<br/><br/> Program 3: Examines what the universe is made of by utilizing particle accelerators to glimpse fragments of the explosive process believed to have generated stars and planets. This episode features the basics: fire, water, air, and gas in addition to more complex findings of elements and matter from the creation of the Periodic Table to Einstein's famous theory of relativity.  Program 4: At night the stars are seen in the blackness of space. But is the space empty? In the 1950's an American scientist discovered that the stars in rotating spiral galaxies seem to be held together by an unseen force. Vera Rubin proposed that the space between the stars was filled by invisible stuff she called dark matter. Scientists now believe that dark matter could make up 99% of the universe. The race is now on to find this mysterious stuff hoping to determine if the universe will expand forever or end as a frozen desert or contract under the force of gravity into a "big crunch."
