It could be a symbol of extreme or unexpected events in the novel. Pigs flying goes against normal reality, so in a science fiction context, it might represent a huge shift in the fictional world's rules or a very strange phenomenon.
It really depends on the fictional setting and the rules established within that particular story. Sometimes, characters can fly through magic or advanced technology.
One possible moral lesson is to be practical. Since pigs can't fly, it tells us not to waste our time on impossible tasks. We should focus on what is achievable in life.
To make 'pigs fly' believable in a science fiction novel, you could create a world with different physical laws. For instance, if the planet in the novel has a much lower gravitational pull compared to Earth, it could be easier for pigs to achieve flight. You could also introduce an alien species that has the power to make things fly, and they use this power on the pigs for some reason. Additionally, you could use a scientific concept like quantum entanglement in a creative way to explain how the pigs are able to fly. By building a detailed and consistent scientific framework within the novel, you can make this seemingly absurd concept more acceptable to the readers.
Well, generally speaking, the main idea might be about the impossibility or absurdity. Pigs are known for not being able to fly in reality, so the story could be using this as a metaphor for something that is clearly not going to happen. Maybe it's about people having unrealistic dreams and finally realizing that some things are just not achievable, like pigs flying.
The pigeons at the music station usually flew together at around seven in the morning. The pigeons on the music station would open the shed in the morning and release them. The pigeon owners would clean up and change the food and water. The pigeons would return to the nest about half an hour to an hour later. In the afternoon, they would fly again in the same way as in the morning. If he released them three times a day, he would release them again at noon. The exact time may be affected by the weather and other factors.
