Title: Gravitational Waves from Mirror World

Merger Rates of binaries observed by LIGO-VIRGO gravitational wave detectors exceed numbers predicted by majority of models, also none of the events (except one) was accompanied by another type of radiation. We suggest that major these signals emerged from Mirror World where:

i) Number of binary systems is higher, since Mirror Matter is a candidate of Dark Matter having higher density

ii) Binary Merger Rate is amplified, since mirror world is considered to be colder and star formation there started earlier

iii) Non-detection of electro-magnetic radiation is natural, because mirror particles do not interact with ordinary particles

We predict about 10xlarger Merger Rates for LIGO-VIRGO systems and only 1 of 10 Binary Neutron Stars event may have electro-magnetic counterpart.
