They're scanning time? No. They're scanning buildings as a way of taking people back in time. Sort of. Basically, the series uses modern technology to explore ancient sites, trying to solve mysteries and make the structures and people who built them more relatable for the people of today.
Using a mobile laser scanner, which bounces pulses of light off objects to map them, host Dallas Campbell, structural engineer Steve Burrows and their team use their fancy gadgets and meet with local archaeological and history experts to do some high-tech, in-depth exploring:
Jerusalem: The Temple Mount is examined to see how King Herod's builders managed to create a structure that survived centuries of war and earthquakes.
