Age of the universe

A conclusion from one mathematical model, says that the age of the Universe is about 26.7 billion years: that was published July 2023 in  Monthly Notices of the Royal Astronomical Society''."

History
In the 1800s, evidence from geology showed that the Earth was at least millions of years old. Later, it was thought that the universe was unchanging. However, in the 1920s, Georges Lemaître and Edwin Hubble determined that the universe was expanding (see Hubble's law). Although the estimates made using the initial data were low, radioactive dating on Earth could be used to give measurements of 11–20 billion years to 13–15 billion years. Eventually, scientists were able to make much better measurements using spacecraft.

 Possible future 
Unknown, though there are various theories to explain the possible future of planet Earth. There are various scientific theories that explains how the Earth might end. Among of them, one of the most popular theories is that the Sun will eventually become a red giant and consume the Earth.Blackman, Joshua; Bennett, David; Beaulieu, Jean-Philippe 2021.

However, there are other logical theories that explain how the Earth might end.
