Question: Could the orbit pattern in solar sytems cause the expansion of the universe?

As far as we know, orbits of solar systems don’t affect the expansion of the universe. Physicists think something called dark energy, which makes up most of the universe, is causing the expansion and acceleration of the universe! Sadly no one really knows much about dark energy yet, it’s the mystery of our generation!
