The older we get, the less we know (cosmologically)

The older we get, the less we know (cosmologically) | Funteresting Stuff |

The universe is a marvelously complex place, filled with galaxies and larger-scale structures that have evolved over its 13.7-billion-year history. Those began as small perturbations of matter that grew over time, like ripples in a pond, as the universe expanded. By observing the large-scale cosmic wrinkles now, we can learn about the initial conditions of the universe. But is now really the best time to look, or would we get better information billions of years into the future - or the past?

Psychedelic topographic Moon

Psychedelic topographic Moon | Funteresting Stuff |

The Lunar Reconnaissance Orbiter, one of my favorite space probes ever, takes amazing high-res pictures of the lunar surface. But more than that, it can map the elevations of lunar features using shadows as a guide. Knowing the angles of the Sun, the Moon, and its viewing position, it can accurately gauge the elevations of the Moon’s surface as it takes image after image, orbit after orbit.
