• About 33.8%

• About 66.2%

• About 70%

• About 50%

What is the goal of modern cosmology regarding dark matter and dark energy?

• To measure their properties as precisely as possible

• To ignore their existence

• To find a way to interact with them

• To prove they do not exist

What was the purpose of the PANTHEON+ survey?

• To measure the precise positions of about 1,500 supernovae
