The statement that the universe is one year older than the Earth might be a misunderstanding or an oversimplification. In cosmology, the age of the universe refers to the elapsed time since the Big Bang, which is estimated to have occurred approximately 13.8 billion years ago.
On the other hand, Earth is estimated to have formed around 4.5 billion years ago. This age is determined based on various scientific methods, including radiometric dating of rocks and minerals.
The distinction between the age of the universe and the age of the Earth arises from the fact that the universe as a whole encompasses many different processes and events, including the formation of stars, galaxies, and planetary systems like our own. The formation of Earth is just one of the many events that have taken place within the larger timeline of the universe.
So, it's not accurate to say that the universe is only one year older than the Earth. The age of the universe refers to the time since the Big Bang, while the age of the Earth refers to the time since its formation.
