Not what our everyday experience considers fluid stuff. Well, in physics and engineering, fluid dynamics embraces what typically are referred… Continue reading The cosmos is like a fluid?
So, on the 10^n scale, today Space.com posed the interesting question “What Is the Biggest Thing in the Universe?” Scientists have created the first map of a colossal supercluster of galaxies known as Laniakea, the home of Earth’s Milky Way galaxy and many other.
