The star field behind the black holes is being heavily distorted and appears to rotate and move, due to extreme gravitational lensing, as space-time itself is distorted and dragged around by the rotating black holes.[1]
Newton's law of universal gravitation
states that a particle attracts every other particle in the universe
using a force that is directly proportional to the product of their
masses and inversely proportional to the square of the distance between
them.
Spacetime in general relativity.
In general relativity, it is assumed that spacetime is curved by the presence of matter (energy), this curvature being represented by the Riemann tensor.

In
Einstein's geometric theory of gravity, the situation is described in a
completely different way: A mass that we place in an region of space will lead to a distortion of space-time. Empty spacetime is flat - it looks exactly like the spacetime of special relativity. Spacetime in the presence of masses is curved.

What is the general theory of relativity?
Albert
Einstein's general theory of relativity is one of the towering
achievements of 20th-century physics.
Published in 1916, it explains that what we perceive as the force of gravity in fact arises from the curvature of space and time.
Einstein proposed that objects such as the sun and the Earth change this geometry.

What is Einstein's theory of gravity?
GETTING A GRIP ON GRAVITY Einstein's general theory of relativity explains gravity
as a distortion of space (or more precisely, spacetime) caused by the
presence of matter or energy.
A massive object generates a gravitational field by warping the geometry of the surrounding spacetime.

When was the general theory of relativity published?
Then Albert Einstein shook the foundations of physics with the introduction of his Special Theory of Relativity in 1905, and his General Theory of Relativity in 1915 (Here is an example of a thought experiment in special relativity).
