19: Black Hole Dark Matter hypothesis disproved

Stream Episodes on demand from www.bitesz.com or www.spacetimewithstuartgary.com (both mobile friendly) *The Black Hole Dark Matter hypothesis disproved A new study has provided strong evidence disproving the idea that unknown populations of ancient black holes could explain the effects currently attributed to dark matter. The findings imply that the detection of gravitational waves generated by colliding intermediate mass black holes can’t be used to imply the existence of huge populations of primordial black holes early in the history of the universe. *New evidence of a water rich history on Mars New research on Martian meteorites indicates that the red planet may have been a far wetter place than previously thought. The findings provide the first clear evidence that a mineral commonly found in Martian meteorites which was considered proof of an ancient dry environment on Mars -- may have originally been a hydrogen-containing mineral -- that could indicate a far more water-rich history for the Red Planet. *Stephen Hawking’s warning of alien invasion Theoretical physicist Stephen Hawking says while he believes intelligent alien life probably does exist elsewhere in the universe – making contact with them could be as disastrous for humans as Christopher Columbus’s arrival in the new world was for native Americans. He made the comments during the launch of his new documentary Stephen Hawking's Favourite Places. *New American Spy satellite launched A new top secret spy satellite has been successfully launched into orbit for America’s National Reconnaissance Office. The NROL-79 mission is believed to involve a pair of classified Naval Ocean Surveillance System INTRUDER Satellites.
