For decades, we have been listening to the skies using radio telescopes – hoping to catch the faint chatter of alien signals.New Spanish attack sees five terrorists shot dead at beach resort
But we’ve heard nothing – and one of the reasons might be that we’re listening all wrong.
The scientists behind the Search for Extraterrestrial Intelligence (SETI) project are now aiming to look for the telltale ‘flashes’ of aliens communicating with lasers.
It’s a different approach to previous laser experiments – which assumed that ET would constantly be beaming signals towards us.
A new ‘Laser SETI’ detector, currently seeking funding via Indiegogo, could see these flashes.
The project page says, ‘Until now, SETI experiments (Search for Extraterrestrial Intelligence), whether listening for a radio transmitter or searching for a high-powered laser, have assumed that ET is on-the-air all the time, so that wherever the instrument is pointed, the signal will be there.
‘Laser SETI is the first experiment to circumvent this assumption.
‘Laser SETI could find a very short ping from anywhere on the night sky. Indeed, it could detect a laser flash as short as a millisecond or less; and one that might not repeat for days, weeks, or even longer. Or ever.’
