    The estimated lifespan of the outer solar system has been downgraded from 100 billion years to just a few billion years, according to a study that probed “terminal instability” during the Sun’s death.

      FTA:

      “Newton’s envisioned instability is real after all,” the team. “He was mistaken only about the perpetrator.”

      The news isn’t that the solar system will eventually collapse (the concept of entropy isn’t new) but that the mass loss is not predictable and smooth and the impact of the irregular mass loss fucks with their orbit:

      The recently measured white dwarf recoil demands asymmetric mass loss that is most readily attributed to discrete, independently directed ejections that impulsively perturb stellar motion.

      People are acting like it’s not a problem, but if we have just one more downgrade of that magnitude, we’ll be in big trouble
