Revealing the Nature of Dark Matter
Dr. Dan Hooper, a Theoretical Astrophysicist at Fermilab, explores the current status of the dark matter search and some new thoughts on the nature of this mystery.
A signal of gamma rays has been observed from the center of the Milky Way, and it may be the breakthrough that we have long been waiting for. If these gamma-rays are in fact being produced by the interactions of dark matter particles, they promise to reveal much about this elusive substance, and may be a major step toward identifying of the underlying nature of our universe's dark matter.
|Revealing the Nature of Dark Matter|
|Dark Matter and Dark Energy
A collection of documentaries and lectures dealing with dark matter and dark energy thought to make up around 96% of the universe.
|The Invisible Universe
We believe that 96% of the mass and energy content of our Universe is invisible. Some is in the form of Dark Matter whose presence we can only detect by its gravitational influence. The majority, called Dark Energy, appears to be ripping our Universe apart.
|Dark Matter in the Universe
Professor Peter Fisher explains the problem of dark matter, the mysterious, invisible stuff that holds galaxies together.
|The Search for Dark Matter
The search for a better understanding of dark matter is carried out both out in space and deep underground, and where astrophysics meets particle physics.
|Dark Matter: Detecting Gravity's Hidden Hand
This talk presents the evidence for dark matter and introduces one of the most ambitious efforts to discover interactions of dark matter particles, using tons of cryogenic liquid in a deep underground laboratory.
|Cosmic Clue: Dark Matter Mystery
Over the past century, many diverse observations indicate that the glue holding these objects together is the gravitational pull of an invisible, elusive substance called dark matter.
|What Makes up the Dark Matter in Our Universe?
Through cosmology and particle physics we review our understanding of how our universe came into existence. Of particular interest is what makes up dark matter the source of all structure formation.
|Dark Matter Universe on the Threshold of Discovery
Astronomical observations suggest that most of the mass of the universe is in a mysterious form known as dark matter and most of the energy in the universe is in an even more mysterious form called dark energy.
|Mysteries of the Dark Universe
Unlocking the secrets of dark matter and dark energy will illuminate the nature of space and time and connect the quantum world with the cosmos.
|Frontiers and Controversies in Astrophysics
This course focuses on three particularly interesting areas of astronomy that are advancing very rapidly: Extra-Solar Planets, Black Holes, and Dark Energy.
During this course, you'll have the opportunity to study the cosmos from the modern perspective - what we know and what we're not sure about.
