alt Hacker NewsWorlds more habitable than Earth?
Comments
one thing to point out: with a planet that is 20-30% larger than the earth the rocket equation makes it almost it impossible to get out of the atmosphere with chemical rocket technology. So even if you could visit, we could probably only have drop ships or rovers. coming back out of the gravity well without space elevators or stuff would be very hard. It also means that life on those planets would be hard for them to establish a space faring society.
Anyone else feel ripped off? There are solar systems with 6 possible Earth like planets and others with Super Earth Garden Worlds and what do we get? One measly mediocre Earth with our nearest neighbors being a poisonous rock and boiling ball of acid.
If one of these worlds interests humanity enough to have a coordinated attempt to reach there, that itself will be a huge win in terms of the side effect technology benefits that will come out of it.
I suspect that many lush worlds would not have oxygen atmospheres.
Oxygen is really a deadly poison, to many theoretical lifeforms. There's a good chance that an alien landing on Earth would be unable to breathe our air.
Of course, it could be argued that we are well on our way to not being able to breathe Earth's air[0].
I'm not sure how to phrase this question... so here are some thoughts I'm having.
Suppose you find a habitable planet, land there and start colonizing. Would we have to bring our bacteria / viruses with us to survive? Like, the idea that it would not be possible to get the flu again; but is therea trade-off? Would other bacteria eventually mutate sufficently to become infectious, and perhaps, would be even worse.
Our immune system would be tested. Assuming there is bacteria on the habital planet, it's not clear what would happen.
I guess the core of my question is: how homogenous is life?
most worlds without humans that are habitable are more habitable than earth.
its the people that make it unsustainable
More hospitable? You mean like, a planet with no ice on it?
Soooo, we can move other there, swarm like locusts, and destroy THAT planet too?
Is there any plausible way for a human to ever reach one given what we know about physics at the present?
Any anthropic observation requires merely a satisficing condition, which generally means that most requisite conditions are not optimal, including consciousness :)

my brother in Christ I just barely read the title
note that Musk, DOGE et al has completely defunded the Habitable Worlds Observatory Space Telescope
it was slated for 2040 as the successor to Roman Space Telescope
now that will never happen, at least not my lifetime
HWO would be able to directly image worlds the size of earth
(Roman cannot, only massive uninhabitable planets)
ps. just ONE day of the Iran War would have completely funded HWO

We just need to find where The Ancients buried the Stargate on Earth. Let's gooo!
I mean, could be!
But also irrelevant.
Really Earth is only slightly habitable. The atmosphere is thin, there’s not a lot of fresh water. Temperatures fluctuate wildly. There’s probably better planets. Earth is maybe only good for marine creatures.
How about ... fixing this planet first?
Well, being a Continental World I would assume our Habitability is at 80% (although we've employed a lot of Terraforming so perhaps we're higher than that now) - but if we could locate a Gaia World in any Hyperlane-adjacent system, that would certainly be a great 100% Habitability target for any future colony ships.
