Measurements of the gravitational constant G conducted at the world’s leading laboratories contradict one another and diverge in an unexplained manner. Klein, N. previously pointed out that these discrepancies can be explained by the critical acceleration of MOND [28—31]. We solved the inverse problem: based on the known experimental "Big G" discrepancies, we calculated the magnitude of the hidden acceleration. The hidden acceleration coincided in order of magnitude with the critical acceleration of MOND, which is driven by the gravity of the entire universe. This fact refutes the seemingly chaotic spread of G values and calls into question the very possibility of using Newton’s local equation without accounting for the gravity of the entire universe. Is this an intriguing coincidence, or a direct consequence of the fact that all research groups calculated "Big G" from the local gravity equation without accounting for the acceleration caused by the gravity of the universe? Discrepancies were not caused by instrument errors, but by the omnipresent gravity of the universe, which was not accounted for in the calculations. Paradoxically, it was precisely the discrepancies that became the most valuable result of all the G measurements. In their pursuit of "Big G," the experimenters missed a scientific discovery. A new law of nature was right within their grasp, yet they mistook it for equipment malfunction. Dear metrologists! Hidden within your vast archives lies the most monumental discovery in the field of gravity since Newton! Don’t let it slip away! Remember: the number of fundamental laws of nature is limited—there aren’t enough to go around!
