A newspaper report indicates that a scientist has discovered a soap opera within
an artificially modulated radio signal from a planet around a massive blue giant
star 4500 light years away. Why should you be skeptical of this report
immediately?
A
Because the star is so far away, the scientist could not have the time to
receive the radio signals from such a planet.
B
Because the star is so close that we should have received radio signals
from the planet years ago.
C
Because the radio signals cannot penetrate the Earth’s atmosphere from
outer space.
D
Because we are able to hear radio waves, this should have been discovered
long ago.
*E
Because massive blue giant stars do not live long enough for life to have
evolved on such a planet, let alone intelligent life to transmit radio signals.
