On quantum gravity

Experiments have showed that gravity can be manipulated by light. Light – electromagnetic waves – is a pure quantum phenomenon so we can conclude that quantum gravity isn’t just a fantasy. Unfortunately, the search for the right concept to explain the quantum origin of gravity is complicated by the discovery of an observed anomaly in relation to the calculations with the help of Newtonian gravity and General relativity. A mismatch we call Dark matter and it is observable in an indirect way too.
Nearly half a century ago it was thought that gravity was part of the conceptual framework of quantum electrodynamics. Gravity as a quantum field that interacts with the help of hypothetical bosons, named gravitons. But all the efforts in quantum field theory to solve the problem were in vain so the problem became more foundational: “What is gravity?”
