Persia Posted November 22, 2011 #1 Share Posted November 22, 2011 When searching for alien planets that could host extraterrestrial life, scientists should broaden their minds beyond "Earth-like planets," researchers say. http://www.space.com/13701-search-alien-life-earth-planets.html Link to comment Share on other sites More sharing options...
HMS Dreadnought Posted November 22, 2011 #2 Share Posted November 22, 2011 It makes perfect sense to me, who knows what varied forms of life have occurred under far different conditions to our own planet. Link to comment Share on other sites More sharing options...
Bildr Posted November 22, 2011 #3 Share Posted November 22, 2011 (edited) Makes perfect sense indeed, if you think about the possibility of Silicon base life form, instead of carbon like us(per example). http://www.youtube.com/watch?v=-yGoab3duYY All known life on Earth is built upon carbon and carbon-based compounds. Yet the possibility has been discussed that life elsewhere may have a different chemical foundation – one based on the element silicon. http://www.daviddarling.info/encyclopedia/S/siliconlife.html but for silicon based life form to breath oxygen is a little problem, maybe they would breath something like sulfur instead.

Bildr Posted November 22, 2011 #4 Share Posted November 22, 2011 Like some on said on the link comments; "I just hope we can find Humans on earth first... have you seen any, lately?" We should think about finding our own humanity and caring of our life here on earth before looking for somewhere else... Link to comment Share on other sites More sharing options...
scowl Posted November 22, 2011 #5 Share Posted November 22, 2011 This makes sense since we have no idea what causes life in the first place. Link to comment Share on other sites More sharing options...

psyche101 Posted November 22, 2011 #8 Share Posted November 22, 2011 Is this not exactly what we have been contemplating for years? I thought we were trying to get something together to burrow into Europa. Link to comment Share on other sites More sharing options...
badeskov Posted November 22, 2011 #9 Share Posted November 22, 2011 Is this not exactly what we have been contemplating for years? I thought we were trying to get something together to burrow into Europa. Indeed so. Testing a Europa Probe Prototype Just one example and I am sure there are even olde articles around.

Frank Fontaine Posted November 22, 2011 #10 Share Posted November 22, 2011 Not to trample on anyone's parade, but if silicon based life is as slow as it is suggested in that video above, would we really call that "life"? Link to comment Share on other sites More sharing options...

Cheers, Badeskov As long as they remember to put a Aluminum Tin Foil hat on it this time ! THe Mars Rovers scared all the Martians underground !

docyabut2 Posted November 23, 2011 #14 Share Posted November 23, 2011 Like scientists said if there life out there, you don`nt want to know in what forms:) all I remember is that movie Starship Troopers ,a bug with a brain!!! Link to comment Share on other sites More sharing options...

That was just a movie. Considering out pool of one, it seems highly likely that our model of a bipedal creature with opposable thumbs is a design that will assit the climb to intelligence. Therefore I suspect most Intelligent Aliens will look somewhat similar to us. As with convergent evolution on our own planet, whereby we saw Marsupials that look just like canines, I feel our model is likely to lead to success in other environments as well. Of course for life, that parameter is fairly open. Link to comment Share on other sites More sharing options...
Timothy Posted November 23, 2011 #16 Share Posted November 23, 2011 Sure there will be life on planets unlike Earth. However with what we know and with the limited resources don't you think it's more practical to work with what we know? Link to comment Share on other sites More sharing options...
Widdekind Posted November 23, 2011 #17 Share Posted November 23, 2011 Intelligent Aliens might not live on planets, anymore, at all (but, have become completely "space adapted", living in artificial superior-to-planets space habitats) Link to comment Share on other sites More sharing options...
scowl Posted November 23, 2011 #18 Share Posted November 23, 2011 There's no reason to speculate about other strange life forms. We'll know life when (and if) we ever see it. We're not excluding planets. Link to comment Share on other sites More sharing options...
PersonFromPorlock Posted November 24, 2011 #19 Share Posted November 24, 2011 One problem is that if the alien life is different enough, we might not recognise it as being intelligent: we've been debating the intelligence of dolphins for 65 years without coming to a conclusion, for instance, and them we can lay hands on! That's why I've said for years that SETI should be looking for alien radar signals. Radar's too useful not to be exploited by anyone who's discovered it, a water-oxygen atmosphere dictates its frequency parameters, and the very high-powered and directional beams should carry well. We may miss the more alien technologies this way, but if we discover a 3Ghz pulse-modulated signal with a 400 pulse-per-second pulse recurrence frequency and a ten-second recurrence rate coming out of a distant planetary system, we'll have a pretty good idea of what we're looking at.

Robbo Posted November 24, 2011 #20 Share Posted November 24, 2011 (edited) RADAR won't travel that far. The standard airport Watchman will give you about 60 miles. Ultra low frequencies will travel a lot further. However any signal producing equipment would have to be based in orbit if you wanted some form of space RADAR since high frequency waves will be massively attenuated by the atmosphere and low frequency waves tend to bounce off the ionosphere and back down to Earth. In order for us to detect a radio wave from another planet, that planet must have deliberately sent it our way, since anything else will just appear as random spikes in the spectrum. No way is anyone on a distant world sitting down to watch Hitler's broadcasts. Anyway - aren't we already starting to look for life in all kinds of places? 20 years ago no one would have given Europa a second thought but now the subsurface ocean theory seems to be the strongest.

Just Dave Posted November 24, 2011 #21 Share Posted November 24, 2011 Even if we find life i doubt it would walk on 2 or 4 legs i doubt it would even walk. If there was any intelligent life in our solar system they would already came here to say hello, because we are about to discover them and we just started with some brave space travel plans and concepts.. So 2 options, first they are hiding from some unknown reason second they arent intelligent at all, bacterias or some other sort of micro organisms.

If there was any intelligent life in our solar system they would already came here to say hello, because we are about to discover them and we just started with some brave space travel plans and concepts.. We've already proved beyond any doubt that there is intelligent life on a planet in our solar system. Link to comment Share on other sites More sharing options...
