In almost every Si-Fi movie set in space black holes are often used as a portal to another dimension,  time or universe. Many have become fascinated with this idea while others have even wondered if this could actually happen in real life. According to an article written by  Gaurav Khanna found on livescience.com , black holes could do exactly that. Spinning black holes could open up gentle portals for hypersonic spacecraft. Sounds crazy right?

Many researchers believed that any spacecraft attempt to use a black hole as a portal could lead to a disaster, which could happen since black holes are places in space where gravity is known to pull so much to where light cannot even escape. This means that if a hypersonic spacecraft were to in fact travel through a black hole portal the chances of it returning are very slim.

However, Khanna and her team at the University of Massachusetts Dartmouth along with a colleague at Georgia Gwinnett College have studied the physics of black holes for two decades and have proved that not all black holes are the same. According to Dr. Khanna, “If the black hole like Sagittarius A*, located at the center of our own galaxy, is large and rotating, then the outlook for a spacecraft changes dramatically. That’s because the singularity that a spacecraft would have to contend with is very gentle and could allow for a very peaceful passage.”  The reason this black hole, in particular, would not cause any damage to the spacecraft is due to the relevant singularity inside of the rotating black hole being weak and not being able to cause damage to objects that may interact with it.

So what does all this mean moving forward? Will hypersonic spacecraft be able to travel through spinning black holes anytime soon? Well according to Khanna and those on her team,  right now we do not have the capability of performing experiments in or near black holes just yet. Leaving Scientist to resort to theories and simulations.

For right now we’ll just have to keep watching it happen in our favorite Sci-fi movies.
