i just solved gravity

I initially questioned whether visible matter might repel gravitationally, but refined that to a model where visible matter is gravitationally neutral, contributing no attractive force. To preserve the observed gravitational behavior of galaxies and clusters, dark matter must then interact more strongly than previously assumed. The gravitational constant is allowed to evolve over time or scale. The observed “missing mass” may actually be a misattribution; gravity isn’t missing, but the source is misunderstood.
