You don’t want me to answer this question. You are looking for a great, positive answer that will make the future look bright not only for colonies on these places, but an economic base for those colonies.
Meanwhile, I’m going to say I don’t think there’s much justification even for people walking on Mars when our robots can do it more safely and less expensively and achieve the same or better results…. what to speak of “colonies.” I think it’s almost laughable and mostly just science fiction dreaming.
People may or may not one day walk on Mars at great risk, and some will probably die in the attempt. There is little reason to go there from a scientific point of view other than to say we did, just like we walked on the moon and then went away.
In the meantime, a safer, cheaper way is send our machines to go.
You see, what this is all about is finding life. What scientists want to do is prove that life can evolve elsewhere than Earth – a so far unproven theory. We want there to be life elsewhere because we want to prove that life was not “created” on Earth alone, but life naturally develops from matter when conditions are ideal.
We don’t need “colonies” or economic bases in space to prove that. We just need to find some germs under some rocks or on some moon around some planet in our solar system. For that we just need space vehicles and robots like the Mars Rovers.
Whether we find life or not is anyone’s guess, but it is still science fiction thinking we will colonize anything off planet.
Pretty much all of science and scientists in the world believe in extraterrestrial life, even though no evidence of extraterrestrial life has ever been found to date. Why do scientists believe in extraterrestrial life? Simply because there are billions of stars in the Milky Way galaxy and billions of galaxies in the universe. Somewhere it is highly likely that extraterrestrial life exists. It is even possible that extraterrestrial life of some form or another exists on Titan, within our own solar system!
I don’t see either as being dependent on the other. In other words, you can believe in God and not in extraterrestrial life. Many religious people do in fact hold that view. On the other hand, you can believe in extraterrestrial life and not believe in God. I know many people who hold that view.
So I don’t see a paradox at all. According to the Google dictionary, a paradox is “a seemingly absurd or self-contradictory statement or proposition that when investigated or explained may prove to be well founded or true.” I fail to see a contradiction that two different people can hold either view. It’s all theory.
In reality, we do not know for sure that life exists anywhere other than Earth because we have never found any evidence of life, although we continue the search. We have yet to find even a fossil of a microbe from space. However, the laws of mathematical probability suggest that with billions of planets in this galaxy and billions of other galaxies, it is likely that there is at least microbial life somewhere, if not something more advanced. We just haven’t the proof yet.
Similarly, except for subjective experiences, there is no proof that God exists either, although people believe that God exists. Maybe both exist. Maybe neither exists. I suppose it’s a question of faith in either view.
Well, let’s not put the cart before the horse. Right now we don’t know for sure that any life exists anywhere other than Earth. We suppose it does by mathematical calculations, but we haven’t even found a fossil of a microbe from space.
Secondly, suppose there is some super advanced civilization (your use of “exponentially” doesn’t seem to make any sense), the reason they probably haven’t completely colonized the entire Milky Way Galaxy is that for them, as for us, the laws of physics make it pretty much impossible to achieve interstellar travel because of the vast distances involved. And even if they could colonize some surrounding systems by now, it would take light and radio waves 100,000 years to reach us from the other side of the galaxy.
It’s all about proving each other is wrong. It permeates the entire political sphere. It determines policies of U.S. Presidents, the Environmental Protection Agency and so on. It’s about trashing Earth or saving it.
So who is wrong, who is right?
Philosophy 1: God created Earth – perhaps as recently as 4,000 years ago. With the creation the entire fossil record, stars, planets, life, life forms, species, were all created simultaneously. God created Adam and Eve. We all descend from them.
Philosophy 2: The universe started with something like “the Big Bang” about 14 billion years ago. Life evolved from chemicals and is likely to be found on other planets than Earth.
Religion historically has found science a challenge and – for example – convicted Galileo of heresy for saying the planets orbit the sun. Science has proved religion – in this regard – to be wrong.
However, no one has proved that life has evolved from matter to date. No one has found life on anywhere than Earth. Religion says God created life. Science says chemicals created life. Neither has been proven.
To date – no one has found evidence of life developing on another place than Earth.
They would like to.
That’s what it’s all about.
We don’t know. Some people think we know, but a real scientist will agree with my first sentence.
The theory, still unproven, is that life evolves from dead matter. We’re still searching for life on other planets to prove this wet-dream of scientists, but still we have no proof of concept – just a concept – to the chagrin of science. We are frankly disappointed we haven’t found life elsewhere than Earth.
Evolution starts with creation of stars that create elements like the ones we have on Earth. We think when conditions are right that the chemicals develop amino acids (this is proven), which are the basic building blocks of life.
From there, eventually by combination and permutation it develops into something that could be called life.
Again it’s not proven but widely accepted. We don’t know for sure, hence my first sentence.
No we are not alone. There is life out there on other planets. Don’t make me prove it. Just accept the premise. Life exists elsewhere than Earth. Life is one thing. Intelligent life is another. There’s intelligent life out there too. The problem is this. We’ll never know about them, and they are out there and will never know about us. This is the sad reality. Now. Why do I say life is out there don’t make me prove it. It’s because of underwater volcanoes on Earth. We have these volcanoes under the ocean, deep deep volcanoes. They are erupting and giving off heat and they are surrounded by organisms that can’t be found anywhere else on Earth. There’s no sunlight, no photosynthesis – just the heat of the underwater volcano. The same thing goes on around in other places in our solar system so we are to think there is life elsewhere in the solar system. Just not so bright. Can’t type. Don’t have computers. No Internet. No smartphones. Just a microbe. Somewhere, however, there is somebody else. Another civilization of civilized beings that have found a way to be self-aware. Big problem though, because we’ll never meet them, know them, visit them, and vice versa. Space is so big, so large. By the time our sun dies and Earth is consumed, our radio waves will still be going out there. We are here. We are alive. We can put our fingers on a keyboard. We are intelligent life that can do more than beavers building a dam and we are doomed. We can’t go anywhere, star trek be damned. Our sun will blow up and life here will be extinguished. What’s the point? Well, we do exist. That’s significant. We exist in the here and in the now. We’re stuck on this rock called Earth. Does it matter? I think so! What to do? Well, I think we need to make a mark. Voyager was a great idea. There’s two satellites that are so small nobody will ever find floating out in space with information about our civilization. Thank you Carl Sagan, but it was done just for funding. Nobody’s going to find Voyager 1 or 2. They are specks of sand gone to eternity. They will out survive us but they will not be found or noticed. We should, however, be noticed because we mean something. We are here. We were here. We should design something to make our mark on the universe. How can we do it? Intelligent life please respond.
