Meanings
-
(uncountable) The branch of astronomy or physics that deals with the physical properties of celestial bodies and with the interaction between matter and radiation in celestial bodies and in the space between them.
The fact is, dark energy is the biggest mystery in science. It has driven a huge amount of research in the past decade, and was a key driver in last year’s “New Worlds, New Horizons” report from the National Academies of Science, which prioritized future astronomy and astrophysics projects.
