The discussion explores the possibility that dark energy may have originated from a source preceding the Big Bang, but acknowledges that this remains untestable. Dark matter and dark energy are confirmed to exist within our solar system, comprising about 95% of the universe's mass-energy content. Observations suggest dark matter could influence gravitational interactions, potentially affecting planetary orbits. However, calculations indicate the amount of dark matter in the solar system is minimal, roughly equivalent to the mass of a medium-sized asteroid, making detection unlikely. Overall, while dark matter and energy are integral to cosmic structure, their effects within our solar system are challenging to measure.
