You are weaseling.
Can you build a reactionless rocket drive
by having a tennis court inside your rocket's cabin?

Yes? No?

Why does a loosely strung racket return the ball faster
than a solid surface racket?
You're 0 for 2, JJ.

One more chance. Build a road in a triangle design; a large
closed loop. Drive once around it, and naturally end up
facing the same direction as the start.

That's one revolution: 360*. And you have traversed all 3 angles
of the triangle. Evidently, this universe's geometry is non-Euclidean.

Can you model this peculiarity with general relativity? What does
it tell us about spacetime on the earth's surface?

Stop weaseling.
Can you propel a rocket by playing tennis inside
with loosely strung rackets?
(thereby violating Newton's third law and momentum conservation?

Again: Yes? No?

You're flailing. 0 for 3, JJ.
Try this:

I) Alice and Bob face each other, a mile apart. They approach, each
walking at 2 mph. A bee starts at Alice's shirt, flying between them,
back and forth, at 4 mph. What total distance does the bee fly?

II) After their collision, they separate, each walking backward, at 2 mph,
to their starting points. The bee again flies 4 mph, back and forth.
Does he finish at Alice, Bob, or the middle?

This shows that nature behaves in a way that isn't time symmetric.
