SO I"M DOWN! ( i say close, cuz whenever i watch the discovery channel they always talk millions or even billions of LIGHT years away) | ||

We've known for quite a while it resides in the habitable zone, but we don't know the atmospheric composition for one thing. It's far too early to get optimistic. It raises the chances but people are acting like we discovered life elsewhere or something. | ||

That's not the least bit true in any way. If a planet is too far from a sunlike star it will be too cold to support life, and likewise anything too close to a sunlike star will be too hot to support life. If you think about the conditions on Earth that support life, the concept isn't that difficult to understand. Now, the real question is will we be responsible for an alien invasion should we make contact with the inhabitants of said planet? | ||

Just imagin what we will be able to do in the next 50 years (except if you are 50y/o or more) This is very true. The first flight to landing on the moon was a considerably short amount of time, compared to how our lifetimes are at the moment. | ||

Yeah, spacetravel can easily be more technologically doable The key problem will be energy supply, as spacetravel just takes up an insane amount of energy, and we're already quickly bottoming out on natural resources. So if we manage to fix that with some smart physics solution, then perhaps.. On a side note, lifetimes haven't really increased all that much, this is a misunderstanding. Less people die young, so the average life expectancy increased over the past few centuries, but old people got to be about 70 a millenium or so ago, at best we've 'prolonged' that age by something like 10 years? Anyway, that minor lifetime increase is irrelevant compared to the technological advances that we are making | ||

It raises the chances but people are acting like we discovered life elsewhere or something. completely agreed. all this sensationalistic NEW EARTH FOUND OMG lately is getting on my nerves. finding planets within habitable zones is completely expected and nothing to freak out over, especially since these discoveries have basically zero relevance concerning the possibility of life on other planets as long as we have no valid theory of how life evolved on earth and how high the chance for life to evolve somewhere else is, even given the abundance of elements that are thought of being necessary for it (carbon, liquid water, amino acids, etc...) i still tend to believe it was a one-time event. one shouldnt assume earth to be less significant just because the cosmos is so big. a very interesting argument for the cosmos actually not being big at all but just big enough for us to exist was given by tipler in the anthropic cosmological principle: assuming what we know about the physical laws of the universe is correct, the universe has to be the size it is since its size is linked to its age due to the process of expansion. and it has to be as old as it is since it has to have enough time for a couple of generations of suns to die in supernovaes to spread enough heaver elements into the cosmos to enable a mineral-rich planet like earth to exist anywhere in the universe thereis really no philosophical or scientific reason not to be a little anthropocentric until we actually find life somewhere else... we might be the first... we may be the only ones... who knows?

Anyway, that minor lifetime increase is irrelevant compared to the technological advances that we are making you couldnt be more wrong really. energy supply isnt the issue, space travel doesnt take a lot of energy since you just keep going after you accelerated and can use gravity around planets or stars to accelerate more. the real issue is the human body and psyche, neither are built for the stress of long-term space travel, even spending half a year on the ISS wrecks your body. so the real issue is to find something to preserve humans like cryogenic freezing, or abandon manned spaceflight altogether and focus on robots (the more likely option imho) realistically, manned interstellar travel might as well be impossible for us to ever achieve, but of course thats very hard to predict... | ||
