SETI Perspectives :
Fast Radio Bursts: Enigmatic Signals from Across the Universe
(Message 1984909)
Posted 13 Mar 2019 by robotic Post: I'm truly fascinated by the ideas behind these studies. Not the idea of alien lifeforms trying to communicate - it might after all just be an alien opening their microwave oven... but rather I'm fascinated by the idea of extragalactic origins of signals and the distances involved. It's enough to try and get one's head around the distances involved with our own galaxy but other galaxies? A whole new order. If one adds to that the idea that light travels at a fairly finite speed apart from being slowed down by gas and so on, then those signals that come from 2.5+ billion light years away are in fact coming to us from the dawn of time. Which adds another level of complexity to the paradigm. Then, if you really want this to get more complex, consider that the universe is expanding outwards, and apparently expanding at an accelerating rate and that each part is expanding away from all other parts as well. Kind of like an expanding gas cloud. Then signals arriving here from there to put it simply, are adding a mathematical calculation to the idea that I have no hope of working out. You have a source that is moving away at an ever faster rate, reaching us following, but not quite following ... that source at apparently the same rate but also moving slightly away from the plane of the trajectory of the origin or source of the signal. hmmm. I'm told that the universe is expanding outward, which indicates a central point, but that we are not "following" objects/galaxies that are further out. There is no 'further out' but rather that every part of the universe is expanding away from all other parts. So this leads me to think that those parts that are closer to the "center" of the cloud are further back in time and that perhaps we can't even see them. Let me give an example. Strike a match in a still, closed room. Blow it out almost immediately. The smell of the sulpha and the carbon molecules permeate the room in moments. There was a source, but is it possible to locate the source now that the match is out. So the Big Bang was the match head and we - the carbon molecules, are still expanding to fill the room. Red-shift and speed So are any galaxies moving toward earth? or at least galaxies moving toward our galaxy? In any case. A very interesting and thought-provoking article, and while I would think that anyone trying to contact others is more likely to be from a planet in our own galaxy, it adds to the whole project to think that there is no reason at all why intelligent life is not scattered throughout the universe. |

Posted 11 Mar 2019 by robotic Post: Welcome, Dr. Lawn. Thanks for the Introduction. Also a nice piece on Oumuamua. Interesting. I'm in the UK currently. Originally from Australia. Lived right across the road from where the Stargazers used to meed regularly. In the Australian outback. Literally. In wintertime. madness... |

Was Our Solar System “Probed†Last Year?
(Message 1984549)
Posted 11 Mar 2019 by robotic Post: If something accelerates there must be a force acting on it, otherwise it would maintain the same speed. The original article by Dr Lawn is certainly most interesting, and as I read through the following comments I came across this one which I believe refers to the apparent acceleration of the visitor. Oumuamua. One would think that there would need to be a force acting on it to achieve this, but could it not be the force originating from the Big Bang, which I believe is the same force that is causing the universe to continually expand, and at an accelerating rate? ... and was mentioned I think by another contributor? |

Windows :
boinc_5.8.16_windows_intelx86.exe wont install
(Message 556314)
Posted 29 Apr 2007 by robotic Post: Reinstall the exact version that you have - the MSI file that is being complained about is the install info for the current BOINC - so that the files for that version can be cleanly removed before the new version is added. Ah Ha! Thank you very much. Very tricky. I now have 5.8.16 cleanly installed. As this was the one recommended by the set@home website itself ... I'm presuming its the latest one. Or, is 5.9.4 indeed the latest version, the one you mention above? thanks Robert |

Posted 28 Apr 2007 by robotic Post: This boinc_5.8.16_windows_intelx86.exe won't install on my computer. It complains about not being connected to a network resource. Then complains about not being able to find the BOINC.msi file. So I'm stuck on 5.4 still. How can i solve this problem anyone please? Robert |
