What is the purpose of ‘evolved Laser Interferometer Space Antenna (eLISA)’ project?
(a) To detect neutrinos
(b) To detect gravitational waves
(c) To detect the effectiveness of missile defence system
(d) To study the effect of solar flares on our communication systems
Solution: (b) To detect gravitational waves
eLISA’s primary objective is the detection and examination of gravitational waves emitted by the super-massive black holes that reside in the centres of many galaxies. In addition, eLISA will measure the signals of thousands of compact binary star systems in the Milky Way.
