He doesn't write for them. They're only hosting his "editorial" to boost how many people see it. The net effect is more people realizing that he is unfit for public office.

I give it two years before he's found out as gay.

No one's keen on having their mind changed, anymore. Anywhere.

To paraphrase my friend (kleinbl00), our culture has shifted towards extreme ego involvement with one's worldview. And if there's any shred of cultural Darwinism at play, the evolution of humanity will absolutely select against that culture. It's an incredibly unscientific and unsustainable mindset.

Eh, but at the same time, my lack of action perpetuates the exact "lack of self-policing" problem that I'm opposed to.

And hey, what's up with the 60k strong anti-Muslim rally in your neck of the woods? Has that been over-sensationalized by U.S. media?

Edit: awh :/

The other day, my ex-employer posted a video to F-book in which female workers threw a bunch of water balloons at their work-attire'd male colleagues, who were lined up against a wall, as some sort of fundraising event, maybe $1 per balloon or so. It was captioned, simply, "Girl Power!". A lady stopped by in the comment section to say how derogatory and berating it was to full-grown women when one refers to them as "girls". I penned up a (hopefully) thoughtful response about why I thought she was doing feminism a disservice in that instance, but I couldn't bring myself to hit enter. Something told me that it would have been pointless to engage her.

I think the current tribalism in America has enabled extremism to rise up on both sides of the political spectrum, because each side no longer polices itself. But as a white male who has lived a life pretty much devoid of any trauma whatsoever, I feel wholly unqualified to make assessments, except in 100% obvious situations (see paragraph #1).

Linking to the previous Michael Lewis piece on the DoE:

I'd love it if he did NASA next. I guess there's not so much a sense of urgency there, though; NASA isn't keeping anyone alive (as directly), although the climate science they're doing arguably does/will.

I'd also love to hear some counter-arguments to the allegations he's laid out. But it has to be (like he says) something more sophisticated than "big government is bad, and the poor all deserve their lot in life because they're just lazy".

...Do you ever feel like you already know enough? :P

That's a great point. Of course our "habitable zone" might not be so habitable to another lifeform born of an entirely different environment than Earth's. And think of how weird things might get when you consider regimes far from standard pressure...

The recent arsenic-based DNA sham comes to mind (edit: not 'cuz it required non-STP conditions), but hopefully we don't use that to reinforce the notion that our exact organic makeup is the only possibility.

    1) How far out into the galaxy do our own signals travel before they dissipate or become no longer recognizable as being "not natural?" How far away are we visible to anyone who is looking? And when are we visible there?

That first one is difficult to answer. It's a matter of resolving a signal awash in noise created from natural planetary, astrophysical, and galactic processes. And extraterrestrials might have come up with some pretty clever ways to do such a thing, but we've still gotta consider the time delay of the signal. Humans have only been making radio waves for ~150 years, so only extraterrestrials within ~75 light years away would have had time to receive them, respond, and send a signal back at us (if they chose to, of course). Anything further away than that, well, we wouldn't know if there's something there yet. And it appears that there are plenty of planetary systems (likely with moons, too!) within 75 light years, but I'll bet that intelligent life is quite a bit more sparse than that.

Now, if you're talking optical detection, and presume that extraterrestrials are looking for man-made structures, I think the pyramids might be our best bet. So that's ~4500 light year radius of signal, only 1/10th of the radius of the Milky Way. And we'd have only just heard back from anything within ~2250 light years. To give you an idea of where we are with optical wavelength resolution, I'd estimate that it could take us another 200 years-ish before we're able to resolve pyramid-size surface features on the planets orbiting Proxima Centauri, and that's only ~5 light years away. And hey, if they'd seen "only" dinosaurs (my quotes/italics, for emphasis), that would have absolutely warranted sending shittons of probes here. Probably a continuous stream of probes. Definitely an argument against aliens, at least in the Milky Way, and intergalactic exploration seems downright impossible. Sucks :(.

    2) Then there's the question of how would you build and launch a spaceship from a world where you live in liquid under a mile of ice?

Shoot, they could figure something out, I have faith in our hypothetical intelligent species!

    3) Would the moons of such a gas giant, if close enough to the planet, benefit enough from the magnetic field to be used instead of building a space station?

Maybe! I just checked, and although Jupiter's four largest moons (Io, Ganymede, Europa, Callisto) all intersect the deadly radiation belts, there are some captured asteroids that supposedly orbit in the sweet spot just above the cloud tops. One of those with a small orbital inclination (so that it doesn't intersect the high latitude portion of the rad. belts) might be perfect. And I'd wager that systems like Jupiter and it's moons are relatively common. We already know that Jupiter-like planets abound, but don't know much about how commons moons are, and the distribution of magnetic field strengths, orientations, stabilities, etc. Of course, the planet has to orbit within a habitable zone... ugh, so many variables.

...but it was a virgin birth...??

Oh sorry, we should let him keep talking.

If by "intelligent life" you mean lifeforms either A) not of sufficient intelligence to broadcast detectable radio/light signals or establish surface-level architecture (at least, within our solar system) or B) of an intelligence so advanced that they use a method more advanced / less traceable than light signals. Maybe they'd use neutrino beams, or maybe they've hacked quantum entanglement. Or perhaps they're just hermits.

Otherwise, I guess the most "intelligence" you could hope to find is something akin to dolphins. Anything of a higher level of intelligence would have deduced that their world is spherical in shape, and we can venture a guess that some of them would've had enough curiosity to start exploring upwards. The most I'm expecting to find in our own backyard is complex organic molecules. Even microorganisms would be a shock.

But for other solar/planetary systems, well, that's where things start to get interesting. Especially with how common extra-solar systems are, apparently (thanks, Kepler mission!).

Oddly enough, I ran into Alan Stern yesterday. He was giving a quick speech at a memorial service for one of the space engineering community's greatest minds that was recently laid to rest. :(

Edit: Ah, right, the other questions:

1. Re: Fermi's Paradox: What incentive would an alien race have to make their presence known to us? Benevolence? Were I an advanced alien, I would let Earth keep incubating without interfering until they'd proven themselves deserving of assimilating into any existing galactic order. Granted, this is all presuming intelligent aliens exist, and I'm not sure that they do.

2. Very likely, but not in our own backyard. Now that I think about it, I'll bet that the challenge of space travel is even more daunting for liquid-dwelling lifeforms, because liquid (in general) isn't as compressible as gas, and compressibility is handy for transporting finite resources during space travel.

3. When we develop the imaging capabilities, we should look for alien space stations in orbit near the cloud tops of large gas giants with large magnetic fields. A strong magnetic field offers protection against solar flares, cosmic rays, and nearby supernova explosions.

Yeah, recon sucks, but I learn some valuable new lessons on every cyber trek. Magnetospheric physics are comparatively boring, and probably a leftist conspiracy anyway
