Coltrane's antigravity

From The Jazz of Physics (2016) by Stephon Alexander, a Brown University physics professor and musician:

John Coltrane passed away in 1967, two years after the cosmic microwave background radiation, a relic of the big bang itself, was discovered by Arno Penzias and Robert Wilson. The discovery crushed the theory of a static universe and confirmed an expanding one, as predicted by Einstein’s theory of gravity. Among Coltrane’s last recorded albums were three entitled Stellar Regions, Interstellar Space, and Cosmic Sound. Coltrane [who was “fascinated by Einstein and his ideas”] played with physics in his music and, incredibly, correctly realized that cosmic expansion is a form of antigravity. In jazz combos, the “gravitational” pull comes from the bass and drums in the rhythm section. The songs in Interstellar Space are a majestic display of Coltrane’s solos expanding, freeing themselves from the gravitational pull of the rhythm section.

John Coltrane, composition and tenor sax. Rashied Ali, drums. “Mars” and the rest of Interstellar Space were recorded 22 February 1967 at Rudy Van Gelder’s studio in Englewood Cliffs, New Jersey. The album was released on Impulse! Records in 1974.
