Could Some Black Holes Have Evolved from Wormholes?

How Could Language Have Evolved?

The evolution of the faculty of language largely remains an enigma. In this essay, we ask why. Language's evolutionary analysis is complicated because it has no equivalent in any nonhuman species. There is also no consensus regarding the essential nature of the language "phenotype." According to the "Strong Minimalist Thesis," the key distinguishing feature of language (and what evolutionary th...

Wormholes are Quantum Entangled Black Holes?

Black Holes, Wormholes, and Gravitational Collapse

We study a possibility of the dynamical formation of traversable wormholes from gravitationally collapsing exotic matter clouds. For generic metric ansatz of exterior spacetimes, a crucial constraint that black holes and wormholes should satisfy is obtained through the junction conditions on the edge. As a result, it is shown that the wormhole geometry cannot be formed by following the usual Op...

Black holes and traversible wormholes: a synthesis

A unified framework for black holes and traversible wormholes is described, where both are locally defined by outer trapping horizons, two-way traversible for wormholes and one-way traversible for black or white holes. In a two-dimensional dilaton gravity model, examples are given of: construction of wormholes from black holes; operation of wormholes for transport, including back-reaction; main...

Potassium ion channels: could they have evolved from viruses?

All potassium channels share a common architecture consisting of their pore module with two transmembrane domains and a conserved filter region that selects for K ions. The current view is that the plethora of complex K channels in eukaryotes evolved from a pore module precursor via gene fusions and gene duplications. Here we suggest that this pore precursor might have originated from viruses. ...
