@davidasinclair Best of luck, @davidasinclair ! Exciting times!

After 25 years of brave & brilliant work by hundreds of scientists in my lab to understand then safely reverse aging for the first time, it was moving to witness the first human dose being delivered 🥹 nature.com/articles/d4158…

@infantrydort Another thought just occurred to me: These people came into Europe and acted Medieval; they forgot what Medieval Europeans were like. Now, they may find out.

The most dangerous force on Earth is Western civilization when it remembers that cathedrals and cannons were built by the same people.

@elonmusk @TheAliceSmith They are worried that the populace will decide to take it out of the hides of those who perpetrated this abomination.

@TheAliceSmith Fuck ‘em

They call for calm in the face of horror. This is inhuman and manipulative. The proportionate and natural response to an horrific incident is disgust, fear and anger. They want to downplay the horror to dodge their own political responsibility for it.

As I told the numbnuts earlier today, for all the talk about the Chinese, historically, Europe is the proximate source of all the really major wars we've had to deal with. Anyone with a halfway decent knowledge of history worries way more about what's happening in France, Germany, and Moscow than Tehran, Saudi Arabia or Beijing.

@deaflibertarian It's only my second block, but there's a certain level of obnoxious retard where I'm no longer interested in second chances. He hit it.

@theDonGreer Never!

hit her with the banjo fanger

Yeah, like I said, similar to Arecibo, you could have a medium-sized building suspended from anchors around the rim of a crater (adjustable by moving the cables at the anchor points). Considering it would be 1/6 the weight, you could have all kinds of useful bits in there. But don't worry too much about cooling; just simple reflective insulation, similar to what was on the Lunar Lander, will do just fine-very thin foil, maybe a couple of layers. Have a cradle in the middle of the crater that the thing can be lowered down to for repairs and upgrades with an access panel. If everything is modular, and you set up an array of mirrors to distribute the image, you could have maybe a dozen or more instruments in there at any given time. With regular trips back and forth to the moon (which will be necessary for a base), concept to implementation for a new instrument would be less than a year and maybe a few million dollars. Like I said above, once you prove out the first one, you put in 4 or 5 more at different latitudes and scattered around the moon, and you could basically have a full spherical observation with absolutely ridiculous sensitivity and resolution, probably several orders of magnitude better than anything we have now. Add to each one of these a radio telescope in a nearby crater, and the amount of observational astronomy we could do would go up exponentially. A couple orders of magnitude in magnitude and resolution on the visual wavelengths, and we could do some Arecibo-style radio antennae for radio, combined with fast networking for interferometry, and you basically can do observations with a hard-vacuum telescope ~ the diameter of the moon. It will make Hubble images look like kindergarten finger paints, and a HELL of a lot easier than trying to build several satellites of similar size to fly in formation at a Lagrange point to get a similar effect, and also a LOT easier to maintain. Not that I've thought about this much. :)

@theDonGreer @davidpattersonx Wonder how the lens would hold up in that environment. Might want to have a building to protect and cool it during lunar day

The next space telescope will be 100X larger than the James Webb Space Telescope (JWST). Starship will enable multiple daily flights. We will be able to build things of monumental scale in the weightlessness of orbit. We need to start thinking big about space.

@james_ptweets1 @davidpattersonx Not a problem.

@theDonGreer @davidpattersonx Cool sorry then. People are nuts

@BowTiedMara That's gonna be a very interesting negotiation with the Brits.

Dutch water management will make Argentina Great Again

@james_ptweets1 @davidpattersonx I'm aware... I taught Astronomy labs in college. That's not the dumbest thing they believe. I've been accused of taping a photo of Jupiter or Saturn on the front of the telescope.

@theDonGreer @davidpattersonx Ok fair enough. Some people really think there is a dark side

@deaflibertarian Just block the bastard.

@DoinksTheFrog 💀

@james_ptweets1 @davidpattersonx I didn't say there was. Reread what I wrote. I distinctly said: robots cleaning the mirrors when it's in the light, and observation when it's in the dark.

@theDonGreer @davidpattersonx There is no permanently dark side of the moon

@rustyrockets Maybe they should have paid attention to all the St. George Crosses over the last year. Might have avoided what's coming, and I'm pretty sure ... it's coming. The interesting thing is, this time, the Catholics and many of the Protestants will be standing shoulder to shoulder.

Things are escalating.

@Spider_Mike12 Stop obsessing about my ass, Mike.

@LuckyMcGee @ph409hhh: Soooo, what would be "extreme" in comparison to an attempt to publicly behead an innocent man?

If I am ever beheaded or otherwise killed by some 3rd world sub-human scum, PLEASE exploit and politicize my death for far right purposes, and avenge me accordingly, with extreme and righteous prejudice. Thank you in advance.

@atensnut We got plenty of Rangers. "One Riot, one Ranger."

I hope Texas is preparing for riots and looting tonight. It may even extend to other states.

@US_OGA White-collar jobs aren't going away either. They just aren't the same jobs as we had yesterday.

So let's get this straight -- Fears about A.I. eliminating cubicle jobs leads to protests fighting Big Tech over building data centers ... BUT... Big Tech building data centers and keeping them powered and running is leading an unprecedented Blue Collar jobs boom.... So Blue Collar jobs are eliminating White Collar jobs.... What goes around comes around.....

Well, I was thinking about building the bulk of it in situ; there should be plenty of material to build mirrors, and there's lots of aluminium in the regolith. For cleaning, small robots crawling the primary mirrors when it's on the sun-side could do a good job using electrostatics. After the initial cleaning (after construction), as long as you don't have things like rockets operating anywhere nearby, dust shouldn't be much of a problem. The whole thing could be built in a crater, with the objective suspended (Arecibo-style), and would give you the ability to adjust the focal vector by +/- 20-30 degrees, giving you a really good swath of the sky for observation. Build several of them at different latitudes, and you could get full coverage of the sky with observation times in the days, and a resolution that would be hard to imagine: again, surface features on planets 10s of light-years distant using two or more such telescopes and interferometry techniques. Beats the hell out of trying to pack the thing up into a rocket and unfold it out in the deep, dark nothing.

@theDonGreer Moon dust gets into everything. Transfer to the moon and landing is complicated and expensive.

@ThomasSowell This is something that 90% or more of people get wrong, and even when you explain it, they just don't get it. And it has nothing to do with IQ or Education; I've had this discussion with people with advanced degrees, and they simply don't understand how this works. Amazing!
