you’ve been to the circus, and now are drifting off to sleep with images of a clown juggling, and gravity fades to zero in the dream.
what happens?

newtons first law comes into play.

Is the juggler on the surface of the Earth?
If so, the Earth would explode because of the enormous strain energy which suddenly had nothing resisting it.
This would make juggling difficult.

It’s a dream. Anything could happen.
One possibility is that the juggling balls get attacked by a giant brown and black people-eating monster, who appears out of nowhere. It subsequently chokes on the balls and dies, disappearing into (or converted into?) an instant, localised cloud of fog. I swim away, frog-like in the gravity-free air-fluid using adapted breaststroke. The fog dissipates and a beautiful iridescent blue, green and red bird, somewhat like Carey’s bird of paradise fly/swims along with me. I wonder whether it’s carrying seed for a Kennecott Rock Drill plant.
JERK! Now I’m wide awake.

it’s true, you can juggle quite normally (as if normal gravity) in a dream, and many other things, as you’ve vividly shown.
the obvious answer of course is that whatever being juggled doesn’t return, away it goes.
where I was going with the idea, or what I was pointing to, is that imagination can work in defiance of gravity, as the electrical activity in the bulb on the shoulders does, well, it works independent of gravity somewhat.
when i’m asleep I experience something resembling weightlessness, or zero gravity, it’s one of the joys of sleeping.
in a way, sleeping and dreaming are more like that electrical being independent of gravity.

I wonder if you could throw a micro satellite into an orbit on a really smallish body in space, asteroid, small moon
I remember the experience of levitating while asleep when ~15yo. Dreaming so. Happened a few times, never anything worrying about it as recall.
I gather this is some product of the body being anesthetized in a way, muscles sort of immobilized maybe.
Moving on…
As an analogy, or metaphor, juggling in zero gravity, this is kind of what brain activity is, or does. Detachment from immediate realities of the body-vehicle functioning within a gravitational field (the physical constraints). All life here on earth presumably evolved within a gravitational field. It could be argued it couldn’t have evolved without gravity.
If I take some intuitive math humans do, like the geometry involved in catching a ball, this requires some computation to anticipate the arc
of a ball. That typical physics experienced. Forces.
What i’d like to know is what is the scope of the information involves in rendering the anticipated trajectory, or course of the ball to be caught.
Has me thinking about simulators for missile guidance systems, like there in adelaide (salisbury) when the woomera rocket range was operational. How humans do things like catch a ball helped I bet.
Gravity’s a very useful reference for navigation/guidance.
Something tells me computation (in a broader sense) both requires it (gravity), and detachment from it. The question of the earliest proto-computation in the universe comes to mind, its contribution to biogenesis, and evolution.
I guess you could extract from that above, that AI may have to have experienced gravity, be able to do math from geometry, then do computation outside the physical constraints, to be conscious.
It’s not juggling but in the tv series The Expanse they had a bird (might have been a humming bird) fly and then stop and gently float down and then fly again, was quite cool and attention to detail, I think it was on the asteroid Ceres

Yes, but the question asked is what happens as the gravity gradually fades to zero.
Let’s exclude the exploding Earth scenario.
Several things could happen.
1. If the juggler is outside and keeps his throwing force constant then the balls get higher and higher until they get blown so far away by the wind that the juggler can no longer catch them.
2. If the juggler reduces his throwing force in proportion to gravity then the balls follow the same paths but get slower and slower with each throw. This means that if he wants to he can keep more balls in the air.
3. If the juggler is inside and keeps his throwing force constant then the balls start rebounding off the surfaces of the room leading perhaps to a much more spectacular display of juggling.
Back to the exploding Earth scenario. How much would gravity have to decrease for the Earth to explode?

Yes. Escape velocity for 67P/Churyumov–Gerasimenko is 1 meter per second. The Rosetta spacecraft orbited this comet for a while before landing on it. Orbital velocity must have been less than 1m/s so if you were standing on the comet presumably you could throw an object in to orbit.
