Now it is seen as possibly responsible for a basic fact about the Solar System:

John Savard Doesn't have the same ring as "Planet X" but if this thing is 3-10x as far as Pluhe to, it's impressive the Sun holds it in orbit. |

Gravitons are massless, so gravity does not follow the Yukawa potential law; it is a long-range force, following the inverse square law without an exponential factor. Why, then, would it be remarkable that the Sun keeps a body in orbit at a great distance... unless that distance is _so_ great that other stars significantly perturb its orbit? John Savard |

John Savard Doesn't have the same ring as "Planet X" but if this thing is 3-10x as far as Pluhe to, it's impressive the Sun holds it in orbit. Why? That just puts it in the scattered disc, along with millions of smaller bodies. Even a thousand times farther out we have billions of Oort Cloud bodies orbiting the Sun (more than a light year away). There's no limit on how far away an orbiting body can be from the Sun. It just comes down to the distance at which some other body will perturb it from orbit. Far more interesting, I think, is the suggestion that this hypothesized body is a captured rogue planet. Capturing an outside body requires at least a three-body interaction, so if true, it must have come much deeper into the Solar System than its current position. |

(Maybe doing that to Saturn instead would have sufficed.) However, the chances of finding the ruins of a lost civilization on Planet Nine, from which we can learn the secret of building faster-than-light spaceships, remain remote. Which means that it is unlikely to provide me with a way to get far enough away from Donald Trump, should he be elected President. John Savard |

John Savard Which brings up the subject of the aliens asking to be "taken to your leader." They left almost immediately with tears of laughter running down their cheeks! Apparently he claimed to be a direct descendant of Louis the 14th. Sadly the aliens were not taken in by his lavish furnishings. What spoilt it for them was the "Let Them Eat Cake" inscribed in huge, solid gold lettering above the entrance. And "Arbeit macht frei" in black, wrought iron above the immigrant, servant's entrance. |

John Savard Panic? Was that a question? Relevance? FTL aliens would, by definition, be far too advanced and technically sophisticated to fear anything we [shrieking apes] could possibly manage. |

Every time some conservative is running, the libby-progs say "I'm going to run away! Waaaaaa!" Like Alec (Psycho) Baldwin. Guess what? They never do... |

Or, in another reality, the visage of an old, lazy, stupid bag who sold-out (along with her philandering husband) the entire U.S. to China and whomever else would pay them. |
