Is Venus humanity's next home?

[XenoEnsi-14]

what about effects like volcanism and quakes??

Would be dealt with the same way it's being dealt with on Earth, and probably wouldn't be that much of a problem for about 1,000 years. Structures would most likely domed or pyramid shaped.

1. has anyone actually seen or measured the oort cloud??

It's estimated to have five times the mass of Earth and mostly be ice.

i believe the near-future and future main source of electricity would be via generators based on "sterling engines", whose only two requirements are working gas and a heat source...


the heat source on mars can be... (a). biofuel ( renewable ), (b). petrochemicals ( from titan ), (c). nuclear material ( plutonium, whenever available ), (d). simple solar concentrator.

For common folk yes, A. and B. for short term then D.with fusion for long term, fission of plutonium is more dangerous than fusion of deuterium so that won't be likely.

we should be a more gentle humanity, using technology only when absolutely required... that is sophistication. i am much inspired by the minimal high-tech in the dune books by frank herbert.

We should be more gentle to each other, but in reality majority of people are materialistic. Minimal high-tech can only go so far, you need high tech for travel in between planets and large projects such as terraforming and growing planets.

i don't know what "ige" means... microwave??

Induced Gamma Emission, spaceship propulsion would likely be ion drives powered by a nuclear fission/fusion reactor.

there is no real reason not to.

Aggravating the rest of the world is a perfectly good reason not to.

Also good luck in finding a planet you can terraform in the galactic bulge.

Why the galactic bulge, most likely people look in the mid to outskirts of the galaxy same area that our solar inhabits not where the Galactic black hole is, duh.

Take our own solar system and imagine it without earth. Not one planet would be suitable to be a 1:1 copy of earth.

True, but there's enough material to grow a planet starting from protoplanets, planetesimals, mars or moons, with asteroids and nucleosynthesis.

The galactic bulge contains the most exotic objects. Objects that can be useful for future technology.

It is far more easy to construct a ringworld and create a predictable, comtrolled environment than smashing planets together and look what happenes.

How is mining matter from one object to another uncontrolled? Where did I say smashing planets together, you just assumed that.

You will have to travel about 25,000 +- 5,000 light years just to get that exotic object you want when we can engineer it at home. Everybody you know would likely be dead, and that Ring world and dyson sphere might be broken on your return.

fission of plutonium is more dangerous than fusion of deuterium so that won't be likely.

not nuclear reaction... i had meant this... ( Advanced Stirling radioisotope generator - Wikipedia, the free encyclopedia ).

The prototype generator was to have these specifications:[2]

• ≥14 year lifetime
• Nominal power : 140 We
• Mass ~ 20 kg
• System efficiency: ~ 30%
• 2 General Purpose Heat Source (“Pu238 Bricks”) modules
• Uses 0.8 kg plutonium-238

nduced Gamma Emission, spaceship propulsion would likely be ion drives powered by a nuclear fission/fusion reactor.

if you mean electric engines, there is the vasimr... but how do you connect gamma emission in all this??

Aggravating the rest of the world is a perfectly good reason not to.

lot of the world would support capitalism ignoring the miseries it brings to their own lives... they must be therefore guided by enlightened people... same case with temperature unit.

Also you know what happenes when you lived one year on your terraformed mars and i come from earth or my ringworld and start a fight with you? I can grab you by the neck and throw you 40 meters wide.

1. long before a ring-world is constructed, methods will be found to counter biological effects of low gravity.

2. you come from a higher gravity world... how do you plan to easily fight someone who knows to move in low gravity.

3. how will you come into a world easily ready to make violence and expecting no security measures in return.

NASA has a video showing how it works.

Still, deuterium is more abundant than plutonium.

if you mean electric engines, there is the vasimr... but how do you connect gamma emission in all this??

Vasimr is what i meant. IGE could be used to start a fusion reaction of deuterium to make a pure fusion bomb which would be similar to a supernova nucleosysnthesis to make heavy elements, or to ignite a gas giant to make an artificial star.

1. the only practical solution would be exe skelettons. We can wear armor style suits with internal servo motors. So when we move on a low gravity world the suit can make our movements harder so we stay trained.

2. Astronauts say we adapt very quick to a low gravity environment. Alexander Gerst who was on ISS this year said, that he needed only 10 Minutes to get the basics. The only point i give you is that i would propably react "overpowered" and would need some time to calculate my own moves. I know this effect from my training. When i do some sets with heavy weights and switch to lighter ones it can happen that i lift with too much force, fast and miss the tact.

3. Let me turn your point 1. against you here. If you live on a terraformed low gravity world and i´m from a civilisation capable to build ringworlds...do you think you would have anything that could safe your civilisation then? I doubt it.

Beside that i believe no matter how advanced we are. Fights will always exist. They are part of our nature.
