 **Abstract: ** Time travel has been theorized but has never been conclusively achieved. This study is an examination of both the ability of a person to travel backwards and forwards from their own time-reference point and demonstrate the impact such travelling can have on the individual, their immediate associates and the world at large. Using a chronology reverser, the subject was transferred from 2015 to 1950, when the subject ’ s maternal grandfather was approximately 10 years old. After terminating the grandfather, the subject returned to 2015 and noted that his family were absent as were his belongings, thus proving the possibility of interfering with personal history and yet maintaining a physical presence in the contemporary timeline. 
 
 
 **Introduction: ** Time travel has long been theorized ( 1,2,3 ). However, it is only by using a Richard Sanchez Chronology Reverser ( RSCR ) ( 4 ), can safe and applicable travel be conducted. Sanchez has published numerous works on the effects of travelling forward in time ( 5-14 ) and has thus proven that future events can be avoided. 
 
 However, there exists a gap in the literature regarding travelling back in time. Sanchez has cited the prospect as being “ close to – *burp* – impossible, Morty ” ( 15 ) and has expressed no desire to actively contribute to the current study. Chief among Sanchez ’ s documented concerns was the notion that “ you could just fucking write – *burp* – write yourself out of history, Morty ” ( 16 ). 
 
 A paper was recently published by the current author, indicating the theoretical possibility of travelling back in time and that the inherent dangers had been grossly exaggerated by Sanchez to prevent other parties from attempting to conduct their own research ( 17 ). This paper was generally well received by the scientific community ( 18,19 ), but was also vocally decried by Sanchez as being “ stupid, Morty, even for you ” ( 20 ). 
 
 At the time of publication of Ref 17, Sanchez was the eminent authority on time travel in the world. Due to his lack of cooperation, the current author decided to proceed with the proposed experiment and thus demonstrate the effects of travelling back in time. 
 
 
 **Method: ** Having acquired the RSCR, the current author ( hereafter known as “ the subject ” ) travelled to a remote location. This to mitigate any potential risk of travelling into a foreign object ( e.g. car, house, person ). The precise location is shown in Figure 1. 
 
 The RSCR was set to 1950. This time was chosen for several reasons: 1 ) the Second World War was over and the country should be less chaotic; 2 ) the subject ’ s maternal grandfather should be approximately 10 years old and thus pose no risk to the subject in the termination phase of the experiment; 3 ) it ’ s five years before Marty McFly, which makes it better, okay? Jeez. 
 
 The time portal was opened and the subject entered. Upon arriving in 1950, the subject was immediately beset by a shrieking creature with terrifying visage. After an initial miscommunication ( wherein the subject was repeatedly kicked ), the creature was correctly identified as being the subject ’ s maternal grandfather ( although, given the complexities of time travel, obviously not in this time-reference. Because that ’ d be sick, okay? ). 
 
 A brief struggle ensued, but eventually the subject was able to overpower the once-and-future grandfather. The grandfather was terminated by repeated blows to the head and... and... oh, God, Rick!... repeated blows to the head and buried within fifteen meters of the time portal. 
 
 The subject then returned to 2015 and the time portal closed. Upon arriving at the subject ’ s home, it was immediately discovered that the subject ’ s family did not live there. After questioning the current occupants of the house, it was determined that no such family had ever lived there. 
 The subject went to the library and looked up historical records. The death of Richard Sanchez was noted in 1950. No record of the subject ’ s mother ( Beth Smith ( nee. Sanchez ) ) or sister ( Summer Smith ) could be found. The subject ’ s father ( Jerry Smith ) was noted to be an adult television star on a popular homosexual channel. 
 
 **Discussion: ** Having terminated the subject ’ s maternal grandfather in 1950, the subject did not suffer any unforeseen complications. There were the expected bouts of depression and extreme guilt and regret, but for the purposes of science, the subject was able to cope. 
 
 **Conclusion: ** It is possible to travel backwards in time, no matter what Rick thinks. You can even kill... kill... oh, jeez. You can even k-k-kill your grandfather when he ’ s just a little kid and it... it doesn ’ t have an effect on the world. It ’ s like he never existed, but here you are. How does that work? I mean, come on... how can I be here if he isn ’ t? It doesn ’ t make sense. None of this makes sense. Why did I do it? Oh jeez, Rick. I know what I need to do. 
 
 **Future Work: ** Is it possible to go back in time and stop your past self from killing your maternal grandfather as a child?
