We can't see dark matter, and some skeptics doubt its existence, but many scientists think it makes up 20-some percent of our universe.

Early stars partially composed of dark matter may have been too bloated for fusion. Chelsea Wald reports.

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.

Dr. Glenn Borchardt, Director of the Progressive Science Institute and author of The Scientific Worldview, will be with us to discuss The Scientific Worldview. Dr. Borchardt has been involved in scientific research since 1962 and authored over 275 publications and reports. According to Borchardt, the universe is macrocosmically as well as microcosmically infinite just the opposite of what is currently being assumed by todays cosmologists.

An international team of astronomers using the NASA/ESA Hubble Space Telescope has discovered a ghostly ring of dark matter formed long ago during a colossal collision between two galaxy clusters. This is the first time that dark matter has been found with a distribution that differs substantially from the distribution of ordinary matter.
