science fiction wormholes! •Einstein theory is more than geometry. The geometry is constrained by the equations. And these constraints depend on the properties of matter. •It is a delicate dance between geometry and matter.
Wormholes - Galactic Library
2024年10月25日 · Wormholes are hypothetical structures in space-time allowed by the general theory of relativity. They provide short cuts through space-time that connect one region of space and time to another; potentially, these regions can be very distant from each other.
[2106.14761] A wormhole geometry from gravitational collapse …
2021年6月28日 · We discuss a proposal on how gravitational collapse of a NEC (Null Energy Condition) violating spherically symmetric fluid distribution can avoid the formation of a zero proper volume singularity and eventually lead to a Lorentzian wormhole geometry.
White Holes and Wormholes - JILA
2018年2月3日 · The complete Schwarzschild geometry consists of a black hole, a white hole, and two Universes connected at their horizons by a wormhole. The negative square root solution inside the horizon represents a white hole.
Unitary symmetries in wormhole geometry and its thermodynamics
2022年12月26日 · We start with the Schwarzschild wormhole geometry in Sect. 2 and we connect its complex geodesics with \ ( { {\,\textrm {U}\,}} (1)\) and \ ( { {\,\textrm {SU}\,}} (2)\) symmetries by using spacetime complexification. We also provide a new Euclidean metric on a Hermitian complex manifold.
r is a geodesic observer. In particular, for a constant ) redshift function, Φ (r 0, static ob. ervers are also geodesic. Thus, a wormhole ) = pulled into the wormhole. If ar < 0, the geometry is “repulsive”, i.e. observers must maintain an inward-directed …
Wormholes and holography: an introduction | The European
2022年5月16日 · Wormholes are intriguing classical solutions in General Relativity, that have fascinated theoretical physicists for decades. In recent years, especially in Holography, gravitational Wormhole geometries have found a new life in many theoretical ideas related to quantum aspects of gravity.
4. Examples of Wormhole Metrics In this section we’ll explore several speci c wormhole geometries, nd a couple of embed-dings which display wormhole throats, and compute the associated M˝ller energy. Hartle’s Toy Wormhole. Consider the metric (as found in [3]) ds 2= 2dt + dr + (b + r2)(d 2 + sin2( )d˚2) where b>0 is a constant.
A new ‘Einstein’ equation suggests wormholes hold key to …
2016年8月17日 · Wormholes, tunnels through the fabric of spacetime that connect widely separated locations, are predicted by Einstein’s general theory of relativity.
Wormholes: The Cosmic Tunnels - JYP
2023年8月10日 · The geometry of a wormhole depends on the distribution of matter and energy around it. A traversable wormhole would require exotic matter to stabilize and prevent its collapse. Exotic matter is a form of hypothetical matter that differs from the atoms and molecules that we are familiar with.
