There’s Only One Way To Find Out A primordial black hole could be lurking beyond Neptune. A primordial black hole … "These two things point at the same mass range," Unwin said. A new telescope in Chile is on the case. Earth will not fall into a black hole because no black hole is close enough to the solar system for Earth to do that.
