And it's all gone quiet..
Well, they certainly know that the building blocks for life (amino acids) are easily found outside of this planet, and that life started relatively quickly here. Proves nothing, but "suggests" it's not too difficult. We're not even certain yet that there's no life on Mars, and that's pretty damn close.
As for "purpose". There is none, of course (IMHO).
I agree that I believe that there is no purpose to life. And who says that all life has to be formed using the amino acids we know? Why can't they be sulphur-based? Sulphur can also form 4 bonds like carbon.
EXACTLY. Similarly, atoms are made of protons and electrons and neutrons and stuff. But what are the protons, electrons & neutrons made of?
Mind blowing.
Electrons are fundamental particles, that's to say they are made of electrons, and not any smaller components.
Protons and neutrons are regions containing quarks:
A proton contains 2 up quarks and 1 down, a neutron contains 1 up and 2 down. Radioactive decay occurs when a quark changes from one type to another.
A scene from the film Contact blew my mind.
In our Galaxy alone there are over 200 billion stars.
If one out of every million of them had planets
If one out of every million of them had life on the planets
If one out of every million of them had intelligent life, then there would be millions of civiliations out there.
That doesn't seem correct? 200 billion times a millionth times a millionth times a millionth is to the order of ten millionths, not millions of civilisations? It might work with hundredths rather than millionths.
ANother mind blower, our nearest neighbouring star is 4.5 light years away. My understanding is you would have to travel 4.5 years at 56,000,000 mph to reach it. It is just one of 200 BILLION stars, and out galaxy is one of 200 billion galaxies.... cool or what
It's even more than that, the speed of light is ~186,000 miles per second, or ~670,000,000 miles per hour. Mind-blowing!
Darwinian evolution is incomplete, which is essentially why it is still considered a theory.
One of the biggest problems is that the "random mutations" have never been observed. If it were true, you would find countless useless physical traits in life forms that randomly mutated but have no specific purpose like you suggest - but we don't. There are various "evolutionary scars" such as the human tail and wisdom teeth - but they once had a purpose in previous existences.
How often do you see a lifeform reproduce, only to find it had randomly mutated an extra leg, or perhaps gills, or anything else - Never.
If a life form did develop a "random mutation", more often than not the life form would survive even if the mutation were a hindrance - and so we would be able observe these "random mutations" in every life form on the planet today if it were true.
It is clearly not a case of trial and error. Life evolves to survive in its environment by adaptation - this is very specific and can be seen amongst even the most recent of known life forms. You won't find a single trait in any species on the planet that doesn't serve a purpose - doesn't appear very random at all.
I'm going to pretend I didn't read any of that, I don't want to have to quote my ENTIRE biology textbook to prove you wrong.
