I've told you this before in other posts, but you like to ignore scientific facts, choosing instead to make them up as you go along. The Sirius system is just in the process of passing by, and has no influence whatsoever on our solar system. Just the facts. It is fine to speculate about things, it makes for a lively discussion, but those pesky actual proven facts always need to be taken onto account, even if they require that 'modifications' be made to your ideas. So what? That's the way interactive discussions work, feedback results in modifications, everyone learns something new. \Paul A

Too bad you can't simulate a damn thing, perhaps because that would make you look even more stupid. Even if there's nothing elliptical and the closing velocity of 7.6 km/ sec were a constant, as for going back 300e6 BP is only an added distance of 7.6e3 ly when that molecular cloud of at least 12.5e6 Ms existed. Is either Sirius and/or our sun the only stars in the universe that are purely random and rogue with no interactions whatsoever? (I don't think so) Stars tend to orbit other stars all the freaking time (of all the silly things, it's called a galaxy, or perhaps at least something binary or trinary). Most galaxies are not known as a cluster of purely randomness, as happenstance populated by purely rogue stars going every which way. What exactly is in our galaxy that isn't orbiting something else? ~ BG
