Black hole theoretics discusses the nature of black holes and its proposed artificial creation for it's hypothetical application in spacecraft propulsion.

Nature of black holesEdit

Black hole

Black holes are, theoretically, dead stars. It is proposed that they are ultra-vacuums in space where light particles cannot even escape. This gives them their black spacial appearance in celestial observations, such as the local of the first suspected black hole, Cygnus X-1. Black holes have been of a long time debate, because if light cannot truly escape, then its composition must be a solid, liquid, or gas which would pose a type of composition paradox. Theoretically, after a star dies, it will become this ultra vacuum in space. The Sun in the Solar System, is thought to be a young star, so the possibility of becoming a black hole is still a long way off in terms of billions of years.

Black hole propulsionEdit

Black hole propulsion is a hypothetical concept for enabling interstellar travel, by simulating black hole energy for spacecraft propulsion. The concept was first discussed in science fiction, notably in the book Imperial Earth by Arthur C. Clarke, and in the work of Charles Sheffield, in which energy extracted from a Kerr-Newman black hole (See rotating black hole) is described as powering rocket engines in the story "Killing Vector" (1978).[1]

The idea of generating an artificial black hole using a parabolic reflector, to reflect Hawking radiation, was discussed in 2009 by Louis Crane and Shawn Westmoreland.[2] Their conclusion was that, by having a better understanding of quantum gravity, will help to determine its possibility.[3] Similar concepts were also sketched out by Bolonkin.[4]

Artificial black hole simulationEdit

The Large Hadron Collider has projects that fall within the scope of attempting to simulate, or possibly create, an artificial black hole.

Black hole time travelEdit

The possibility for time travel has often been associated with black holes, in the hypothetical nature of wormholes, whether naturally existing or artificially created. It is speculated that black holes could displace matter through the hypothetical space-time continuum. It suggests that the speed rotation inside of a black hole might be faster than the speed of light, whereby time could standstill. Under these circumstances, if something were going near the speed of light, two minutes for that object, would be the equivalent to the span of one million years for a human being. However, these conjectures are contrary to the currently known laws of physics, and theoretical general relatively.
