Liking the thought.
Not long at all is my opinion.
Assuming we can get rid of personal interest, money and religion.
EDIT to add..we'd obviously have to execute everyone that said the word 'impossible' too. (you were talking feasibility, and not moralistically weren't you?)
If the whole planet pooled it's intellect, resources and so on, probably no more than five years...a fleet of thousands would come soon after.

With the current space launch systems it would take many decades and be ready for the scrapyard at the end of the building process.
A 200000 ton 300 metres long spaceship built from modules no more than 18x4.5x3.5 metres, hauled on a spaceshuttle that carries no more than 25 tons.
With russian rockets it get's better 2 to 3 times the cargo capacity, but it would still take decades.
EDIT:What is needed is a production facility in space, and I don't mean a space dock. I mean a plant with automated rolling cluster, metalworking systems and storage space for steel blooms, slabs and finished parts.
If that was in place, then the parts of the spaceship would not be constrained by the delivery system and the delivery system would just need to haul steel blooms or the occasional electronics into space.

Is it possible to create a material with a nao-weave that causes it to tighten or stiffen and possibly change composition in stages to accomplish this?Like armor that becomes stronger by pirating the energy of the projectile to initiate a chemical or physical change in the armor itself resulting in a stronger barrier and a conversion of damaging energy into protective energy?Any materials or whatever type of engineer may know if this is currently possibe or if it is on the table.
How about we say 240 batteries of rail guns and I will google George Bulls payload specs and we will triple them considering technological advances since he was murdered for his contributions to humanity,he knew his idea had to be brought into the mainstream but was forced by the powers that be to bring it out as a military application and when they realised the potential to launch cheaply into orbit they murdered him to stop him from spreading the technology.
Anyone know how much of a liftoff advantage would be gained by being far undergroung as opposed to using buoancy or the water as lift or pirated energy ?Pros and cons of both possibly,just ballpark numbers.
How about launching materials to grow or to manufacture nano-materials in space?Maybe steel blooms only at the beginning.
Any predictions of how technology "might"improve as we are building say over ten years--I mean some guesses on materials currently being researched and other energy concepts now in the R and D stage.
Go to Bing and enter--George bull cannon space payload weight--read the first site titled Gun Launch,read the first couple pages I dont know how to make a link ,if you do there is a wealth of info there ,including underwater related topics.
Sounds absolutely feasable .

The cost would be astronomical, the time would take so long.. but the most impossible part.. Having all major superpowers focussed on one major endeavour like this. It'd take something huge to unite powers like that.
Just ideas, i'll be honest i Hope i'm wrong.. but I don't think i am

The little insystem triangles have von Neumann-Einstein drives, the bigger ones with interstellar capability use Mach drives.
vE drives could go superluminal if they could fix the godawful control instability problems. Not that they're likely to. But it would be less expensive than a Mach drive, which is a big Swiss watch sort of thing in terms of complexity. Horribly expensive.

Are you a secret CIA spy who went rogue and now wants to free the world from their evil secrets?

There was a time when I too thought that we could build a spaceship so huge that we could save many humans from extinction. Then as things would have it, I found out that we don't need to build Star ships to save humanity. All we have to do is make public the secret technology that allows for instant teleportation to distant planets and other galaxies or universes.
A secret technology that combines wormhole creation with Star-gate portals that allow for moment throughout the universe and distant planets with no need for all the Enterprise type ships that go forth to go where no one has gone before. Those that have the secret technology have been using it for decades to populate off world colonies. Since it is currently used to move between planets and star systems, it is this technology that could save mankind from extinction.
It is this technology that renders world population control and all human population concerns null and void. With our ability to populate distant planets with small populations, we could save all of planet Earth should it become known that Earth was to be hit with an E.L.E. Anyway, building large space ships could still be built, but because of the lengthy time, money and materials needed to construct such a ship, it makes more sense to use the secret technology the elite will use to save themselves before the SHTF.
We only have to make them give it up because anyone who thinks that Obama is going to willingly reveal such secret technology is brain dead at best. A zombie at worst.
Thanks for the posting.
