The Dark Side Of The Universe
Δημοσιεύτηκε στις 17 Απρ 2015
For
all we understand about the universe, 96% of what’s out there still has
scientists in the dark. Astronomical observations have established that
familiar matter—atoms—accounts for only 4% of the weight of the cosmos.
The rest—dark matter and dark energy—is invisible to our telescopes.
But what really is this dark stuff? How do we know it’s there? And what
does it do? From the formation of galaxies to the farthest reaches of
space, it appears that darkness rules. Without dark matter and dark
energy, the universe today and in the far future would be a completely
different place. We were joined by leading researchers who smash
together particles, dive into underground mines, and explore the edges
of the known universe in search of clues to nature’s dark side.
