1. Scientists say that an Earth day had around 20 hours a few million years ago and that a million years from now it will have 27 hours.
The tidal acceleration of the Moon slows the rotation rate of the Earth and increases the Earth-Moon distance. Friction effects—between the core and mantle and between the atmosphere and surface—can dissipate the Earth’s rotational energy. These combined effects are expected to increase the length of the day by more than 1.5 hours over the next 250 million years, and to increase the obliquity by about a half degree.
4. The old American sitcom television program Leave It To Beaver which originally aired from 1957-1963 is said to have been the very first TV program to show a toilet and even then they only got approved to show the top of the toilet tank, not the actual toilet bowl.
6. The Forbidden City was the Chinese imperial palace from the Ming Dynasty to the end of the Qing Dynasty. It is located in the middle of Beijing, China, and now houses the Palace Museum. For almost 500 years, it served as the home of emperors and their households, as well as the ceremonial and political center of Chinese government. Built in 1406 to 1420, the complex consists of 980 buildings with 8,707 bays of rooms and covers 7,800,000 sq ft. The palace complex exemplifies traditional Chinese palatial architecture and has influenced cultural and architectural developments in East Asia and elsewhere.
