Force is a property of the mass, the force has direction, attitude, and carrier, but the force has no speed. Force is coexisting with matters and constantly immortally acing on matters.

Scientists think gravity propagating in space at light speed is a big mistake. Gravity does not propagate, gravity is coexisting with all matters all the time.

LIGO detected gravity waves came from two black holes that emerged 1.3 billion years ago is a total lie. there is no such thing as a black hole, and there are no gravity waves propagating in space, real gravity waves are earthquake produced matter waves.
