"Life, the universe, and everything" is a common name for the off-topic section of an Internet forum, and the phrase is invoked in similar ways to mean "anything at all". Many chatbots, when asked about the meaning of life, will answer "42". Several online calculators are also programmed with the Question.
Cosmology is a branch of metaphysics that deals with the nature of the universe, a theory or doctrine describing the natural order of the universe. [36] The basic definition of Cosmology is the science of the origin and development of the universe. In modern astronomy, the Big Bang theory is the dominant postulation.
The observable universe is isotropic on scales significantly larger than superclusters, meaning that the statistical properties of the universe are the same in all directions as observed from Earth. The universe is bathed in highly isotropic microwave radiation that corresponds to a thermal equilibrium blackbody spectrum of roughly 2.72548 ...
The first book was adapted from the first four radio episodes (the Primary Phase), with Arthur being rescued from Earth's destruction by Ford, meeting Zaphod and Trillian, coming to the planet of Magrathea and discovering the true purpose of Earth, and ending with the group preparing to go to the Restaurant at the End of the Universe.
Carroll claims that poetic naturalism resolves many of the conflicts caused by the fundamental differences between the various branches of science and philosophy. For example, the universe can be described mechanically in terms of atoms obeying certain laws. This results in a deterministic universe incompatible with the concepts of choice or ...
A group of physicists have theorized a mechanism for "cosmological collapse" which predicts the universe will at some point stop expanding.
The heat death of the universe (also known as the Big Chill or Big Freeze) [1] [2] 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.
Observations made by Edwin Hubble during the 1930s–1950s found that galaxies appeared to be moving away from each other, leading to the currently accepted Big Bang theory. This suggests that the universe began very dense about 13.787 billion years ago, and it has expanded and (on average) become less dense ever since. [1]
