What is energy and matter at the same time?

Not good! Einstein theorized that it should be possible to convert matter into energy. From Einstein's theories, scientists were able to harness the energy of matter beginning in the 1940s through nuclear fission. The most spectacular example of this process is a nuclear explosion from an atomic bomb. A more peaceful example of our use of this fact of nature is the production of electricity from controlled fission reactions in nuclear reactors. http://www.physicalgeography.net/fundamentals/6a.html Mar 29 09, 1:20 PM

Dark matter and dark energy. "Dr HongSheng Zhao, of the University’s School of Physics and Astronomy, found that the puzzling dark matter and its counterpart dark energy are so closely intertwined that it’s not clear that they’re even two different materials." http://www.dailygalaxy.com/my_weblog/2009/02/could-dark-matt.html Mar 29 09, 1:29 PM
