You heard it on Space-Talk first!
Time is the cause of gravity
Even if logically you think you know better, you/we tend to think that we exist in 3 dimensions. We tend to look at our volume and treat time as something 'extra'. The truth though, is that we exist in 4 dimensions.
'Ah' you say but time moves forward and we exist in time at only one 'present'. I would say to you that you exist in only one place and, like it or not that place is not absolute either!
I will keep the reasoning limited and simple in the hope that someone will challenge me [using a logical argument].
The way in which gravity shapes space and space defines gravity is usually expressed using an analogy of a flat rubber sheet to represent space. Gravity is then illustrated by imagining a [heavy] ball bearing being placed on the sheet. This produces a 'dip'.
This illustrates the shaping of space to give a gravitational dip as a result of some mass acting in space. Smaller ball bearings rolled onto the sheet would then 'orbit' around in the 'dip' like a planet, say.
I want you to keep this analogy in your head and ask yourself where this analogy is often pointed out to lack credence. It is this: the analogy relies on gravity for the ball to orbit. That is the dip is illustrated as gravity but the model needs gravity acting on it from the outside for it to work. An analogy is ok but only useful within limits. I want to remove the above analogy's limitation to illustrate my point.
The issue is what causes the ball bearing (the little one(s)) to roll inwards - that is 'orbit'. My answer is that Time is the cause. As you know it (time) runs slower as gravity increases - the steeper the slope on a 'dip'. Well simply reverse cause and effect. Instead of the dip causing time to slow think 'Objects wish to move through time at the slowest possible pace - a sort of TIME INERTIA.
Obviously this would require the greatest gravitation to have the slowest time er, the slowest time to have the greatest gravitation/time inertia. The analogy, in this way, is repaired. As the analogy does not illustrate time on the rubber sheet it stands up ok.
