I am trying to get a few key points correct regarding expansion and dark energy...
Expansion: the Universe has been expanding continuously at different rates since the singularity that caused the Big Bang. This expansion continued to take place during the interval between the inflation period and the beginning of the dark energy period, so expansion appears to be independent from dark energy. The Universe would continue to expand even if it was not experiencing a force accelerating this expansion.
Dark energy: Theoretically the force that began to dominate gravity about 7 billion years ago and believed to be the reason expansion began accelerating again.
Are these descriptions accurate? Feel free to respond to either
