Detailed explanation-1: -The Solar System has nothing on the Universe. It’s been around for 13.8 billion years, give or take a few hundred million. That means the Universe is three times older than the Solar System. Astronomers think the Milky Way, is about 13.2 billion years old; almost as old as the Universe itself.
Detailed explanation-2: -Scientists’ best estimate is that the universe is about 13.8 billion years old. But, like so many of the largest-scale properties of the universe, we are not entirely sure about its age.
Detailed explanation-3: -How Old is the Universe? Until recently, astronomers estimated that the Big Bang occurred between 12 and 14 billion years ago. To put this in perspective, the Solar System is thought to be 4.5 billion years old and humans have existed as a genus for only a few million years.
