To Infinity and Beyond: The Accelerating Universe
Δημοσιεύτηκε στις 15 Ιουλ 2015
Dark
energy is cosmology's biggest mystery—an anti-gravitational force that
confounds the conventional laws of physics. It makes up more than
two-thirds of the cosmos, but science is still grappling to explain what
dark energy actually is. In this program, top physicists search for
clues to this mystery in both the earliest moments of the universe and
far into the future of the cosmos.
