Quote:Originally posted by jewelstaitefan: Another apparent discrepancy is that Beaumonde is likely located in the Blue Sun system, but has been placed in the Kalidasa System. This placement causes great conflicts in the portrayal of Serenity BDM, and also less so in lines from Our Mrs Reynolds. In Our Mrs Reynolds, Mal says it will take 5 days to get from Triumph to Beaumonde. If Beaumonde is in Kalidasa system (as given in Map or the Verse and White Paper), then even if Red Sun is as far away as possible from Kalidasa, it is only 211Au maximum distance, needing only 94 hours to travel it, which is under 4 days. If Beaumonde is in Blue Sun system, then the max distance between Triumph and Beaumonde is 267Au, needing 117 hours to travel, or about 5 days. In Serenity BDM, the trip from Miranda to Mr Universe's place on the Comm Station is portrayed as not too many hours, and a key is that it's fairly quick between baiting the Reaver Armada and encountering the Alliance Armada. If Mr Universe is 59Au from Miranda, then it would take 30 to 33 hours for Serenity to traverse that distance (with the old engine force circa Firefly episode version, not considering upgrades from Lassiter sale). If Miranda was closer to Mr Universe, such as 47Au, it would take about 25 to 28 hours. At Lightspeed it's still 6 hours. If Mr Universe is any farther than that, the screen portrayal clearly does not match. With Mr Universe located almost across the verse from Kalidasa system (150 degrees, specified in White paper), This means it would take 5 days to travel between Kalidasa and Blue Sun systems. Lilac, Haven, Training House, and Miranda are all in Blue Sun system. If Beaumonde is in Kalidasa, then from Lilac to Maidenhead is 5 days, then another 5 days back to Haven. This does not mesh with what's portrayed on screen, not to mention why Fanty & Mingo are contracting an illegal job on the opposite side of the verse. If Beaumonde is in fact in the Blue Sun system, then all onscreen portrayals of travel and elapsed time are reasonable.

The orbital speed of a body is a fixed quantity, entirely dependent on the apparent mass of the centre of gravity, and the satellites distance from it. It would appear from the other thread that the planets have such long periods that the distance changes are irrelevant on human time scales.

It would appear from the other thread that the planets have such long periods that the distance changes are irrelevant on human time scales. I understand that, that's why the idea of stagnant planets with such long orbital periods so as to be essentially stationary doesn't make sense at ALL to me. Either we're saying they're stagnant relative to each other, or we're saying they're stagnant to a fixed point in space. Either way it's a big WTF to me. I think I prefer a system where the planets orbit at whatever rate their distance would dictate, and years, seasons, and calendar days are determined by a careful axial wobble separate from their orbit. But then again... Some planets are going to be so distant from their sun that solar radiation is about similar to other stars in the sky, so I also wonder how even an axial wobble could create seasons in those cases. But at least for a calendar, that could work.

Quote:Originally posted by Bytemite: I'm looking over it some. I haven't quite gotten to the part in your discussion where you explain the orbits and seasons and axial tilt.
Quote: But I think I understand what you're saying. The planets just have long orbits, even ones close to their sun, according to the white papers. And planets far from their sun have really, REALLY long orbits. Which, I suppose since humanity has invented grav screening, orbital velocity doesn't necessarily have to be consistent with gravity and distance. Hmm. Okay. Hey, so if Shadow is the farthest planet from it's sun, maybe that explains why it's called Shadow. I think I read it's about 18 AU away... That would put it about at Uranus' distance from our sun, and receives an intensity of light about 1/400 of our sun. Going by sky luminance, that means that midday on Shadow would be more like twilight on Earth. Probably something similar goes on with Osirius. From what I recall in the series, the shot we get of the Tam's estate looks like early morning or late evening.

Quote:Originally posted by Bytemite: Hmm. In that case... Murphy's luminosity is 1/50th of the sun. Shadow orbits at about 0.06 AU. L = (M/Msun)^3.9, converted to watts (Lsun = 3.9*10^26 W) and calculated for apparent brightness. b = L/(4*pi*r^2) where r is in meters. After getting the apparent brightness of Murphy from Shadow, I calculated the apparent brightness of the sun from earth to compare the two. Murphy is 6 times as bright from Shadow as the sun is from earth. That's okay, because sky luminosity varies on earth by 10^-2 to 10^3 from dawn/dusk to midday. Midday, though, might not want to be out at midday. Unless Shadow happens to be a stormy place.
