Time is an eternal moment of now

Albert Einstein has been credited with the above statement.

What he meant by it is that there is no past. Only the traces of it which are left in your brain. There is no future. Only a concept of what the future might be based on past experiences.

When I think about that my brain goes into overload. It is like the concept of infinity. Or that space is infinitely big. I have never been able to comprehend either.

What does it mean that there is no past, no future just the now? How long does "now" last? A few nanoseconds?

If you give it a number of nanoseconds you can still divide it into the past and what is still to pass. So the only answer is that "now" lasts 0 seconds. Here is where it gets mind boggling. Isn't 0+0=0? So why does time pass at all? After all, time is made up of moments that don't last.

I think it is essential to separate the human concept of time and the reality of "now". We have devised ways to be able to count the zeros to see a time line. We can project the zeros ad infinitum to get a continuous line into the future (albeit a theoretical one).

Another dimension to "now" is that it takes our brain a few nanoseconds to process what the senses have registered. So in fact we have two time lines. The actual "now" and the perceived "now". They run parallel but are not in synch. A bit like a sound track which does not run in time with the frames.

What I find hard to comprehend is that if we did not process and store all these moments of now, we would not have lives. Just incoherent random moments that do not have meaning and do not build up to anything. It might be scientific fact but because we have consciousness and are able to remember, our lives are not eternal moments of now.

Our lives are made up from memories, hopes and fears ranging from unimportant to live altering.

Thank god for that, eh?
