Question

Read this excerpt from A Black Hole Is NOT a Hole.

Reber had just one little problem. To explore the radio energy, he needed a radio telescope—a telescope that could detect invisible radio energy—but there was no such thing at the time. So he invented one. He built it in his backyard in Wheaton, Illinois. Late into the night, Reber probed the sky with his new telescope, using it to locate the source of the mysterious radio energy.
