After a long trip across the galaxy, cosmic rays could be employed to find contraband nuclear material hidden in cars, trucks or large ocean-going containers, using a clever new device developed by astrophysicists and national security experts.
The particles generated by cosmic rays crashing into the Earth's atmosphere could reveal nuclear material and other dense objects hidden inside cars, trucks and sea containers. The objects can be detected because the particles are deflected by dense matter.
Researchers at Princeton have come up with a new method for detecting if a black hole is on a collision course with the earth. If a black hole threat is detected, they suggest using hydrogen bombs "to alter the orbit of the black hole" and push it out of Earth's path.
