Wormholes and Black holes have played a huge mystery in the field of science as well as in science fiction, like Spidersilk the novel. Recently, these two phenomenon have had a lot of talk in science communities. More recently, a study was published the theorized that black holes could actually have a back door.

This discovery helps with other theories like that of quantum entanglement too.
