When first discovered, quasars seemed inexplicable: pinpoint energy sources brighter than billions of stars combined, and sending forth radiation with a distinctly un-starlike signature.

He conceived an experimental set-up that would send infrared radiation through a tube of gas and into a detector, a thermopile, which would translate temperature differences into electrical current.

It could disrupt planetary orbital patterns and send tetryon radiation across a vast area of space.

External radiationtherapy uses a machine outside the body to send radiation toward the cancer.

"There is a dead zone around him, like the one around Chernobyl," he said in an allusion to the nuclear power station in Ukraine that exploded in 1986, sending radiation around the world.

By means of tiny oscillators in each ear the Follower could send and receive electromagnetic radiation.
