The water idea was Moronic... - Battle: Los Angeles (2011) Discussion

[–] mikedegot 13 years ago

It's like they said in the movie, our world has a large amount of LIQUID water. Yes there is ice out there on other worlds, but that ice isn't necessarily frozen water. Closer to the sun and H2O is scarce in any form, farther from the sun and you find frozen methane. Scientists aren't even sure how Earth ended up with this much H20 considering what we know about how solar systems form. It appears to be a total fluke.

If they saw such a blue gem sitting there for the taking in our solar system, they'd certainly go for it first before working with small amounts of gas or ice elsewhere. They'd eventually have to come here anyway.

If we found an uninhabited planet out there with small amounts of arable land and an inhabited planet with large amounts of arable land, you think we wouldn't make a move on the inhabited planet and exploit/exterminate the native inhabitants? Look at human history and you'll see how our noble lords operate when it comes to resources.

Having liquid water might not be such a super-fortune event.
It might have developed also here with the process called planetary differentiation where the heavier molecules fall inwards the planet and softer molecules rise up. Water is softer than the silicate and iron the Earth is mostly composed of so could have risen up naturally from beneath. But the Late Heavy Bombardment Event of asteroids could have really brought extra water components.

According to many planetary scientists Venus and Mars probably also had vast surface oceans later in the distant past but Mars is too light a planet to develop a magnetic field and so the water could have slowly split to hydrogen and oxygen components by strong solar wind. And Venus could have migrated inwards within the Solar System from her point of formation and on her current orbit the liquid water is no more possible on the surface (with the presence of heavy volcanic activity).

Our world is lucky that it's not too close to the Sun to be overly hot and also not too light so it has a magnetic field which defends the atmosphere and water from strong sunrays and also massive enough to sustain volcanism (without volcanism water would be frozen all over the planet even today). Up until about 1000 millions of years from now when experts estimate that the Sun will become too strong to be able to keep our surface waters.

But such circumstances can be pretty commonly met by other planets in the universe as well (at some time of their history).

I agree with you on that one. Even the idea of aliens invading for our water is not new. The concept had been employed in the 1985 television sci-fi series, "V". Technologically advanced bipedal reptilian humanoids covered themselves with synthetic artificial skin and faces to pass themselves off as oddly American-looking Caucasians and speaking perfect American English when first visiting Earth on the pretense of being friendly visitors. Yeah, they were shown visiting Los Angeles, of course. But they also liked swallowing live rodents for snacks and meals.

I've been watching the History Channel for years. I've learned that water is a very common element in the known universe. Now it looks like all of Earth's water came from bombarding ice meterorites during its formation. Supposedly out in the asteroid belt and the Oort Comet cloud there's zillions of these water asteroids floating around. There's even supposed to be a known water planet known as Glisa 20. The water planet is so big that the astronomical weight of the water actually compresses the lower depths into a substance akin to 'thick water', which we do not have on Earth. Now the planet Titan (or is it Europa?) is all water underneath its ice surface, vastly more water than Earth.

Water is a very heavy compound. It would be impractical for the aliens to steal and store enough for their own planet. More, the aliens could find water closer to their own home planet. What the aliens are looking for is a new home to colonize, presuming their own world is overpopulated or polluted or whatever.

reply

[–] antiglobe 13 years ago

"V" is epic.

Water is a very common molecule indeed, one of the most common.

Europa and Enceladus might have subsurface water oceans but only in a specific pressure/temperature layer within their interiors which meet the triple-point requirements of liquid water, not "all water underneath".

reply

[–] king_of_bob 13 years ago

I don't think you were paying attention. It was specifically suggested they were taking the water for fuel, not to drink it or return it to their planet. It seems to me they were going to take Earth and use it as a sort of interstellar\intergalactic gas station.

Now the planet Titan (or is it Europa?) is all water underneath its ice surface, vastly more water than Earth.

Moons. Not planets.

What the aliens are looking for is a new home to colonize, presuming their own world is overpopulated or polluted or whatever.

There is absolutely no evidence of that at all. As I said, I'm pretty sure they were going to end up using Earth as a giant gas station for further planetary conquest.

They were taking our water because to them it's a fuel source. They weren't taking drinking water. It's ship fuel for them. It seems likely to me that they were going to take Earth as a staging ground against some other enemy which would likely be a closer match to them technologically.

Taking our planet because they need a place to live is literally no better than coming here to take our water.

Why would they? It's a lot easier to just collect liquid water than make water out of it's base components. Just like sure, the average person COULD build their own computer, but it's infinitely easier for them to just buy a pre-built computer, so that's what most people do.

And if as I suggested elsewhere they're using it for cold fusion, they would need the water, not the base components. Which they would then likely convert into heavy water. Which is much easier than making water out of "nothing".

There is LOADS of water around in the univers, it is easy to make from its base elements = the movie plot is stupid.

