....Because, the Observable Universe contains ten times more galaxies than previously thought!! WOW, can we believe this? And in the narrative they say "AT LEAST TEN TIMES AS MANY GALAXIES AS PREVIOUSLY THOUGHT"!~!
While the thinking was for the existence of 100 billion to 200 billion galaxies, those numbers now all of the sudden are 1 TRILLION to 2 TRILLION galaxies at the least............just in the "observable Universe"!
Hello?? Is anybody home way out there?? What a remarkable place of which we are a part. Maybe one of these days we wil actually start to learn what is the real reality of this tremendous and seemingly infinite existence!!
Hubble Space Telescope
13 October 2016
Astronomers using data from the NASA/ESA Hubble Space Telescopes and other telescopes have performed an accurate census of the number of galaxies in the Universe. The group came to the surprising conclusion that there are at least 10 times as many galaxies in the observable Universe as previously thought. The results have clear implications for our understanding of galaxy formation, and also help solve an ancient astronomical paradox — why is the sky dark at night?
One of the most fundamental questions in astronomy is that of just how many galaxies the Universe contains. The Hubble Deep Field images, captured in the mid 1990s, gave the first real insight into this. Myriad faint galaxies were revealed, and it was estimated that the observable Universe contains between 100 to 200 billion galaxies [1]. Now, an international team, led by Christopher Conselice from the University of Nottingham, UK, have shown that this figure is at least ten times too low.
Conselice and his team reached this conclusion using deep space images from Hubble, data from his team's previous work, and other published data [2]. They painstakingly converted the images into 3D, in order to make accurate measurements of the number of galaxies at different times in the Universe's history. In addition, they used new mathematical models which allowed them to infer the existence of galaxies which the current generation of telescopes cannot observe. This led to the surprising realisation that in order for the numbers to add up, some 90% of the galaxies in the observable Universe are actually too faint and too far away to be seen — yet.
"It boggles the mind that over 90% of the galaxies in the Universe have yet to be studied. Who knows what interesting properties we will find when we observe these galaxies with the next generation of telescopes," explains Christopher Conselice about the far-reaching implications of the new results.

Well there you go -
The more we learn the more we realize how much we still have left to learn!
Nice find Rdunk! 8)

Where are these tens of thousand of galaxies in the Book?
::)
So why are we not seeing more aliens? Simply because our entire time of existance on this rock is a mere blink of an eye in the universe.
Tomorrow we could get wiped out by a relatively small rock from space and all we are, have been or ever will be would vanish in a flash... and the universe would never know we were here
The planet is moving through space in 7 different directions at a toal speed close to two MILLION miles per hour.
Any planet that may have life is doing the same thing..
So today NASA gets a single blip... a WOW signal... By the time they analyse where it came from, the source, and the listener have moved several million miles in unknown directions.
Trying to pinpoint the source of that signal becomes near impossible so we won't catch it again. That blip only passes us once on its way out and is gone forever.
Astronomers tell us this movement doesn't really matter. This might be true of a CONTINUOUS beacon like signal. You can sweep the general area and maybe catch it again. But single short transmissions? Nope not gonna happen. Any radio operator can vouch for that
So SETI should be looking for ship to ship LOCAL signals, considering that everyone believes the Aliens are visiting us daily in droves :P Surely they communicate between ships and the mothership?
Hmmmmm
Yes Z, a BIG subject we have here, and even bigger when we brig in the alien possibility/probability!
You are right! Of course!! Finding signals up to umpteen billions of light years out is quite meaningless..........within our current understanding of the "known" Universe. For us, there is no way of communicating in realtime to even the shortest distances outside our "Solar System". But, as you imply, we are of an "infantile race", and comparatively there is nothing we can do about that either. If we ever find an alien race, it will probably happen pretty much locally.
Of course, finding "evidence" of aliens is very much past tense.......for some of us! But actually finding live ones.......they will probably find us!! ;)

Yes because that signal left the source over a billion years ago and by now the entire system may not even exist anymore
Quotewithin our current understanding of the "known" Universe. For us, there is no way of communicating in realtime to even the shortest distances outside our "Solar System".
Quite true. people tend to forget that our own radio signals only started about 100 years ago and the early signals had very limited range. So figure effectively about 60 years ago before we find a signal strength powerful enough to carry MODULATED information waves on the carrier signal that could go beyond the solar system.
That means that only Aliens living within 60 light years could even hear our signal above the back ground noise and we have found no signs of life in that limited distance. And anyone living at 60 light years away is just now getting our WWII reports and the Roswell shooting down of a Saucer live broadcast :P
A good example is the message we sent to Gliess 581 system That system is only 20.5 light years away but our message will still take another 14 years to get there Well 13 years:129 days:18 hours :58 minutes:58 seconds at time of this writing :P
The top message? "Hello Gliese 581d inhabitant. Can you help us humans travel through space and become smart like you. Please do not eat us we are a friendly race.

