I am by nature a skeptic, but I am also very gifted with math and science. I know many people do not believe there could or is life out in the universe, and so on, but for me I can't imagine how life could not exist. So if you are someone who thinks alien life is impossible just skip this. I am very familiar with Frank Drake's equation, and when one considers 75% of our water came from comets, and we know from the recovered camera on the moon that microbial life can survive space. It seem very logical, given a Universe ~14B years old, and our planet only 4B of that, that life surely could have had many life-spans elsewhere. I think the problem is intelligent life. My internal guess is that we would find only 1 in 1 Billion plus planets with life to have intelligent life. My guess comes from the number of life forms that existed here that reach the point to plant a flag on the moon. So even with that, 10B^10B+ suns out there, that is enough 0's to make a book.
Anyway, I do agree with Mr. Hawking that sending a pulsar-star map saying "here we are" is kind of like throwing your window out the window in a random neighborhood. Eventually WE will be these evil invading aliens, so why no another race who got their start 6 Billion years ago? Can you even begin to imagine the technology advancements of 2 billion years? We won't even look like we do now. In fact, we would probably look closer to the "grays" given our life-style trends. Look outside? ewww!
First, would an alien race want our planet? The answer is you bet! Would you pick up a $20 bill on the floor? Our planet has an incredible supply of Hydrogen. The building block amazing element locked in our oceans. Not only Hydrogen, but the temperate climate is very ideal. So my personal assumption is that if an alien race existed, knew about us, and could get here....well.....
I laugh when I see movies which show us out-smarting an alien race, especially writing a computer virus to a "mother-ship" talk about Bill Gates pulling overtime.. I thought of how silly it would be for a caveman to throw a spear at a tank. He doesn't know it isn't an animal, he doesn't know what a diesel engine is, he doesn't know what a shell is, the list goes on. Being an electronic engineer, we can't even keep up with our own code and processors, let alone one 100 to 2 billion years advanced. Anyway, I digress. There are a lot of theories about what would happen if an alien race came upon us and wanted to rid the ants (us). The odds that their natural home atmosphere being even remotely like ours is way too small. Unless they want to preserve any life, which is pretty useless really, they would most likely simply terraform our atmosphere, killing everyone, no matter where you hide, or what altitude you try to escape to. Suppose theirs is 7% Oxygen, 20% CO2, 3% ammonium gas, 60% Nitrogen, and 10% Helium. How long would you last in that atmosphere? So all the Hollywood sci-fi about infantry like devices with shields are so unnecessary. Even worse, perhaps they just remove our atmosphere, or ionosphere. Simple. This is how we would know we are done for. The US gov. is not going to tell us there is a massive mother-ship full of aliens who are looking for a new home, or to fuel up at our big blue 7/11. So perhaps we notice odd shapes in the sky and within hours everyone is coughing up blood, and passes out. Then maybe they scorch the earth to rid all the bodies, which wouldn't rot since the planet would be sterile. Fresh start. Isn't this what we do to new places we want to build? If you where an ant in an anthill where a new hotel is planned who is going to win? The movie Skyline I think was great for special effects, but mainly for one thing. We didn't win. Let's face it, an advanced civilization is not going to consider us equals, or worth negotiating with, no more than we would with the ants.
This is just my opinion. I welcome arguments....|||My speculation is not the same as yours. I do believe aliens exist and I believe we already made contact with more than one species of aliens. Our signals can travel faster and longer than any space ship, I would think the aliens have similar, but more advanced methods. But we can also speculate that they're already here, walking among us with some esoteric agenda. Haven't we been getting a lot more public sightings recently? We had that one in China that shut down the airport; China disclosed it. We just had the mystery missile in the US, the government won't discuss the details except to say "it's not a threat to national security". There are a lot more I cannot remember the names and places of, but you'd find them by looking it up on youtube or something. We HAVE been seeing strange things in the sky.
I don't believe all species of aliens are bad, after all there is some good in human beings and I'd like to assume the gift of a brain inquires choice; a sense of right and wrong and an understanding between what should be done and what has to be done. I favor the "Day the Earth Stood Still" method over "Independence Day" resort. There might be a good species of aliens first that notice us. After all, wouldn't a morally bound race be more advanced than a greedy one?
Human beings would be much further along in our advancements if those in power were less selfish. There are two paths to advance technology, one could either follow Thomas Edison or Nikola Tesla. Though Tesla's way consisted of free (unlimited) energy and Edison required the use of fossil fuels. Because money was involved we lost out on the possibility of free energy, powerful bankers like J.P. Morgan funded Edison because it brought about more profit. I wouldn't doubt that the alien beings rely more so on Tesla's techniques than combustible fuels to power their space ships.
