Suppose an intelligent society capable of receiving and transmitting radio signals lives on a planet orbiting Procyon, a star 95 light years away from Earth. If a signal were sent toward Procyon in 1999, what is the earliest year that Earth could expect to receive a return message?

the earliest year that Earth could expect to receive a return message =2189 year

Explanation:

Given that the distance from the earth to the source where the radio signals is 95 light years. The time taken by the signal to receive a return message when the signal sent toward Procyon in 1999 is :

1999 + 2(95)

=2189

Thus; the earliest year that Earth could expect to receive a return message =2189 year

the answer would be 32*f
