A allready read these kind of things earlier.
All I can say is that we will have to wait to get the answers
I think if they can solve the problems that can prevent us from going
into space there is a good chance it might happen ones!

As much as I love the idea of mankind eventually existing mainly on another planet...

But i dont think its practical.

Just think, we have not yet discovered a planet that we can breath/live on, without life support...
And also, if it takes so long to get to mars, or any other close planets, just think how long it would take to get to a planet so far away that it was undiscovered...

The only practical way of moving mankind to another planet, would be to have a huge ship full of people, practically creating a new civilisation while travelling through space, many generations would grow and die, before they even saw a inhabitable planet, and when they got there, the new human race, would just slowwly develop - atlest, you'd have thought so....


But the amount of fuel it would take to launch any kind of rocket or space craft, that far, while carrying that many people, would it be possible??

But i think that space tourism will come along in the next century or two (hopefully while im still alive!) and that will slowly evolve into living on other planets....

I think and hope that the future of menkind is outerspace. But I believe that is very hard to happen for 2 main reasons. First of all the technology isn't ready yet. Maybe NASA could risk a few astronauts, but for a viable way to sustains hundreds or thousands of people that is another story. Not to mention millions or billions... That kind of research takes time, time which I'm afraid we don't have. We all can see what we have done to the world and it can't take a lot more till it won't be able to sustain us... On the other hand there is the problem of competition, or to be more precise the lack of competition. A huge progress was done during the Cold War (I still don't believe we landed on the moon... but that isn't important nowadays since today we can go to the moon) so without some kind of competition research won't be fast enough. And once again, I'm afraid that can't be done without a war.

We definitely need to continue our research about space before we will be able to live off our planet, but right now there are more pressing areas for researcher's time and money, so it may not come for awhile. At the same time, however, we are multiplying to beyond what our planet can sustain, and we may soon deplete it of the things we need to live. As this occurs, researcher's shift may focus. Either we will need to find a way to make this planet continue to be hospitable, or we will need to find a way to make somewhere else that way and live there.

Reading Orson Scott Card's Speaker for the Dead series offered interesting insight to what it may be like if we begin colonizing other planets. Of course it is only fiction, but it gets you thinking. In these books, different cultures went to different planets. I wonder how we as a species will change if we were to isolate ourselves in groups on different plants. Perhaps we would evolve into different species, which could create many issues if we decided to merge one day.

At this point, there can only be speculation about a future in space, but it is still a fascinating subject to consider!

No we will face problems more than here. Gravity, and carrying our Oxygen , water and food.

We went only to our satellite the moon. there are long way and need time and exceeded the speed to go to the next neighbor , Marc. It is not practical.

We know that human and our plants and animal can't survived without water, oxygen and food so we need to carry oxygen, water and food.. So to live in space we have to find planet that is a exact duplicate of our planet and as said the 200+ planets found so far none have come close to earth. So even though will find that similar planet it need 100 or more of year to travel there .


If we decide to go to Marc it will take 10-15 years but we need to carry our oxygen, water and food.

If we decide to live in the moon because of affordable travel time, we need to carry our Oxygen, water and food . So better to live in earth's deserts or or at pole in snow than living there.


No it is better to put the effort and money here to discover more resources or new technologies.

If we used these trillions of money and the huge research time and effort in developing resources in our planet , it will be better.

It is better to use these budgets and manpower and human minds to discover more resources or new technologies: to deal with diseases, hunger, global warming,

We have to find cost effective methods to convert water to water suitable to human and then planting the desert.

- we have to use natural sources of energy effectively and less cost than now as Solar , hydrol and wind energy.

-We have to think how to increase the food products.

- to planting deserts

- we have to use and increase sea food.

- to produce cars that less consume fuel and less transmit carbon dioxide.
- to think about renewed the consumed energy.

A Don't worry. Malthus one day was pessimistic but human survived for more than he predicted. The Reverend Dr Thomas Robert Malthus who lived from 13 February 1766 to 23 December 1834). has expressed views on population growth and noted the potential for populations to increase rapidly. He said that the population grow if unchecked in geometric rate rate (i.e. 1, 2, 4, 8, 16, etc.), whereas the food-supply grows at an arithmetic rate (i.e. 1, 2, 3, 4, 5 etc.).. So he predict a biog problem and suggested that only natural causes (such as accidents and old age), misery (war, plague, and above all famine) disasters. . But the crises didn't happened . or sometimes happened for a while.. [see Wikipedia, the free encyclopedia to know about Mathus and his ideas]at http://en.wikipedia.org/wiki/Malthus ]

Moreover The space shuttle are extremely expensive. And you will not enjoy that European or American living as you said and you expose them to known and unknown risks. .