1. It was a honest mistake, but thank you for your slanderous accusations. Maybe you should have said "Everyone can assemble a computer" if you ment = put the finished parts together. I wouldn't hold it against you, if it wasn't for your ridiculous claim that I misunderstood your statement on purpose. Learn to write in the first place or be prepared to specify your claimes.

2. You analogy is still a bad one. How does assebling an electronic device compare to a chemical reaction? Not everyone can assemble a computer (as you claim) but anyone can hold a match up to a balloon of hydrogen (and the time it takes is about a fraction of assembling a computer).

3. Sorry I don't bow down to your lightly written and not very specific random post about the subject we are discussing. The energy he mentions = a flame. Yup, that is it. A flame will ignite H2 and O2, as it is HIGHLY FLAMMABLE (http://youtu.be/fesgl5Cs5FY?t=3m28s). It ignites easily and the chemical reaction RELEASES ENERGY (http://en.wikipedia.org/wiki/Dihydrogen#Combustion) which is why it is used as a fuel source.

What!? The land of the free?! Whoever told you that is your ENEMY!

reply

[–] king_of_bob 13 years ago

1) There was nothing accusatory nor slanderous in my previous post. Which suggests you don't know what either word means. I meant "Build a computer" which most normal people would take to mean assemble a computer. But regardless of which words I used, you could have gone with the same idiotic interpretation of what I was saying.

2) It compares because you suggested literally anyone can "make" water. Literally anyone can ASSEMBLE a computer, most people don't have nearly the chemist knowledge to "make" water. As you've demonstrated here by suggesting you can "make" water by burning hydrogen in an oxygen rich environment. Which is absolutely NOT how you synthesize water.

Anyone with half a brain can put a computer together, most people just never try because they've been lead to believe by the likes of Futureshop that it's just so much easier to pay them to do it. If you can recognize shapes, you can build a computer.

3) While yes, a flame will ignite Hydrogen, Oxygen is simply the medium the burning takes place in. And burning hydrogen does not produce water. Note that using hydrogen as a fuel source is completely different from using WATER as a fuel source.

Keep in mind that your argument is "Anyone can 'make' water". Not that anyone can burn hydrogen.

While hydrogen and oxygen may exist in large quantities throughout the universe, nothing you've said suggests liquid water is in abundance, nor that you're aware of how to even "make" water.

And maybe you're unaware, but standard propulsion systems are wholly inadequate when it comes to traveling between stars. Simply burning a hydrogen oxygen combination would mean it would take them hundreds of years to get here. So when they take our water, they're clearly not just separating it into it's components and burning the hydrogen and using the oxygen to keep the fire burning.

Prof. Farnsworth: Oh. A lesson in not changing history from Mr. I'm-My-Own-Grandpa!

[–] Krisgebis 13 years ago

You claimed I misunderstood your argument on purpose (accusatory) because I didn't want to adress your real argument. That is an attack on my character (slanderous). And claiming I don't know what the words mean is in the same vain.

Ok, lets just drop your computer analogy as it doesn't help your argument. You may of course still try and point out its relevance, but please don't waste our time by just restating it.

When you burn hydrogen the byproduct = H20 = Water. What else would it turn into? If you can't come up with another reaction (I'm not holding my breath), then burning hydrogen = making water. Burning hydrogen doesn't just happen IN oxygen, the burning IS when hydrogen and oxygen react with each other. That means it's easy to make water, so why should it be difficult for spacefaring aliens?

I wasn't suggesting they were using hydrogen as fuel (you are welcome to point out where I did). Just that they can make water without spending energy (which was your exact argument). Infact they GAIN energy by doing so (which is a scientific fact).

So I have shown you have to make water and now to show that water is abundant in the univers (why does it have to be liquid? they could just transport it, or use the energy gained by making water to warm it).

[–] dbosityalpha 13 years ago

You are completely misreading what that link says. He was commenting why it would be difficult making water AFTER splitting it up into its elements and THEN making pure water from it. The energy to dissociate H20 into H2 and 02 would be very costly. However, recombining them to make water is an exothermic process that can be started with just a spark.

And H20 IS a product of a combustion reaction, just look it up in any basic chem book.

Aliens too stupid to understand and figure out how to melt ice into liquid water on a massive scale would never have the intelligence to make a space faring civilization. Water in any form is very common in the universe, after all, it is made up of the most common element H and probably a top ten element 0. Right off the top of my head, all they have to do is set up giant reflectors and aim focused sunlight to any frozen comet or planet. This is assuming they couldn't or didn't want to move comets close enough to the sun to melt them. Even if that wasn't possible, I'm sure people smart enough for space travel should be able to make liquid water efficiently.

And where the hell did they get the information that the aliens mainly wanted water anyway? You realize how fast they would have to be siphoning water to the point that they can see a dramatic change in the ocean levels? And this is with something like a dozen or so ships within a few days.

BTW water as a power source does not have to be for some sci fi cold fusion power. Regular hot fusion could use water as a source of fuel if they had an efficient way of separating heavy water from the oceans.

