OK, world's fastest animal, world's fastest person — these are all fine and good, but with a serious Earth-centric bent. Indeed, there are many things in our universe that makeEarth seem like a poky planet. Considering that a year in our world consists of 365 interminable days, it mi...

Is the Universe Symmetrical? What Is Stellar Nucleosynthesis via Nuclear Fusion? How Did We Learn About the Problems Around the Hubble Tension, Hubble's Constant, & the Age of the Universe? What Are Cosmic Rays and What Do They Reveal About the Universe?
What is the 2nd fastest thing in the universe? The speed of lightis part of the geometry of space-time and the fact that light travels at “the speed of light” is almost a cosmic afterthought. Gravity and the so-called “strong force” also travel at that speed. ...
I assume we all believe that bats have experience. After all, they are mammals, and there is no more doubt that they have experience than that mice or pigeons or whales have experience. I have chosen bats instead of wasps or flounders because if one travels too far down the phylogenetic ...
the scale issue with even more scale, watching how the collected light from billions of clustered stars bends as it travels across large fractions of the diameter of the known universe. Several increasingly accurate CMB maps made from the 1960s onward confirmed similar discrepancies in the movement...
In so doing, they have gained a better understanding of light’s mechanics and the important role it plays in physics, astronomy and cosmology. Put simply, light moves at incredible speeds and is the fastest moving thing in the Universe. Its speed is considered a constant and an unbreakable ...
Finally, in 1905, Albert Einstein's theory of special relativity posited that light always travels at the same speed no matter where it is observed from. This was a big step because suddenly, the speed of light became one of the constants of the universe, and thus, more useful for measur...
When we planned our travels, we wondered how long to stay in Beijing. The capital city was our final stop in China, and we wanted to be sure we had enough time. Of course, with so many amazing options, there is never really enough time. Our goal was to appreciate each of the highli...
