http://news.nationalgeographic.com/2015/07/072315-kepler-exoplanet-earth-452b-space-science/ (http://news.nationalgeographic.com/2015/07/072315-kepler-exoplanet-earth-452b-space-science/)
So apparently Kepler 452-b is fairly earthlike. 60% larger, 50% older, and 500% 400% more massive, but in its star's habitable zone, and with a 50/50 shot of having a rocky surface. Its atmosphere would be thicker than Earth's, and we have no idea what its made of, but this is the most earthlike planet we've yet found.
-
60% larger... and 500% more massive
...Huh?
-
Straight from the NatGeo article
Kepler 452b is about 60 percent larger than Earth, and perhaps five times as massive.
Then again, I suppose that would only be 400% more massive, wouldn't it.
-
Now I'm not sure if that's actually an error, or "larger" and "more massive" really do mean different things in astronomy.
-
60% larger... and 500% more massive
...Huh?
1.6 times Earth's radius. Volume and mass are proportional to the cube of the radius.
We don't know the mass, though, so we don't know the density of Kepler 452b and we can only speculate whether it's terrestrial (Earth or Venus-like) or a smallish gas giant. It's technically a super-Earth and it's in a habitable orbit, but I'd hold off on calling it Earthlike without more information.

Or it could be 1.6 times Earth's volume, and 5 times Earth's mass. It's very possible if the planet is a lot denser.

Sort of, but not quite. Indeed in this case "60% larger" is talking about its radius (which is a weird way of putting it) but assuming a straightforward mass ∝ radius^3 relationship would imply the planet is 4.3 times* more massive, not five times. This is because planets of different sizes are also likely to have different densities, so while volume is proportional to radius cubed, mass is not exactly proportional to volume.
The "5 times more massive" thing actually has fairly big error bars, but it's the best estimate they have based on probable composition.
*(1.63^3, 1.63 being the best number I could find for the radius relative to Earth's)
-
I wonder if it has life.
-
I hope they're not having an election...

Sounds good. We should send all the feminists and SJWs there.
They have 1.6 times the radius and about 5 times the mass of a normal human so it should suit them perfectly.

Is a (male) feminist. Weighs 120 lbs. Waist is 29 inches. You were saying?

The correct term is "satellite".
You'll never accrete enough mass to be a TRUE feminist.

Ah, self depreciation. The best kind of humor!

Hmm, I'm about 130 pounds. Can I at least aspire to be an SJW? I mean, I have a tumblr and everything!

Can you spin a bullshit victim narrative about it?
-
Sure. Do you prefer: "stop shaming me for not conforming to your stereotype of what an SJW should look like!", "your discriminatory desire to move people you dislike to another planet makes you WORSE THAN HITLER!" or "this entire discussion ignores the American privilege of having access to a space program that has successfully sent people to space!"

How about:
So what if successive administrations have underfunded NASA to the point where it can't carry out manned missions any more, let alone lift a 7 ton "body positive" feminist into orbit. And so what if two thirds of all youngsters enrolling in college are now female, we still need to defund NASA and use the remaining money for more women-only scholarships
It's a perfect way to showcase your ample belly AND your leftist self-awareness at the same time!
-
Fuck you would want to be short to have an 'ample belly' and weigh 130 lbs. In fact you'd need to be about 4 foot. Is the talk of huge fat women turning anyone else on?

i laughed out loud, thank you mr troll, that was really funny.
you forgot one thing though... the "zing!!" at the end.
edit: 178cm for 64kg, male feminist and anarchist to boot. roast me.

*spits guizonde, puts him over fire* Okay, what now?

sing me a lullaby? hey i'm roastin' here. might as well milk it for all it's worth... ;D
-
hush a bye baby in the fire pit
when the wind blows your flesh will season
when the bough breaks the spit will fall
down will go Guizonde
seasonings and all

Ah, seasonings! I knew I was forgetting something. Thanks for the help Niam. *salts and peppers and adds secret rub o' spices to guizonde* So, when he's done, who wants a piece?

is this the part where i say "bite me" unironically?
-
Of course!
-
Of course!
well then.... "bite me" (unironically)
-
Eh, I'm not a cannibal, and you're not quite done yet even if I was. I think I'll hold off, thanks. Also, could you be so polite as to shut up and die already? (This is not serious in any way, and I really hope you don't actually die. Please don't die.)

haven't for the last 8 times, the reaper owes me money, so he's shying off for now. [/gallows humor]

Ah. Well that makes this exercise rather pointless. *un-spits him* Well, carry on, hope you feel roasted enough. Also, how were you talking while impaled on a spit? Just curious, wanted to know for... reasons.

sign language! ;D

Fair enough, I suppose. Waaait...

me? leaning on the fourth wall? naaaaaaaaaaahhh...

I'm sure you'd never! That'd break immersion!

If it means anything, Guizonde, you're a rare person. We were going to cook you accordingly.
-
Could we at least agree on medium-rare? Can't tolerate rare meat, grosses me out.
-

Yeah, I also prefer medium-rare. But I have a friend who won't eat anything more done than blue rare, or, as she put it, "Bring it to the table mooing and slice the meat off here."

That's...I'll put it bluntly, that's disgusting. Meat is cooked for a reason!

I think she still wants it seared, but, y'know, at the table.
-
seeing all the heat my cooking level generated, i should be well done by now!
-
Mmm, safe for consumption.

totally relevant.
i prefer medium rare, myself, fwiw...
-
Medium rare to medium, for me.
-
Medium Well to Well Done for me.
I prefer my meat cut thin, little or no juice to the meat. Much teriyaki sauce.
-
Can I just say that I love how this forum can derail a talk about an Earth Like planet being found to their steak cooking preferences.
-
Steak and, in some places, burgers. I always at least order medium. Anything else, and it'd be damn near raw, by my standards. I like my parasites and diseases dead, thank you.
-

welcome to the forum! ;D

I can live with medium but no more.
-

Burgers I would never have anything less than well done, as much as I like my steak medium-rare. Granted, that only applies when I'm cooking the burgers myself--if I go anywhere to buy a burger, the store won't ask because they'd get sued if a customer contracted something from an undercooked burger.
-
No quicker than medium-rare, for me, but I much prefer medium-well.
-
I'd kill for a big-ass steak, right about now.
-
Anything less or more then medium-rare and you're asking for trouble. Burgers should always be well-done as it's a mix, not a slab of meat.
-
Well if we're gonna go down this path I prefer my steaks medium rare not too cooked not to red. While burgers I generally go well done since intestinal parasites and salmonella are a thing. Also on the topic of the planet I think it's interesting I'm noticing that we are discovering more and more earth like planets which is a strange development to say the least.
-
Not really. We're just getting better and better telescopes.
Ironbite-talk to me when we can feasibly visit them within 5-6 months.
-
But space has recently been doing awesome stuff new planets found, a brown dwarf with borealis and Pluto has a part of it called Cthulhu.

Yes, that was the joke.

I figured the full set was worth mentioning.

Fair enough. I'm a fan of all the ones with similar sounding names.
