For anyone wondering what the real significance of this historic event is:
Rockets cost about 50-100 Million dollars
Propellant costs about 200,000 - 1 Million dollars
It currently costs about 2,500 dollar per pound of payload into LEO (Lower Earth Orbit) and SpaceX is the cheapest on the block
If you can reuse the rockets, this price can probably be brought down to one tenth of that (250 dollar per pound) which makes access to space tremendously cheap
Light pollution is the devil
And just to be clear, the reason I like space is because of what you said: no muslims in space.

There was a cosmos related thread, you know, before Molly and Vibe started playing Elite. Cba to dig it, started by Ninja Master Khorin methinks.
btw I recommend watching the whole thing, imo it's really tense.That'll be fixed soon enough.
Also I just want to mention there are also no guns in space (yet).

If you noticed there's 2 galaxies together at the bottom, they're called USNOA2 0750-07913885 and USNOA2 0750-07913859:Just rolls off the tongue, if I ever have kids I'll name them that.
Light polution is a bitch, I don't see even one star most of the time... Though there is an observatory higher up in the city, the have open doors night 2 nights a week and enterance is free, it's quite a trip,on a clear night, seeing Saturn and his rings just "standing" there so car away is a truly remarkable experience.
...but when looking at the big picture, they turn out to be their own galaxies. Astonishing.
The question of whether we are alone in the universe has little practical implications. Whether we are alone in the galaxy is a bit more interesting, and I'd be tempted to say we are probably not alone in the galaxy, still. Out of a few thousand, we already know of a couple planets with potential liquid water. There are a couple hundred billion star systems in the galaxy, more than one hundred billion planets.
Yep and it's why I'm convinced that there is some sort of intelligent life out there. (not saying we have been visited/contacted by aliens, I'm just saying it's most likely out there... Somewhere).
I find it much harder to believe that we are the only intelligent life out there and a big part of this is due to images taken by hubble telescope and pondering just how big existence really is.
Yes, but with the caveat: "with our current technology." Remember, a hundred years ago the mere idea of flying to the moon would have seemed completely bonkers.
Yes, but the problem is that the earth is relatively young. That intelligent life had billions in advance, they ought to be here by now. Look up Fermi Paradox. Somewhere has to be a filter.
Like I've mentioned before, I don't think the Fermi paradox is that big of a mystery. There is such a narrow eye of a needle that has to be threaded for a technologically advanced civilization to arise that it's not that shocking to me we haven't seen "anyone else" out there. Life? Life almost certainly exists somewhere else, probably even relatively close to Earth, but that's a far cry from an intelligent and technological civilization. And evolution is full of "dead ends" even for sentient, intelligent species: even if dolphins were as smart as humans, their ability to manipulate objects is too limited to allow them to make space rockets. If you think about it, humans are creepily well suited to be an "advanced civilization", tool-users and makers that are naked without tools but with "clans" that allow them to have generations long memory and other humans to help with projects, etc.

"self-consciousness", whatever that means, is merely a product of a dense brain.Source?
There is no reason to believe life on an earth-like planet does not converge towards one or more species becoming civilized, bar specific environments.There's no reason to believe life on an earth-like planet converges toward one or more species becoming civilized, either...
Our current knowledge of the world also rules out a lot of the stuff that can be imagined in science-fiction. Regardless, the problem of the Fermi Paradox isn't even travel. It's communication. We've been sending sending very specific radio signals into the void for years now, and listening too. Yet we haven't found aliens doing the same thing.I wasn't, and I don't think Hans was either, discussing the Fermi Paradox when talking about space travel. Separate issues.

Evidence in earth species that we consider to be "self-conscious".That's not a source.
We are the evidence. Other chimps are even better evidence. Even those spoiled by nature have steadily developed their intelligence.One evolutionary path is not evidence that all evolutionary paths converge toward something...
Also what's the value in landing on a barge? Shorter return path or what?
I was surprised the thing bursted in fire so hard after crashing, too much spare fuel I guess?Saw some speculation that it was a controlled demolition, dunno why they'd do that though.

I wonder though, for how long has this experiment been running? If we've been listening for months and we only get something that matches now, does that frequency of detection actually match what we would expect, knowing the expected frequency of the events that could trigger the system?

