If we somehow managed to build millions of spaceships capable of traveling at 40% the speed of light, and we had an unlimited time span to explore (or a very long time, for example, about 100,000,000,000,000 years) involving billions of people, and stopped to colonize every other planet discovered, how long could it take to fully explore the entire Milky Way galaxy?

Galaxy is 120,000 light years in diameter.

120,000/0.4 = 300,000 years to cross it. If we go out in all directions from Earth we will conquer the universe in less time than 300,000 years.

If each ship wants to minimize the time it spends in deep space, going to the nearest neighbor, stopping to colonize, and building enough industry to build more ships, it will take many millions of years. If they stop long enough to fill up the planet before building more ships, it will take over a billion years.

But if you don't care about having your people in cold sleep/virtual suspension/whatever for vast times, then you'll send some of those millions of ships straight to the edge, and you'll get everything done in less than 300,000 years.

>> No.5060505

Now for something different:

You build a giant particle accelerator and create wormhole pair, each end held open by a thin nanoshell using the casimir effect maintain negative energy inside the shell.

You attach an engine to the wormhole, and accelerate it using propellant you feed into the wormhole. Because the rocket equation is no broken, you can get really fucking fast.

But to top it off, you make these wormhole starships bigger than they need to be. Big enough... to shove other wmaller wormholes through them. So you have a 99.9% lightspeed wormhole ship making a beeline for the edge of the galaxy, and every time it comes near enough to some other stars it spits out a another wormhole ship.

Meanwhile, back at home, your accelerator is working overtime building wormholes and feeding them into the mother ship. Each time one of these wormholes reaches a new planet, it's colonization time. Your home planet is now the nexus of a giant intergalactic highway.

It is not feasible to send people on spaceships to colonize the universe. It'd be easier to send unmanned factory ships to worlds we wish to colonize and have them build the humans right there. People are either uploaded to the ship beforehand or beamed there when it arrives. Bodies could be customized to fit the planet, or the factory could come equipped with terraforming capability.

Are you suggesting human teleportation? I believe most people would say human teleportation is not feasible. I also believe we will have mapped out much (if not all) of the Milky Way before mass colonization, to see how many star systems there are, how many planets there are, and how many planets are best for human habitation, although we might even end up colonizing worlds that are not entirely fit for humans (such as Venus).

>>5063257
Except that that doesn't describe Mass Effect at all. Mass Effect allows for faster than light travel across the entire galaxy over the course of a single day, not all the Milky Way's planets have been colonized, explored, or even discovered, habitable planets are very rare, there are other intelligent humanoid species easily communicating and even sexually interacting with each other, most of which are thousands of years more advanced and older than humans, and all of it takes place within less than two centuries from present day.

So wait, let me get this straight.

science fiction threads belong in /tv/ /tg/ /v/,
college advice threads belong in /adv/,
programming threads belong in /g/,
paranormal and conspiracy theory threads belong in /x/,
biology threads belong in /an/,
sociology threads belong in /soc/,
philosophy, psychology, and religion threads belong in /lit/,
politics and economics threads belong in /pol/,
infantile cartoon images belong in /a/ and /co/,
engineering threads belong in /hm/,
and homework threads aren't allowed anywhere on 4chan.

So what the fuck is there to discuss on /sci/?

I think what he means is that people are just coming off of playing Mass Effect 3 and are all excited about space exploration and crap. Not surprising seeing as that if was such a success.

But I'd have to agree. /sci/ has become a place to discuss more science fiction than fact, this thread included.

True. If anyone has any questions regarding science or math, they can't really consult /sci/ without being accused of asking for help on their homework.

High school level can be seen as too easy, anything below that is considered trolling, anything above that (such as postgrad math) can be seen as too hard to answer by /sci/.

Any questions regarding science or math can be directed at any number of web sites, such as Google, Wikipedia, Wolfram Alpha, Khan Academy, Physics Forums, Yahoo! Answers, WikiAnswers, ChaCha Answers, etc.
