What I'd like to discuss in this thread is theories related to how the human race will advance, in regards to planetary expansion. This is important, because eventually, Earth will no longer be able to sustain human life. Whether it be caused by man, or natural events, Earth won't last forever. If the human race wants to survive, we must expand sooner or later.

I believe the first step is the colonization of the Moon. Currently, NASA is planning to create a Lunar Outpost, sometime between the years of 2019 and 2024. If this goes as planned, the colonization of the Moon will take a great leap forward. It may still be decades after the event that normal, everyday citizens, are able to live on the moon, and even longer until the colonies are able to sustain themselves; but the base of all future operations will have been established. Additionally, the colonization of the Moon will set the system by which nations claim land on all planets.

Will humans work together as one unit to colonize the solar system, and eventually the universe; or will future planets work the same as Earth, fighting amongst itself; leading to disestablishment eventually. If the latter is chosen, and nations are established, will they stay in collaboration with the government of other planets, or will there be no alliance between the human race?

I apologize for getting a bit astray from my topic of Moon colonization, but it's all very interesting stuff.

The next step, after successfully establishing a stable, time weathered Lunar government, is to colonize another planet. Most likely Mars. Of course, Mars is more likely to allow humans to live a life comparable to what their Earth dwelling ancestors live; due to its ability to be terraformed, while we are unsure whether or not the Moon could be terraformed.

Here is an artists interpretation of what a terraformed Moon may look like.

And here is the possible terraformation (word?) process of Mars.

Note the resemblance to Earth that the terraformed Mars has.

Scientists have also considered the possibility of terraforming Venus, which would be a much more difficult challenge than either the Moon or Mars.

I'm not going to get into the details of the process (as it's quite complicated), but if you would like to learn more about it the information is online. I will show you pictures however, showing the change that would need to be made. Something to note, is that due to global warming, Venus is the warmest planet in our solar system. Could that be the fate of Earth, after abandoned? Only to be once again terraformed and restored by another species, or the descendants of the long forgotten inhabitants of Earth?

Please keep in mind, that this entire thread is based purely on theories, some person, and that in no event should my outline be thought of as the end all, be all, of human expansion. It's simply what I believe may or may not happen, depending on events of the next few decades, and century.

I know this is a very long OP, so I won't go into detail about other discussion points, but I would like to point them out.

*Effect on humans, as a species? How would living on these planets affect the evolutionary path of humans?
*Will humans be able to achieve planetary expansion at all? If so, how far do you believe we will get?
*Will an alliance be made between all planets? How likely is it that the human race grows apart and eventually disassociates with the others as evolution and time goes on?

Your views on the entire matter?

I will not argue any further about global warming, since at this rate I will surely fail.

I think It will be possible to teraform Mars if we start soon some how (don't ask me how). The moon will be harder because of less gravity but at the same time easier because it's closer.

has nobody here a reader of Isaac Asimov?

alternatives: underground cities first, and from there outside.will work for mars and the moon

I know that eventually, the human race will have to expand to other planets because the way we have gone about living on Earth isn't within Earth's limits so sooner or later, we'll have move on.

I really just can't imagine people living on different planets. Now, I'm not saying it's possible but it's just difficult for me to imagine due to the fact that we've only sent men to the moon.

Heard of him, but I do not enjoy science fiction novels.

The caves of steel concept. However we are a surface dwelling creature, and we need sunlight, otherwise we might eventually mutate to be so sensitive to ultra violet light, that we will burn up to a crisp. We would be all bug eyed and stuff. We wouldnt be able to really leave. And yes, evolution, as slow as you may think it can happen, can actually happen very, very fast. Because if you think of it, something like a fly, can mutate, and evolve into something else in a minute. It is proven that humans can undergo this process after a few months.

Im nto saying this will happen, but it is highly likely if we ever take this idea to action.

what about when the sun dies?
how will everything survive then?

Everything? If there is life in other solar systems, avoiding the sun will be piss easy. Anyway, in about five billion years when the Sun does expand, the human race will be long gone.

Even if we can mutate ourselves (which is what I think you are trying to imply, and suggest it become a theory upon how we expand from planet, to planet), shifting all the people, equipment, gases, planets, water, food, etc. is going to be quite a difficult job. Not only is it a requirement we make biological advancements by technological advancements.

