Carbon based life. Si(licon) has four outer electrons like C. And can tolerate high temp. Keeping an open mind, we cannot rule out that lifeforms MUST be based on carbon. But for simplicity sake, I will go along with Carbon.
The thing about life is it is finite. Otherwise it won't be life, it'd be something else. Because our life is finite, we must treasure the things we can attain, feel, or experience during our "lifespan." Maybe someday we will find a way to travel through a wormhole and arrive somewhere else lightyears away, that is if we can construct a vessel that will survive the forces in this wormhole. Let's take it one step at a time. If the US, Ruskies, Chinese, or a joint-venture comes up with a spacecraft that can make it through the asteroid belt, then we have something to look forward to. But for now, we have only the earth. In my lifetime, I am only hoping we preserve the planet and not pollute it any more than we have. If this were there case, Hybrids will be selling better than multi-cylinder SUVs; but I don't see this happening. So we can rule logic and ration out.
Yes, we need to find another planet. And we will. But how are we to get there? If the Vulcans don't help us, will the Klingons or Romulans? Back to the drawing board.
Bud, let's learn to live with what we got. And so far, capitalism isn't getting us there. Steven Hawkings is brilliant, but he doesn't influence the world.
Cheers!
Well the only life humans know are on this planet, so we extrapolate to other planets as well. All life must be carbon based and there must be presence of water. Of course, there might be life that don't require either of those elements.
We already have the means to live on Mars or the moon.
If we can have men live in space for years (the ISS station), which is very much harsher, we can build houses and communities on the moon or mars easily.
We can build big buildings there with ventilation systems that provide oxygen. The windows can be coated to reflect UV rays from the sun. Humans can only live inside these buildings of course, they cannot go out because they will die of lack of oxygen and the uv rays from the sun will burn their skin as well. There is gravity on these planets due to their mass, so humans can walk around as per normal.
The technology is there. We can do it if we want to but we don't but it is meaningless and costly that is all.
What we are looking for is a planet that can support life without us living in a capsule or a big building.
The nearest possible ones are a few light years away, meaning we will never get there with current technology. There are a few moons of pluto that look promising, we have yet to explore them. But they are very small anyway. We do have the technology and means to build communities on the moon or mars, it is not far fetched, it is reality. We have men living in space right now for years at a go, without gravity. Google the International Space Station. With gravity on these planets, it would even be easier to carry out daily life.
Wormholes? That is too far fetched.
Life is finite? Most probably but I believe humans can live for hundreds of years if we work on it.
If I could say put my brains onto a metallic robot body, I would be able to live for hundreds of years. It is far fetched and high technology but since we already have fake hearts pumping blood in humans today and fake arms and limbs, it is not that far fetched is it?
Cloning would also be quite fascinating in this respect. Too bad the idiots are trying to prevent cloning of humans. I say we clone humans because we don't want to die.
