Life as a .05 Second Year-Old
In the novel, In Desert and Wilderness, Henryk Sienkiewicz remarks, “…he began to fear whether in the presence of far greater events, all his acts would not fade into insignificance, just as a drop of rain disappears into the sea.”On the Cosmic Calendar, the average human life span is only about two tenths of a second, […] Continue reading

Mayans Predicted the 1991 Solar Eclipse
Okay so this picture may look like just a bunch of doodles on a piece of clay, but it actually is hieroglyphs from four ancient Mayan codices that predict with surprising accuracy the 1991 Solar Eclipse. The Mayan astronomers were able to predict within a day, the time of the 1991 solar eclipse. Keep in […] Continue reading
The Speed of Light
The speed of light is very, very fast, almost incomprehensibly fast. It is unusual to think that whenever we see an object, light is bouncing off that object and hitting our eye. We perceive this to be instantaneous, but it actually takes some infinitesimal amount of time for light to travel from nearby objects to […] Continue reading

Your Zodiac Sign is Wrong: 3 Misconceptions You Have About the Night-Sky
We all get it. You’re a Capricorn or a Taurus or a Sagittarius or a(n) [any other zodiac constellation]. You’ve read all of your horoscopes, and they fit your personality soooo well. “This is so me,” you might yell to your friends, completely disregarding the fact that they don’t care which vague internet prediction you identify with.

The Universal Speed Limit
According to the Special Theory of Relativity, the speed at which light travels is the same in all reference frames. In other words, you will always observe that light will travel at 2.99*10^8 m/s, regardless of how fast you’re going. At first, one might think that this number is so high that it would make little […] Continue reading

“Goodnight Nobody, Goodnight Mush”
When we think we can’t see the moon, it can definitely see us. This doesn’t just hold true when we’re sleeping. As the children’s book, “Goodnight Moon,” goes, we may say “Goodnight” to the moon – but it’s still there outside our window and outside our atmosphere. Different parts of the moon disappear at different […] Continue reading
You are stronger than the Universe! (Kind of)

But if that’s true, why cant’t you feel it? In a way it is because you are stronger the the stretching of the universe! Well maybe […] Continue reading

Blog #2 Observation
Much of what has been covered in class so far has been from the perspective of an observer on Earth. We know that light pollution from cities makes it difficult to see starlight with the naked eye. With that in mind, observatories tend to be far away from city limits. Additionally, they tend to be […] Continue reading

Solstices & Spirituality
As we’ve learned through our assignments and reading, the spring and fall equinoxes are the times when the Sun appears to cross the equator, causing daytime to be the same length at almost all latitudes. These two days, in addition to the winter and summer solstices, held high significance in ancient spirituality. The adoration […] Continue reading
