“It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn’t feel like a giant. I felt very, very small.”
-Neil Armstrong (maybe)
When we talk about our solar system, galaxy, universe and everything beyond; it starts to simply become unfathomable. Our relative size, to even what exists just out side of our own atmosphere, instantly becomes impossible to fully comprehend. As we venture out further into the unknown, the only true thing we can count on are our Newtonian Laws, and how they may correlate to the areas beyond human comprehension. That brings us to todays lesson. How fast is the speed of light?
The easy thing to say would be, “Like, really f*cking fast. Like as fast as anything can be fast dude. Now pass the bong.” But actually we do have a speed for it. It’s 671 million miles per hour. Or an easier correlation, 186,000 miles per second. There are other ways to break it down such as: parsecs per year, light years (hint: it’s one), astronomical units etc., but for our sake we are going to stick to MPH. Now you may think “Psh, 186,000 miles? I’ve driven more in my Honda Civic.” And that is where we are fooled by our own units of measure and comprehension.
So we’ve put together some abstract comparisons to some of our worlds fastest objects and the speed of light.
