A new study reports conclusive evidence for the breakdown of standard gravity in the low acceleration limit from a verifiable analysis of the orbital motions of long-period, widely separated, binary stars, usually referred to as wide binaries in astronomy and astrophysics.

1st observational evidence linking black holes to dark energy
Searching through existing data spanning 9 billion years, a team of researchers led by scientists at University of Hawaiʻi at Mānoa has uncovered the first evidence of “cosmological coupling” –a newly predicted phenomenon in Einstein’s theory of gravity, possible only when black holes are placed inside an evolving universe.
Can cosmic inflation be ruled out?
Astrophysicists say that cosmic inflation – a point in the Universe’s infancy when space-time expanded exponentially, and what physicists really refer to when they talk about the ‘Big Bang’ – can in principle be ruled out in an assumption-free way.
