evolution of the universe
- Eagle Falls (waterfallsnorthwest.com)
The Skykomish River starts its trio of large, frothy waterfalls with a thunderous cascade in a steep sided gorge, right next to the highway. Data I encountered (I think from the WDFW but I can’t remember) placed the height of the falls at 22 feet. I recently measured it at 18 feet, but that was at high flows when much of the falls were flooded over. These falls themselves are not terribly interesting, but since they are located immediately next to the road, it’s easy to reach, and when the river is running even moderately high, it’s an impressive stretch of whitewater.
- Big Bang (Wikipedia)
The Big Bang event is a physical theory that describes how the universe expanded from an initial state of high density and temperature. Various cosmological models of the Big Bang explain the evolution of the observable universe from the earliest known periods through its subsequent large-scale form. These models offer a comprehensive explanation for a broad range of observed phenomena, including the abundance of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure. The overall uniformity of the Universe, known as the flatness problem, is explained through cosmic inflation: a sudden and very rapid expansion of space during the earliest moments. However, physics currently lacks a widely accepted theory of quantum gravity that can successfully model the earliest conditions of the Big Bang.
