   We have an excellent theoretical understanding of the physics within our   
   solar system, based on experimental measurements first performed on Earth   
   and later confirmed in orbit,  but it fails at larger scales. There are   
   apparently things we can't detect and measure from here.

   "Assuming that the lambda-CDM model of cosmology is correct, dark energy   
   dominates the universe, contributing 68% of the total energy in the   
   present-day observable universe while dark matter and ordinary (baryonic)   
   matter contribute 27% and 5%, respectively, and other components such as   
   neutrinos and photons are nearly negligible."
