WebThe scientists studied an image of the oldest light in the universe to confirm its age of 13.8 billion years. This light, the “afterglow” of the Big Bang, is known as the cosmic microwave background and marks a time 380,000 years after the universe’s birth when protons and electrons joined to form the first atoms. In the 18th century, the concept that the age of Earth was millions, if not billions, of years began to appear. Nonetheless, most scientists throughout the 19th century and into the first decades of the 20th century presumed that the universe itself was Steady State and eternal, possibly with stars coming and going but no changes occurring at the largest scale known at the time. The first scientific theories indicating that the age of the universe might be finite were the studie…