Okay, Global Warming is not a joke. If you had any form of modern education, you would know that. Ever seen the Inconvenient Truth?

Then again, when the ice caps melt, the world overheats, and everybody dies from pollution, I guess I'll have a reason to laugh at you when I become one of the last to survive on Planet Earth by hiding in my freezer.

1. I know that there are heating and cooling cycles, but seriously, the charts show that the levels have never gone over 300 ppm, and that now, they are over 700 ppm.

2. Carbon Dioxide does not help plants grow. It's what plants release when they rot...

3. Ice caps... melting... Al Gore... Any of this ring a bell?

Also, I think that we might be able to expand onto Mars sooner than possible. New technologies are being created everyday. Sooner or later, NASA will send like, 300 spaceships full of algae mixed with some super-growth formula made by nerds in labs. We'll have moved there by June. XD

I laughed. Plants breathe in carbon dioxide and let oxygen out, it's one of the arguments to negate deforestation.

Care to show us these charts? Also when the Ice Age happened that does not mean our atmosphere suddenly dissipated and left it into a massive freeze. CO2 emissions are not definitely the case-very likely-but not definitely.

Maybe polar bears and penguins evolved fire breathing?

Algae likes water. Water will freeze. Any plans?

It's not a joke, and it's not an inconvenient truth. It's an exaggerated truth.

Though there has been a slight shrinking trend over the past 30 or so years, but they've been growing slightly since 2007.

Also, the Sun is going through a higher-energy cycle right now. The polar ice caps on mars are also melting:

In 2005 data from NASA's Mars Global Surveyor and Odyssey missions revealed that the carbon dioxide "ice caps" near Mars's south pole had been diminishing for three summers in a row.


(from )

Some of the warming is from us, but there's another variable here, an there's evidence that the variable is the sun.

2. Carbon Dioxide does not help plants grow. It's what plants release when they rot...


I'm pretty sure a lot of plants breathe in carbon dioxide and breathe out oxygen. That's a major reason why air is more oxygen-rich in forested areas.

700? Yikes. I've only heard like 400. Could you please cite a chart? I'd like to see one.

3. Ice caps... melting... Al Gore... Any of this ring a bell?


That's not really a point . . . .

Also, I think that we might be able to expand onto Mars sooner than possible. New technologies are being created everyday. Sooner or later, NASA will send like, 300 spaceships full of algae mixed with some super-growth formula made by nerds in labs. We'll have moved there by June. XD


It'll still take a long time to change the atmosphere and general conditions. The biggest obstacle for Mars is that there are only small parts of it that would be safe anyway - Mars doesn't have a single magnetic field. It's pockmarked with a bunch of small ones. To prevent solar flares from totally creaming any civilizations, we'd need to colonize in those small magnetic fields.

It's hypothesized that a planetoid or Pluto-sized asteroid hit Mars and scraped off a lot of its terrain (Mars has a lopsided shape, including a completely flat area where the asteroid could've hit) which would've thrown off the rotation of Mars' core and therefore majorly disrupted the magnetic field.

I'm not saying global warming isn't real, I'm saying it's exaggerated. Also, only global warming. Other aspects of climate change, such as deforestation, the plethora of endangered species, the hole in the ozone layer, and the increased amount of CO2 in the atmosphere can't really be anything besides us.

Sorry, I'm tired as sh*t, and I failed here. I meant to say:

Please ignore this part in my post. I didn't mean to copy and paste it. Sorry D:

It's hypothesized


*theorized

(It's been solidified as a theory now, I'm pretty sure)

Okay, I think I corrected all my fails now.

lol. Okay, I made a mistake with the 700 ppm thing. That was the level scientists say will be reached by 2050. Just made a teeny-tiny-mistake. the current level is at 385ppm.

Also, about the plants part, I'm pretty sure that plants do not need Co2 to survive, it's just nature's little added bonus. Though I could be wrong.

you cant build an atmosphere


It is possible to create an atmosphere if the planet is small enough in the future they could build gravity mechanisms and plant plants supplied with light water and carbon dioxide and fill the atmoshphere

Lol. If it was 700 ppm, we'd probably not be doing so well :P

Yeah, 385 ppm sounds right.

According to yahoo answers plants pretty much do best from 300 - 2000 ppm, meaning that they do to a certain extent, but after a certain mark they stop benefiting. However, they apparently don't get any ill effects until they hit over 10,000 ppm :O
