What Is Time

Moon Phases ماشاء الله
So. What is time. All our life we're measured by time. Our age, schedules, plans etc. Still remove clocks & calendars in our life, does time really exist? Why do we rush to time day in day out? Honestly I think I could cry when I look at the clock.

But even if we throw clocks away, we can see we're aging. & we can't stop that. So we must accept this as reality & we measure our age by time. We measure the days & nights of our existence by time. But what is time. On this planet, we measure our time by the movement of near objects - the sun, moon. فالق الإصباح وجعل الليل سكنا والشمس والقمر حسبانا [Q6:96] Muslims use the moon calendar & look to the baby moon for Ramadhan, Eid - similar to the Jews. Generally, we use the sun calendar which marks the position of the earth around the sun.

Both calendar have 12 months - amazingly marking one earth's revolution around the sun. It's fascinating. How did the ancient people decide it's 12 months for the earth to orbit the sun? Do they even know the earth orbits the sun? كل في فلك يسبحون [Q21:33]

The unit of "time" was measured by the rotation of the Earth. But it is now measured by the movement of cesium-133 atom. [atomic clock]

Still, that measure of time is for us on this planet. Imagine. If you ride a rocket & flew into deep space - what measure of time will it be? There's no Earth's sun & moon for your to look at. Maybe you'll take a clock. But throw that away. You just have you. & you are still aging. So how do you measure time now? Take your hand & feel your heartbeat. You physically exists as long as your heart beats. You age as your heart beats.

So this means, you yourself is your own clock
وهو الذي يتوفاكم بالليل ويعلم ما جرحتم بالنهار ثم يبعثكم فيه ليقضى أجل مسمى [Q6:60]
If I read right, even the whole universe is decaying. That's how scientists approximate its age. So the universe itself, has it's time. So will its strength, frails one day? وانشقت السماء فهي يومئذ واهية [Q69:16]

بسم الله الرحمن الرحيم
ۖ الله الذي رفع السماوات بغير عمد ترونها ۖ  ثم استوى على العرش
ۚ وسخر الشمس والقمر ۖ  كل يجري لأجل مسمى
يدبر الأمر يفصل الآيات لعلكم بلقاء ربكم توقنونIt is Allah who raised the heavens without pillars that you see, then He established Himself above the Throne. And He has subjected the sun and the moon, each running (its course) for a specified term. He regulates all affairs, explaining the signs in detail, that you may believe with certainty in the meeting with your Lord.[Holy Quran 13:2]

The Holy Quran mentions time limit (أجل مسمى) many times. I'm amazed! (◠v◠) Anyway, I tried my best, may Allah SWT Guides me. & I hope I sound sane, coz they house arrested Galileo. Though Ibn Haitham had to feign insanity & the "crazy" man wrote the Book of Optics.

I seek refuge in Allah SWT from errors.
Only Allah SWT Knows Best. والله أعلم
