The Size of the Universe

This video is similar to the Powers of Ten video, but it zooms in and out of the universe at a much faster pace, so it was easier for me to understand. The video starts with a view of a region on Earth and then slowly zooms out to the solar system, galaxy, and finally, […] Continue reading

Power of the Zodiac

Many of the belief system of ancient civilizations are based on what these rather primitive people observed around them, i.e. the Aztecan Sun god, the Greek gods of the sun, ocean, thunder, etc. To those ancient people who first realized the pattern of procession that the sun exhibits in it astral travels, it must as […] Continue reading

The Moon Illusion and How to Resolve It

The moon is always the same size. It seems like an easy enough concept to grasp, but it doesn’t explain why the moon doesn’t always look like it’s the same size. I’m sure you’ve all seen it. You go out early on the night of a full moon, and the moon looks HUGE. In high school, […] Continue reading

The Speed of Light and Time Dilation

Relativity is probably the most interesting area of physics in my opinion, and this video does a great job of succinctly explaining the concept of time dilation. To summarize, objects moving at speeds close to the speed of light experience time more slowly from the perspective of a stationary observer because the speed of light […] Continue reading

Farthest Supernova Yet!

A few weeks ago, it was announced that a type 1a supernova had been discovered that was 10 billion light years away! Officially named SN SCP-0401 but nicknamed “Mingus” after a jazz composer, this supernova is remarkable not just for its distance but for the detail in its spectrum. Scientist will be able to use […] Continue reading
