Grizzly A Mormont Posted July 30, 2016 Share Posted July 30, 2016 We, as Earthlings, have our own unique understanding of seasons. Our planet takes 365.25 axial revolutions to orbit its central star just once. Our annual seasons are due to Earth having a tilted axis. For us, one single year marks one trip around the sun. The concept of a winter lasting 2-5 years, like foretold in the Game of Thrones, is a mind fuck for me. Dragons and White Walkers are nothing compared to a 5 year winter. They must measure their years on something other than a single revolution around the sun. Maybe they count that days based on their moon(s) or some other factor. What would cause some winters and summers to be longer or shorter than those of the past. An irrelgular elliptical orbit around its sun(s)? Climate change? Maybe there is a volcanic range in their world, that when active, Westoros has longer summers and when inactive has winters? Or does it have more to do with Majik?

StoneColdJorahMormont Posted July 30, 2016 Share Posted July 30, 2016 When anything is far fetched or inexplicable on the show the easy answer = Magic or maybe the weight of the gaint folk weigh the planet down... and during winter they eat more and breed Link to comment Share on other sites More sharing options...
Sparksen Posted July 31, 2016 Share Posted July 31, 2016 1 winter in GoT is 5 years and 1 summer is also 5 years (hopefully) so 1 earth year=10 GoT years (7 good and 7 bad years^^ again something religious^^) when it is not magic then the GoT earth is 2,877 × 10^9 km +/- 10^8 away from the sun (position jupiter^^) but the normal temperatur on upiter is -103C° so the sun needs to be very hot/very huge BUT a very huge sun has a way bigger force of attraction and that gravitation grows faster than temperatur. so the Got earth must be way bigger (longer days?) and the sun also^^ so yes it is possible^^ Link to comment Share on other sites More sharing options...

Well i don't read the books and don't know what parts in the show match up with the books, so just said show be it writers or GRRM himself.

Future Null Infinity Posted July 31, 2016 Share Posted July 31, 2016 I think that Planetos is in three stars system (in the stable phase, this thing can't remain stable for very long), the planet will have an irregular orbit depending on the positions of the 3 stars which will affect the lengths of the seasons, here's a simulation Link to comment Share on other sites More sharing options...

That simulation is beyond what I imagined. Thank you for sharing that. Link to comment Share on other sites More sharing options...

They came to the end of longest summer in recent memory. Jon Snow was asked how many winters he has seen. He said 7,8 or 9. I don't remember exactly. But if they were always 5 years long, Jon would have been over 70 years old when he joined The Nights Watch. Link to comment Share on other sites More sharing options...
Sparksen Posted August 1, 2016 Share Posted August 1, 2016 mhh okay (its obviously magic but i like theoritizing^^) but when it is not magic than maybe is the earth losing his orbit around the sun and winter/summer are getting longer and longer^^ or the earth is moving slower around the sun O.o something is slowing earth^^ and one day the earth will stop and they will burn/freeze to death^^ Link to comment Share on other sites More sharing options...
Runaway Penguin Posted August 1, 2016 Share Posted August 1, 2016 Or Planetos has pretty stable and boring orbit with no regular seasons (basically orbit with no tilt) and the winters are combination of sun activity and, say, volcanoes at Asshai souting more or less dust?

Prince of the North Posted August 1, 2016 Share Posted August 1, 2016 ASoIaF seasons could be "explained" by an irregular orbit and/or the planet (Os) irregularly tilting on its axis...or some combination of the two Link to comment Share on other sites More sharing options...
Adam_Up_Bxtch Posted August 2, 2016 Share Posted August 2, 2016 I imagine George just thinking it'd be cool and edgy to have old men telling young kids that they had to wait out a 5 year winter by eating human remains north of a giant ice wall then tell the youngsters how easy they have it Don't think he put much thought into the science side of the years long seasons.

Also we never have anyone in the story mentioning another sun, let alone two. Given how much we hear about the red comet, you'd think someone would mention that. This topic has been discussed a lot. I really think there is not much else than "magic" that we can use to explain it. GRRM certainly hasn't had anyhting scientific in mind when writing it and I don't think something can be constructed ex post. We have a clear reference that the seasons are still linked to the duration of days, so there is an axis tilt, and the progression of the planet through it's orbit is what's driving seasons, not some other celestial bodies or the distance to the sun or something. It's just that the progression on the orbit is highly irregular. If GRRM was a science nerd, the book would have opened with "let's assume that Kepler's second law doesn't hold true in this world" and the book would have been poorer for it...

I tend to think that like most planets, the planet where Westeros is, is not on a tilt, and the seasons experienced in Westeros are entirely magical. I'm not sure what the reality of life / weather planets would be on an earth-like planet with no axial tilt (and thus no seasons) but you could in some way probably call it an "endless summer", at least for regions which get appropriate sun/rainfall. A calendar year, presumably, could still be calculated by Maesters and such based on the positions of other planets and stars relative to the sun, rather than on the dates of the equinox and solstices.

That is, if you are looking for an "occams razor" scenario that is as close as possible to non-fantasy reality. Of course no one could actually prove that planetos isn't the center of that universe, and their sun moves around them at non-regular intervals... I don't want to strawman too much here, but if you think that the celestial mechanics of Westeros are somewhat similar to ours, then "days getting shorter" (which we have textual evidence for) means axial tilt. At least I don't know any other sensible reason for the change of sunlight hours per day.... Now if only someone would take a boat to the southern hemisphere (hemispheros) and see if the north's long night is the south's eternal summer....

So, I guess in my scenario the reason would be the same as to why the weather changes, which is magic. Presumably, in winter it would be dark without the sun actually setting, but you'd think people would take note of that. 2 hours ago, littleRickon said: Now if only someone would take a boat to the southern hemisphere (hemispheros) and see if the north's long night is the south's eternal summer....

I would have to get my books to quote exactly, but I'm quite certain there is a passage that reads "already the days were getting shorter". I think it's good old Ned in AGoT and leads to him realizing once agaon that winter is coming. If he thinks this, and no one has seen a long night in millenia, then it's reasonable to deduce that this is a regular phenomenon with all winters. Thus, axial tilt exists.

SevasTra82 Posted August 9, 2016 Share Posted August 9, 2016 I remember seeing an interview with GRRM where someone asked him about Planetos's axis talk and how it rotates around the sun, etc. I can't recall exactly why he said but he just shook his head and said that he never even put that much thought to it and he was amazed that people actually try to figure out this stuff. He was asked again about the winters and how it works and he just said "hell if I know, magic!!" and did that iconic laugh of his. So my point is...not even GRRM gives a crap about how the universe or the planets work. Link to comment Share on other sites More sharing options...
