In the Name of Allah, Most Merciful and Compassionate
Remember: The purpose Quran is not to teach you about Science. It is the book to teach you, what is the purpose your life. Quran is not a book of Science or History. It is a book of signs of Allah. This book was revealed in 7th century to our final prophet Muhammad(pbuh). It is the scripture of guidance for the mankind from 7th century to the end of the world. So if it include scientific things, then it must be in simple language in order to convey it message to ancient people to modern. The Quran contains many scientific facts when it talks about signs of Allah. You can't see very detailed science in Quran, Because if it says everything in detailed, then the ancient people may think the Quran is contradicting with their understandings.
Allah is all knowing and all-intelligent, he knows the most efficient thing to do is to have the Quran accept 7th century belief without contradicting reality. The Quran must support modern belief as well as 7th century belief. And neither side should contradict each other. This tells you that the author of the Quran is very knowledgeable about 7th century belief and modern belief and very intelligent. The Quran avoids certain words so it doesn't negatively affect 7th century belief and modern belief. It was written for all times and places. That is why the Quran seems to hint at things and never explicitly describe them.
