With the exception of Khrono, most people here are missing the point.

This is not something we are going to be doing tomorrow. The technology required to colonize the galaxy is centuries, maybe even millennia away.

This is not about the short term mistakes we are currently making. If those are to be our downfall then we will be extinct long before we leave this rock. IT is if we come through these tricky times that we will need to expand amongst the stars.

The end of the sun is a bit of an irrelevance, there are 4 billion years before that happens, if we aren't already amongst the stars by then it will be because we are already extinct.

The real issue is population. One planet can hold only so many people. Once a species can expand no more it will stagnate. At some point we will need to expand through the solar system and then beyond. Just as fish left the sea to occupy the land we will leave this one world and become a star fairing species. We will take the most important evolutionary step any species on this planet has made in billions of years.

Whilst these steps are still a long way off that doesn't mean we can't slowly move towards that point. As Confucius said, "a journey of a thousand miles begins with a single step". We need to continue exploring space. We also need to continue to train our telescopes on the sky. We only confirmed the the existence of a planet around another star in 1992, in the 20 years since we have discovered more than 760. There are billions of worlds out there waiting for us.

Carl Sagan described the human race as "a way for the universe to know itself", I agree with that. I would suggest that the pessimists, the ones calling for an end to the human race, are part of the problem, not the solution. Our future will, I hope and believe, belong to those who look to the stars and dream. We have amazing potential. We have minds that can understand the structure of the smallest sub-atomic particle and the largest galactic cluster. We have engineers and architects that can produce machines that can fly us to the moon or construct vertical cities where you can look down on the clouds. We have doctors that can fix broken bodies and cure once fatal diseases. We have artists that with coloured chemicals or a piece of rock and a chisel produce works of awe inspiring beauty. We have musicians, authors, cinema. We are amazing. We deserve the universe and the universe deserves us.

The first sentence in the OP set the tone for what most had to say, though.

Quote

Finding planets outside our solar system that can sustain life should be made a top priority, say Australian astronomers.

It's extremely hard to entertain the idea of taking a micro-step toward a goal when we have pressing current problems that if not given precedence, well, we will be extinct far before we leave this rock.

As I said, missing the point. Context is important here, this was a group of astronomers writing in a journal for other astronomers. This was NOT a call to make this a priority for mankind, but a priority for astronomy. Very different things.

No it's not, it's very easy to entertain the idea. Mankind is capable of multi-tasking. It is not an either/or situation and no one is saying that we should do this INSTEAD of trying to sort out our problems.

Most people here are missing the point.  If the human race confines itself to one place...one planet...it is guaranteeing its long-term extinction.  Major extinction events happen, on average, about every 100 millions years.   Some are as short as 35 million years and its been about 60 million years since the last extinction event.  It could happen anytime...perhaps an eruption of the yellowstone supervolocano tomorrow triggers the eruption of one or more other supervolocanos in the next year and life on earth is practically eradicated.  Perhaps a supernova blows up on our side of the galaxy, or perhaps the earth gets radiated by a pulsar blast originating from an event that happened 600 million years ago in a neighboring galaxy, or the earth in the way of a cosmic superhighway and alien regulatory bodies have just given the go-ahead for our demolition in the interests of faster commuter routes.

I'm not saying we need to pack up and move tomorrow, in fact we won't  have the technology to do so for a couple of hundred years. But it is a goal we should be working towards, while at the same time trying to make our home planet a better, more sustainable place to live.

The sun will eventually blow up in 4-5 billion years, but if we stay on earth, humanity would be long extinct by then.

Good posts Waspie and Horus, Its a shame that humans dont live long enough to see the results of their endeavours,but our kind (barring accident/oblivion by ourselves)will one day go to the stars.

(2) try your second best, ........if that dont work

I would love to see these things come to pass as much as the next man, but as a species we seem to have become very impatient and short sighted. This was not always the case, in fact it is a recent development.

All around Europe you will see amazing cathedrals. These were at the cutting edge of technology in their day and they took generations to build. People were prepared to design and work on constructions they knew it was unlikely their grandchildren would live to see completed. They did it for the glory of God. Now even as an atheist I find that dedication awe inspiring. If we could find just a fraction of these people's vision and dedication, look towards the future and start building for the glory of mankind then our species future amongst the stars would become inevitable.

Agreed Waspie, The people them days did seem more dedicated,but they didnt have the problems todays people have,like going 20/30 miles to work in "rush" hours,no mortgages,but they did pay rent to the local Land Lord and of course Money,which seems to be the "thing" that everyone hasnt enough of..

Maybe that didn't have mortgage payments and traffic jams to worry about but they did have famine and plague. I know which I would prefer.

i think it would be wrong to take those things out into the cosmos..

i think the human is quarantined on earth for those reasons..

i think many people are missing the point, but starting to get it..

I'm really not sure what the point is that you think  people are beginning to get. So I'm afraid I'm going to have to inject some reality here and repeat myself.

We are not going to be able to leave this planet for centuries. If the problems are as bad as some are claiming we will be long extinct before then. If not then we are likely to have gone at least some way to solving them. Either way your argument is an irrelevance.

As to being quarantined, what nonsense. We are not quarantined, we just don't have the capability to travel amongst the stars yet.

How do you propose that is done? Who chooses who can breed? That way lies totalitarianism, stagnation and eventual extinction.

Wow ! THis is where Space meets the Place ! Were soon to not even need to worry ! THe clock is running,Humans will need to evolve quite a bit before we even try to move off planet ! Tech, social,which is all in the Mental part of our new needs on this world.
Maybe we really could use a mentor ? Call Earth E.T We need your help ! :innocent:

This is a Work in Progress!

I don't mean to come across as a pessimist but i'm almost positive we will be long extinct before we will need the sustainability of a new planet. people as a whole are impatient, arrogant, ignorant and completely driven by the material world. i look around today and i see billions upon billions spent killing each other off while more die hungry, i see religion poisoning the minds of the short-sighted and spreading ignorance, and i see people in general who when it comes down to it don't give a damn about the next man and will crap on your grave if you cross him. the human race is destructive and greedy. we ARE a virus and although we have done amazing things we have also done and continue to do truly horrible things that i feel in the end will lead to our demise. we are still extremely primitive and things are only getting worse. hell if we didn't have law enforcement people would be literally killing each other in the streets. wait, they already do. how can a race that doesn't respect themselves or their environment be capable of going out and preserving themselves. it can't and won't happen. i realize i come across as very narrow minded but i've had faith in humanity for many years but at this point i just want a rock to come along and smoke us all into oblivion. do not take this as a reflection of my character cause i'm an honest and caring person, i may be very opinionated but i would give the lesser man the shirt off my back if it kept him warm. that doesn't change the reality of things though.
