Czechia through foreign eyes: you may check a fun essay Czech Republic – Where No One Gives a Fúçk by Klotild von SchweinhundsheimThe discovery of gravitational waves by the two U.S. LIGO detectors has energized the fans of this concept in many other countries.
As LIGO.org noticed,
LIGO India should be a collaborative project of 3 Indian institutes as well as Caltech and MIT so things shouldn't suffer from the shortage of expertise and high-tech know-how.
India should launch it before 2025. Why can't they clone the gadgets next week and run it in March 2016?
However, India isn't the only country with more than one billion people. With some so far unofficial backing by the Chinese government,
I am afraid that it is a big IF, however.
Just to be sure, in the Chinese philosophy, Taiji is the cosmological "Supreme Ultimate", a nerdy cousin of Jesus Christ symbolized by the Yin-Yang logo. (Yin and Yang are claimed to be opposite to each other but both Yin and Yang are excellent physicists.)
To make things confusing, taiji is also a Chinese martial art that is symbolized by a very similar yin-yang symbol, but one with the extra disk in the center that refers to stillness.
In July 2015, Sun Yat-sen University proposed another gravitational wave satellite project called TianQin which is hoped to be launched between 2025 and 2030. Two eLISAs per one China is probably too much to ask but it would be exciting if China succeeded at least with one of them and well before the Europeans succeed with eLISA (2034?).
The third Chinese project is planned for the town of Ali in Tibet. It's supposed to be a land-based detector of gravitational waves but the information seems confusing enough so that one can't know whether it's something like LIGO or something like BICEP/KeckArray. ;-) If you know more or if you have something interesting to say about these things, don't hesitate to do so.
Unlike the Indian LIGO, the Chinese projects haven't received any official endorsement from the political leaders.
Don't forget that Virgo, a 3/4-size sibling of LIGO, should start its advanced operations in Italy momentarily. Germany possesses GEO600, a much tinier (2x 600 meter) L-shaped detector, too.
