SUMMARY
The age of the universe can be estimated using Hubble's Constant, which is currently thought to range between 10 to 20 km/s/Mpc. By applying the formula Age = 1/Hubble's Constant, where the constant is expressed in km/s/Mpc, one can derive the age of the universe. For a Hubble constant of 10 km/s/Mpc, the universe's age is approximately 13.8 billion years, while a constant of 20 km/s/Mpc suggests an age of about 6.9 billion years. These calculations provide a framework for understanding cosmic expansion and the timeline of the universe.
