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.
Suppose it is known that of all the planets currently in existence, Earth is in the last batch, formed only after 80% of the others in the batch. This information:
- Strengthens the author’s argument
- Weakens the author’s argument
- Completely invalidates the author’s argument
- Does not affect the author’s argument
Explanatory Answer
The author’s argument is that if we have not encountered aliens till now, it is because we have not given the exercise enough time - the universe is still churning out potentially habitable planets.
If its is known that the Earth’s formation was a comparatively recent event, that is, the Earth was formed only after 80% of the planets in the last batch were formed, then given that Earth is an early bloomer (one of the earliest planets to evolve life), it stands to reason that it is because we haven’t given it enough time that we haven’t met aliens.
