Blog#1 Cosmic Calendar

Posted on January 30, 2022 by Irene

I found the idea “Cosmic Calendar” particularly intriguing. Cosmic Calendar is a method to visualize the universe’s chronolUniverseling its currently understood age of 13.8 billion years to a single year (Therese). At this scale, there are 437.5 years per cosmic second, 1.575 million years per cosmic hour, and 37.8 million years per cosmic day (Therese). At this scale, on […] Continue reading →

Precession Visualized

Posted on January 30, 2022 by alexbawa

After reading the initial chapters of our textbook, I was captivated by the fact that the way Earth’s tilt changes can be dumbed down to the movement of a spinning top. It’s always fascinating seeing physics work on any scale, so I was eager to look into the subject. After a bit of searching, I […] Continue reading →

Blog Post 1 Speed of Light and Light Time Travel

Posted on January 30, 2022 by isaachuggins

Ever since I was a kid I always thought about how time travel would work. However, no as an adult, I realize that the delay of light reaching our eyes is technically time travel. Every instance you see around you is actually one trillionth of a second in the past since it took light time […] Continue reading →

Powers of Ten and the scale of the Universe

Posted on January 30, 2022 by Johann West

After reaching a scale of 10^24 meters, the camera zooms back in all the way to a single proton, which is visible and in frame at a scale of 10^-16 meters. 10^+16 meters is roughly 10 light years. With these two numbers, it also frames humans as obviously very large in comparison to a proton, …

Solstices and Equinoxes

Posted on January 30, 2022 by solarelizabeth

The seasons change as Earth orbits the sun. Earth’s hemispheres receive different amounts of sunlight during each season because of the 23.5 degree tilt of Earth’s axis. When the Earth is at a point in its orbit that the northern hemisphere is tilted toward the sun, it is summer for the northern hemisphere. This is […] Continue reading →

Can We Travel Faster Than the Speed of Light (like in Star Wars)?

Posted on January 30, 2022 by josephmaquino9

One interesting question that has crossed many minds is, “Can humans travel at the speed of light?” Movies like Star Wars and Star Trek seem to believe that we can travel at, or even exceed, the speed of light (300,000,000 m/s) as they depict spaceships capable of jumping into hyperspace. In order to assess this […] Continue reading →
