This is again, another thing that i have been learning in class. It is the first topic in my geosains lectures. This is about how the universe is expanding (the teory of the expanding universe) and about orbits.
Long ago, people thought that everything else in the system is orbitting the earth. but now they do know that all other planets including the earth is orbitting the sun. And also that the sun itself is moving. They also have two teories about the future, that is whether the universe is coming closer to each other or whether it is expanding, and the most acceptable teory now is the expanding universe. That of what has been stated in the quran.
