Charoite (/ tʃ æ r oʊ. aɪ t / CHAR-ow-ait) is a rare silicate mineral with the chemical composition K(Ca,Na) 2 Si 4 O 10 (OH,F)•H 2 O, first described in 1978.It is named after the Chara River, despite its being 70 kilometres (43 mi) away from the discovery place.
The gravitational redshift of a light wave as it moves upwards against a gravitational field (produced by the yellow star below). The effect is greatly exaggerated in this diagram. In physics and general relativity, gravitational redshift (known as Einstein shift in older literature) [ 1][ 2] is the phenomenon that electromagnetic waves or ...

The Sun is not yellow; rather, it emits light across the full spectrum of visible colors, and this combined light appears white when outside of Earth's atmosphere. Earth's atmosphere scatters shorter wavelengths of light, particularly blues and violets, more than longer wavelengths like reds and yellows, and this scattering is why the Sun ...
Samsung Gravity (original) The Samsung Gravity (SGH-T459) is a slider feature phone with a full QWERTY keypad. It was first released for T-Mobile USA. The Samsung SGH-T349 is a mobile phone available through T-Mobile and announced on May 20, 2009 that has many similarities to the original Gravity.
GravityLight. GravityLight was a gravity-powered lamp manufactured until 2019. It was designed by the company Deciwatt for use in developing or third-world nations, as a replacement for kerosene lamps. It uses a bag filled with rocks or earth, attached to a cord, which slowly descends similar to the weight drive in a cuckoo clock.
