Space must be a testbed of good technology, and brings people together. Not this dirty idea what destroying planets.
There is a ton of good technology in a death star, it's just used for destructive purposes. A death star could solve pretty much all of the problems facing our world, if we used it correctly. Consider this;
- The energy needed to destroy a planet is immense, calculated by some to be in the range of 2e32 joules (see
http://www.stardestroyer.net/Empire/Tech/Beam/DeathStar.html. Even if the Death Star's handwavium, er, "hypermatter" reactor can only produce a fraction of this in continuous operation, it'll still be able to power global civilisation
several trillion times over. Even a single Star Destroyer would be overkill for suppling the global grid. Even low grade power generation technology used in Star Wars could provide us with abundant clean energy.
- Space travel in Star Wars is extremely casual. You've got a superpowerful spaceship, that carries a large number of smaller yet still extremely impressive spaceships; according to
this page, over 3000 Imperial Shuttles. And looking at
this page, we can see some of the vehicle's capabilities;
- 20 passengers or 80 metric tons cargo.
- 2 months consumables.
- 1400 G acceleration.
In other words, you can send a crew of astronauts and a sizable payload on a day trip to Pluto, and have them do science there for several weeks. And that isn't even considering the hyperdive; Star Wars FTL speeds are not quite well pinned down, but they can travel galactic distances in a matter of days or weeks. Not only could we greatly expand our knowledge of the solar system, but our knowledge of other, nearby solar systems as well. It would be an all-new age of discovery. And that isn't even considering the plethora of handwavium, er, advanced sensors that the Death Star and its subsidiary vessels would carry.
- The Death Star is so large that you could probably turn it into a space colony capable of supporting billions, with the right effort. In addition to being able to find and colonise other planets, and use immense power to terraform uninhabitable ones, a sizable portion of the global population may be able to emigrate to the Death Star itself.
- The technology of Star Wars would bring numerous advances in materials science and other fields (medicine, computation, propulsion, manufacturing, and soforth). Even if it is not immediately possible to replicate Imperial wonders such as Durasteel, the Death Star itself could be an adequate repository of material; at an average density of 500 kg/m^3, the battlestation would have a mass nearly twice that of Enceladus. A tenth of a percent of the Death Star's mass could supply the equivalent of the current global steel production for over a hundred million years.
- Of course, all that armament would be handy for dispensing with the next Chelyabinsk object... or the next Chicxulub object...
Once you look past the "wizards and knights in space with lazors" thing and look at the (extremely geeky speculation on) the technological capabilities, the Star Wars galaxy shows its true nature as an extremely powerful Kardashev scale III civilisation.
If I would start a kickstarter project for an "Shuttle-derived Asteroid defense vessel", how many people would only laugh and how many would actually read the concept?
I think part of the problem is that jokes like this reduce the legitimacy, in the eyes of the community, of realistic, if ambitious, projects.
As Stephen Hawking said, based on the previous interactions between the more advanced and the less advanced civilizations, the prospect of us, meeting another much more advanced alien race and interact peacefully is worryingly slim.
That's an overly cliche view, though. Consider India; it has over a million people in its military, a military with modern equipment, aircraft carriers and nuclear weapons. India has a claim on North Sentinel Island, which is populated by the Sentinelese people; a population of perhaps 300, who reject contact with outsiders and are one of the last remaining uncontacted people on Earth. Their technology is stone-age.
India could roll over those islands with impunity, and conquer them without losing a single person. They could destroy every living thing there and reduce the landscape to rubble, but they don't. The idea that a technologically advanced party in a contact scenario would invariably act like conquistadores is, ultimately, absurd.
