I thought I would make a thread about people’s opinions of the long term future of Earth and the Human race.

I thought we could debate some the biggest questions that could affect all of our futures

1.
Earth resources how long do you think they will last, Will we be able to create stable nuclear fusion in time?

2.
When is the next world war likely to happen will it be a nuclear war? Would this be the end of the human race?

3.
Humans colonizing other planets is going to start happening in the not so distant future with the first human settlers planed between 2025-2040. How many human will be on mars or other planets by 2100?

4.
Can Earth support the ever growing human population, will humans see the year 3000?
 
1. For long enough not to worry.

2. No idea. Probably won't happen any time soon.

3. Hopefully quite a few! A lot can happen in that time.

4. Not at current consumption levels but if we're smart (which, in general, we're not) we should be able to.

That is not going to happen anytime soon, certainly not in our lifetimes.

I don't think 87 years is an insignificant amount of time.

Who is going to get the ball rolling? America is not at the moment and nobody else has anywhere near the technology or the need to do it.

We will have to at some point though. The human race will need it to happen to continue once we have killed off our planet.
 
There's a HUGE difference between a manned mission and colonisation though. It's comparable to inventing the wheel and claiming cars are on the horizon.
 
The technology is there( or will be in about three years when either NASA have their SLS or Space X have their Falcon Heavy), it's cost that is the issue.

The future is bright, resources are fine, world war is very unlikely.

Also can't rule out the affect Skylon should have on cost and the impact of 3d printing in space.
~80 years is a huge amount of time. Think what tech was about 80 years ago.
 
Well first the population needs sorted out, a massive cull of the dossers who breed like rabbits and give nothing back to society:p

Seeds are being sown though. Whilst we're not attempting to go any time soon, there is a fair bit of research being done.

I imagine it'll be a joint effort.

No prayers will save you when you're vapourised by a nuke.

Over recent years space travel has grown as an industry. Mainly with companies like SpaceX beginning to break into the industry. There definitely appears to be an ever growing focus on progress.

It just feels much more like we are heading back into the years of progress in space travel compared to the past 20-30 years.

1. No
2. 2051.7
3. ~31
4. Yes
 
The underlying problem we face is that of cheap energy. Glaucus can probably explain more about how we're tackling that. Once we sort that we're laughing.
 
Thinking about question 4 the population is currently around 7 billion people. If it keeps rising and we make it to the year 3000 I would take a guess that the human population would be around 1 trillion.

The only way I think we stand any chance of supporting that amount of people all hinges on if we can get nuclear fusion to work.

China are making some promising advances in the area, they certainly have the money. If China starts making serious advances in space exploration, or decides to build a base on the Moon or Mars, then I could foresee another space race.

Agreed with the second point. We have all our eggs in one basket while we remain on this rock.

It's not just energy though, How would we feed all these people.
