Moon-walker claims alien contact cover-up
(Message 804363)
Posted 2 Sep 2008 by John Ståhle Post: What I am really impressed by is Et's invention of an astronomer detector. Of all the about 50,000,000 amateur and professional astronomers watching the sky 7x24 all over the world - and experienced in watching it - they have avoided detection by some 49,999,900 - marvellous feat by ET. |

Posted 25 Jun 2008 by John Ståhle Post: (Quoting myself earlier today): But we have known for years that there are complex molecules in interstellar gas-, dust- and molecular clouds, even including NH3, CH4, CH3OH and H2O.

The molecule in question is NH2CH2CN The report will appear in Astronomy & Astrophysics in a few days.

Posted 8 Jun 2008 by John Ståhle Post: I have prefs to allow for up to 8 waiting work units (pro tem. 2.74 MB) ... Who wrote "exact" - not I said the little green duck - but based on average time for execution I have set "Maintain enough work for an additional" in Computing preferences. As easy as falling down the stairs. Anyway I shall not waste time moving BOINC around, but instead wait for version 6.2.x, as I have enough problems to solve with a new BOINC on UBUNTU . |

Posted 7 Jun 2008 by John Ståhle Post: (John McLeod VII): Or wait a couple of weeks and install 6.2.x - which does the split on its own during the install. Best advice, taken. (Gundolf Jahn): But still, why should SETI request one more GiB aside from the 1.78 already available? SETI tasks usually are well below 1 MiB! I have prefs to allow for up to 8 waiting work units (pro tem. 2.74 MB) and after a clean-up I now have 4.4 GB free space, but it seems that sometimes upload are delayed, I often have 2 or even 3 completed work units waiting for upload (4 Mb/s ADSL, not dial up connection). Given that the work units only take up 2.74 MB, the need for disk space seems to be for scratch/temporary storage, as I also have 2-3 running tasks. Thanks for your input - I shall wait for v. 6.2.x = Problem solved. . |

Posted 7 Jun 2008 by John Ståhle Post: Hold on, let's start from the beginning. Where do you have BOINC installed to? And how big is this hard drive or partition that BOINC lives on? Like my first posting says: on Win2000 on my system drive (i.e. partition) C: with (C: - "only" 4GB free) and %TEMP% points to partition F: C: is 20 GB. I never told BOINC to place data on this partition, as the data partitions reside on a different physical HD, partitions E: and F:, which have 31+ and 39+ GB free.

Posted 6 Jun 2008 by John Ståhle Post: (druid): Would a warlike civilization ever beable to undertake such a demanding task as interstella travel? Look at us! If we can not stop waring against each other and our enviroment, we could be extinct before we make it to even our closet planets. I think it would be self limiting. While no one actually knows this, I tend to believe, that it takes a lot of evolutionary pressure and a Crazy Eddie or two for a species to travel to the stars. Evolutionary pressure involves fighting for survival, and probably also involves waging war on each other until one reaches the point where the next war equals extinction. . |

Posted 6 Jun 2008 by John Ståhle Post: Not only that, but *specifically addressing your issue*, Limeweaver further calculates that the "average 'Earth' in the universe, not just the galaxy, is about 1.8 billion years older than the Sun." (quoted verbatim) I most adamantly (if that is the word I want) refuse the notion that I was referring to M-dwarfs. We have a good idea of the number of stars formed in ye olde days, because since then they have reached the white dwarf stage and some of those, which happened to be members of double- or multiple star systems, have later exploded as supernovae with the type Ia signature - i.e. they originally possessed slightly sub-Solar to 7-8-9 Solar masses. Counting supernovae in distant galaxies (and assuming that they - to a reasonable extent - are like our own galaxy) tells us how many average stars were formed at different times. As for the number of stars in our galaxy, there is a lot of controversy among the chosen people, e.g.: Most of the 100 billion stars in our Milky Way galaxy are located in the galactic plane, forming a great circle around the sky, see "Team hopes to use new technology to search for ETs" http://www.spaceref.com/news/viewpr.html?pid=25598 Carroll & Ostlie (in "Modern Astrophysics", 2007 (2006), p. 886) tells us that the (roughly) estimated stellar mass in our galaxy is in the vicinity of 60E9 Solar masses (+ some 5E9 S.M. dust and gas). According to a NASA article I have somewhere, our galaxy contains 3-400E9 Solar masses ordinary matter, according to another the number is 250 Solar masses. 1/4 or 1/3 or 1/2 (or any other fraction :-) of this mass is bound in stars. According to professor Bryan Gaensler, his team found that the Milky Way is about 100,000 light years across and 12,000 ly thick (twice the previously accepted size) (speach given on the 211th meeting of the American Astronomical Society, Austin, TX, January 2008). Does this mean more mass than previously accepted - or just more thinly spread mass? (don't ask me :-). Given the app. distribution of star types: MK = MK-spectral class Rel.% = relative abundance in per cent of all known stars in the Milky Way galaxy. MK Rel.% O 0,00002 ( 1 in 5,000,000) B 0,01 A 1 F 3 G 9 K 14 M 73-78 about 45E9 Solar masses of this matter make up some 17 - 18E9 F5-K9 stars and about 130E9 M-dwarfs. (John): In that case ET will have to beam signals for millions of years at not just millions, but possibly billions of planets. The short answer: Yes. The long one: In my posting 21 May 2008 12:53:51 UTC, I guesstimated as follows: 1. Minimum assumption: 1.1. # of stars: F5-9V: 1.5% + GxV: 9% + K0-5V: 7% = 17.5% af 100E9 = 17.5E9 stars 1.2. at least 1/100 of these do have planets where life does exist, at least at a level where it was on Earth 4E6 years ago (oxygen etc.). 1.3. ET can see 40% of the planets => # of planets: 7E6 2. Maximum assumption: 2.1. at most 1/5 of these do have planets where life can exist. 2.2. at most 1/50 of these do have planets where life does exist, at least at a level where it was on Earth 4E6 years ago (oxygen etc.). 2.3. ET can see 60% of the planets. => # of planets: 60E6 Assuming that planets formed in orbits around M-dwarfs can support life, then adding all their planets, we shall (probably) end up in the billions (E9). (Matt:) The question to ask is, why they would broadcast at all? Even if they were sure we were here? In a previous posting, I did suggest 4 answers: 1. The very bad news: ETs know everyting about us, and don't like what they see. 2. The bad news: We are home alone. 3. The good news: ETs are around, they have noticed us, but presently prefer to just study us from afar. 4. The very good news: ETs have noticed us and they are doing their best to establish contact - only we are too darn primitive to understand their means of communication. Now here is answer 5 - the answer you don't want to read or hear, so if you want to sleep quietly and avoid repeated ET-nightmares for the next decade or more, I suggest that you skip #5 ::-)) 5. The really scary news: ET are like us (not in appearance, but psychologically). Like Homo Sapiens Warlordia they not only share the English gentleman's passion for bloodshed and slaughter, they are bullies too, i.e. they want to make sure that their opponent is the underdog before they engage in a fight. In that case they are studying us and all the while they are fine-tuning their weaponry. I wish the ETs - the lazy bastards - would get in touch with us, so we can stop guesstimating about these subjects and get it straight ::-))) . |
