How can we correlate Buddhist cosmology with astronomical cosmology?

How can we correlate Buddhist cosmology with astronomical cosmology? Basically I have following questions. 1. Moon is considered 51 yojan in height and 50 is the sun. Sun is self illuminated and heat is the outward. Inner is made of diamond. But with modern physics sun is extremely large star fueled by nuclear reactions. Moreover are stars and planets are small elements or are stars like sun as in astronomy? 2. Is Earth flat or sphere? 3. Where can you find the great Mahameru mountain? In science there's an opinion of center of the Galaxy. But it's an opinion and not a theoretical teaching. 4. Can a loka dathu have one moon and sun each or more? Sun and moon is rotating around great Mahameru Mountain. Then how can we correlate that with moon orbiting around earth and Earth orbiting around sun. 5. Is Jambudweepa mentioned is the entire earth or is a part of Earth? Where can we find the other 4 continents. Since there are lots of opinion based answers on internet, I would like if there is a more theoretical answer. Thank you all. May you all attain Nirvana. Theruvan Saranai.
