distance increases between two objects when a body decelerates because space time is non euclidean and a body will find the path of least resistance
( but why do objects go on a path of least resistance, why not greatest resistance? Why do they “fall” ? I interpret resistance as being difficult to do , in my human experience like pushing against a heavy object)
maybe least resistance is just our description for the tendency of an object to do something
There comes a point in maths and physics that there is no more ‘why’. The answer is ‘it just is’. Based on our current knowledge, some things are just fundamental rules of the universe, there is no why. We accept the rule and use it in calculations and theories.
Are you talking about a body in orbit? How the orbit gets smaller (decays) as the ‘moon’ decelerates? Basically why does gravity pull things in?
In general the 'least resistance ’ idea usually comes down to the first and second laws of thermodynamics - 1. Energy can never be created or destroyed in a closed system, just transformed and 2. Everything tends towards maximum entropy minimum energy (rocks don’t roll uphill). These are often taken as fundamental and all the why’s come from them. Why? Entropy baby.
Entropy is the messiness of the energy. An imperfect analogy is that if you drop a glass on the floor it will shatter. There is the same amount of mass energy in the floor and glass before and after but it’s distributed and won’t go back together again as easily as it smashed. But I think I took us on a side quest. Sorry!
okay, I got it ( I think. ) my brain hurts

I know, I was taught that. Physics is what, not why, it was like that when I went to uni
it just bothers me, it’s always bothered me
one reason for physics is what I heard discussed was that humans are just not intelligent enough to understand or figure out
and that is quite possible

I’m talking big distances
and if mass/energy is neither created nor destroyed then what is entropy?

it’s only messy in our eyes
also, by falling I mean movement, all movement is falling ie, travelling on a path of least resistance
