Study reveals how micro black hole would implode your brain if you accidentally walked through one

It is a terrifying scenario straight out of science fiction. Pictured: NASA's illustration of primordial black holes If a black hole hit your head, the gravitational forces would tear your brain appart at the cellular level. This would kill you in the microseconds it took for the black hole to pass through What are primordial black holes? Moving at almost 450,000 miles per hour, a primordial black hole would pass through the brain in microseconds, exerting a tidal force between 10 and 100 newtons. However, scientists say that some primordial black holes could be so small that they would pass through your body harmlessly despite having the same mass as a small asteroid Primordial black holes vary in mass from 100,000 greater than the sun, to 100,000 lighter than a paperclip.
