I've often wondered whether dark matter is a by product of the mixing of gravitational fields.
When we look at electromagnetic fields we can observe harmonics and intermodulation effects. This is something of which I have extensive experience in the radio and photonics fields, e.g. beat frequencies, etc.
However, looking at research databases such as google scholar there appears to have been no attempt by physicists to model gravitational field intermodulations.
Has it ever been attempted to model gravitational fields intermodulation in a similar manner to electromagnetic fields thus explain dark matter?
