The Speed of Light: Can We Go Faster?
The speed of light in a vacuum is around 300,000,000 meters per second (for those more accustomed to freedom units, that’s 186,282 miles per second). Thanks to Albert Einstein and many other prominent scientists, we believe that only massless particles like photons are able to achieve this speed. This implies that it’s theoretically impossible forContinue reading “The Speed of Light: Can We Go Faster?” Continue reading

The Cosmic Calendar
What is the Cosmic Calendar? Carl Sagan, a famous astronomer, promoted this idea of the cosmic calendar, that essentially is a tool used to help people visualize and understand how far apart events in the Universe are. Sagan has chronologically arranged the hallmark events of the Universe’s 13.8 billion year life span into just aContinue reading “The Cosmic Calendar” Continue reading
Is there such a thing as the present?
Did you know that the speed of light is around 3.00 × 108 m/s? For now, it is believed that there is nothing faster than the speed of light, which is why large astronomical distances are often denoted by light-years, the distance that light can travel in a year. If we were to see a galaxyContinue reading “Is there such a thing as the present?” Continue reading
At the Edge of Knowledge
Light is definitely the single most important measure for scientists to study our universe. Since universe first became transparent 380,000 years after the Big Bang, thanks to its incredible properties, light has enabled humans to learn a great deal about universe as far as 45 billion light-year away from earth. Therefore, it is crazy toContinue reading “At the Edge of Knowledge” Continue reading

Feeling Dizzy Yet? 💫
This isn’t your everyday Milky Way time lapse video. This video, captured by Eric Brummel, is sky-stabilized with the Earth in view to show our planet’s daily rotations. It’s amazing, isn’t it? We don’t think about it often during our daily lives, but every single second, we’re moving vast distances across space. Your glass on … Continue reading Feeling Dizzy Yet? 💫 Continue reading

Hi! My name is Swarna. I am from Memphis, TN. I chose a picture taken by me at my recent vacation to the Grand Canyon. The snow was a complete surprise, as we assumed it did not snow in the desert. According to this article, other areas of Arizona also experienced some snow. This wasContinue reading Continue reading
