is time a relative thing ???

is time a thing we just interpret through out own brain ; i mean that , istn't just that the time from the BIG BANG to the FINAL PHASE that this universe(i.e. whatever this means) is in "reality" just a blink of an eye ; maybe what we perceve through our minds as bilions of years maybe so little in reality .... What do you think ???

No - Time is a universal dimension and began at big bang for this universe. The measurement of that is in fact relative - for us the second/day/month/year thing is defined in our terms. As far as we know - there are universal constants (cesium decay), etc. that will allow universal conversion to any other reference frame.

Think of it this way.

When you were 10, a year of your life was 10% of your experience. Hence the endless summers, the tediously long school days, etc...

Now by the time you're 30 , a year is down to 3.3% of your life, relatively speaking the time you experience is a small part of the total and thus goes by faster.

Or think of it this way:

Time is the only way we can keep things from all happening in the same instance!

Time to go to the bar to watch the USC/Texas game. I'm glad we have time so that I know when the game is on. I like time other than it's a vector only going one way....
