A new theory on black holes suggests they could be used as \u2018shortcuts\u2019 to travel through the universe.<\/p>\n
French physicist Pascal Koiran believes objects could be able to pierce the holes to be able to travel from one side of the universe to another.<\/p>\n
His study sheds new light on the wormhole theory after previous research suggested they would instantly collapse.<\/p>\n
Koiran now suggests that objects such as a spacecraft could travel through and reach the other side.<\/p>\n
As reported by Russia Today, the study says \u201cWe show that the particle reaches the wormhole throat for a finite value t\u20321 of the time marker t\u2032.\u201d<\/p>\n
<\/p>\n
His thoughts are that an object could pass through the wormhole portal intact and even reduce the travel time to reach another part of the universe.<\/p>\n
Wormholes are usually studied using a method known as the Schwarzschild metric, named after Karl Schwarzschild.<\/p>\n
The Schwarzschild metric gages the gravitational field outside a spherical mass on the assumption that the electric charge of the mass, angular momentum of the mass, and universal cosmological constant are all zero.<\/p>\n

However, Koiran\u2019s research was done using a less common metric known as Eddington-Finkelstein, which is a coordinate system used for black hole geometry.<\/p>\n
He mapped a path through the wormhole using the Eddington-Finkelstein metric to more theorise that a wormhole could retain stability.<\/p>\n
The study said: \u201cIt is well known that a test mass falling into a black hole does not reach the event horizon for any finite value of the Schwarzschild time variable t.<\/p>\n

\u201cBy contrast, we show that the event horizon is reached for a finite value of the Eddington\u2013Finkelstein time variable t\u2032. Then we study in Eddington\u2013Finkelstein time the fate of a massive particle traversing an Einstein\u2013Rosen bridge and obtain a different conclusion than recent proposals in the literature.\u201d<\/p>\n
The study went onto to say the behaviour of the hole does not make sense in "Schwarzschild time" due to the trajectory of the particle continuing \u201cbeyond the end of time.\u201d<\/p>\n
Although the research study provides a new theory, there is still now physical evidence of the nature of black holes.<\/p>\n
The study will be fully revealed in an upcoming issue of the Journal of Modern Physics D, but an abstract is currently available online.<\/p>\n
