Where is most "gravity", inside or out?

I would like to see the new deep space telescope , the James Webb deep space telescope peer into this dark hole , for at least a day . Longer the better .

It can't resolve the black hole. JWST is far too small for that.

The image here was taken, in effect, by a telescope with roughly the diameter of the Earth.

Why three clumps of energy , in an almost triangular shape ?

the three nodes are not 1/2 lagrangian points, or trojans circling the BH, but an artifact of the observation yielding different energy levels, according to the comments on the image.

fact remains, that all that gravity induced activity is all outside, not inside the entity.

The discovery of gravitational waves provides a new way for us to understand the universe, however, the speed of gravitational waves does not represent the speed of gravitational fields. The speed of action of gravitational fields is much greater than the speed of gravitational waves. As stated by Newton: Gravity is an action-at-a-distance force. Gravitational waves caused by the revolution of the sun affect the orbits of planets and provide some planetary precession data. The chasing effect of gravitational waves also causes the planetary orbital mechanical energy to continue to increase slowly until the planet escapes from the solar system. Gravitational waves exist; the gravitational model under the influence of gravitational waves that we constructed was a physical model. Through the calculation of planetary orbital precession, the correctness of the gravitational equation under the influence of gravitational waves is verified.

The action "speed" of the gravitational field is instant, because the field, often pictured as a sloping hollow, ( ball on a rubber tarp) is always present as the condition of space around, or outside an object. so
There is more instant gravity outside than inside.

Whether you treat gravity as a force as Newton did, or as a geometric feature of space time as in GR, there is no "instant" gravity.

Well, gravity effectively acts "instantly" on a mass in a static gravitational field.

It's changes to the gravitational field that aren't instant. Those propagate at the speed of light.

To make that clearer; the gravitational field of a body is always there, it does not travel, need to have a measured speed. Example: during an eclipse, the 3 gravitational fields merely merge, whereas the adding/ interruption of the streams of photons takes time to arrive

This doesn't make sense either. Whether you treat gravity as a force as Newton did, or as a geometric feature of space time as in GR, there is no "instant" gravity.

yeah, right! it should be called permanent gravity. and if you look at the rubber sheet: - all the tension, the slope is outside the object.

P.S. well almost. If you could peek into the central ball, there would be tiny slope, nearing the "zero strength" level in it's center., -outside @ infinity
