Explanation:
Detailed explanation-1: -A slower expansion rate will lead to an older age of the Universe. To go back to our stretchy band analogy, if the expansion rate is faster, it will take less time for the galaxies to reach their current distances from each other. If the expansion rate is slower, it will take them a greater amount of time.
Detailed explanation-2: -Illustration of the expansion of the Universe. 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.
