The rate at which the universe is expanding, or Hubble's constant, is subject to change over time due to a number of factors, including cosmic evolution, dark energy, and the distribution of matter and energy in the universe. The methods used to measure Hubble's constant can also introduce uncertainties and variations in its value.
