Fiber optics

Scientists have shown that the Earth is round for well over 2,000 years. Yet, flat-Earthers remain unconvinced. Earth aside, Scientists have just developed a technology where flat is a clear winner over round: optical fiber sensors.

Taara has been developing tech to deliver connectivity across communities without underground cables over the last few years. For its latest trick, the Google spinoff is now providing fast internet access across cities using invisible beams of light.

For years, Alphabet's Taara has been delivering internet connectivity in remote areas with traffic-light-sized transmitters that communicate over long distances using beams of light. The tech has now been reduced down to a fingernail-sized chip.
