The invisible and unseen has always fascinated us humans.
Mapping both literal and metaphorical has always been about our quest for knowing.
As an astrophysicist, my research work involves mapping dark matter, the elusive substance that accounts for about a quarter of our universe. This is, though, not the first attempt to map the unknown. The deep fascination with the mysterious, and the impulse to seek and locate ourselves in the cosmic context, seems to be imprinted in our DNA and psyches.