Clearly any alien race would know what we know plus some, so there wouldn't be much of a point, they'd be on the losing end of the deal if we traded information. They might already know how to bend space and time and find ways to teleport or warp through space, splitting the distance. A long time ago, humans sent out signals containing out DNA and genomes, so by chance an alien race caught the signal, they already know our weaknesses.
If it was an evil race of aliens determined to take over our planet, I'm not sure mass extermination would be the way to do that. I'm sure diminishing the human race would be one way, but I think they'd find use for our species such as a slave race. Maybe they're working on a way to lower the population, like is suggested on the Georgia Guide Stone... for all we know, they paid to put those tablets there. Destroying the ionosphere would kill most people off, but it would also kill all plant life and animal like, I don't think hydrogen would be the only resource they were after and taking out the ionosphere would just drastically change the climate on the planet to the point they may not even want it anymore. With unlimited technologies, they might even know how to control a planet, thus they'd realize how fragile a life sustaining world could be. I think the most efficient way would be to genetically alter viruses, kill humans, but leave the rest of the planet up for grabs.
I have no answers, but just the belief that they're already here. You said it yourself, the government wouldn't tell us, so how do we know they're not here now? Human technology, I was told, has advanced too quickly within the past 60 years, I wouldn't be a bit surprised if we reverse engineered some higher technology or was given it by higher beings in exchange for something else... but what do we have that they could possibly want? Loyalty? Our government's not stupid enough to go to war with a space faring race thousands (If not millions) of years more advanced; upon facing the threat of extermination I think they would much rather agree to be loyal to them. But to avoid panic from the masses, they don't tell us and slowly try to gain control of the planet into global hegemony. So is it possible those in the government are really just working for a higher power? I know it's a scary thought, one that you probably don't even want to consider. This isn't necessarily my opinion, but I wouldn't overlook it.
We can even look into the Ancient Alien theory and wonder if there's some truth to that. I hate the idea of forfeiting the theology of God to aliens; but just for speculatory purposes, suppose aliens did land here a long time ago. Either because of their unspeakable technologies viewed by primitive man they were thought of as gods, or aliens knew the destructive behavior of man and implimented religion as a barrier for moral aspects. This would bring about the suggestion that religious deities were a form of Star Child.|||Sticking the original topic, re: more advanced aliens having an interest in earth, I feel the movie %26amp; scifi stories are rather naive and severely limited by our own severely limited %26amp; naive human point of view when it would come to... Them up there.
If I was an alien commander, sent here to eradicate humanity to claim earth for my "empire" or whatever, the most STUPID way to do that would be to land there and basically say "lets you n me fight!" If you look at it properly, that amounts to 1st grade playground war rules.
So how would I attack earths' humanity? I would do it in a way that had no danger for me at all, and in a way that humanity could do absolutely nothing to prevent or stop, or recover from.
What comes to mind? Well, if I have already mastered interstellar/interplanetary travel, I would simply take a trip to our asteroid belt, push several 50 mile wide asteroids on a collision course with Earth, then sit back %26amp; enjoy the fireworks show. Absolutely nothing humanity could do about that (Independance Day movie aside-LOL), and no danger to me.
To actually GO THERE and demean myself with personal contact would be like us trying to get rid of a wasp nest..by building little technologically superior ufos to zap them one at a time, that are small enough to actually be swarmed %26amp; defeated by the wasps in some way! See? Thats really a dumb way to do it- actual wasp exterminators get rid of them in a way that is no risk at all for the exterminator, and in a way that the wasps can do nothing about.
So yes, my version of alien attack on Earth would be "astronomers detected 210 'earth killing' sized asteroids on a collision course with Earth-oddly they are all arranged to strike at the same moment! WOW! Hey! so there IS intelligent life out there! We have yet to detect any UFO's at all at this point, though..so, I guys we're doomed"
;) makes for a boring movie, but probably more realistic!
Here is one "comforting" point to make, though: MAYBE that is the thing that makes humanity so special/monstrous in the"galactic" neighborhood...and is the SAME reason that the others dont want to talk/show themselves to us: only humanity is capable of even IMAGINING SUCH A VIOLENT AND BRUTAL ATTACK PLAN IN THE FIRST PLACE! And I'm no strategic genius-I'm just your average typical humanbeing, sitting here in my living room, thinking for a whole 5 minutes how I would wipe out an entire worlds' population safely %26amp; absolutely- and that came to me easily.
So, in the end, we could actually be seeing everything backwards: we aren't the helpless inferior technological species...we are the terrifying monstrous species that could kill their neighbors with the right (rather weak) justifications, the ones who would actually conceive, design and make thousands of nuclear bombs, and yet who haven't killed themselves off yet! Yikes, right? If I was an alien commander, tasked with getting rid of those such as us, I wouldn't even give them the opportunity to launch their nuclear arsenal at me.
