Sadly, you haven't replied to this....... and I was SO looking forward to explaining the 'one over r squared' rule to you!
Anybody ELSE who has been reading it might like to know that the influence on the 'Local GIANT' of Jupiter is all but UNMEASURABLE on the Earth!
The Moon can raise the sea level (i.e., tides) by up to FIFTY FIVE FEET! Jupiter might raise the sea by 0.1 millimetre!
The point is the WEAKENING of gravity decreases STAGGERINGLY quickly with increasing distance. By the time you get to Jupiter, you'd need somthing MILLIONS of times bigger than Jupiter to affect the sea by as much as the Moon does.
Here's a page that may help you:-

Taking that NEXT step........ not even the utterly MINDBLOWINGLY, HUMUNGOUS, completely UNIMAGINABLE mass of our OWN Galaxy's BLACK HOLE (at the centre of our Galaxy) has a MEASURABLE effect on our tides.
....... and so..... to make the school boy H*O*W*L*E*R of suggesting that a galaxy some TWO BILLION LIGHT YEARS (TWO THOUSAND MILLION times further than light can travel in a whole YEAR) away might have some effect........ might JUST show you how FAR Singers is out of his D*E*P*T*H!
