The Vast Size of the Universe
by BBC Earth Website Looking up at the sky from Earth, the universe seems like it can fit in the palm of your hand. In previous years, before we truly had an understanding of how big and old the universe was, we believed that Earth was at the center of the universe and all the … Continue reading The Vast Size of the Universe → Continue reading
The Cosmic Calendar and the Cosmic Perspective
Shrinking the history of the Universe down to fit into the time frame of one Earth year may not seem all too impressive at first. The realization however that, fit into a calendar year, each month is representative of about one billion years, while each day is 40 million years, presents one with the inescapable … Continue reading The Cosmic Calendar and the Cosmic Perspective → Continue reading
Solar Eclipse: When and Why
In honor of the solar eclipse that happened in late august, I thought I’d talk about the phenomenon. A solar eclipse happens when the moon gets between the earth and the sun, and the moon casts a shadow. It should be known that the fact that solar eclipses can happen at all is a total … Continue reading Solar Eclipse: When and Why Continue reading

The Last 2 Minutes of History
Down on Earth, it’s easy to think the passage of 100 years is a long time. After all, it’s certainly longer than a human’s life expectancy. However, after hearing that modern humans can only be accounted for in 2 minutes of history, it’s hard to believe that the time spanning from the origins of modern … Continue reading The Last 2 Minutes of History → Continue reading

What is Astrophysics?
I thought I’d start my blog off by talking about what I am most interested in, Astrophysics. While I am a physics major, my passion is astrophysics and studying the life and death of stars. Astrophysics applies the laws of physics and chemistry to explain the birth, life, and death of stars, planets, galaxies and … Continue reading What is Astrophysics? Continue reading
A Speck on a Speck in a Speck in a Speck…
Humans are very arrogant creatures, and we often forget just how small we are in relation to the rest of the Universe. So much so that our units of measurement are very impractical to use on a larger scale, so we will mostly be using light seconds, minutes, hours, day, months and years to talk about […] Continue reading
First Galaxies Formed Today
…according to the cosmic calendar. The cosmic calendar is a visualization method to help comprehend the age of the universe. This calendar puts the beginning of the universe at the start of the first of January, and the end of December 31st at our current point in time. In this demonstration model, January 22nd (today!) … Continue reading First Galaxies Formed Today → Continue reading

Seasons, Solstices and Equinoxes
What causes the seasons? Not only is this asked on page 32 of Chapter 2, but it is often asked by many individuals residing on Earth. However, a surprisingly few number of people actually know. Seasons occur because the title of Earth’s axis causes sunlight to fall differently on Earth at different times … Continue reading Seasons, Solstices and Equinoxes → Continue reading
