Hi, I'm new here. I want post a specific question thats been rattling around in my head.(adsbygoogle = window.adsbygoogle || []).push({});

Basically, if you consider the curvature of 3 dimensional space into a 4'th dimension due to gravitational field, has anyone considered the 'direction' of that curvature ?

If you think about the curvature of a one dimensional bowstring, by an archers hand or the familiar bowling ball on a trampoline analogy, there is a distinct direction and physical reason for the direction in the curvature that occurs.

By analogy, it seems clear that there must be a 'direction' in which gravity bends 3-dimenional space. It also seems to me that it is always the 'same' direction - otherwise the curvature in space due to the moon could cancel out that generated by the earth. So would that be a universal phenomenon? Could that be demonstrated in some way ?

So what is the 'direction' - is it forward and backward in time ? Or some other spatial 'direction' - but how would the universe know which way to curve ?

Appreciate if someone can shine some light in this area,

Martin
