Is There a Dark Matter in Solar System

There are two illogicality ideas. One, there is a lower density of matter of the universe (than the solar system's) for explaining an observation of the flat structure of the universe. Two, there is an observation of 96% dark matter and dark energy in the universe, but there is not more dark matter and dark energy in the solar system The new idea defines the spacetime is wave, and it is the dark matter and dark energy. And the dark matter has negative gravity. That can explain the flat structure of the universe by a balanced structure between matter and dark matter. The matter likes boats, and the dark matter likes water. There is dark matter in the solar system which floats in the dark matter. And they build up a balanced (structure) system \subsubsection{Spacetime Structure, Massenergy?Structure, and Explanation of Hubble's Redshift, Dark Matter, and Dark Energy} \label{subsubsec:spacetime} \underline {http://meetings.aps.org/Meeting/APR19/Session/G16.9} \subsubsection{New Einstein Field Equation Explain of Structure of Fluid} \underline {http://meetings.aps.org/Meeting/APR18/Session/F01.48}
