As is explained in this fascinating Youtube video (among many), there’s a current school of thought which says that the age of the universe may be double what we previously thought: 27 rather than 13.8 billion years old. I find that intriguing I must say, although I just have to raise one small point: Could it be that the universe just feels older than it is? We all know what it feels like to age: you tire faster, your muscles feel tighter, you loose your temper more quickly. These days I sometimes feel closer to eighty than forty. Maybe this is what the scientists mean by ‘tired light’. If the universe now seems far older than it did, then, I can sympathise.
