Who is to say? |
Who is to say that if there is 'life' on some satellite far far away it
will be like that which is found on Earth? Wouldn't it be more likely
that this 'life' would be composed of other elements or that the
necessities of life here (water, oxygen, carbon dioxide) will not be
the same elsewhere? We always see depictions of aliens on television as
little green beings with two eyes, two ears, arms and legs, and so on.
This shows our bias (non-scientific of coures) towards ourselves and
not objectively to consider that it could be completely different
across the universe. Are we not finding 'life' because we're not
looking for it correctly? I look forward to the discussion.
Thanks

Trees, potatoes, a virus and seaweed. Define life.
Not really a physics topic, is it?

Why, the subject has been discussed to death.
Essentially, basic chemistry says anything other than carbon based
life is highly unlikely, and for most other elements, impossible.
