One day a small meteorite impact occurred somewhere over the Pacific Ocean, and moments later a mysterious green glow sweeps across the globe at an amazing speed.
All of a sudden everyone can hear voices and screams from somebody they didn't know, most would suffer from a severe mental breakdown but some managed to survive the agonizing ordeal. It was soon discovered that this is caused by a certain part of the brain somehow had gained the ability to send and pickup thoughts, the range is infinite and speed almost instantly.
It seems the "antenna" cannot be turned off or disrupted by any means, but it is proven that our brain can suppress and to a certain degree even mute out incoming thoughts at will! Soon meditation courses and gurus starts popping out of nowhere, businesses beginning to show sign of recovery all except telecom that are still left in the wreck as millions flock to terminate their lines.
I'm wondering is there any glimpse of hope for the telecommunications industry? This ability is active, passive, always on, so you can't pick a single or group of known targets to do private messaging or group chats!
