No they wouldn't because they rely on the expansion of gas from the propellant. Any weapon that relies on gases/combustion would not work. The only way they would work is if they are fired from within something that has an atmosphere and then exits into space with initial velocity. Like if they fire something inside a space station and it travels outside, that would work.

Either that or do the other thing you mentioned. Send space capable ICBMs into another planet thing would work, but it would take a loooooooooong time to get there (if it isn't hit by space debris and detonates before it gets there).
...? Am I missing something here? Why wouldn't simple gas expansion work? Gases can still expand in space?
And yes ICBMs could get hit en route and would take a long time, but since no ones on the ship it could take as much time as it needs.
Because conventional gas expansion systems rely on ignition of a propellant within the chamber. Ignition can't happen in space because there is no oxygen or any other fuel.

Man if only Hawking wasn't wheelchair-bound. Then we could just let the 'Gordon Freeman' effect take its course.

- theoretical physicist --- dues # 1 --- check

- never speaks --- at least not with his voicebox --- check

- can wield a crowbar --- damn....

We're just 1/3 away from meeting the criteria to save our species...

Well, I still feel that, considering that we have laser, anti-matter and plasma technologies, i'd still think they'd better come in peace, nontheless
...
just in case :)

Man that would be awesome! Thanks to you I can only ever picture Hawking as Freeman IRL!
Damn you hans! damn you! but thank you all the same

"Stephen Hawking, the famous theoretical physicist that spends his time trying to figure out the things that nobody will ever figure out about the universe, has warned humanity to avoid alien contact at all costs."

Avoiding? How? Did someone invent a way to move the planet and didn't tell me?

And there are million's of signal's being send each second, and some of these will reach into space, so unless we stop modern civilisation or put a aluminium bubble around earth it won't matter in the long run.

I wonder why when the subject of alien contact comes up, that everyone silently assumes that aliens will be more advanced that us, and that they will be the one's finding us.
What if we are ahead of the game? Would an alien life form even wish to be found by us?
Well, our planet has had several extinction events that set us back hundreds of millions of years. Look how far we've gotten in just 100 years. It wouldn't take long for aliens to be way ahead of us.

Who's to say that we're even on the same frequency as other species (for lack of a better word than "frequency", I feel as though it's the incorrect term in this situation), we've got many different methods of sending signals, digital, analog, the chances of them using the same method as us is so low that it's laughable, we're undoubtedly sending incompatible messages.

Even if man ever does find a way to contact another intelligent species it's almost certain that we'd never be able to speak or understand each others dialects, not because of translation complications, but because of the shape of our "mouths" (for lack of a better term), a Dog for example can be trained to understand commands and may even understand words and their meanings, but no matter how intelligent the dog may be it will never be able to speak a human dialect because it's mouth shape, tongue, etc won't allow it, the same applies to other animals and obviously alien species. HOWEVER there's a chance that if our species became truly integrated and peace was made, through extreme effort our species might eventually be able to understand each others languages, but still speak our own (For example, the way humans and the "prawns" communicate in "District 9", each being able to understand each others language, though not being able to speak it themselves), though such a process would be unbelievably difficult.

These issues will undoubtedly lead to great conflict between our species, whether one side isn't completely fucked up is up for grabs, whether this can be overcome in regards to relations is also up for grabs (like the relationships between nations, but even greater and infinitely more difficult to deal with; for example Germany and England were some of the greatest enemies known to the world, especially in WW2, however now they're close allies, Japan invaded China long, long ago, things are still pretty shitty between the nations). Meaning that trying to communicate with aliens is pointless, we can continue pissing away time and money attempting to call other species, but there'll be no result. The only way to actually come into contact with an alien species is if we physically find them and work from the ground up. GET READY FOR SMOKE SIGNALS *****!

Let's not forget our environment, odds are they couldn't breathe Earth's mix of air and we'd die from theirs, the effects may be detrimental to one species and of a great benefit to the other (unless they've a larger amount of Oxygen than Earth, then their home would be sensational and maybe even prolong our life spans, unless they have different requirements, perhaps they're like Earthen Flora and actually Breathe in Nitrogen instead, the possibilities are unfortunately endless. Though in such a we'd probably attempt to invade their home or vice versa, something I'd support because the idea of a longer life is awesome).


EDIT: In regards to other comments about District 9; one of the greatest, most amazing films to have ever been released, I honestly think it'll stand the test of time and become a classic. Not to mention that of all the "alien encounter" movies out there it's the most realistic, which in a way is kinda of sad, but the universe isn't all sunshine and lollipops.

But we've already contacted aliens... Who do you think gave us velcro?
Even if they ate babies, and had the technology to destroy galaxies we'd still win.
Because their women are ugly. And we have the greatest weapon of all... Earth germs.

i'm not robbing the idea or anything, but once while discussing with my dad and some friends, we arrived to that conclusion also. that it is probable that an alien civilization might do as Columbus with or without knowing what their doing.

As much as I'd like to know if there really are aliens out there, I kinda see his point.

...well yes if you forget to add gunpowder to your shells. Gunpowder has its own oxidizer in it and can fire in space for that reason.

This all reminds me of Titan A.E. except I doubt we'll have some super special awesome ship to create a new earth. :p

The Russians have made a spy space station with a MG on it once. It fired successfully.

Umm... there's no point in worrying about sending out signals for them. We're doing that constantly anyway. What with all that TV and radio and communication signals and letting probes drift off into the interstellar void, there's really not much we can do to make ourselves more obvious. Sending a signal letting them know who we are and how to talk to us along with all that trash seems harmless enough to me, since if there are any aliens receiving the signal, they already know where we are.
But all those things could get lost in the background radiation and such, the probes don't get to leave our solar system and the signals get scrambled to meaninglessness with added radiation from stars. What we are broadcasting as a message is clearly a message if anything gets it because we are using math witch we believe is a universal language, something all of sentience that is intelligent will have to use and know. Radiation from a system? Not unusual. Radiation mysteriously forming prime numbers and equations? Slightly suspicious.

If they are as advanced as Hawking hints then why would they give a shit about us? There is a reason Italy doesn't invade San Marino. At a certain point we are just so small that we aren't worth the time.

Any planet that has the ability of intergalactic travel can smush us in the blink of an eye. just like there is no honor among thieves i suppose that there would be no honor among aliens. to them we would look just like all the creatures we use in the wild and would most likely be used for recourses. But wouldn't it be awesome if they were uber cool and gave us all jet packs and the ability to blow things us with our minds.

Are we thinking about the same shadowy puppet masters?

There's a lot of background radiation already floating around in space. Some of that radiation is residual signals from the Big Bang. Any of our signals would be buried within the rest of the CBR (Cosmic Background Radiation). If anyone were to find our signals they would have to be actively looking for it and filtering it out from the CBR. In fact that is exactly what the SETI (Search for Extraterrestrial Intelligence) research facility is doing right now.

My point is essentially this: If aliens were to discover our signals, they would have to be actively looking for them. And in order for them to do that, they have to be fortunate enough to receive our signals before they dissipate or are lost in the CBR
While quite audacious, your argument makes one fateful assumption: that a race advanced enough to visit Earth would not be able to see past CBR. I think that considering the massive achievement space travel at high enough speeds to reach Earth, detecting such signals could very well be child's play for such extraterrestrials.

Dissipation is perhaps more likely to stop them from hearing than CBR. However, we would not know how far their senses would reach from wherever their location happens to be, and there is some chance that an advanced enough civilisation will reach within the needed area during any great voyages, assuming they have conquered safe light speed travel (which would more or less be needed to get here without birthing astronauts during the trip, catering for muscular atrophy, etc).
