Question

In the Drake Equation, suppose that the term denoting the fraction of planets that develop life was equal to one half (0.5). What would this mean

a) Half of the planets have developed intelligent life
b) Only a fraction of planets have the potential for life
c) All planets have developed life
d) No planets have developed life

Answer 1

In the Drake Equation, if the term denoting the fraction of planets that develop life is equal to one half (0.5), it would mean that only a fraction of planets have the potential for life.

Step-by-step explanation:

In the Drake Equation, if the term denoting the fraction of planets that develop life is equal to one half (0.5), it would mean that b) Only a fraction of planets have the potential for life.

The Drake Equation is used to estimate the number of intelligent civilizations in the galaxy. It takes into account various factors, including the fraction of habitable planets that actually support life, the fraction of inhabited planets that develop advanced intelligence, and the fraction of these intelligent civilizations that develop science and technology to communicate.

If the term denoting the fraction of planets that develop life is 0.5, it means that only a fraction of planets have the potential for life.
