On a single other planet? Very close to 0. But multiply this number by say 400 billion for our galaxy, and maybe additional 150-2000 billion for all the galaxie

On a single other planet? Very close to 0. But multiply this number by say 400 billion for our galaxy, and maybe additional 150-2000 billion for all the galaxies, and the chances are not that bad. Probably.
Plus the idea that life needs to look the same as here on Earth has no logical base - it could be from number of other elements, forms etc. Basic premise is just multiplication, where it goes from there is anybody's guess. Carbon with water is convenient but its not the only option.
- matthewfelgate 6y agoWhat other elements do you think could form life? Or are you speculating there could just be such different physics out there we struggle to image what different worlds could be out there.
- fogihujy 6y agoSilicon has been suggested as an alternative to carbon as basis for biochemistry. Ammonia-based life has also been suggested (and is also a rather common sci-fi trope).
- bregma 6y agoIt's both water and carbon that are necessary for our kind of life. Interestingly, I was reading about how a silicone environment could have similar traits as a water/carbon one. Silicone can form polarized matrices.
