![Since dark matter and dark energy can't be seen, how do we know that they exist?
O They can be "felt" and measured by sensitive scientific instruments
O They are the only way we have found to explain the structure of the universe - the clusters of
galaxies, etc.
O They are predicted by Einstein's theory of relativity, and Einstein is always right
They actually can be seen, just not in the visible spectrum as they emit radio waves instead of
visible light.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0caf8f5e-a4e8-4876-9244-ea0a06fea2f2%2Fa59a0460-2b73-4c7b-ad3a-959804bba3c8%2Fdi0o3g_processed.jpeg&w=3840&q=75)
