CLAT Logical Reasoning: Earth and Outer Space
Given the age of the universe and the apparent high probability of life evolving on other planets orbiting other stars, where are all the aliens? A 2015 study based on data from the Hubble Space Telescope and Kepler Space Telescope might offer an answer: Earth was an early bloomer. The study, focused on the likelihood of the evolution of habitable worlds, finds that when our planet was born from our young sun's protoplanetary disk some 4.6 billion years ago, it was born into an era when only " 8 percent of the potentially habitable planets that will ever form in the universe existed." Most of the material available to form habitable planets is still around — giving lots of time for alien civilizations to form and get in touch with us.
Which of the following statements is consistent with the findings of the 2015 study?
- There is a 92 % chance of us encountering life from other habitable planets
- 92% of the planets in the universe have not yet formed
- Earth became habitable as it was born early in the history of the universe
- There is at most an 8 % chance of Earth being the only planet inhabited by life in the universe
Explanatory Answer
The study found that when Earth was formed, only 8% of the potentially habitable planets that will ever form in the universe existed. In other
words, there is at most an 8% chance that Earth is the only planet inhabited by life in the universe. Option (a) is incorrect, as there is
no mention of us encountering alien life in the study. Option (b) is incorrect too, as the study only talks about potentially inhabitable planets, not the total number of planets in the universe.Option (c) is incorrect, as the study does not attribute life on earth to it evolving early in the history of the universe.
