__________________________________________________________ 1 of 6 The Extraterrestrial Contact Window by Arman J. Calbay * Abstract For decades, and even now, our expectation of alien contact has only existed in terms of direct physical contact. It does not take into account, however, an obvious phenomenon of the Universe – the enormous distances between cosmological objects. We propose the model, which is based on an interaction between civilizations of different planets, where information exchange and direct contact are significantly separated in time. Any civilization, including earth’s, will be granted a safe Extraterrestrial Contact Window, the size of which depends on the distance between civilizations and the achieved speed of spaceships. An important conclusion is that good morality in inter civilizational interaction has a greater chance of prevailing than the so-called evil civilization, the spread of which is impeded by a barrier of the size of a sphere of several thousand light years. Furthermore, this paper places great importance on finding a technology based on quantum entanglement, as this could potentially give us the ability to exchange information instantaneously, i.e., with infinite speed. Key words: Galactic communication, SETI, Quantum entanglement INTRODUCTION The SpaceX rocket engine tests, the SETI projects, the first of which is over 60 years old (Kaplan 2009), and the development of the physical theory of space-time – all these efforts reflect our longing for outer space (Ćirković & Balbi 2020; Kipping et al 2020). The search for alien intelligence is equally interesting for scientists and business (Clery 2020) and even more so for the general public. Mankind sees the vastness of the Universe and dreams of being in its most distant corners or at least on some of the nearby extrasolar planets in our galaxy the Milky Way. Despite the intense interest, 60 years of active radio scanning of the surroundings of the nearest stars have so far yielded only zero results. We believe that some adjustment or even a change in the very concept of alien contact is necessary, and we have ventured to come up with some ideas that can bring researchers' expectations closer to reality. It is quite obvious that the distances between objects in the Universe are immense; no scientist has ever disputed this. It is surprising, however, that this fact has not been incorporated in a scheme of possible relationships between civilizations of different planets. At the present moment, it is the case that earthlings expect alien contact to be in the form of direct physical contact, i.e., the arrival of spaceships, direct conversation and exchange/demonstration of technology, etc. Additionally, they fear that the alien civilization will be more advanced although Frank Drake, the SETI pioneer, viewed interstellar distances as a barrier for direct contact and he considered earthlings’ fears of enslavement by aliens as just science fiction. However, people still crave direct contact, don’t they? For many years, the concept of possible interaction with alien civilizations has remained the same: full direct contact and the assumption that alien ships will travel through wormholes * Email: arman@caa.columbia.edu
