Title: The Search for Extraterrestrial Intelligence: An Overview and Reflections

Abstract: The Search for Extraterrestrial Intelligence (SETI) encapsulates the broad effort to detect technosignatures, signs of technological civilizations in astronomical data. An extraterrestrial civilization can intentionally or unintentionally produce technosignatures. Their possibility has been contemplated in both academic and popular circles since shortly after the discovery of radio waves. SETI efforts have historically been associated with radio astronomy, but optical and infrared searches are also now routinely conducted. These various projects collect both targeted and untargeted data. The signals searched for include intentional transmissions with information content, unintentional signals sent (as done from Earth routinely via military radar), and non-transmission indicators such as long-term atmospheric changes on exoplanets. Increasingly, attention is being given to targeted searches due to the rapidly increasing list of known exoplanets. The application of machine learning to the problem has rapidly advanced the field beyond anything previously possible, in terms of numbers of frequencies and targets searched per year. Limiting factors remain, such as radio frequency interference (RFI) and interstellar scintillation. However, due to several new telescopes coming online, and especially due to the commitment of the Breakthrough Listen project to funding long-term SETI work, one can look to the future of this field with cautious optimism. Even if no technosignature discoveries occur, the search efforts make other useful contributions to astrophysics, such as the fast radio bursts (FRBs) detected by Breakthrough Listen. Finally, some reflections on the implications of the SETI effort on one's faith and on the Catholic Church's life as a whole will be given.

Bio: Timothy Dolch is Associate Professor of Physics at Hillsdale College. He received his BS from Caltech and his PhD in Physics & Astronomy from the Johns Hopkins University in 2012. Before joining the faculty of Hillsdale College, he held postdoctoral positions at Oberlin College and Cornell University, both with the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) collaboration. . In NANOGrav he chairs the Education and Public Outreach Working Group. He is also a research scientist with Eureka Scientific, Inc. Primarily a transient radio astronomer, his research focuses on pulsars and using them as tools to detect gravitational waves from merging supermassive black holes. He is an author on 49 refereed publications and has taught courses in quantum mechanics, general relativity, computational physics, and astronomy. With Hillsdale students, he constructed the Low-Frequency All-Sky Monitor, an on-campus radio telescope.  Prof. Dolch is a member of the Society of Catholic Scientists.

Does anyone know of an old black and white and silent movie, I think from France, where the experimenter watched a video screen and seemed to recognize the patterns that it was of extraterrestrial  origin? Very rudimentary from the early days of movies, but was something that I can never forget. I think I saw it back in the 60s during a college film festival.

Just curious.

This comes to mind:

"A Trip to the Moon" (French: Le Voyage dans la Lune) is a 1902 French adventure short film directed by Georges Méliès."

See the Wikipedia article "A Trip to the Moon" for more details.

How about this one. Is this it?

I attended the  SETI Presentation but sadly I had to leave right away when they started the initial religion based service...I fully support freedom of religion and a group's right to conduct a meeting in any way they please, however as a courtesy to some of us it would be useful to state that religion will be discussed and or religious rituals (Any religion) performed before a scientific based presentation.

I joined this group for the science of Radio Astronomy only, and ONLY the science...no politics or religion of any kind.

A simple disclaimer would would help.

Thank you, take care and be well.

Hello all,

To be fair if you look up Hillsdale college you will notice that it seems to be a religious college. That being the case I would expect there to be some element of prayer and religion. This is not necessarily my flavor of belief but if the science they have to talk about is solid then I don’t see there being any issue. Even the most secular of presentations would have a certain amount of fluff and baloney you would have to navigate through to get to the solid core of science I don’t see this as being any different.

Just my two cents if anyone needed them.

Thanks 

Mike T.

Well if he had read this thread of the email , he would have seen this and ….

The he is a member of the Catholic Society of Scientists 

Dead give away …

Breakthrough Listen. Finally, some reflections on the implications of the SETI effort on one's faith and on the Catholic Church's life as a whole will be given.

I love the internet...

I did read the whole announcement and I have been in the past to the Vatican Astronomical Observatory website and seen talks by astronomer priests in the past and in every case they talked ONLY about Astronomy , anyway so all I'm saying is that if someone is going to have a full out religious service at the beginning of a published scientific presentation it would be  nice for that someone to have published a schedule so some of us can avoid the religious service portion and attend only the scientific portion of a presentation.

Personally I'm not into religion at all  and that's why I love science and Astronomy including Radio Astronomy.

It's common courtesy.

Live long and prosper...