So you have finally accepted that those called gods in various books are indeed ancient aliens? :P
Zorgon Quote, "So you have finally accepted that those called gods in various books are indeed ancient aliens? :P"
Well not quite, of course! Considering that I believe there is only one God, with 3 persons, and this God made all that exists, my thinking is that He certainly is not an "alien" to his own stuff, not here nor anywhere. :)
As far as the ancients go.......who knows about their reality.........I certainly do not! :) There is so much ancient stuff around the world that is known, and still being discovered. But, it seems that so often, true source and historical purpose remains hidden - as if that such too could be by plan!! On the other hand, I would not be surprised if it were discovered that those ancients with advanced inteligence were aliens of some sort. 8)

Possible extraterrestrial intelligence evidence - Peculiar periodic spectral modulations 234 solar type stars out of 2.5 million starsQuoteThe Sloan Digital Sky Survey has analyzed 2.5 million stars and is seeing very short light pulses along with normal light spectrums from their stars. The brief light pulses seen at 234 out of 2.5 million stars is consistent with a high power laser (which our current technology is capable of making) and shining in the direction of other stars. This method of signaling and detection was written in a prior 2012 research paper.
A Fourier transform analysis of 2.5 million spectra in the Sloan Digital Sky Survey was carried out to detect periodic spectral modulations. Signals having the same period were found in only 234 stars overwhelmingly in the F2 to K1 spectral range. The signals cannot be caused by instrumental or data analysis effects because they are present in only a very small fraction of stars within a narrow spectral range and because signal to noise ratio considerations predict that the signal should mostly be detected in the brightest objects, while this is not the case. We consider several possibilities, such as rotational transitions in molecules, rapid pulsations, Fourier transform of spectral lines and signals generated by Extraterrestrial Intelligence (ETI). They cannot be generated by molecules or rapid pulsations. It is highly unlikely that they come from the Fourier transform of spectral lines because too many strong lines located at nearly periodic frequencies are needed. Finally we consider the possibility, predicted in a previous published paper, that the signals are caused by light pulses generated by Extraterrestrial Intelligence to makes us aware of their existence. We find that the detected signals have exactly the shape of an ETI signal predicted in the previous publication and are therefore in agreement with this hypothesis. The fact that they are only found in a very small fraction of stars within a narrow spectral range centered near the spectral type of the sun is also in agreement with the ETI hypothesis. However, at this stage, this hypothesis needs to be confirmed with further work. Although unlikely, there is also a possibility that the signals are due to highly peculiar chemical compositions in a small fraction of galactic halo stars.
The objects listed in Tables 1 and 2 should also be observed with large telescopes to obtain spectra with high resolutions and high signal to noise ratios that would allow studying the signals in greater details to definitely confirm that they are not data reduction or instrumental effects.
They considered the possibility that the signals are caused by intensity pulses generated by Extraterrestrial Intelligence (ETI), as suggested by Borra (2012), to make us aware of their existence. The shape of the detected signals has exactly the shape predicted by Borra (2012). The ETI hypothesis is strengthened by the fact that the signals are found in stars having spectral types within a narrow spectral range centered near the G2 spectral type of the sun. Intuitively, we would expect stars having a spectral type similar to the sun to be more likely to have planets capable of having ETI. This is a complex and highly speculative issue (see Lammer et al. 2009) and we shall not delve on it. Let us however note that all of the active optical SETI observational projects listed in Tarter (2001) search for signals in Solar-type stars. Reines and Marcy (2002) and Howard et al. (2004) searched for signals generated by lasers in nearby solar stars. In particular, let us note that Howard et al. (2004) searched for nanosecond optical pulses from nearby solar stars
The ETI hypothesis requires that all different ETI transmitters choose to broadcast with the same time separation of pulses and one may wonder why they do so. This is a highly speculative issue that may have several explanations. A possible explanation that makes sense is that all ETI use the same time separation to make it clear that the pulses all come from ETI.

