Seti Definition and 30 Threads

My hypothesis: A sequence with the gravitational waves detected, sent by modulating radio waves, could be received and used by other intelligent beings to find the corresponding sequence within their records and then compare it to calculate our spacetime position in relation to theirs. As...

Hi! Just in case someone is interested in SETI, I made a video about the most promising radio signals detected so far. Here it is: https://www.youtube...h?v=4MxNEfIfQjI Hope you enjoy it! What is the most promising SETI radio signal for you guys? Do you think we will discover an intelligent...

I get the idea of radio astronomers listening at certian wavelengths (around the quieter area associated with the H+ and OH- "water hole" in the EM spectrum) for signals--perhaps mathematical in nature, like successive prime numbers--but one problem occurs to me: How about the amount of time...

I am very interested in Astrobiology and just came across this 7-year old abstract by Seth Shostak (of SETI): http://www.sciencedirect.com/science/article/pii/S0094576510002195 There is a lot of emphasis on searching for biological life outside of our solar system, especially with the...

This paper; https://arxiv.org/abs/1702.03301, A VLA Search for Radio Signals from M31 and M33, discusses the results [null] of a VLA search for narrow band radio emissions from the Andromeda and Triangulum galaxies. The focus was on narrow band signals because these are the only radio signals...

There is an aspect to this SETI problem that has not yet been considered. I'd post the entire article here if I could, but the copyright is not mine for one year. (Yeah, I wrote this.) https://omni.media/all-advanced-aliens-are-in-happiness-boxes Any SETI scientist who reads this is going to...

Original source: https://twitter.com/DrReneHeller/status/724935476327624704 Instructions (copied and pasted from original source): This is a call for a fun scientific challenge. Suppose a telescope on Earth receives a series of pulses from a fixed, unresolved source beyond the solar system...

Dear PF Forum, Why in "Contact" film in 1997 if I remember. The frequency for receving signal from aliens is Hydrogen times Pi? I can understand, at least grasp, that the frequency uses Hydrogen frequency, because it's the most simple element. Can't use 92.0 MHz as Sonora Radio in Jakarta...

SETI reborn—the new search for intelligent life A new influx of money has saved the Search for Extraterrestrial Intelligence (SETI) from collapse, but what does the future hold for our quest to discover intelligent life in the Universe? Continue reading...

out to what distance in our light cone can we exclude the existence of an alien civilization broadcasting EM signals at about our current levels?

I was involved with pseudorandom series for communications. For example Gold codes and Voyger randing codes. Do these codes apply with other number systems and hence throughout the universe. Light speed communication will take years hence codes could be very long, giving very narrow bandwidth...

I've been turning something over in my head for a bit and I wanted to check some math. It has to do with how long it would take a hypothetical alien civilization to colonize a big chunk of nearby space. Over at the...

Homework Statement An advanced alien civilization residing on a planet orbiting Alpha Centauri A, a class G2V star only 4 LY away, detects radio emanations from the star Sol (our Sun) and concludes that it is of intelligent origin. The aliens decide to try and establish contact with the...

This paper marks a targeted attempt to detect SETI signals in the Gliese 581 system. The First Very Long Baseline Interferometric SETI Experiment http://arxiv.org/abs/1205.6466 Apparently more such targeted surverys are planned using candidates identified by Kepler. Given the high resolution...

Watched an episode of Brian Greenes NOVA "The Fabric of the Universe" for the 300th time and an episode of "The Universe" about M Theory and Parallel Universes. A thought/question popped into my head based on my uneducated understanding of these concepts (I was an Econ Major). * Quantum...

Why is the 21 cm line considered favorable for SETI? The WP article http://en.wikipedia.org/wiki/Hydrogen_line explains why it exists (it's a hyperfine transition of hydrogen) and states that it was hypothesized to be a natural place to search for extraterrestrial signals, but it doesn't explain...

For various reason I really really want to do the SETi reu program in one of the next two summer. If you are familiar with my past you my academic background is shaky. How can I best pinpoint target a single REU for chance at success? Has anyone on here done the SETI REU? I want to apply for...

I just watched this podcast of a lecture by Paul Davies ( http://royalsociety.org/The-Eerie-Silence/ ), which made me wonder: What's been learned so far, from searches for radio signals, about the likelihood of an alien civilisation within, say, 10 ly, 100 ly, 1000 ly... How does the data that's...

Many years ago we started broadcasting radio signals for terrestrial use which inadvertently also radiated out into space. Possibly a civilization with appropriate equipment many light years away could have already detected these signals. But recently things have changed. By some estimates...

What is new with SETI? What is new with SETI? The last I heard was that the SETI@Home project is now bundled with some other program to crunch numbers for a number of other endevors. And The Planetary Society is taking over now (is that right) and they is talk about looking for lazers...

In the recent past, I've leaned towards no. The reason being that space is a 4-dimensional haystack. Even if a region in that 4D space contains advanced extra terrestrials and we scan it, the extra terrestrials would not necessarily be using EM waves for communications. If extra terrestrials...

Jill Tarter: Why the search for alien intelligence matters Reference: http://www.youtube.com/watch?v=EszGIvRdgTE"

I got sucked into reading this wild essay by an Oxford professor regarding the significance of finding life in space whether primitive or intelligent. If you get sucked in too, and read six pages, would you agree with his startling conclusion or remain skeptical. Here's the essay...

SETI's current monitoring of RF is a noble cause (in my opinion). How can we hope to discover other intelligent life if we don't listen? But as I understand it, it is sort of pathetic in terms of the handful of frequencies they actually monitor. So this lead me to these questions: What...

I have a question about radio waves. If there was an ET civilization out there broadcasting in the EM spectrum exactly like we do, how far away could it be where we would still be able to detect it? (naturally this assumes it transmitted at the proper time for us to receive the signal, ie 40...

http://arxiv.org/abs/astro-ph/0506110 Edit: This is just in case anyone is interested or wants to take it as a point of departure, for discussion. The article does not reflect my personal viewpoint, though it might reflect yours. Personally I might subscribe to the part about postbiological...

http://news.scotsman.com/scitech.cfm?id=1028302004 Seth Shostak is to discuss this on Coast to Coast AM at 10:00 PM pacific time - about ten minutes from now. http://www.coasttocoastam.com/

No one knows for sure what caused this signal. There is a slight possibility that it just might originate from an extraterrestrial intelligence. The bright colors on the blue background indicate that an anomalous signal was received here on Earth by a radio telescope involved in a Search for...

is anyone linked to the seti program? what is the minimum computer requirments? is computer safe when in use by seti?
