There is another fact that puts a damper on the speculation of life elsewhere.
After decades and decades of high level research humans have not been able to create life in a lab.
FALSE
Goddammit, you stupid fucktards keep repeating that LIE.
It's been done in the laboratory from scratch FORTY times already.
There are already three brand new species because of it, that never existed before.
Stop with the bullshit, 'kay? It gives righties a bad name.
That means that the creation of life is extremely complex. The more complex it is the lesser chance of it being elsewhere.
We may have won the lottery here on earth. Whatever the number of factors that must have some together to produce life we got them here on earth but that doesn't mean life is elsewhere. If the universe is finite then it will have unique things in it. We may be unique with life.
Then on top of the creation of microbial life we have some very unique things on earth hat allowed advance evolution. That didn't even happen until the earth was four billion years old.
Please refer to my other thread. You can see graphically how it works in real life.
We now have AI and neural network models for these things. In the brain, pushing a neural network into criticality gives it 50x the speed and 2000x times the memory.
In a segment of DNA,
one change in a base pair (a "point mutation") can push the entire system into criticality.
I mean no offense, but you need to hit the books. This is not your father's science. Criticality is extremely complex, so much so we can't even tell what we're looking at most of the time. However we can pick up fractal and power law signatures that give us clues.
Science is TODAY, not yesterday. Yesterday, Craig Vetter and his colleagues created a minimal life form from scratch in the laboratory. They synthesized all the DNA by hand (or rather, by machine). There were ZERO components from existing living cells. This science has been replicated hundreds of times already, all over the world.
Today, biophysicist like me are revisiting micelles. We have now catalogued all the different ways proteins can embed themselves into cell membranes, naturally forming trimers and tetramers by adopting their lowest stable energies. All this occurs through SELF assembly, humans just put the right number of molecules into a beaker and the rest happens by itself.
Life is a natural and inevitable consequence of the fabric of spacetime. There's nothing magical or mysterious about it.