As I am not that into this kind of topics but I have a personal opinion (though an amaterish one ), I want to say that I think the problem with the mankind is that we can't handle our own world (wars, oil etc.) and we want to handle the universe tourism seriously.
I say, lets fix the problems in our world first, and then (possibly) create problems in other worlds in the galaxy.

Well I might be an amateur in this subject too as I agree with White Eagle. We are no where near to understanding the depths of complexity that our world is in right now, but we go out thinking that all of out problems will be solved. We are hopefuls, thinking that if we forget what is going on at home and venture into neighboring soil, we may find a better and easier way out of our issues than looking in our own homes.

We can see this pattern through out history, where the European countries wanted to colonize and spread their reach before they fully grasped the problems back at home. Instances such as the inquisition and the French Revolution go to show that Europe was in a fair share of chaos, for such occurrences to rise, but they insisted on expanding their horizon through the Earth. We are greedy by nature and not patient, thus often we find ourselves unable to bring forth enough patience to solve the problems within, and instead we go out to blindly search of the wonders without.

Quite frankly, I believe once we have found a solution to Global Warming and a solution to the threat of nuclear war, then we should begin thinking about Mars. If we can not handle Earth, how can we handle Mars?

Do I believe that our future lies in space?
Absolutely.. for one simple reason, if we stay here and do not venture into space, we are going to become extinct, and that is a certainty.

There are billions of years of life left for this world, our star is relatively young, life on our world is robust and pervasive, and one of the most successful kinds of organism, the Dinosaur, lived for many hundreds of millions of years.
But it they had a major problem, as do we.. one rock out of space and we are just as dead as they all are.

I often hear people say that our end is the natural way of things, life moves on and the planet renews itself.
Let me just rebut that with the argument that we are the only true intelligent life forms, that we know of, that have ever lived, or that are alive anywhere in the universe (that we know of).. sure, Dolphins are pretty smart, so are Chimps.. but only Humans have walked on another world, only we are capable of taking ourselves and by extension, the rest of the life forms that we depend on to survive, to another world.
Think not just about our own kind, think about what we can do for all life? It is possible for a sufficiently disastrous cosmic event to wipe out all life on Earth.. no second chances, no reset button.. end of the story of life as we know it.
I am not nihilistic enough to view that as anything but the worst kind of tragedy, and I have trouble understanding an opposing view to that sentiment, although I am sure there are a few who would say "We have no choice".

I think survival is not only central to ourselves, it is our place in the scheme of things.. we are here to live, to be a part of life and to understand life, and more than that, we are here to protect and nurture life.
I mean look at us.. we are a relatively fresh species on the planet, and yet we are unlocking the very building blocks of matter, the source code of life itself and we are very close to unlocking methods of producing clean, renewable energy sources on a wide scale. We can communicate with each other planet wide, we can live in nearly every environment thrown at us, we take active steps to preserve and protect other organisms, even those which are our predators (such as Tigers).. we have the means to take life and transport it through space, deposit it on another world, and nurture it to grow, adapt and start an entirely new ecological system.

That automatically doubles our chances of long term survival as a species, and the same goes for all the other species which depend on us for survival.
Without Humans, where would the cats and dogs be now? What about cattle and wheat? Vegetables and fruits?
The plants and animals we depend on, also depend on us.. we are the best thing to ever happen to the cat, thats for sure.

What problems do we face?
Many, its true, but that will not stop us.
We are driven by the need for resources, foremost, the economics is not the limiting factor, it is the driving factor.
Our thirst for rare metals and fresh water, for new territory and for the strategic advantages of space will drive private industry and the new industrial giants to press out into space. Innovation thrives on conflict, and the struggle for resources is something we can all feel... every time we fill our gas tanks or buy those bottles of water.
Who would have believed, one hundred years ago, that we would be buying bottled water?

We have theories on increasing the speeds we can reach in space.. I think the best I have seen so far estimates a maximum of 70 percent of light speed, using a hydrogen ram jet system, collecting hydrogen from space with a magnetic scoop.. but lets not forget that we could propel craft around our own Solar system, just using the energy of the Earth and the Sun.. imagine pushing a space vessel using a laser?
We can build systems to grow food and recycle water, but we need to iron out the kinks and get serious about it.. we need to fully utilize genetic engineering to unlock the power of living technology.. it is not impossible to imagine a living space vessel, at best, or at least a contained ecosystem of highly refined, engineered species, tailored to all of our needs.
This requires a lot of water, and water is one of the best insulators against impacts from micro meteorites and the hard radiation of space... a handy coincidence.
What a pretty sight it evokes.. a massive vessel, coated in bright, shining ice, with a green heart of verdant forests and productive, courageous people, traveling the vast voids of space.

I want Humanity to survive, and one day, to be so far spread and independent, that no cosmic disaster can ever kill us all off in one horrible moment.

Call me an optimist, but I think it will happen.