There are better ways to crush a planet, to eradicate a violent species. Hehe..lets just hope I'm not REALLY that alien commander up there, showing my hand, using earths internet, smiling wickedly as the rocks are already on their way! ;%26gt;|||1) stop with the coffee, it's making you paranoid.
2) Independence day was only a movie, I loved it but I never believed it. The "Virus" was an in Joke, an homage, to anybody who read HG Wells' "War of the Worlds" where the martians were killed by common cold virus.
3) the chances of anybody finding the Voyager data is Zero
4) If Aliens are common, the chances of one being within 500 ly is remote, about the same as me being killed by a tiger in the UK.
.|||Aliens won't be coming for our hydrogen. There's a lot of places in the universe to pick up that stuff.
Aliens won't be coming here for our temperate clime. They prefer far more ammonia in their atmosphere.|||So much to read. Yikes.
Hey, its a free country, you are welcome to believe whatever you like. Believing Flying Saucers filled with aliens carrying little blasters aimed at us Earthlings is okay, I guess. However unlikely.
Seriously, besides the part about Drake's Equation, which is crap, its hard to argue that somewhere in the vast Universe there might be life, but don't you think there is really no way to find out? The words "vast Universe" might be your first clue. If you believe Einstein was right, then interstellar travel is pretty damned unlikely.
Still, you are welcome to believe that the whole Universe is full of Little Green Men and that they like to perform experiments on hillbillies with orientation issues. Maybe the crystal implants are really alien "Bark Off" units, designed to shut people up like we collar a noisy dog? Heh, I guess you really don't need any more ideas for conspiracy theories, right?
Post some pictures of your tin foil hat collection, okay?|||no alien species, unless it exists in our own solar system, will ever be able to travel here... and vice versa.
when cross communication with a species 20 light years away takes... well, 40 years for a response, it pretty much means it it completely irrelevant if they exist or not. heck, perhaps the universe is SWARMING with life around every single star.
it's still going to take 75,000 years for the closest aliens to get here.
i'd also argue, you can't assume the universe was ripe for life to form int he first 10 billino or so years. a universe composed of only hydrogen and helium, and minor amounts of deuterium is not going to instantaneously create life. you need heavier elements. at least two generations of supernaove (6-10 billion years) to generate enough "heavy elemtns" to establish life.
now, life could be vastly different than what we think it is, in which case, maybe the aliens are inside of baryons.|||"Our planet has an incredible supply of Hydrogen".
Hydrogen happens to be the most common element in the universe, making up about 75% of it. There are gas giants made out of almost pure hydrogen. Comparatively, the earth has a scarcity of it. There are also whole moons made out of water ice. Titan is covered with hydrocarbons. The asteroids contain far more heavy metals. There's really nothing that the earth has that you can't find abundantly anywhere else in the universe, except life and the proper set of conditions for it. If they want to resettle on our planet, I doubt they'd be able to transport their entire population hundreds of trillions of miles through hard vacuum to do it. And if they could, they would certainly have the ability to terraform a planet instead of stealing it. Still, although I am unable to foresee any danger from extraterrestrials, it doesn't mean there aren't any.|||I do like the point of Interstellar travel, warp speeds %26amp; billion year old civilisations,
If they could travel to us would they, why is it we can't detect any sort of trace of high energy outputs from these wormholes, warp engines in our own galaxy's. How much is the governement holding back when it says scans the skies. As they say in Star Trek "Scan For Warp Signatures"
As for being prepared to battle aliens, i suppose any that travel here would be able to annilate us, i guess they would need some type of force field to travel at great speeds through spce, debris %26amp; micro comets %26amp; stuff, let alone space bugs on the windshield.
You do know the most powerful bomb ever detonated created a mushroom cloud 40 miles high, probablr devestated the surronding area, that was 50 Megatons, they were planning for 100 Megatons, but the russians ain't as crazy as they seem. so anyway that was what
So That was almost 40 years ago, 15 years of delevoping nucleare wepons creates a bomb with fireball 5 miles in diameter a shockwave was felt over 600 miles away, would of given 3rd degree burns over 65 miles away %26amp; the base of the cloud was 25 miles wide, that was when th ebomb was exploded at a height of 2.5 miles, on the floor that could of been made the destruction spred even further. So with todays technology a 200Megaton Or even 500 %26amp; 1 Gigaton Bomb would almost cripple a small country, england, scotland, wales, devastate most 3rd world coutries
But then you have to get these things to the aliens space ships, which would be armed with lasers %26amp; such what which would make our rockets more deadly to us from emp blast to radiation fallout.
Aliens, warp speed %26amp; billion year old civilizations, well one thing at a time eh,
