Let us consider where our rapidly accumulating store of knowledge about the universe is leading us. That it provides satisfaction to a host of curiosity-motivated physicists and astronomers is beyond dispute. However, some view it as a humbling experience in that each increase in knowledge seems to reveal more clearly our own relative insignificance in the grand scheme of things. Thus, in chronological order, we humans have come to realise that
- Our Earth is not the center of the solar system.
- Our Sun is but one star among many in our galaxy.
- Our galaxy is but one of many, and our Sun is an insignificant star in it.
- Our Earth has existed for perhaps only a third of the age of the universe and will surely disappear when our Sun burns up its fuel and becomes a red gaint.
- Our species has inhabited Earth for less than a million years – a blink in cosmological time.
Although out position in the universe may be insignificant, the laws of physics that we have discovered (uncovered?) seem to hold true throughout the universe and – as far as we know – have held since the universe began and will continue to hold for all future time. At least, there is no evidence that other laws hold in other parts of the universe. Thus, until someone complains, we are entitles to stamp the laws of physics “Discovered on Earth.” Much remains to be discovered: “The universe is full of magical things, patiently waiting for our wits to grow sharper.” That declaration allows us to answer one last time the question “What is physics?” Physics is the gateway to those magical things.
I love Physics. I love Science. Even now, when I open up a new chapter, a new topic, excitement bubbles inside of me (impatience?) to learn new things and better understand the world around me. Physics is to me like The Underground is to Versatile or NBA is to Toughtrasher 😉
What do you like? What thing matters most to you? What is it that excites that curious little brain of yours? Share it with us, and we might be able to learn from each other! On this note, I would like to end the 1000th article created on the Underground Blog. I would also like to use this opportunity to congratulate Versatile, Voltaire and all the other authors due to whom we have come this far! Lets spread knowledge!
