Dark Energy Videos

The sixth in a series describing how interstellar travel throughout the universe may be possible with warp drive technology. In this episode, Dr. Richard Obousy discusses how dark energy can enable us to travel the universe by leveraging space time itself.

In what many call a "golden age of cosmology", astronomers can now observe the universe with unprecedented precision, resulting in spectacular progress in the search for the origin of the universe. Yet, for all the impressive progress, fundamental questions remain. What is the mysterious "dark energy" driving space to rapidly expand? What existed before the big bang? Is there an origin of time? Do we live in a multiverse? Our audience joined Science Friday s Ira Flatow in conversation with leading cosmologists Lawrence Krauss, Paul Steinhardt, and Lyman Page, and historian of science Helge Kragh as they discussed and debated new advances that are shaping our understanding of the cosmic order and our place within it.

Discovery-News.com: New findings bolster the argument that dark energy is the reason our universe is expanding. James Williams explores the evidence. For more space news stories, check out http://dsc.discovery.coim/space

Have you ever looked up into the night sky and wondered how far it reaches, and how it all began? Have you ever wondered what part we play on this tiny, beautiful planet? Or even about where all the different matter and energy that created our planet Earth come from? Scientists and astronomers who have studied our universe have developed theories about the its beginnings. They tell us that we, like everything else in the universe, are the results of the explosions of billions upon billions of stars.
