British astronomer Patrick Moore announced on BBC Radio 2 that at exactly 9:47 a.m. the planet Pluto would pass behind the planet Jupiter, and that this alignment of the planets would result in a stronger gravitational pull from Jupiter, counteracting the Earth’s own gravity and making people momentarily weigh less. He told listeners that they could experience this phenomenon for themselves by jumping in the air at 9:47. If they did so, he said, they would experience a strange floating sensation. When 9:47 a.m. arrived, BBC2 began to receive hundreds of calls from listeners who claimed that they had felt the sensation. One woman claimed that she had been seated around a table with eleven friends, and that all of them, including the table, had begun to float around the room. Another caller complained that she had risen from the ground so rapidly that she had hit her head on the ceiling.
