There's a difference between negativity and living in the real world. ;)Quote:

I can't wait until a habitable planet is found. I just have the sanity to not celebrate the discovery of what is likely a hellish lump of rock as said planet.
Artist's impressions are ridiculous these days. It's like they don't even bother with any facts or reality most of the time.
I think it has to do with either sites like getty and istock and those other graphic design/illustration sites where you just choose the most fitting image.
Or it's because the media outlet wants to excite people about science.
The former is obviously bad for the artists.
The latter is probably a good thing.
I dunno, science should really be about the truth, and giving people entirely false impressions of a discovery just so they'll be excited about it doesn't seem very much in the scientific spirit to me.
That's why I said probably, instead of definitely.
People do need to be more excited about science, but, as you said, I'm not 100% sure if it's worth it, when it's not really actual science.
Asteroids, as a whole, basically have all the same elements as Earth's crust. Did you really not know this?Quote:

None of these projects sound feasible in ANY way; we need the initial resources to BUILD all of these "things" which only serve to go out and find more materials... but then we have to have a way to build the ship parts out of that, we need energy sources for all of these "things", which require more resources... It just seems a bit larger in scale than we can handle at any point even remotely within the next couple centuries (physics permitting) to build a generation ship.
Considering the planet's location to it's parent star I'm willing to bet the chances of it having water in abundance is pretty slim.
It has two stars.
Whats the name of the other star because afaik Kepler 22 is the planets host star. If 22b exist within a binary system that's new news to me.
Why..?Quote:

However, we need to recognize that even if that's possible it's still going to have significant instability to keep water, because we know from previous research that all tidally-locked planets leak a little and there wouldn't be a permanent zone for liquid water.
Also, Kepler 22b’s radius is 2.4X that of Earth and for scale let’s look at Neptune and Uranus, which has a radii 4X that of Earth. If kepler 22b has the same composition as Neptune and Uranus then we would definitely expect it to be on the bottom end of the gas giant and Ice giants, which are the type of compositions that are mostly catalogued for exoplanet discoveries. I'm just sort of leaning to this planet being more on the bottom-end of a Neptunium type planet based off what we know so far.
Project Daedalus estimated in the late 20th century that it would take a minimum of 50-100 years at ~10% of the speed of light to reach the furthest possible star system (15 light years). Not to mention the design for the fusion-powered plasma jet was about 4 times the size of the empire state building.Quote:
