Time is not absolute, but relative because it is intertwined with space. If the Big Bang Theory is true, time was created with the Big Bang. If interested in the relativity of time, start out by reading about time dilation or the Twin Paradox (There are identical twins. One hops on a very fast rocket, and the other stays on Earth. When the one on the rocket returns, s/he will be younger than the one who stayed.)
Everything we see if technically the way it was in the past since it takes time for light to reach us. When you look at the moon, you’re seeing it as it was over a second ago, the sun, eight minutes ago, and Polaris (North Star), 680 years ago.
One of my favorite quotes related to time: Ha, ha! keep time: how sour sweet music is, When time is broke and no proportion kept! So is it in the music of men’s lives. And here have I the daintiness of ear To cheque time broke in a disorder’d string; But for the concord of my state and time Had not an ear to hear my true time broke. I wasted time, and now doth time waste me; For now hath time made me his numbering clock: My thoughts are minutes. -William Shakespeare, Richard II
Another quote: All joy wants eternity- deep, deep eternity! – Friedrich Nietzche
It is no coincidence that tiempo can mean both weather and time in Spanish. Tiempo comes from the Latin word tempus, which, according to wiktionary, means “what is stretched.” (http://en.wiktionary.org/wiki/tempus) This makes sense if you think of the English word “tense”- as in present tense or future tense, or in the adjective form, meaning “stretched” or “taut.”
Similarly, I don’t think the word “current” coincidentally means both “present” and the “movement of liquid or gas.”
