Warp Drives Feasible in our life-time

Not to mention that the analogy to Magellan demonstrates a complete lack of information in the comparison. For example it ignores that Magellan wasn't hauling his own atmosphere along and he made quite a few stops along the way.
On that point, the atmosphere isn't a big deal, we've done that (like in a space station). And we've become quite good at preserving food, not to mention the possibility of growing some food on the way (also helps with the limited oxygen issue), so I don't think not being able to resupply is a big issue either. Might have to deal with some psychological issues from being stuck in a relatively small space for so long though (I do believe NASA has been investigating this already in aims of a manned mission to Mars), and if we're only talking a 10-meter bubble you can't really send a large group of people, making colonization of other planets difficult. At the very least we could send probes and rovers to investigate the planet, which would still be very interesting (especially if we found life of any kind).

What exactly do you think that they do on the space station to provide atmosphere?

Ok. So how many pounds of preserved food and water do you need for a single person for a 4 year trip? Presumably you do plan for them to come back?

How much volume does it take to store enough food/water for one person for 40 years? Why 40 you ask? Because even though on earth the voyage takes 2 years the time in the vehicle, per the article, still takes 20 years. One way. What about a bed? And entertainment? And backups to the engineering systems? And scientific equipment? Now once you have all of the computed how much more fuel does it take to move all of that?

Yes that fantasy is wonderful. But in the real world it costs real money. Do you know how expensive exotic matter is? Check out this link http://www.codeproject.com/script/Forums/Edit.aspx?fid=1159&select=4369404&floc=/Lounge.aspx&action=r[^] So are you willing to give up 90% of your income for the rest of your life to allow one probe to go to a star? Are you willing to make your family, friends and your children give up 90% of their income for the rest of their lives to to that?

There was a time when people thought that it was impossible to cross the Atlantic ocean because a ship would need more coal than it could carry.

There was a time when people were certain that it was possible to convert lead into gold also. But, the fact that history has successes doesn't alter the fact that history is full of far more failures. And it certainly doesn't alter the fact that exotic matter in the quantities referred to in the article is not even close to being feasible now and there is no current evidence that suggests it will ever be feasible.

The Eagleworks team has discovered that the energy requirements are much lower than previously thought.

Computers have been intelligent for a long time now. It just so happens that the program writers are about as effective as a room full of monkeys trying to crank out a copy of Hamlet.
This is even more a fantasy than I originally supposed. Per the article time on the vessel remains relativistic. Thus the 2 years one way mentioned in the article repesents 20 years on board the ship. Or 40 years for a round trip voyage. So 40 years of food, 40 years of water, 40 years of very efficient waste disposal, 40 years of mechanical maintenance. And enough exotic fuel to push it there and back - and I suggest you might want to check the cost of that. http://www.wisegeek.com/what-is-the-most-expensive-substance-in-the-world.htm[^] ... and 40 years of dealing with various human psychology. There are probably people who are willing to volunteer for such a journey but there are far fewer capable of doing it with a small group. Note that the same applies to a unmanned probe except that the chance for self repairs are less. And what about rocks along the way? Might seem trivial but for a vessel traveling at 10c the occupants will NOT be able to use any known detection methodologies. So either they must shield or absorb all collisions - all VERY high kinetic collisions. What technology is going to do that?

You do of course realize how many other theories also existed which are now not considered valid? Do you think that there are more that prove valid or more that prove invalid?

I know, i know, but the only way to prove them valid or not is by experimentation or direct observation, and i believe there have been far more theories that have proven invalid over time than the ones that have proved valid.

Dr. White and his colleagues don't just believe a real life warp drive is theoretically possible; they've already started the work to create one.Man, that's commitment! But, if you don't have a theory on how it would work, how can you come up with a reasonable fuel estimate needed to get it to work?! Whoops, I skipped the word "just" the first time I read it. Funny how one word can completely change the meaning. Personally, I'd replace "don't just" with "totally" and ";" to "," so you don't just confuse us slower folk. (Funny how you can remove "just" from that statement and not really change its meaning.)

They have to store it somewhere. It's not like a space station has a hose running down to a suitable level of the atmosphere to pull in air, nor do they get resupplied daily. And, according to this[^] most of the oxygen is made from water, which incidentally they will already need large amounts of.

I'm sure an organization like NASA has either already figured it out, or will before such a trip would be made made (don't forget, they have been investigating the possibility of a manned mission to Mars, the conditions wouldn't be that different in this regard). Also, most things beyond food can be recycled (including urine into water).

From the article:
Quote:
The time will be the same in the spaceship and on Earth
It in fact states that it will take the same time to the people on the ship (as it should, their velocity is 0). Still only 4 years (+ time spent at destination).
jschell wrote:

If they stay in orbit? About 1000 kg of exotic matter for a round trip, and a small amount of fuel to maintain orbit. It may not be stated in this article, but massive amounts of energy are only needed to create the bubble, not to maintain it (energy may be necessary to break or leave the bubble though). If they land, add enough to do something like what we used on the moon. It'll need more fuel to make up for stronger gravity, but not everything has to be brought back.

Good questions. You should really read up on them as I am not the one to explain it. Nor is this the proper forum. But I doubt in your reading you will ever see anything refer to it as magical :)

I majored in Physics, and I've done a shipload of science writing (for real science projects) since. This isn't science. It's "If we find a unicorn, we can ask it to make a magical bubble that will carry us to Neverland". At best, it's a masturbatory chain of "Oh, if a substance with these powers can exist, then we'll be able to to this with it -- and if we can do this with it, then we should be able to do that with it -- and if we can do that with it, we should be able to... etc.", with every step taking us further and further away from reality, and all based on a single premise that hasn't even come close to being proven. The thing is that substances that contain magical powers don't exist (I know that the word "magic" is never used -- do you think they want to give the game away?), which is why writers have to invent stuff like dilithium crystals, i.e. magic rocks, to power starships. Next, they'll be saying that you can power starships with a few grams of gold formed into a toroid.

Ahhh.. You do realize they used a generic term "Exotic Material" which is like saying "rare" material. Honestly how are you so certain that it does not exist? Have you read all of the references? In some cases when talking about it ("exotic material"), the scientists are referring to anti-matter... Which does exist and (by creating it).

Just to be clear - I was commenting on the nature of the 'gee whiz' attitude in the article and not on the scientific benefit of the research (from which the article was postulating.) But based on your comment I am glad you are not - because as I showed the cost of what the article presented is so astronomical to be nothing but fantasy.

Seems to me that most of the article is devoted specifically to how the drive could be used, and specifically mentions places that one might go to with it. Versus for example discussing the raminfications of the science itself.
