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 $2001$. However one of the major drawbacks that affects both warp drive spacetimes are the collisions with hazardous interstellar matter (asteroids, comets, interstellar dust etc) that will unavoidably occurs when a ship travels at superluminal speeds across interstellar space. The problem of collisions between a warp drive spaceship moving at superluminal velocity and the potentially dangerous particles from the Interstellar Medium $IM$ is not new.It was first noticed in $1999$ in the work of Chad Clark, Will Hiscock and Shane Larson.Later on in $2010$ it appeared again in the work of Carlos Barcelo, Stefano Finazzi and Stefano Liberatti. In $2012$ the same problem of collisions against hazardous $IM$ particles would appear in the work of Brendan McMonigal, Geraint Lewis and Philip O'Byrne. Some years ago in $1999$ Chris Van Den Broeck appeared with a very interesting idea. Broeck proposed a warp bubble with a large internal radius able to accommodate a ship inside while having a submicroscopic outer radius and a submicroscopic contact external surface in order to better avoid the collisions against the interstellar matter. The Broeck spacetime distortion have the shape of a bottle with $200$ meters of inner diameter able to accommodate a spaceship inside the bottle but the bottleneck possesses a very small outer radius with only $10^{-15}$ meters $100$ billion time smaller than a millimeter therefore reducing the probabilities of collisions against large objects in interstellar space. Recently a very interesting work appeared.It covers the analysis of Siyu Bian, Yi Wang, Zun Wang and Mian Zhu applied to the Alcubierre warp drive spacetime. But the most important fact: their analysis also applies to the Natario warp drive spacetime.In this work we applied the analysis of Siyu Bian ,Yi Wang, Zun Wang and Mian Zhu to the Natario-Broeck warp drive spacetime and we arrived at the following conclusion: The analysis of Siyu Bian ,Yi Wang, Zun Wang and Mian Zhu proves definitely that the Natario-Broeck warp drive spacetime is the best candidate for a realistic interstellar space travel.