[–] proteus122 13 years ago

That didn't make sense to me. I could see them sifting through the sea water for deuterium or tritium for their fusion reactors (hot or cold) but why keep the ordinary water. There isn't enough deuterium in sea water to make the sea levels drop to any significant level if you extracted all of it, as far as I know.

reply

[–] The_Proprietor 12 years ago

Why is it so hard to understand that liquid water is the key here? It's not whether there is 'ice' (as discussed here - not all of it is water ice) elsewhere in our or other solar systems. Such as planetary bodies and comets. It's the fact that we have an instant and enormous source of fuel for them to use. That is a huge strategic boon for them. Because they do not need to 'treat' or modify the water in any way, other than perhaps remove the sodium chloride and find some other use for it.

In addition, Earth is a habitable and viable bio-dome. Perfect for creating a staging base should they seek a new home or a staging base. To do the same in space, you'd need a protective environment and that requires more energy and resources to run. Seems to me it would make more sense to save the energy and resources and use it for arms production for other ventures.

But the point is they're more than likely using our planet as a new colony and as a staging base for an attack against another enemy. Look at the nature of their attack: sudden, swift and rather frenzied. Their machines just like their bodies look worn, beaten and well used. Perhaps because they're tied up with a more advanced enemy elsewhere?

As for the water ice. You'd need to expend energy to turn that ice into liquid water. Considering what likely harmful substances that's bound to be in that water, in addition to the harsh environment of space which the Earth's atmosphere protects us from. Extracting that water would be hazardous I would imagine and require greater effort to make it usable. It's not unreasonable to suggest they would need to purify it more than they would here. Another important point. Their technology is a fusion of organic parts and machinery. Both need to be able to operate effectively, otherwise those separate components would be useless. For instance their water extractors as seen here:

http://unidentifiedenemy.co.uk/ (go to Transportation --> Water --> 3 (Extraction Device)

Are part organic, part machine. I don't see how such a mechanism's organic parts could operate within the harsh climbs of space or on Europa. Especially as they don't seem to be designed for deep space extraction. Is it really easier having to dig through all that ice for water? Or simply suck it up on Earth. Europa is estimated to have more water than oceans of Earth. But then they're not here to suck us dry, only to use what they need.

One thing, if they wanted water to drink or use in their bodies. As I assume they were at least cybernetic. Wouldn't it be safer to drink the water on Earth? Seeing as though it's not bombarbed by solar/gamma rays and other harmful substances. They'd only need to screen the water for harmful microbes, which would save the time, effort and energy.

If we agree the aliens are roughly 200 years ahead of us. We could argue that this attack was in part a pre-emptive one. Especially since the trailer and the viral material heavily suggests they've been observing us for a long time.

My second point was referring to their reason for coming for our water, excluding it being in a liquid state. As water elsewhere, such as in a frozen state on moons and comets would contain radiated and harmful material. Not ideal for consumption!

It's conceivable but possibly improbable that within a hundred years, we'll have made the first manned exploration of Mars and then in two hundred years time, we'll have reached the Alpha Centauri system. The latter I would think doubtful but who am I to second guess our future. I think 200 years as a rough estimate is a good point from which to start. Seeing as their weapons technology isn't that far ahead of ours. But then if they are a scavenger species as the film suggests, it's possible that interstellar travel may have an ability which they acquired by conquering another species.

As for your second point. Both the film and viral material suggests otherwise. Firstly go here:

www.unidentifiedenemy.co.uk (go to Transportation --> Water --> 3 (Extraction Device)

It's clear the enemy is part organic and therefore those organic components need nutrients and fluids and water would be an important factor there. The professor on that news segment whilst only offering an educated guess said the water more than likely powered their own bodies as well. If you remember that scene where Nantz is dissecting a live alien, a lot of water came out of it. Which to me would suggest they want the water for their own bodies in addition to powering their technology.

As for the staging ground theory. I've found this article segment which is interesting:

Homeworld

While little is known about the origin of this mysterious alien race, it has been implied in interviews that the homeworld of the aliens is a chaotic, possibly war-torn place and that the extraterrestrials involved in the invasion of Earth may not be part of the dominant force there.

Also, if an advanced civilisation wishes to invade, colonise or wipe us out, there be very little we could do about, or probably even know about it. They certainly would not be running around in full view proving vulnerable to our weapons.

The assertion that the aliens may be able use liquid water as a energy source makes infinitely more sense than the failed plot device that water would be toxic (http://www.imdb.com/title/tt0286106/). Perhaps this was an attempt to balance the illogical nonsense purported by Signs?

Reference further down this thread, water most certainly is a byproduct of combustion: http://en.wikipedia.org/wiki/Combustion

A simple example can be seen in the combustion of hydrogen and oxygen, which is a commonly used reaction in rocket engines:

2 H2 + O2 -> 2 H2O(g) + heat

The result is water vapor.

Since the movie claimed water as the power source it would have been nice to see either droplets of water or water vapor coming from the alien's aircraft. The analogy would be the water commonly seen dripping from a car's exhaust pipe.
