The team then monitored these ticks using two different techniques; one measured extremely small electric currents, while the other used radio waves to detect subtle changes in the system.

LIDAR, unlike passive sensors, sends out its own light signals, working similarly to radar but with lasers instead of radio waves.

For the first time, researchers at Tel Aviv University have predicted what might be discovered by detecting radio waves that originated in the early Universe.

This unusual discovery revealed powerful and rapidly changing radio waves, showing that supermassive black holes can exist and stay active far beyond galactic centers.

Unlike visible light, radio waves from hot gasses are not blocked that easily by cosmic dust.
