Difference between Universe and Vacuum energy

Universe vs. Vacuum energy

The Universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. Vacuum energy is an underlying background energy that exists in space throughout the entire Universe.

Similarities between Universe and Vacuum energy

Universe and Vacuum energy have 19 things in common (in Unionpedia): Accelerating expansion of the universe, Antiparticle, Classical mechanics, Cosmological constant, Dark energy, Elementary particle, Energy, Expansion of the universe, False vacuum, General relativity, Grand Unified Theory, Gravity, Light, Particle physics, Physical cosmology, Space, Vacuum, Virtual particle, Zero-energy universe.

Accelerating expansion of the universe

The accelerating expansion of the universe is the observation that the universe appears to be expanding at an increasing rate, so that the velocity at which a distant galaxy is receding from the observer is continuously increasing with time.

Antiparticle

In particle physics, every type of particle has an associated antiparticle with the same mass but with opposite physical charges (such as electric charge).

Classical mechanics

Classical mechanics describes the motion of macroscopic objects, from projectiles to parts of machinery, and astronomical objects, such as spacecraft, planets, stars and galaxies.

Cosmological constant

In cosmology, the cosmological constant (usually denoted by the Greek capital letter lambda: Λ) is the value of the energy density of the vacuum of space.

Dark energy

In physical cosmology and astronomy, dark energy is an unknown form of energy which is hypothesized to permeate all of space, tending to accelerate the expansion of the universe.

Elementary particle

In particle physics, an elementary particle or fundamental particle is a particle with no substructure, thus not composed of other particles.

Energy

In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object.

Expansion of the universe

The expansion of the universe is the increase of the distance between two distant parts of the universe with time.

False vacuum

In quantum field theory, a false vacuum is a hypothetical vacuum that is somewhat, but not entirely, stable.

General relativity

General relativity (GR, also known as the general theory of relativity or GTR) is the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern physics.

Grand Unified Theory

A Grand Unified Theory (GUT) is a model in particle physics in which, at high energy, the three gauge interactions of the Standard Model which define the electromagnetic, weak, and strong interactions, or forces, are merged into one single force.

Gravity

Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward (or gravitate toward) one another.

Light

Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum.

Particle physics

Particle physics (also high energy physics) is the branch of physics that studies the nature of the particles that constitute matter and radiation.

Physical cosmology

Physical cosmology is the study of the largest-scale structures and dynamics of the Universe and is concerned with fundamental questions about its origin, structure, evolution, and ultimate fate.

Space

Space is the boundless three-dimensional extent in which objects and events have relative position and direction.

Vacuum

Vacuum is space devoid of matter.

Virtual particle

In physics, a virtual particle is a transient fluctuation that exhibits some of the characteristics of an ordinary particle, but whose existence is limited by the uncertainty principle.

Zero-energy universe

The zero-energy universe hypothesis proposes that the total amount of energy in the universe is exactly zero: its amount of positive energy in the form of matter is exactly canceled out by its negative energy in the form of gravity.
