Pluto, unjustly demoted, will have the last laugh.
The dying Sun may tear the outer solar system apart far sooner than anyone expected.
New research in The Astrophysical Journal Letters suggests that once the Sun sheds its outer layers and collapses into a white dwarf, Jupiter, Saturn, Uranus, and Neptune could be thrown into chaos in roughly a billion years—not the nearly eternal stretch of a quintillion years previously imagined. Earth will almost certainly be long gone by then, but the gas giants may not survive either.
Traditional models assumed the outer planets would quietly endure for eons until a random passing star finally disturbed them. Researchers Konstantin Batygin and Jim Fuller of Caltech, along with Fred Adams of the University of Michigan, found a more violent possibility: if the Sun loses mass in discrete bursts rather than a smooth wind, the planetary orbits can be destabilized relatively quickly.
“Everything changes when the envelope departs in pieces,” the authors wrote. In simulations of 672 burst-driven scenarios, up to 96% of the systems became unstable within 3 billion years after the Sun became a white dwarf. About 40% suffered disruption or violent scattering even earlier, before mass loss was finished. Some planets were ejected entirely; in others, Uranus and Neptune swapped places.
Gentler bursts sometimes locked planets into stable resonances that held for billions of years, but the overall picture is clear: the Sun’s death may not be a slow fade. It could be a comparatively rapid, chaotic upheaval that ends the orderly architecture of the outer solar system far sooner than once thought.
As an American, I think it’s weird that the English are so bad at spelling their own language. Adding the unnecessary “u”, flubbing the “er/re” ending. They belong in language gaol.

On a vacation to the Pacific Northwest and overwhelmed by the number of drivers piloting #Cybertrucks, and they're ugly as sin. The trucks that is, not the drivers. I don't think the drivers are ugly. It's hard to tell with the tinted windows.

While I appreciate innovation in the processed frozen potato space, how am I going to be able to tell my Dino Tots from my chicken nugget Dino Buddies when I am enjoying fine dining?
The Oxford comma is doing vital work in this sentence from @PillarCatholic's Starting Seven.
“Given recent events, it is our duty and obligation to recenter and rearticulate the strongest possible moral and theological claims that undergird Notre Dame’s ‘unwavering’ institutional commitment to life.” – dCEC Director Jennifer Newsome Martin in Public Discourse

Hey @belkin: have you heard the outcry yet and made moves to reverse your terrible decision about WeMo Cloud Services? Leaving your customers hanging is no way to thrive as a company.
