The writing of ten million scanned stars and abstraction
The writing about ten million scanned stars
When somebody scans ten million stars in 17 hours that might seem very impressive. But in our galaxy, Milky Way is 200 billion stars. Ten million scanned stars in 200 000 000 000 stars in a milky way might seem very impressive. And the time of scanning per star might be less impressive than we are thinking. The estimation of the number of stars in the Milky way is 200 billion, plus or minus 150 billion, but the calculations in this text are made by using the value 200 billion.
When we are seeing that the Australian scientists have scanned 10 million stars in 17 hours and there are no alien civilizations around them might seem very impressive. The SETI-researchers are calculated that there could be something like 36 intelligent civilizations in our entire galaxy, so don't panic.
The possibility that the radio telescope would find those predicted civilizations from our galaxy is about 200 billion stars is quite little. So ten million stars are quite a few even in that number, and the reality is that the Australians were not scanned only G2 type stars, which is not very common.

This research where the star cluster of Vela scanned in numbers
Used time in hours 17 h
In minutes 17*60=1020 min
In seconds 1020*60=61200 sec
Used time per star 61200/10 000 000= 0.00612 sec/star
10 000 000/200 000 000 000*100=0.005% of the stars of the milky way have been scanned during this research.
36/200 0000 0000 0000=1,3e-10 is the possibility that the radio telescope would turn to the star, which has intelligent and technically advanced civilizations around them.
And this is one of the most optimistic estimations in the world. The time 17 hours mean 1020 (17*60=1020) minutes and 61200 (1060*60) seconds. So the researchers used 61200/ 10000000= 0.00612 sec per star, which means long term research.

Writing about abstraction
The abstract wallpaper "Face" is following the surrealist style of Salvador Dalí and there is one thing, that makes it interesting. The thing is that this kind of face is hanging on the wall. There is one interesting symbol in that painting, and that is that the face can be only the small part of the entirety.
So even if we are seeing the big thing, that thing can be only the part of the bigger entirety. Or there can be nothing behind it. That means that the big thing might be the hollow thing, where is nothing inside it. The big things are many times covering something, what might mean nothing, or they might mean many other things.
This is the idea of abstract art. The solution or image is not given as the form of a complete image. Brains of the watcher must just fill the thing, what the image portrays, and make the own decisions for that kind of paintings. Making my own decisions is one of the most important things in the real life, and the thing is that people should not depress if they are finding some other decision than others. In the world of art and philosophy is no right answers, there are only questions that are taking us to different roads.
