Alien life: myth, fantasy or reality? We don’t know but it’s one of the mission goals so I decided it was time to define life and what to look for
What is life Edit
According to the modern biology something is alive when it can grow and reproduce this discussion of life is not yet over especially this things that count for just a few creatures. Can we make it even harder for them to settle on a concrete definition of life? Yes like teachers always say harder isn’t the challenge making a test easier is the hard part! What is this alien life form lives for a million years, is bigger than mount Everest, lives in empty space and doesn’t move. This type of life form can be seen as a meteor or even a small planet. Or what if this life form doesn’t grow, according to the definition it isn’t alive anymore. Now we are looking for bacteria rather than a human like creature.
What can we expect? Edit
If after a six month journey we finally arrive on mars or any other planet, the big question is what to look for? How do they look? The first question is relatively easy because the first signs of life are bacteria like creatures, but is that the first ting to look for? Or is this something earthlike? Well so far so good one question solved 2 new. So in order for a plant to support life there must be things like a good atmosphere but ones again we don’t know what they breath. A another thing for life is something to eat/drink or any other form to stay alive this shouldn’t be to hard to detect, just look for the local groceries store, ok the local river/lake is ok to. Still the easiest would be is the life forms just came to you just like a dog.
A another thing that we take for granted is life is carbon based but silicium is also a chemical that can make some very complicated molecules, the big different is that silicium can only do it’s thing in for humans extreme conditions.
What are the chances of alien life Edit
Ofcourse I’m not the only one who ever tried to calculate this so I decided to keep the drake equation: N=R* x fp x ne x fl x fi x fc x L
fℓ is the fraction of the above that actually go on to develop life at some point
fc is the fraction of civilizations that develop a technology that releases detectable signs of their existence into space
L is the length of time such civilizations release detectable signals into space
according to NASA data these are the accurate numbers:
N = 10 × 0.5 × 2 × 1 × 0.01 × 0.01 × 10,000 = 10
So now you know it 10 civilizations. That’s not much but be careful this number is just a indication of intelligent life that is capable of communicating with us so if you take those two variables away:
N = 10 × 0.5 × 2 × 1 × 10,000 = 100000
Suddenly the numbers are much better.
