Our Boldest Effort to Answer our Oldest Question: Breakthrough-Listen Search for Intelligent Life

Dr. Steve Croft (University of California, Berkeley)
Feb. 8, 2023
For centuries, humans have gazed at the night sky and wondered if any intelligent life forms like us might be out there. In 2015, the Breakthrough Foundation gave a $100 million grant to the University of California at Berkeley to undertake the most comprehensive search for signals from an extra-terrestrial civilization. Dr. Croft describes the project, introduces the many radio telescopes around the world it is using in the search, and explains how modern technology, including AI, is being used to include more stars, more frequencies (channels) and more ways a signal might be sent.

I won't be upset if you delete and re-upload with fixed audio. Happy to get a live lecture.
Sure hope you can add audio to this seminar!!
Great to listen to the lecture. Thanks.
Sorry I missed this live but I am catching up now!!!🎉
Regarding the Fermi paradox, could it have been that when Enrico Fermi posed the question "Where Is Everybody" he had to be assuming that if intelligent life were to exist within the Milky Way Galaxy, they would have had to exist at a time when there technology was advanced enough to be at least a class I civilization and space faring species due to the billions of years the Milky Way has existed ... What If when intelligent life started elsewhere they evolved in such a way that they just haven't gotten that far in terms of space exploration for a multitude of reasons ... I keep thinking about Carl Sagans lectures where he describes the modern human species of the last 2-3000 years as egocentric and to think the earth is the one and only place where life exists ... just another egocentric trait of modern man wanting to be something special in the universe only to find out in so many cosmic respects how insignificant we on this earth are just a pretty insignificant and small part of the universe, this universe
1:05:30 This question deserves a numerical answer. Steve did great off the top of his head, but allow me to crunch the numbers: Assume ET sent an undirected, Arecibo-strength message. Would we detect it at Arecibo? 450 kW -- Arecibo message strength 100 lightyears -- Distance to hypothetical star 2,380 MHz -- Arecibo message frequency (450 kW) / (4pi*(100 light years)^2) / (2,380 MHz) = 1.681×10^-15 Jy This is far too weak to be detected at Arecibo.
Will quantum computing be helpful to seti and if so, how?
5:00 Talk begins
34:00 That ambulance appears to be parked, so its light & sound should not be doppler shifted. 😏
DAVID GRUSH. If he gets substantiated then it looks like Breakthrough Listen and SETI have been had over big time.
Awful audio. Good content, but it would take 5 minutes to fix and make this watchable
1:20:30 This person is catastrophically wrong. No method other than science can be a source of trustworthy information. By definition. What we mean by the word "science" is literally just those methods which produce trustworthy information.
