strange story.

[Silverthorn]

I myself didn't see the UFOs but there was a big news report on CNN last year (or was it in 2007? I don't remember anymore) talking about UFO sightings in Texas, about 15 minutes away where I lived. The funny thing was that we actually got a bunch of tourist from all over the US coming to our town to watch any possible remnants the aliens could've left. One guy actually worked as a guide to lead the tourists to the alien sightings. $100 for the tour, $1000 if they actually see aliens

It was more marketing than actual alien-watching. And isn't the USA the center of capitalism, the center of marketing ideas? :P

Like already stated, the chance of seeing an extraterrestrial species is lower than getting struck by lightning while winning the jackpot in a lottery. Just to give some facts according to modern scientific knowledge. Over 1 billion years, the only species on earth were little, stupid protozoa. You wouldn't expect them to build a space ship, fly to a planet which is probably over 20 light years away, say hello, and fly back. The only species on Earth who has been able to build a space ship is human mankind, and the homo sapiens sapiens has been on this planet around 20000 years. 20000 years. Sounds much. Well, no. Earth has been dated to 4.6 billion years, the entire universe to 14 billion years. So, 20000 years would be around.... 0.0001% of all existing time. Now, in this relatively short time span, we've only been able to travel to space for around 50 years.
Now, imagine the evolutionary part. Protozoa evolved to multicellular species by coincidence. Multicellular species adapted to their conditions, they use oxygen to live (disregarding the species that use sulfur and the like). Well, great, most of the live is based on oxygen, water, and sunlight. Without either one of them, we wouldn't be here. Now, imagine a species which breathes (if they breath) hydrogen, drinks (if they drink) mercury and needs total darkness to survive. Would we expect any live under these conditions? No. Would others expect live under the conditions that we have? Maybe. We don't know.
According to Einstein's special theory of relativity, the mass of an object increases the faster we get. At the speed of light, our mass would be infinite, and Newton says that you need a certain force to accelerate something. Therefore you need an infinite amount of energy to be faster than light. Conclusion: if it was possible to "jump" over a certain speed, it would be possible to travel long distances in a convenient time. As this isn't possible, space travel to distant stars is actually just a cool-sounding idea but not realizable whatsoever.

So yea, any questions about aliens saying hello to you?
