The Speed of Light In Respect to the Scale of the Universe

Posted on September 3, 2024 by Justinc

Distances in space is so great that it needs to be measured in how long it takes for light to travel to that location. Light travels around 299,792,458 m/s or about 671,000,000 mph. Compared to the speed of sound on Earth, which is about 373m/s or about 767 mph, the speed of light is more […] 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 →

Blog 1: Scale of the Universe

Posted on January 23, 2024 by Ethan Jones

It is difficult to truly grasp the size and scale of our universe. And while using units like light years might be helpful in some cases, it can also be helpful to put things in a scale that is more common in everyday life. This image helps me understand the scale of the universe in […] Continue reading →

The Universe is HUGE

Posted on January 22, 2024 by sabrinaalperin

Size: Planet vs. Solar System. vs. Galaxy For as long as I can remember, I have been fascinated by the vastness of the Universe and how everything around us has been untouched by humans. Everyone lives on Earth (unless you are an alien…). Yet, Earth is only one of eight planets in our solar system. […] Continue reading →

Final Thoughts..

Posted on April 27, 2023 by dougkyles422111

Blog 8? That doesn’t sound right. It feels like yesterday I designed my website and wrote my first post. Throughout the course of Astronomy 2110 I have explored the universe in many aspects. What sticks with me most, however, is how exactly we got to our current deep understanding of the universe.  Would Kepler have […] Continue reading →

The Scale of the Universe and Us

Posted on January 22, 2023 by cuia2

     Reading the graphic in the textbook called “Our Cosmic Address”, I got a sense for the first time of how small of a planet we live on. Earth is a typical planet rotating by a typical star we call the Sun which is only one of billions of stars in the Milky Way which is […] Continue reading →

Pondering Scale

Posted on January 20, 2023 by dougkyles422111

The Video “Powers of 10” impacted me so profoundly as I viewed it for the first time that I took a minute after watching to consider how insignificant we technically are in this universe. Earth may be the setting for every idea, individual or event that we know of, but there are infinite bounds of […] Continue reading →

“Powers of Ten” and the Scale of the Universe

Posted on January 30, 2022 by Brian

I didn’t remember until I started the video, but I had seen “Powers of Ten” before in some science class many years ago. This staying power, evidenced by my recollection and the countless Youtube comments saying similar things, is proof of how mind-blowing the concept of scale is. Scale determines what we can comprehend andContinue reading ““Powers of Ten” and the Scale of the Universe” Continue reading →

Speed of light and distance

Posted on January 19, 2020 by remieri

It is a nearly universal maxim of science fiction that faster than light (FTL) travel must exist. Let us take a look at why this is universally necessary for the sake of a good story by comparing the size and scope of both our real universe and a few fictional universes to how long traversalContinue reading “Speed of light and distance” Continue reading →

The Universe as the United States

Posted on January 21, 2019 by Andrew Talley

If there’s one straightforward lesson from astronomy, it’s that we’re tiny. We’re small compared to the Earth’s vast size, which is small compared to the sun, which is tiny compared to the space that contains our solar system, which is a tiny dot in one arm of the Milky Way galaxy, which is one of … Continue reading The Universe as the United States → Continue reading →
