The Universe’s Greatest Mystery That Threatens the Fabric of Physics
Wikipedia The foundational aspect of science is that a scientific theory that explains something about the natural world must be repeatedly tested and confirmed. If it cannot apply to every situation that meets the requisite parameters, then it is not a theory. Some information or calibration is missing, and the theory will be refined. Dark […] Continue reading

The Zodiac and Ascribing Meaning to a Random Existence
Britannica The twelve Zodiac signs are the most famous (and infamous, if you talk to scientists) way of imposing order and grouping onto our lives. Personality tests, Harry Potter houses (which have to be the laziest version out there), “What sandwich am I?” quizzes, these all apply a person’s traits and responses to fundamental questions […] Continue reading
Overview
BBC Sky at Night Magazine The incomprehensible scale of the universe is intimidating to most people. Forget feeling insignificant or small on Earth as one person out of 8 billion. That’s nowhere near how it feels to realize that when the scope of the universe is concerned, Earth and humanity are much, much less than […] Continue reading