Well, if we matched the detection to an actual, defined event then my point is moot.
Something like "this binary system right there".
Kinda hard to point at something you don't see. But apparently they need another facility in Europe to triangulate to the source location (distance between the two in US not far enough? dunno), then we can point and say 'right there'.
That I can easily understand. There's "tri" in triangulate. Finding the origin from two points is going to leave you with a whole surface. Some sort of funny two-sheeted hyperboloid where a section would look like when you put this into wolfram alpha: ((x - 5)^2 + y^2)^(1/2) - (x^2 + y^2)^(1/2) = 1. You need a third origin to further pinpoint the location of the source, and then on the top of my mind you will still have a whole curve of possibilities until you add a fourth point.
That at least is true if we start from the assumption that we only know the distance between the experiments and not the distance to the thing being detected. If we do it's merely a trilateration.
Actually the "tri" in triangulate comes from earth's position relative to the sun, at least when it comes to measuring distances to stars.
Dunno about black holes containing whole universe(s) but latest theory from Stephen Hawking says something along lines that matter black holes "regurgitate" could contain information about history of our universe.
http://www.independent.co.uk/news/science/stephen-hawking-black-hole-hairs-information-problem-a6819986.html
Apparently, some matter does leave the black hole and information it carries is "encrypted" (randomized, all over the place) or in other ways currently useless for us. My personal belief is that same thing happens with our conscience/mind&soul when we die. Energy transforms but is information it carries truly lost? Maybe there are ways to fix the glass after it shatters, to go back in time? It would render basic laws of physics useless but isn't that we all desire? Anyway, black holes are best thing in universe to research if you want to find out is our knowledge about universe set in stone or just subset of bigger knowledge bank that governs our and maybe many more universes. Problem is, we have no means to directly experiment on black holes. For the time being.
Stars are just definition of celestial object type. Saying black hole is a star means nothing. It all about properties of those celestial objects. Stars don't have same properties as black hole.
Also I just want to mention there are also no guns in space (yet).
The TP-82 pistol (Russian: ТП-82) was a triple-barreled Soviet firearm that was carried by cosmonauts on space missions.
It was intended as a survival aid to be used after landings and before recovery in the Siberian wilderness. The upper two smoothbore barrels used 12.5×70 mm ammunition (40 gauge), and the lower rifled barrel used 5.45×39mm ammunition. The pistol could be used for hunting, to defend against predators and for visible and audible distress signals. The detachable buttstock was also a machete that came with a canvas sheath.
The Salyut 3, although called a "civilian" station, was equipped with a "self-defence" gun which had been designed for use aboard the station, and whose design is attributed to Nudelman.[1] Some accounts claim the station was equipped with a Nudelman-Rikhter "Vulkan" gun, which was a variant of the 23 mm Nudelmann aircraft cannon, or possibly a Nudelmann NR-30 30 mm gun.[12] Later Russian sources indicate that the gun was the virtually unknown (in the West) Rikhter R-23.[13] These claims have reportedly been verified by Pavel Popovich, who had visited the station in orbit, as commander of Soyuz 14.[12] Due to potential shaking of the station, in-orbit tests of the weapon with cosmonauts in the station were ruled out.[1] The gun was fixed to the station in such a way that the only way to aim would have been to change the orientation of the entire station.[1][12] Following the last manned mission to the station, the gun was commanded by the ground to be fired; some sources say it was fired to depletion,[12] while other sources say three test firings took place during the Salyut 3 mission.[1]
...Due to reduced/no gravity, black powder weapons do not function properly....
My personal belief is that same thing happens with our conscience/mind&soul when we die. Energy transforms but is information it carries truly lost?Yes.
You misunderstood something. People believe guns do not work in space because of vacuum, has nothing to do with gravity. Zero gravity certainly helps, because bullet would go on forever, until it hits an object large enough which has its own gravity. That would bring the bullet down.
Modern guns do not need oxygen to properly work, gunpowder they use has everything it takes to fire a bullet (propellant and oxidizer). Biggest issue is how to keep pipes lubricated, because oil won't stay in the pipe like it does on planet Earth.
Yes.No.

Would that be a problem, since there is almost no friction in space?There is no air friction in space because there is no air in space. All other friction stays the same, so metal on metal is still undesirable. Temperature might be an issue though. One side of the gun gets heated up by direct sunlight, and the other radiates the heat away, so there could be a great difference in different parts' temperatures. Metals expand when hot and contract when cold, and that leads to problems like gas escaping between the bullet and barrel or too tight fitting between them, which can explode the gun. You get much faster overall wear, especially without lubrication. Try draining a car engine's oil, starting it at -50C and flooring the gas pedal. This is the same scenario, but much worse.

Even guns look better in space. Space without guns is like Russian without cyka.
