Expert in space computational technology, Scott Tyson, has been an advisor to the office of the Secretary of Defense. He presented his cosmological theory, and argued that many accepted scientific notions or paradoxes about the universe are wrong.
According to Tyson, the universe is neither contracting or expanding, the Big Bang didn't happen, and multiverses don't exist. Space-time is neither created or destroyed but is a constant, and the observer plays a crucial role in the perception of this, he continued.
Tyson suggests that all physical phenomena obeys what he calls the "Unity Expression," an underlying relationship in which space-time is conserved. From this, he has construed the physical basis for gravity, and how it can be produced and used as a new, free source of energy.
Shroud of Turin Update
First hour guest, researcher L.A. Marzulli talked about new evidence for the Shroud of Turin's authenticity from Italian scientists who studied the ancient burial cloth. They concluded that the marks on the Shroud could not have been faked with technology that was available in the medieval period. The Shroud is a "message of hope," and speaks of a whole different physics that we don't even know about, Marzulli commented.
