Yep, the image is an illustration of the Michael from Footfall. Good book, if anyone wants a hard-scifi alien invasion story. Holds up really well, despite being written in the mid 1980's. Swap a couple things, like the "US best troops are in Europe to fend off Soviets" to "US best troops in middle east" and change the Shuttles to Starships, and well Hollywood I just gave you your next blockbuster.

Given how popular war documentaries are I have to disagree.

Instead of "lets listen to some classical music while I show you design sketches for a nuclear pulse propulsion space craft" it's "here is a mock up of the space battleship designed by project Orion that is propelled by nuclear weapons".

Tell people about the load and how many cities it can target with it's MIRV firing howitzers.

>enormous military budget
4.5% of GDP
half of which goes to NATO
another quarter goes to supporting contracts with alliances
1/6 to R&D
The rest to recruitment, maintainance, and black projects

Troll harder bro.

>I say we go to space as a classless global culture, or we dont go at all.
I say we go as awesome space imperialists.
Also SPACE BATTLESHIPS PROPELLED BY NUCLEAR EXPLOSIONS, fuck yeah!

However I must say that for all you who that space exploration will always be peaceful and cooperative I've got respect fully disagree. Give the type of payloads nuclear pulse propulsion can move about resource extraction from space becomes viable. It will likely be the dawn of a new age of imperialism, and I am quite comfortable with that.


1) Use nuclear pulse propulsion to lauch 100,000 tonne ship into orbit.

2) Park it near a 1 mile diameter nickle-iron and use the ship as a gravity tractor to alter its orbital path.

3) Use the propellent warheads on the rock to slow it into high orbit around Earth, by detonating the nukes off the surface, vaporizing a portion of it, provifing thrust for the braking maneuver.

4) $20 trillion dollars of ore. And no, it won't flood the market anymore than fining sedimentary basin full of BIFs on Earth would. You still have to mine it and process it, which will take awhile. Also you now have a crap load of building material already in orbit.

5) Deorbit the rock on your enemies for about 3 teratons of fun. It's a weapon and a source of profit at the same time, what more could you ask for? And if you just altered the things original orbit to make it earth crossing, that way it has a higher velocity and makes a bigger bang.

6)Profits!!!

So if I took a really really long infinitely strong piece of rope(in which sound ways travel below the speed of light) wrapped around a giant spool connected to a giant generator at the galaxy's center of mass and tied the other end to the center of mass of another galaxy could I harness the energy from the expansion of space as the galaxies slowly move farther apart?

Engineer here, since you can send and receive information to/from our universe could you tell us when we should open and close a nanoscopic trap door so that we may violate the second law of thermodynamics?
