What evidence is there for dark matter and dark energy?
Can you explain more about the research that has been done on dark matter and dark energy?
Researchers have been studying dark matter and dark energy for decades, using a variety of methods including observations of the cosmic microwave background radiation, gravitational lensing, and the behavior of galaxies and galaxy clusters. While there is still a lot we don't know about these phenomena, ongoing research is helping us to better understand their properties and behavior.
