Many people have talked about the feeling of walking outside, looking up at the night sky, and feeling small. You look out into the cosmos, see seemingly countless stars, and think that everything you do on earth is just immeasurably small. Despite many people feeling that way, few truly understand the real scope of theContinue reading “The Universe is Incomprehensibly Large” Continue reading → Continue reading
One of my favorite pastimes is observing the sky at night and seeing which constellations I can point out. While I am no expert by any stretch of the imagination, I like to think that I have a basic knowledge of several “main” constellations — Orion’s Belt, the North Star, the Big / Little Dipper,Continue reading “Observing the Sky at Night” Continue reading → Continue reading
We all know that light travels fast – 299,792,458 meters per second, to be precise. Still, if the sun were to suddenly disappear into a mysterious void, you and I on Earth would not notice for about 8 minutes and 20 seconds. Or would we? Would we not immediately feel the sudden jolt of ourContinue reading “The Speed of Light and Gravity” Continue reading → Continue reading
Something that fascinates me is the idea of scale of our universe. In particular, “scale” relative to a more traditional size/distance scale that we use more often. The metric scale, whose utility to humans generally ranges from millimeters to kilometers (measurements that we are easily able to estimate and compare), represents an indescribably minuscule spectrumContinue reading “Blog #1: The Scale of the Universe” Continue reading → Continue reading
I’m sure you have heard the phrase “once in a blue moon” which is widely used to describe rare or seldom events. However, it wasn’t until I was in high school that I learned the true origins of the colloquial phrase. After seeing an article headline announcing the occurrence of a blue moon, my friendContinue reading “Blue Moon” Continue reading → Continue reading
Upon reading this chapter, I was sort of disturbed by the reality of how infinite the universe is and how minuscule we are as humans (in the grand scheme of things). The Cosmic Calendar, a scale of the universe over the course of one year, reveals that humans would have appeared within the last fewContinue reading “Infinite Possibilities” Continue reading → Continue reading
Reading about the vast size of the universe, I started exploring the possibility of travelling through the it. One popular theory on the structure of space-time is a wormhole. It postulates a theoretical passage through space-time that could create a shortcut to a different spot in the universe. So far, we’ve thought about travelling inContinue reading “Wormhole Theory” Continue reading → Continue reading
The Cosmic Calendar is created by shrinking the life span of the entire universe down into the length of the Gregorian Calendar. In this time, a human life is less than a second long and modern humans have been around for about two minutes (The Cosmic Perspective). When I think about this, it is almostContinue reading “The Cosmic Calendar” Continue reading → Continue reading
SkyView Lite is a app for Apple that makes stargazing super easy and fun for beginners. I have personally had this app for about 9 months. It’s great fun to pull out the app on warm summer nights. Even when the light pollution in the city gets in the way, this app allows the userContinue reading “SkyView Lite” Continue reading → Continue reading
It is hard for us to truly fathom the sheer size of our universe, this is clear- the distances involved are simply too big to comprehend with just the human mind. But we have begun to understand the nature of this size, and order the magnitudes of the universe in ways we can understand. TheContinue reading “How Do We Understand the Size of Our Universe?” Continue reading → Continue reading
