Dali Universe is an exhibition in Venice showcasing Salvador Dali’s lesser-known works such as sculptures and glass work. It is one of many worldwide exhibitions dedicated to Dali’s art, with four other permanent collections in Florida, California, Spain, and Paris. Dali Universe is an exhibition of works by the Spanish surrealist Salvador Dali. It was […]
Quark-gluon plasma, a phase of matter made up of nearly free quarks and gluons, is currently considered the rarest substance in the universe. It was the normal state of matter in the first millionth of a second after the Big Bang and can now be created in particle accelerators. However, quark stars, if they exist, […]
The observable universe is the region of space that we can theoretically observe, approximately 92.94 billion light-years in diameter, but there may be more beyond it. Misconceptions include its size and that it represents all that exists. It is likely just one universe in a larger multiverse. The observable universe, also known as the Hubble […]
The observable universe is 156 billion light-years across, determined by the WMAP telescope. The universe is flat and accelerating, and its size is the size of space itself. The oldest stars provide an independent measure of the universe’s size. We cannot know what is beyond the universe’s boundary. The current observable universe was determined to […]
The universe will last for more than a googolplex years, with its lifespan related to that of humanity. Its geometry is a function of its overall density, with a critical value, omega, determining whether it is closed, flat, or open. Currently, the universe appears flat and is expanding at an accelerating pace due to dark […]
There are 3-7 x 10²² stars in the universe, a relatively small number. Stars are organized into clusters, galaxies, galaxy clusters, superclusters, and the Great Wall. The Milky Way has 200-400 billion stars, and there are 80 billion galaxies in the observable universe. The universe is at least 93 billion light-years in diameter. Scientists estimate […]
The Hubble Space Telescope’s 3D modeling has estimated that there are around two trillion galaxies in the universe, far more than the previous estimate of 100-200 billion. The majority of galaxies have yet to be studied, and future telescopes may reveal interesting properties. A galaxy contains billions of stars, held together by gravity. Within each […]
The expanding universe was suspected since Einstein’s theory of relativity, but it wasn’t until 2000 that evidence was found. Hubble’s redshift analysis led to the discovery that the universe is expanding at an accelerating rate, likely due to mysterious “dark energy.” Ever since Einstein’s general theory of relativity was applied to what is known about […]
Stars are moving away from Earth, indicating an accelerating universe. Edwin Hubble’s redshift observation showed stars are receding from the solar system at an increasing rate. The universe’s fate is either an oscillating pattern or infinite expansion due to dark energy. When someone looks at the modern night sky, the starscape they see is different […]
The golden universe theory proposes that matter is continually generated as space expands, resulting in a perpetual state of expansion with no beginning or end. It is an alternative to the Big Bang theory, but has been discredited due to lack of evidence. Debate between the two theories has highlighted flaws in both, but the […]
A shared universe is a setting where multiple writers create characters who can interact and impact each other’s stories. Examples include comic book series and literary works like the Cthulhu Mythos and Star Wars Expanded Universe. It differs from collaborative work as it involves multiple books with different characters, allowing events in one story to […]
