be limited to gradual acceleration and deceleration, but by the time we have the energy to move a large space craft at.5 c, we will have enough energy to perhaps make worm hole jump gates a plausable tool. in such a case, we coul se such devices up in key areas and travel throgh out the solar system would be very easy.
probably. but was Zubrin talking about the ion drives of today or the ion drives of the future?
today, I agree that it has almost no thrust, but because of the constant acceleration, the ion drive that we have out in space right now it the fastest man made machine ever made.
but if given enough on board power and the appropriate fuel load (one of the good things about the ion drive is that it does not need oxygen for propultion) we should be able to get a nice thrust out of it.
and even if that fails, if we went back to the orion project (the USAF Nuclear propeled rocket) then we could use that to move through space and get more propulsive endurence than chemical rockets with the same thrust and far less fuel.
I know the one being used now has almost no thrust, but I heard that if you increse the power sent to the drive via a nuclear reactor, you get a very good thrust from it.
also, on the topic of reactors, would the old Air Force experiment with a nuclear rocket be reproducable with a clean fussion reaction?
if we can get.5 c travel I will be happy. that means we will have entered into a type I civilization since the entire solar system is with in a few days travel and we can begin colonizing and exploiting it.
just think, all the heavy metals needed would be in the asteroid belt and it would only be an hour away,
if at some point we find a way to do half light speed travel, we would go anywhere in the solar system with the outer rim being a few days trip. in such a case, we would populate every place in the system and make a huge array of space stations for mining and such. then living in the Oort cloud would be no more difficult than living on a rock in the middle of the Pacific because there is a radar base there. supply ships come and go every week or so.
the problem is coming up with a propulsion system that will move that much mass at that speed with out running out of fuel quickly.
perhaps if we can figure out a way to expand space behind the ship and contract it in front, then we can use that to propel us and we would just have to manage the fusion generators in order to keep power to the equipment.
we cetainly do need a fronteer society, but would you be able to get anyone to go when they know that if there is a problem with a supply run (the odds of there being a problem on the trip is larger than one would like) then you are dead, unless we can find deep ground water and a cave system that we can excavate for the colony to live in while they bio-dome it and rappid trasit to the colony from earth.
I say, work on getting us into orbit faster, then work on getting a massive ion drive so that we can get the right amount of thrust in space and sustain it for the trip there and back. estimates are that a trip to mars in such a situation would take 6 weeks if you accelerate constantly with the thrust of a rocket half way and then decelerate equally.
all we need to do is perfect scram jet technology, then the cost of getting to orbit will be small. once that is accomplished, out high voltage ion drive run by a nuclear reactor can be turned on and the 30 pounds of fuel can be inserted into the drive. and off we go.
of course we will need something much more sustaining to get to Jupiter and such, but taking the same approach, Jupiter is only 9 moths away.
umm, no, ATT and MCI did not have local service before this.
the big problem is that the local phone companies had to give the competition leases on the lines that could not even pay for the mantinence of the lines. what sucks is that I am on Talk America, so if this holds, I might lose my service and get stuck with SBC.,....on the upside, this ruling will give the baby bells incentive to start expanding their DSL networks again.
ok, so, you did not recreate the conditions that these people claim to be needed for success and you use your failure to have the same outcome as a counter example?
that is the stupidest thing I have ever heard.
here...I am going to try to produce the same outcome....
*fills glass with water*....*places straw in water*...*blows into straw producing bubbles in the water*...*shakes glass at same time*....
hey, zero-point energy could become a reality if one day we have the ability capture it with a wire that is made up of particles smaller than the smallest subatomic particle and have a life time that is longer than a few pico seconds.
if you can scale this to a large amount of atoms, say, eventualy encompasing a 5 gallon drum of liquid, there will be so much exess heat generated that it will have to go some where.
the problem will be not destroying the medium (the liquid) in the proecess.
I asked some questions on physicsforums.com about string theory and how it is doing. that is simmilar to the answer I got from the moderator of the forum.

google will have a new service soon.
google encyclopedia....they look at the web and take the most comprehensive articles and give you those as a source for a serch term.
I am happily married and my 2 year old loves ST :-)
what channel?!?!
NOOOOO
that would destroy my star trek fix!!!!
Dish Network offers much more configurablity in their plans than Direct TV.
you do know that the lighter the coffie the more caffine there is right?

good point. I was not thinking about that.
actualy, in star trek, they have inertial dampeners. their sheild has nothing to do with it.

if you can travel at .5 c, and it takes light aproximatly 30 minutes or so to get the the asteroid belt, that makes it 1 hour at .5 light speed (.5 c)
what exactly was the problem with the ion drive?
I know the one being used now has almost no thrust, but I heard that if you increse the power sent to the drive via a nuclear reactor, you get a very good thrust from it.

that hs been my issue with power generation. we have not moved beyond what we did 200 years ago with mechanical transfer of energy.
they pulled it off in chain-reaction...all we need is a smart machinist :-)

nope, no fusion...those guys must be on crack.

you just never know.

I smell a conspericy.
I think that LJS caled up NASA and said that they will go nder if anounced on the 29th so they anounced on the 3rd of march

string theory has prodicted some stuff, and work is being done to predict other stuff from QT and GR.
