Answer 1

Answer:

The current measurement of the age of the universe is around 13.8 billion years (as of 2015) – 13.799±0.021 billion years within the Lambda-CDM concordance model. The uncertainty has been narrowed down to 20 million years, based on a number of studies which all gave extremely similar figures for the age.

Earth orbits one of the hundreds of billions of stars in our galaxy, which in turn is one of hundreds of billions in the observable universe. This apparent insignificance fits with the Copernican principle that our planet is not the center of the cosmos but simply a mediocre member of a mediocre solar system.

Meanwhile there are reasons to think Earth and its life are special, perhaps even singular. Some evidence comes from the details of our planetary circumstances, as well as from the observation that certain fundamental constants of nature appear to be “fine-tuned” for life's existence.

Scientists must reconcile these conflicting ideas to understand where we fit—and whether we are alone—in the cosmos.

I HOPE ITS HELPFUL.
