A senior scientist affiliated with NASA says it's only a matter of time before an asteroid or comet will bring large-scale devastation to Earth — and humans aren't prepared.
Dr. Joseph Nuth of NASA's Goddard Space Flight Center presented his research during the American Geophysical Union's 49th annual meeting, held this week in San Francisco.
"The biggest problem, basically, is there's not a hell of a lot we can do about it at the moment," Nuth said, according to the Guardian.
Nuth believes that Earth is overdue for an "extinction-level" cosmic event.
During his presentation, Nuth cited a "close encounter" with a comet in 1996, and again in 2014, when a wayward comet traveled within "cosmic spitting distance of Mars."
