Space-time & gravitation

[Girish Kumar Beeharry]

Dear Indologists,

I would like to know whether ideas/theories about space, time & gravitation have been
discussed in the Indian peninsula before Newton's time, say. I am not asking for
mathematical theories but whatever discussions there might have been on the
attraction of bodies (eg apples falling or the motion of the Moon) within a
space-time framework. I am more generally interested in what the Chinese, Tibetan
and civilisations not influenced by the Greek-Roman-'European'* civilisation have to
say on gravitation. Any reference is most welcome.

Many thanks in advance.

Greek-Roman-'European' and start a new mahaabhaarata! :-))
