"Dude, you totally should! I suggest you support Hufflepuff but I don't suppose you will. Well... there's a one in four chance that you root for Hufflepuff; the odds aren't in our favour," the young man added, more to himself. Heh. In truth, it didn't matter who cheered for them. The stands could ALLLLLL be bigging up the opposing team, and Hufflepuff would still be in with the same chance of winning. It was simple.
But STILL.
Jake sighed; so many people hadn't met Kazi... 'twas sad.
Heh.
"I never really understood the concept of a lightyear. Is it a distance then? Like... why is it 'year'?" Possibly the simplest of Astronomy concepts... and he didn't get it at all.
Risu grinned. "Well, this
dude was a Slytherin, once-upon," he said, clearly amused by this exchange, "but who knows, if the Hufflepuff students were to do their homework diligently, he might just change his mind and transfigure the old green-and-silver scarf..."
Risu was a terrific pedagogue.
"It
is a confusing concept to grasp at first, certainly," he said with a nod. "Simply put, a lightyear is the distance light travels in one year. It seems unintuitive at first because, as you correctly pointed out, the year is a measurement of time, not distance."
He paused briefly. "You were not here last term, unfortunately, but this is one of the topics we discussed in class. The scientific revolution 150 years ago, of Einstein's ideas about space and time, made it possible. Space and time are intertwined, an inseparable construct that we call, naturally enough, spacetime. In this construct, a measurement unit such as a year can serve to define distance."
