What time is it?

No one really knows.

If anything is relative, time definitely is.

We got used to living in a 24-hours-a-day, 365-day years. But that’s because we live on Earth.

On Jupiter, our days would be 9.9 hours long… yet a year would be like 12 years compared to Earth.

A light year is actually a distance, so we cannot really use that either.

Did it begin with the Big Bang or was there time before?

This summer, there will be a second added to the atomic clock.

A second… fleeting moment in time, yet so much can happen.

There’s a thing called Planck Time. It is (for now, anyway) the shortest period of time which can be meaningfully measured. It is about 10^-43 of a second.

That’s 0.000000000000000000000000000000000000000001 of a second.

Too short a period of time?

According to Big Bang theory, in that time (10^-43), gravity got separated from the rest of the forces and the Universe from one incredibly tiny particle, smaller than an atom, spanned for kilometers and kilometers in diameter.

Yet not everything happens that fast. It can be millions of years before a planet finally forms from the space debris and dust. Stars live for billions of years. A good long human life is about 70 or 80 years. Minuscule compared to a planet.

With the Lord a day is like a thousand years, and a thousand years are like a day.

Peter 3:8

Time is relative.

Yet time is what we have.

Each one of us has allotted time.

No one knows how much we have.

You may live to be 104, I may live to be 27.

I don’t know.

What I do know is that we have time right now.

And the choice is ours: how do we use it?

  • Love this reflection. I read somewhere about “leap”-seconds a little while back, but I couldn’t pretend to understand what they were talking about. =)

    What I do with my time is important to me. I don’t expect to live a “long” or even “normal” life by any standards. That’s why I try to focus on making the most of life now – not later.

    • There’s a great documentary on time with professor Brian Cox called Do You Know What Time It Is – he talks about all kinds of stuff there (related to time). It’s not overly scientific, but nevertheless it’s not National-Geographic-simple either.
