t. e. Albert Einstein. The Einstein–Podolsky–Rosen (EPR) paradox is a thought experiment proposed by physicists Albert Einstein, Boris Podolsky and Nathan Rosen which argues that the description of physical reality provided by quantum mechanics is incomplete. [1] In a 1935 paper titled "Can Quantum-Mechanical Description of Physical Reality ...
A theory of everything (TOE), final theory, ultimate theory, unified field theory, or master theory is a hypothetical, singular, all-encompassing, coherent theoretical framework of physics that fully explains and links together all aspects of the universe. [1]: 6 Finding a theory of everything is one of the major unsolved problems in physics ...
The General Certificate of Secondary Education (GCSE) is an academic qualification in a range of subjects taken in England, Wales and Northern Ireland, having been introduced in September 1986 and its first exams taken in 1988. State schools in Scotland use the Scottish Qualifications Certificate instead. However, private schools in Scotland ...
A black hole is a region of spacetime wherein gravity is so strong that no matter or electromagnetic energy (e.g. light) can escape it. [2] Albert Einstein 's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. [3][4] The boundary of no escape is called the event horizon.
Missing baryon problem (1998 [116] –2017): proclaimed solved in October 2017, with the missing baryons located in hot intergalactic gas. [117][118] Long-duration gamma-ray bursts (1993 [113] –2003): Long-duration bursts are associated with the deaths of massive stars in a specific kind of supernova -like event commonly referred to as a ...
General relativity, also known as the general theory of relativity, and as Einstein's theory of gravity, is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics. General relativity generalizes special relativity and refines Newton's law of universal gravitation ...
The standard model is a quantum field theory, meaning its fundamental objects are quantum fields, which are defined at all points in spacetime. QFT treats particles as excited states (also called quanta) of their underlying quantum fields, which are more fundamental than the particles. These fields are.
The cosmic microwave background (CMB, CMBR), or relic radiation, is microwave radiation that fills all space in the observable universe. With a standard optical telescope, the background space between stars and galaxies is almost completely dark. However, a sufficiently sensitive radio telescope detects a faint background glow that is almost ...
