Is Venus humanity's next home?

[jamahir]

I dont believe dyson spheres 're a possibility because the gravitational attraction inside a uniform spherical shell is zero ergo we would need some form of gravity generators to keep the biosphere from drifting. Now how do we develop gravity for such large spheres???
Its definitely not happening in this century!!!

one can spin the sphere like earth does, but i don't see the point of a artificial star unless it is for sunlight... my reasons you will find in my above replies to markus.

by the way, please do look at my post# 22.

thicker bones? The less gravity the more you lose bones.

that was my point... please do read the post again.

It does not matter if you like the idea. People in 1850 did also not like the idea of ocean liners.

ocean liners did not use technology obscenely.

of course they did. Do you have a clue how revolutionary a steam turbine powered, 270m long steel giant with electricity was for people who knew only small, wooden sail ships?

thats why a ringworld is the most practical solution.

Venus is way too inhospitable to be colonized. One freak accident and your whole colony gets melted. Not to mention 24/7 storms and !@#$. In our Solar system, the only planet capable of being colonized is Mars. Just send a bunch of Finnish, Russians, Kazakhs and Eskimos there. Mercury is just dead inhospitable, and Jupiter's gravity would be too intense for human body to handle let alone its dead cold weather.

And Mars might have hosted life in the dead ancient era. A very interesting planet. Let's see if we can find a few fossils, but I have my fingers crossed. There might be more to life than what our pompous scientists with an agenda say. No theory explains how first life formed. Some scientist did recreate DNA within a lab in USA, but that doesn't explain how the first DNA replicated. You see, you need DNA polymerase proteins to replicate DNA. It's highly unlikely that a random DNA polymerase and DNA molecule formed at once at the same place. Although the new thought is that RNA rather than proteins made the first replications, but still, there is no known RNA which replicates the DNA.

Venus seems to much cost for very little in the way of benefit. I mean, Zeppelin ships, needing power, that are able to sustain life and withstand a hostile atmosphere.

I still say Mars is our best bet. It's been visited more, we know a great deal more about the planet and it can be colonised.

 

[MarkusS]

Titan, Europa, Ganymede and Callisto are promising worlds.

The is one world that actually scares me. Jupiters moon europa. We know there is an almost 100km deep ocean under its ice crust. it contains severeal times more water that earths oceans. At the sea floor are volcanos, who heat up the water like on earth at deep sea. It is the most likely place to harbor complex life. It is somehow creepy to think about this.

Terraform Mars.

The problem with that is the giant cockroaches that will inevitably start to attack the humans. The Japanese have predicted such things.

you should explain.

But we all men go to "Venus trap", isn't it??...

it is easier terraforming worlds like mars which already have some gravity and atmosphere.

Terra-forming mars is a good first step, after that we start increasing it's mass through mining whats left of the inner planets, the Gas giants moons, and using fusion of Deuterium to create heavier elements such as thorium and plutonium (artificial super nova) to radioactively heat the planets mantle. The Oort cloud for water.

Also mining the outer gas giants for hydrogen for fuel for Fusion which would most likely the main source of energy by then.

Better get to work on a giant flamethrower.

Sounds legit.

Hmmm..nope.
Ringworld is also a far fetched dream because..
1) It would require extreme engineering and utter mastery of forces of nature.
2) To get earth like gravity it will have to spin 3 million miles per hour, thats very fast.
3) Ring world 'll easily drift off, even a meteor strike can put it off the attractive equilibrium.
4) There would be a perpetual high noon and to counter this shadow squares will have to be placed at about mercury's distance from sun.Again the problem with such shadow squares would be that they will have to be temperature resistant.
5) The ring will have to be super strong and the normal molecular bonds wont be enough.

Oiii?
artificial stars???
I thought we were talking about dyson spheres and ring worlds only.

by the way, please do look at my post# 22.
.

I did.

can anyone tell me why should fahrenheit, kelvin and "degree sign" be continued... why not just use celsius only??
.

Americans 're stubborn!!
Lolzz
Another thing is that with this change (Fahrenheit to Celsius) they would've to change everything and that might cost a big amount like changing miles to kms.Just my guess!

Not gonna happen EVER.

No need for an artificial star when you have advanced LEDs. But if you really want one you can blast a Jovian planet or Brown dwarf at its core with IGEs and cause a nuclear fusion reaction to make it glow like a star or make it explode. Don't know which would happen, kinda risky.

the premise of this animation is unrealistic and over-dramatic... as example, humans going to mars 500 years from now...

what about effects like volcanism and quakes??

The Oort cloud for water.

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

2. the two ice caps on mars are good source of water for decades, i suppose... of course, the settlers must follow a socialist/spiritual/anti-materialistic life to keep the water that long.

3. the jupiter moon, europa, may have enough water... easily accessible, in near vicinity, easily purifiable... through mining the ice on europa's surface and the water that is supposed to be beneath the ice.

Also mining the outer gas giants for hydrogen for fuel for Fusion which would most likely the main source of energy by then.

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.

fusion electricity is unnecessary really... what we should be doing is simplifying.

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.

good points... and i didn't know earth spins that fast... also, ring-world kind of proposals are ideas of video-gamers and professors who want to keep their jobs by assigning students high-technology projects.

Oiii?

I thought we were talking about dyson spheres and ring worlds only.

isn't a "dyson sphere" meant to enclose a star?? and it is markus who keeps talking of artificial stars...

the typical american attitude is unnecessary complication... in politics, spaceships, weaponary, language, computing etc... they should see that a single temperature unit ( like how "byte" is in computing ) will clarify/simplify lot of things... and hopefully disconnect many many useless people from useless jobs and useless companies...

which is why i admire elon musk... he simplifies and therefore makes his spaceships reliable and more capable.

i don't even know how much a mile is to a kilometer.

Not gonna happen EVER.

there is no real reason not to.

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

but you are right... no real need for artificial star when we have advanced led... even spaceship propulsion can use electric engine ( vasimr ) powered by biofuel or solar concentrator.

You got the concept totally wrong. I´m not talking about a "classical" dyson sphere but a "micro dyson sphere. Such a construct would be the size of earth or slightly larger. It is hollow inside. The center contains an artificial "star" which can be powered with antimatter-matter annihilation.

same about ringworlds. Nobody needs a ring that circles an entire star. What is possible in far future would be a planetary ringworld which simply orbits a star. The rotation speed needed would be only 6 circles each day to generate enough centrifugal force to generate 1G when teh ring has a diameter of 10.000 km
