- The heat death of the universe (also known as the Big Chill or Big Freeze) is a hypothesis on the ultimate fate of the universe, which suggests the universe will evolve to a state of no thermodynamic free energy, and will therefore be unable to sustain processes that increase entropy. Heat death does not imply any particular absolute temperature; it only requires that temperature differences or other processes may no longer be exploited to perform work. In the language of physics, this is when the universe reaches thermodynamic equilibrium. The Heat Death theory has become the leading theory in the modern age with the fewest unpredictable factors.
- 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.
- National Nordic Museum (Wikipedia)
The National Nordic Museum (previously Nordic Heritage Museum and then Nordic Museum) is a museum in the Ballard neighborhood of Seattle, Washington, United States, dedicated to the Nordic history, art, culture, and the heritage of the area’s Nordic immigrants. It was founded in 1980 as the Nordic Heritage Museum, moved into a permanent, purpose-built facility in 2018 named the Nordic Museum, and was designated as the National Nordic Museum in 2019. The museum serves as a community gathering place and shares Nordic culture by exhibiting art and objects, preserving collections, and providing educational and cultural experiences from Danish, Finnish, Icelandic, Norwegian and Swedish Americans. The geographical region covered by the Museum includes the entire Nordic region (Denmark, Finland, Iceland, Norway, Sweden, Estonia, the regions of the Faroe Islands, Greenland, and Åland, and the cultural region of Sápmi).
