A New Way to Search for Alien Life

What would modern life be without lasers ? They entertain our cats , mould our corneas , destroy our missile , and distract from the terrible euphony at vitamin B complex - tier rock concerts . Now they could assist us find aliens .

The problem with looking for stranger , other than vexing probe and anxiety about head size , is equilibrize the depth and breadth of the hunt through the Nox sky for foretoken of life . Any switch in focus means a corresponding duty period in range of a function , and it ’s ruffianly to find a balance between the two .

A upright way to understand this is by ideate yourself on a cliff overlooking an sea . you may gaze out over the water , but you wo n’t be able to see much detail . Unless what you ’re looking for is giving , you ’re going to lose it . If you face through a pair of field glasses , you ’ll be able to see the details up close , but the majesty of the boundless sea will be lost on you . If the Loch Ness Monster pops up one column inch to the left of your champaign of direction , you wo n’t see a thing .

So what ’s the cheat , when it follow to astronomy ? What would allow us to see any source of communication over a broad range of space ? Let ’s put it this path . Most mass today ca n’t tell Vega from Polaris , but they ’re able to evidence Vega from an airliner bearing to Miami . Motion and change stands out .

This is where the lasers get in . There are lasers , now , that can bring forth lustrous light than the sun , and can move faster . woefully , they are n’t being used to space - write something cool in the promise that aliens can register it and be impressed . They ’re in reality not being used much at all . Our new strategy is to set up a detector that takes in blanket range of the sky in hope that some other planet has been suckered into pay for an unbelievably hefty optical maser , only to beam out subject matter into blank space in the Bob Hope that some other civilization might see them . The ball is in your court , Gliese 581 d. Do n’t keep us expect .
