Blog 1: Cosmic Calendar and Biology

Posted on September 3, 2024 by Michael

When we learned about the cosmic calendar in this class, I was immediately reminded of something I had learned two years ago in BSCI 1511 here at Vanderbilt, which was the biological timescale clock. I remember seeing this diagram and being really surprised by how recent humans, or even multicellular organisms, are in the history […] Continue reading →

The Cosmic Calendar

Posted on September 3, 2024 by Matthew Marcus

For me, one of the biggest challenges in studying astronomy is truly understanding the scale of space and time. When humans have walked the earth for hundreds of thousands of years, it is hard to recognize that our collective existence is a mere flash in the grand scheme of the universe’s 14-billion year life. Every […] Continue reading →

We are Lucky

Posted on April 29, 2024 by John Newell

We should be grateful for our place in exploration. Sometimes I get sad, and mope around upset that I was born at the wrong time. The phrase goes something like “born too late to explore the Earth, too early to explore the stars.” And it is so easy to get caught up in it. But […] Continue reading →

Our Voyage

Posted on March 5, 2024 by John Newell

We have an innate desire to explore. If we look at our history as a species, that seems to be consistently true from the very beginning. But the frontier of space presents a distinct challenge from previous frontiers — it is simply SO large. Large enough, in fact, that for the first time in the […] Continue reading →

Fun Fact About Gravity

Posted on February 13, 2024 by Ethan Jones

One thing that has always fascinated me is how gravity and time are interlocked. Specifically, people at higher altitudes experience time relatively faster than people at sea level. This is due to a concept called gravitational time dilation. Time dilation comes from Newton’s theory of relativity. Basically, the more gravity you feel, the slower you […] Continue reading →

The Laws of Conservation and How They Connect Us to the Universe

Posted on February 10, 2024 by Landon Peaden

New Scientist The poetically minded will sometimes refer to humanity as being made of “star stuff” to give some higher, grander description to our existence. No, we aren’t just a bunch of intelligent animals bickering with each other as we try to see who can destroy the world first as we’re flying through the vast […] Continue reading →

Blog 1 – The Cosmic Calendar

Posted on February 1, 2024 by Leni Ertel

Cosmic Calendar Image The Cosmic Calendar summarizes the history of the universe into a way that is easy for humans to comprehend-one 12-month calendar year. The universe is about 14 billions years old, so each month of the year represents a little more than a billion years of the universe’s history. Using this model, all […] Continue reading →

Our Speed Limit

Posted on January 23, 2024 by John Newell

(its slower than you think) Many people know that the laws of physics dictate that nothing – and I mean nothing – can travel faster than the speed of light. It is not possible for any object, nor any information, to exceed 299,000,000 meters per second. At first, this seems to be an incredibly high […] Continue reading →

Posted on January 23, 2024 by James Bamshad

Imagine if the entire history of the universe could be squeezed into a single calendar year, providing a perspective of how much time has truly passed in this universe. Enter the cosmic calendar, a concept introduced by the astronomer Carl Sagan. Within the cosmic calendar, each month corresponds to over 1 billion years, allowing us […] Continue reading →

Blog 1 – Light Speed

Posted on January 22, 2024 by Jack Abrams

The speed of light is a fascinating topic that has significance from everyday life to the vast expanse of the cosmos. The speed of light is the speed at which light travels through a medium, and for a vacuum, this speed has been defined as 299,792,458 m/s. This speed is almost incomprehensible to us due […] Continue reading →
