Wearing dark ball is the thing that the civilized ability of science and technology of Yuan Chao's mankind makes, it belongs to strictly speaking a kind of building that having the sources of energy to receive a function, but the scope of this kind of building is true too big, all structures that human place builds add up, also be not a patch on of this kind of building millions upon millions 1/0.
"Wearing dark ball " is astronomer Fuliman Daisen puts forward when 1960, those who point to is a diameter 200 million kilometer controls use wrap up star to extract thereby sidereal can man-made building, in attributing a kind of tentative plan giant man-made structure, he thinks this kind of structure is what advanced civilization develops in the universe is inevitable, because of civilization develops more, the sources of energy that its need is more, planetary form culture needs to use those who come from place planet all sorts of the sources of energy, and sidereal form culture must use the sources of energy that comes from star mainly, we know star is tremendous nuclear fusion plasma ball, the all the time is not releasing tremendous energy, so the huge wall that builds one side to draw sidereal energy in sidereal periphery, the solar energy that is like our place to use is received board same, the energy that comes from star so is OK be used by the reception with our constant in a steady stream, need not be anxious for the sources of energy again.
After wearing dark ball concept to be put forward, be deduced by sci-fi ceaselessly, home of a lot of sci-fi still designed Dai Sen ball to make plan, and astronomer people when searching the civilization outside the ground, also used this one tentative plan, use occultation luminosity change to observe whether to have Dai Sen ball, judge thereby whether to have civilization of tall substandard star, still never mention it, scientists still discovered a such celestial bodies really -- the star that number is KIC 8462852.
This star says the tower compares a star again, it is a F- model advocate foreword star, be located in Cygnus, be apart from us 1480 light-year, the diameter is 0.5 times bigger than the sun the left and right sides, quality is 1.43 times of the sun about, astronomical observation discovers its brightness can appear to fluctuate unusually, and have regularity, most paled substantially 22% , astronomer is passed " approach star law " discover it is in respectively in March 2011, in Feburary 2013, in April 2015 and appeared in May 2017 luminosity drops phenomenon.
Of 22% fall it is quite big, can hold back a tower to compare a star without the planet the light of 22% , even if is Jupiter so large celestial body discharges, hold back so much impossibly also, so astronomer people thinking is the Dai Sen in fokelore probably the ray that the ball stopped this star just appeared this kind of phenomenon, because this also has not little person,think to be put probably in the tower to compare astral civilization.
If the tower compares luminosity abnormality of the star,the phenomenon is the word that Dai Sen ball causes really, so OK and affirmative is tower comparing there is outclass near the star the advanced civilization of our mankind civilization, is this blessing to our mankind be disaster? This is a problem that cannot say clear, so high culture should be to be able to span the distance of 1500 light-year comes to tellurian, but we still cannot walk out of the earth however, if their believe in is jungly law, so our mankind but dangerous.
If not be Dai Sen ball, still have other possibility so? Also be some, the writer thinks or be this planet periphery one day having a tremendous dust link, the appearance of this dust annulus is inhomogenous, perhaps run orbit territory bigger, because this ability appeared of regularity hold back sidereal light phenomenon. Also be tremendous likely additionally broom asterism bypasses star holds back the light to bring about regularly.
