“Time is what keeps everything from happening at once.”
― Ray Cummings
“Time is an illusion.”
― Albert Einstein
“Time present and time past/Are both perhaps present in time future/And time future contained in time past.”
― T.S. Eliot
Time has always fascinated me and I love reading about it. Is it linear, always moving forward? Can it stop? Can it repeat itself? Was there (will there ever be) a time when there was (is) no time?
Does it really exist or is it merely a construct we’ve created to explain things (Cumming’s explanation ).
Time is both objective – it can be measured – and, at the same time, subjectve – it can be measured differently by different people at the same time depending on their location relative to one another (Einstein’s “illusion”) .
There is this time-space continuum thing where time and space (which make the universe) are co-dependent, one cannot exist without the other (which begs the questions: “Before the universe came into being, if there was nothing, was there no time?” And, “When – if – the universe ceases to be, will time also end?” And, “If there was – or will be – something else, then it must be measurable and isn’t time a component factor?”
And then there is the multiverse thing, where every possible event occurs, only in a different universe – another dimension – all at the same time.
And if space can be bent back upon itself, then so can time (as a coefficient of space) to where the future meets the past in the present (Eliot’s observation).
Space here in this rambling does not allow me the time to write all my thoughts and questions – including the possibility of time travel and the “grandfather paradox theory”, for instance.
I don’t know if we’ll ever learn the answers.
I guess only time will tell.
