Explanation:
Detailed explanation-1: -Measurements made by NASA’s WMAP spacecraft have shown that the universe is 13.7 billion years old, plus or minus about 130, 000 years.
Detailed explanation-2: -By measuring how the Universe expands over time, we can come to know what forms of matter and energy are present within it. Scientists confidently state that it has been 13.8 billion years since the Big Bang, with an uncertainty of less than 1%.
Detailed explanation-3: -Far from being 13.8 billion years old, as estimated by the European Planck space telescope’s detailed measurements of cosmic radiation in 2013, the universe may be as young as 11.4 billion years. If that is, indeed, the case, then Methuselah is one again older than the universe.
