Yes. The range of gravity is infinite

Yea, but they would have to be very very dense objects, the gravitational field of a tennis ball, for example, would have almost no strength to affect anything a lightyear away

Yes. It might take longer than the current age of the universe but it would happen.

>>16457327
"almost no strength" is still a non-zero amount.

Conventionally, yes. Under both newtons theory and Einstein's theory, the effects of gravity has an infinite range. The problem is, quantum mechanics says that space and time cannot be infinitely subdivided.
Under general relativity, gravity is the "curvature" of spacetime, which is to say relativistic effects (length contraction/time dilation) caused by the presence of energy density.
So if a gravitating body is far enough away, or small enough, eventually those contractions of space/dilations of time should become so small as to drop below the minimum scale of the universe, eventually time would have to be dilated by less than a planck second/space would have to contract by less than the planck length. Theoretically, this should mean the gravity at that point actually does become null.

Clean it up jannies. OP is a philosopher.

If you believe in science I must presume you've measured

no it doesn't.

yeah they should.
