Relativity and Cosmology


The Analysis of Mcmonigal,lewis and O'byrne Applied to the Natario Warp Drive Spacetime

Authors: Fernando Loup

Warp Drives are solutions of the Einstein field equations that allows superluminal travel within the framework of General Relativity. There are at the present moment two known solutions: The Alcubierre warp drive discovered in $1994$ and the Natario warp drive discovered in $2001$. Recently McMonigal,Lewis and O´Byrne presented an important analysis for the Alcubierre warp drive:A warp drive ship at superluminal speeds in interstellar space would trap in the warp bubble all the particles and radiations the ship encounters in its pathway and these trapped bodies would achieve immense energies due to the bubble superluminal speed.As far the ship goes by in interstellar space, more and more particles and radiations are trapped in the bubble generating in front of it a blanket with extremely large amounts of positive energy. The physical consequences of having this blanket of positive energies with enormous magnitudes in front of the negative energy of the warp bubble are still unknown. When the ship finishes the trip it stops suddenly releasing in a highly energetic burst all the trapped particles and radiations contained in the blanket damaging severely the destination point. In this work,we reproduce the same analysis for the Natario warp drive however using different mathematical arguments more accessible to beginners or intermediate students and we arrived exactly to the same conclusions. While in a long-term future some of the physical problems associated to the warp drive science(negative energy,Horizons) seems to have solutions(better shape functions for the negative energy problem and a theory that encompasses both General Relativity and non local quantum entanglements of Quantum Mechanics for the Horizons problem) and we discuss these solutions in our work,the analysis of McMonigal,Lewis and O´Byrne although entirely correct do not have a foreseeable solution and remains the most serious obstacle against the warp drive as a physical reality
