The thermodynamics of a black hole
Glossary
AdS/CFT duality
duality that exists between 2 completely different regions and in a holographic universe would describe that structure of that universe. Often referred to as a correspondence. To satisfy any misconceptions, the solution itself is called the holographic principle, also referred to as the holographic universe, but the background theory that supports it is called AdS/CFT duality and is what changes our model of physics. Also called the holographic principle or gauge-gravity correspondence
Anti-de-sitter
space with negative curvature
Conformal Field Theory
type of quantum field theory, hence gravity cannot exist. Created using scale invariant fields and branes in string theory equivalence between two regions, meaning a set of rules in one region implies the same set of rules in the other despite the regions being completely different. The most basic is wave-particle duality, which states that a wave and a particle are the same thing, even though they appear completely different
Duality
Entropy
amount of disorder in a system; the messier it is the higher the entropy
Event horizon
edge/boundary of black hole
Hawking radiation
thermal emission from black hole
Hologram
generating a 2-dimensional image in a 3-dimensional manner
Information
vague definition, like definition of entropy. It refers to the properties that describe a system, for example mass or charge experiment that uses lasers and mirrors to merge diverse sources of light to create an interference pattern equation that links two points in space, the most basic and well-known is Pythagoras theorem mathematical representations of particles in the form of waves; negative modes correspond to antiparticles a problem in science that has no solution, implying that our knowledge of the universe is incomplete
Interferometer
Metric
Modes
Paradox
Photon
particle of light
Plank level
at a quantum level, the smallest unit of measurement
Quantum entanglement
the connection between 2 particles that relates their properties. If particle A has a property, like spin of state ½, particle B must have spin of -½. Think of this as an invisible rope that is between two particles that can be any length, and a signal traveling down this rope travels in less than a second, regardless of length of the rope
Quantum gravity Schwarzschild black hole
a theory that explains gravity at a quantum level, in the terms of particles
simplest type of black hole with only mass and no charge or spin
Space-time
the 4-dimensional universe we live in, 3 spatial dimensions and 1 temporal dimension
String theory
an unproven theory that seeks to unite general relativity and quantum mechanics
Virtual pair production
creation of two particles in a vacuum which immediately annihilate each other (often called quantum fluctuations)