Good old Nottingham (my turf) working to show us all that the Universe is just too full of possibilities for us to not find life elsewhere.... Eventually.

only 234? :P
I do see THIS... "The ETI hypothesis requires that all different ETI transmitters choose to broadcast with the same time separation of pulses and one may wonder why they do so. This is a highly speculative issue that may have several explanations. A possible explanation that makes sense is that all ETI use the same time separation to make it clear that the pulses all come from ETI."
The last time they found a weird signal, they discovered pulsars :P
I do like Optical Seti though They search for lasers not radio waves. Makes more sense
But considering the eons of time and the distances between stars, finding a civilization like us in all that mess is like finding a needle in a haystack... unless they are within a few hundred light years, their entire civilization may already be gone before we get that signal
Or entire existance is between 10,000 and 100,000 years depending on who you believe :P but our technology is only a few hundred years and we are on the edge of making ourselves extinct already. We are a mere blip on the universe's timeline. The odds of meeting ET are pretty slim :P They are certainly not here in droves :P

Unless civilisations are relatively common... But the distance is an issue by the methods we currently assume they will use to contact us... We know frig all

I don't agree with that. We could be about to colonise space and extend our civilisation by a long time. We can't be sure which is why it is that astrobiology and similar are such exciting fields, at least for me.
Stop being such an old pessimist! :)

I once believed that. I wanted to be an Astronaut... :P I was an Apollo groupie. I was SURE I would be flying in space by now I even have a ticket for the first flight to the moon on Pan American... (it's framed :P) and one from Air Canada.
But since then it looks like the space program fizzled and died... we can't even get rockets up without exploding them frequently these days. people blame the accidents on ET... REALLY? How about just human incompetance? :P
So may I am a pessimist now Thanks NASA :P
I hope Hu-mons can wake up and get their sh!t together... but I see now that it will never happen in my lifetime anymore
Besides... I hear a big asteroid is on the way to make us extinct like the Dinosaurs (and they were around for hundreds of millions of years :P ) haven't you been watching the internet? We are all doomed because those space rocks are coming!!!

Been hearing that for some time now... If it is going to happen there is going to be a plan. IMO.
QuoteWell good luck with that :P
If they would give me a few million to build the right team that would be lovely. I suspect NASA want to be the first so we need a benefactor. The Nelson Rockefeller institute of Astrobiology has a ring to it! ;D
Jusr MAYBE.........the biggest problem we must overcome in our finding ET, is to get over our "elementary" scientific thinking of the space between two places in the Universe as being "distance"! Yes, everything we know tells us it is simply "distance that must be traveled" to get from one place in space to another. Distance.......a severe spatial restriction that must be overcome, if we are to become truly explorers of this Universe!
What if we quit thinking of linear space as distance, but rather think of any and all of the Universe as being a complex compilation of "specific ethereal defined points"?? Then we move to discover the technology that with the input of defined points, we jump (change places) instantly from one point to the other........way better than worm holes or warp drives. That would be like thinking, I don't want to be here anymore, I want to be over there, and then you are!! Except, my approach is that it would be done by technology!!
Why not? Space is basically a vacuum anyway isn't it? Could we use lightwaves for an instant coordinate "jump", either way. Or could we use dark energy or dark matter for an instant jump? Instant jump from one point to another might be an automated series of instant jumps, depending upon tech and capability.
However we do it, we must overcome the "distance/light years" thing"!! 8)

Well science fiction writers have been telling us that for decades :P and Quantum Physics is telling us that now. But we are still LOOKING for Et using radio and laser signals, both which travel at the speed of light, so a signal blip from a star 5 billion light years away is likely long gone in a super nova, taking it's planets with it :P
That is why I keep saying 'Anti Gravity" is Bullpoop and useless What we need is MORE gravity to warp the space, like putting a dot A and B on a paper, and simply folding space (the paper) so the two dots meet... then simply stepping over from A to B and then release the fold. let it snap back
But Anti Gravity, like UFO's keeps the masses distracted and on the wrong path
