Cosmology

Looking for the big picture?

It doesn’t get any bigger than cosmology: the science of how the universe began and developed. What is it made of? How is it structured? What is its eventual fate, billions of years in the future? Supercomputer models and observations from ever-larger telescopes on the ground and in space have transformed cosmology into a predictive science, providing evidence that the universe is expanding at an ever-increasing rate, propelled by a mysterious pressure called “dark energy.”
