Something dramatic occurred over thirteen billion years ago when finite matter was squished by the extreme gravitational pressure of a black hole causing it to experience such intense heat that it started to expand. During this expansion phase it eventually started to cool formulating particles as it did. What eventually emerged was stabilizes structures known today as galaxies. Out in the midst of 300 billion stars we stand on a 4 billion year old terrestrial rock spinning at 67,000 mph around a molten plasmic life source. The odds of us standing here are 1 in 10^340,000,000 and yet here we stand. Life in general is rare and precious beyond measure, and life here on planet earth is truly a once in a lifetime opportunity.
While Charles Darwin was in the midst of his scientific research he made some startling discoveries concerning life and remarked to his sister in a letter, "A man who dares waste one hour of time has not discovered the value of life." Life is precious beyond measure, and quite astonishing in every respect. Life is also delicate, and with that, it carries a harsh reality reminding us tomorrow is never guaranteed. Sir Isaac Newton had impacted the scientific community with many of his discoveries including time being a fundamental physical quantity. In an effort to avoid bogging down the mind with the concept of time, we can easily surmise that it marches on without the influence of events. Relatively speaking time has its limits, so to say, and once today is gone we can never have yesterday back. Simply said, life is just too short and we should not risk wasting any part of it.
