There were several hypotheses that scientists used to try to explain what kind of an object it was, but no one could, according to the scientific community as a whole, perpetuate any of these explanations as accepted consensus. One of the scientists who had an interest in this object is Professor Avi Loeb at Harvard University. He wrote and published a popular scientific book called "Extraterrestrial". In this book Loeb make quite a few arguments that are backing up his hypothesis that this object is no ordinary asteroid or comet, it is in fact a relic from an advanced, technological, alien civilization which originates from a solar system far away from our own. Many people in the scientific community have not accepted these views by Loeb and one of them is Jonathan I. Katz who challenges Loeb's hypothesis directly. Loeb on the other hand believes that the general resistance to his views is founded in the usual conservatism and that many scientists are afraid to advocate for something like this and risk their credibility and careers. Abstract [sv] I oktober 2017 blev ett intressant objekt observerat i vart solsystem. Det presenterades flera olika hypoteser av forskare som forsokte forklara vad for typ av objekt detta var men ingen av dessa kunde ena hela den vetenskapliga gemenskapen och ingen konsensus kunde saledes uppnas. En av vetenskapsmannen som uppvisade ett intresse for detta objekt ar en professor fran Harvard University vid namn Avi Loeb. Han skrev en popularvetenskaplig bok som heter "Utomjordiskt". I denna bok presenterar Loeb flera argument som har som syfte att starka hypotesen att detta inte ar nagon vanlig asteroid eller komet, det ar en kvarleva fran en avancerad, teknologisk, utomjordisk civilisation, som harstammar fran ett solsystem langt ifran vart eget. Den har standpunkten som Loeb uppvisar har blivit utmanad av flera fysiker inom vetenskapsvarlden inte minst av astrofysikern Jonathan. I Katz. Sjalv menar Loeb att detta generella motstand beror pa gammal konservatism hos flera vetenskapsman som inte vagar sticka ut hakan och saledes riskera att skada anseende saval som karriar.
