The word 'time' is the most commonly used noun in the English language. Time is something that is fundamental to our lives. We live our lives regulated by it and we endure the seemingly ceaseless, unstoppable advance of it. But what is time - the thing, the noun, the article? Surely we know this, it must be obvious - time is so intrinsic to our existence, and so ubiquitous to our lives that understanding it can't be difficult?
In A Brief History of Time, page 1, Professor Stephen Hawking admits to not knowing exactly what time is. Spacetime, yes. Time, no.
So it is a word used liberally to underpin fundamental scientific hypotheses; yet it's understanding is a fudge. How come? Surely it can't be that complicated?
But maybe we do understand time, and it’s really a simple notion. But the overuse, or misuse, of the word has clouded the definition. Should this quandary be in the realm of physics, cosmology or philosophy? I say it’s more a matter of semantics.
The purpose of this website is to de-construct the many variable and confused notions surrounding time, and hence set out a
succinct, clear definition, and show that it has simple, though subtle, meanings. The answers are all here - the 'mystery' of time is revealed in
full - take your time...
