Evolution of the Universe - GigaPan Time Machine Jump to: From GigaPan Time Machine Direct Cosmological Simulations of the Growth of Black Holes and Galaxies This timelapse shows the distribution of matter in a simulated universe on large scales. The density of matter is shown on a false color scale, with the densest regions in yellow and the least dense in red and black. As the universe evolves from early times (it starts at an age of 10 million years after the Big Bang) the initially small fluctuations grow through the action of gravity until in the last frame (which represents the universe 14 billion years later, at redshift z=0, the present day) there are large clusters of galaxies present with vast, mostly empty spaces in between. To carry out the simulation the equations of gravity, hydrodynamics, radiative cooling, and models for star formation and black hole growth were solved in parallel on a system of 100 million particles.

Bad Astronomy | What causes lift? Yesterday, I wrote about one of my favorite kinds of clouds: Kelvin-Helmholtz clouds, also called fluctus clouds. You can call them wave clouds, because that’s what they look like: Waves breaking over a beach. I also embedded a video from Sixty Symbols explaining them, but during that explanation the scientist, Mike Merrifield, made a bit of a flub: He said that with an airplane wing, lift is generated because air is moving faster over the top of the wing than the bottom. That part is true, but he also said that the reason the air moves faster is that it has farther to travel over the curved wing than the air moving under the wing, where the wing is flat. But this isn’t really the case! This whole video fascinates me. If only politicians understood this. I also liked his explanation of what really goes into generating lift. Lift gets tricky because it uses all three and they affect each other. Sounds simple, right? But don’t take my word for it. But what about lift?
