” ‘What is Time?’ takes the excellent approach of ruthlessly and logically, analysing and decoding, our dictionary definitions of Time.”
The word ‘time’ is the most commonly used noun in the English language. Time is something that is fundamental to us; 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 admitted to not knowing exactly what Time is. Yes, he wrote at length about space-time; but time, no, he didn’t understand what it was.
So, it is a word used liberally to underpin fundamental scientific hypotheses; yet its understanding is a fudge. How come? Surely it can’t be that complicated?
Rule number one: define your terms.
Too many assertions are made about Time by (otherwise) eminent academics, whilst apparently still in search of its meaning. How does that work? How can one make an assertion about something not yet fully defined, nor empirically evidenced? Indeed, how can you base other crucial hypothesis on such an ill-formed, vague or misunderstood concept or word?
Or perhaps 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 – word definition.
This web-site sets out a definitive, clear (and, unusually for time, a non-circular) definition of the word, and hence clarifies the nature of time.
En route we will stop off to look more closely at the words space, space-time and dimension…all words with multiple meaning’s that somehow get confused in their use and context.
And we will show that time has two core meanings, the dimension of change, and the ‘flow’ of change; and that space (in this context) is the dimension of position, and hence space-time is the dimension of motion.
The answers are all here – the ‘mystery’ of time is revealed in full – take your time…
