This story begins where so many great ones do (including the unnecessarily long URL of my blog) – by making fun of Bill O’Reilly: Like many people. Bill can’t grasp how the tides operate. And, in his defense, the explanation isn’t exactly obvious to the layperson. As the moon orbits Earth, its gravitational influence produces … Continue reading Tides and the Limits of Human Understanding → Continue reading → Continue reading
To call back to the late Carl Sagan, the study of astronomy is a humbling experience. The vast scale of the Universe is beyond true understanding relative to the human experience. Yet it is through the study of this incomprehensible immensity that one develops a regard for the significance an ever growing cosmic perspective affords … Continue reading The Expanding Universality of the Cosmic Perspective is Fundamental to Human Prosperity → Continue reading → Continue reading
Gravitational Singularity, or spacetime singularity, is a point with infinitely small size and infinitely big density, gravitational force and time curvature. At that point, no physicals laws we know right now can be applied. According to the big bang theory, our universe is expanded from a universe singularity. According to current theory, when an object … Continue reading Gravitational Singularity → Continue reading → Continue reading

The first one is that “survival” is the first need … Continue reading The Dark Forest Theory → Continue reading → Continue reading

In this episode, Aliens come to Earth with seemingly peaceful and helpful intentions. They just want to help and serve man. Plot twist: they were serving man alright… for dinner. This […] Continue reading → Continue reading
Space. There is quite a bit of it. In the room I live in, there is 264 sq ft of it. On Earth, there is 196.9 million sq miles of it. But in space, it is seemingly infinite, or at least so it seems. With the Hubble constant still undetermined, and the shape of the… Continue Reading → Continue reading → Continue reading
Among all the astro bodies, black hole is unique. We all know that black holes have strong gravitation effect that nothing, even including light, is able to escape from black hole. Then, a question arises and attracts me a lot – What will black hole be eventually after it absorbs a lot of matters? Will … Continue reading What will black hole be eventually? → Continue reading → Continue reading
Four-thousand years ago, early Europeans’ connected with the Cosmos every Summer Solstice by watching the midsummer sunrise directly over the Heel Stone in what we now call Stonehenge. These early people recognized that where the sun rises and sets on the horizon cycles North and South with the seasons. Today, thousands of people gather four times … Continue reading Manhattanhenge →Continue reading → Continue reading
