I have never met a single person who actually thought 'earth like' meant that we could pack up the kids hop in a spaceship, and just move there. 'Earth like' just means, not completely hostile in every way imaginable.

Mikey1969: nmrsnr: Okay, I have a background in astronomy, so my sense of what the common perception of things is is skewed, but did people actually think that "potentially habitable planet" mean a place you would visit on vacation? All of the accounts I've read have made a point of saying that they are 2-5 times the mass of Earth, and while we have no idea what kind of atmosphere it would have, would very likely not be compatible with us, because we evolved very specifically for our atmosphere.

Exactly, I never thought "potentially habitable" meant Earth 2, Electric Boogaloo, just that it was in the Goldilocks Zone and met a few other basic criteria. I'm thinking someone was just trying to generate interest in an article.


I know nothing about astronomy beyond what's in Star Trek, but based on the articles I've seen, my understanding of "earth-like" was bigger than earth, but sort of in the right place, and they can't tell anything else because they're too far away, but mostly they're happy to find lots of planets. Sounds like I got the gist of it.

Haliburton Cummings: Makh: Well, we found one so far.  So we know it's possible.

the whole thing?


Yep, it's really close.

That's pretty much it, and it's how I've interpreted the articles regarding it. I don't think anyone has been misrepresenting the data, really. Of course, if you get your science news from Cracked, there may be some issues... ;-)

Actually QA usually sticks around to make other points about whether or not atoms age and all that kind of shiat, but I don't think he liked that his whole "Are we not living longer" argument had a great big gaping whole poked in it.

I was referring to digitalcoffee. But yea quantum apostrophe is always filling these threads with garbage. I haven't read one of his tired posts in a long time though :)

Yea, verily.

Can't believe I'm the first to say it.

No. A good chunk of us ignoramuses knew it did not mean ready for colonization.

I actually consider this to be The Most Frustrating Time. Because we've learned that we aren't the center of everything. The sky isn't a ceiling with holes in it, etc.

We KNOW what's out there. We can see it, we can see things that existed before our sun even did. We can see planets around other friggin stars, and make a pretty good guess as to what they're composed of.

And we can't get there to investigate. We more than likely never will be able to investigate them, at our current rate of self destruction, not to mention the people that actually control the money to advance that technology would rather we go back howdy doody days.

DigitalCoffee: Ok, here's the Ten Million Dollar Question:

Let's assume the following:

- an Earth like planet IS discovered
- it IS in the HABITABLE ZONE
- it HAS Liquid Water
- it HAS Human Breathable Atmosphere
- Surface gravity is +/- 10% of Earth
- it HAS rudimentary plant/animal life
- it is 15 Light Years Away

Question:

So What? This isn't Star Trek. You aren't just going to 'pop by' and check out the neighbors. You couldn't even get a science probe there in a human lifetime let alone any sort of expedition. So what would be the practical use of any such find?

/N = RfpneflfifcL


Two words: Generation. Ship. It's really not that hard of a concept.

"Solar System" refers to the planetary system around Sol, in Sector 001 of the Alpha Quadrant, which includes Terra. Other planetary systems would be named for their stars, such as "the Vega System" or "The Tau Ceti System". When not referring to a particular planetary system, "planetary system" would be how you would describe it.

You could send a science probe there in 150-500 years transit time with ~1970s technology. Sure it would be expensive as hell and definitely contravene local arms limitation treaties, but it's not as unreachable as you imagine.


More then that in the last few years we have gone from warp drive is impossible, to warp drive is theoretically possible, but would require more energy then we have in the universe, to warp drive is theoretically possible and only require the energy of a small star, to warp drive is theoretically possible and only would require the energy of a large nuclear or fusion reactor.

So yeah the distance sucks balls now, but given a destination, a theoretically possible way to get there or at least send a probe in less then 100 years engineers might just find a way.

fusillade762: Farker Soze: fusillade762: Quantum Apostrophe: 3D printer

Did a 3D printer rape and murder your entire family or what?

It did, and after that it gave him Space AIDS.

Ouch. That's possibly the only spaceborne STD worse that space herpes.


This ain't the '80s anymore when you only had to worry about nebula crabs, space herpes and gonorrhea beta IX. It's a brave new space world out there. QA knows, he's looked into the abyss and it looked back at him. Then it felt him up with a 3D printed dildo shaped like a rocket ship.

SpikeStrip: 300B galaxies and this is the only planet that supports life. what more proof of god do you need?

Because we checked them all and sure enough, ours was the only one.

Dingleberry Dickwad: You can argue semantics all day. How many people are alive today that would have died a century ago?

How many people live in space? A few test pilots who float around in a tree fort for adults in the upper atmosphere?

What is the barrier to living longer? Is it that atoms have an age? Nope. Are magical materials necessary? No. Impossible energy sources? Nuh uh. Fantasy negative energy matter? Nope.

No magical technology is required, just good old progress in the medical field, same as has been happening before. We will understand aging and it will be reversed.

You know what for sure will not happen? Colonizing space. Deal with it. You're going to have to; living decades longer while still not going into space is going to suck for you. Might as well get over it now.

I'm not arguing semantics. I'm arguing that we haven't increased the natural human lifespan. We've made it to where more people are reaching that full lifespan, but we haven't increased it. You can argue till your blue in the face, but in your heart you know I'm right and you're wrong, and you're going to likely die sometime in the next 40-50 years I'm guessing. Just like the rest of us.

Smackledorfer: Digitalthreadshiat never showed back up? Surprise surprise.


Actually I've been checking in a few times over the past day. Quite a few good responses from everyone supporting why this would still be a Good Thing even if not immediately actionable. Only a few worthless responses, namely your own bellyaching and biatching, which added nothing of value to any of the conversations at hand.

Mister Peejay: Charles_Nelson_Reilly: moralpanic: Ya, i've always been skeptical about those claims. We have 3 planets within the 'Goldilock' zone, Venus, Earth and Mars, and only Earth is habitable. And the best chance of finding life in our system aside from Earth isn't even a planet, it's a moon, Europa.

2061 ftw

You mean 2010, right?


I meant "2061: Odyssey Three," by Arthur C. Clarke. It's excellent. I haven't read "3001: The Final Odyssey" yet.

Regarding 2001 and 2010, the truism is true here too: the books are even better than the movies.
