Could A ‘Laser Cloak’ Hide Earth From Evil Aliens?

A new paper from David Kipping, an astronomer at Columbia University believes it could.

In this paper David Kipping goes on to explain how a 22W laser could disrupt measurements of the Earth’s orbit around the sun, thus deceiving any potential harmful onlookers.

Kipping and his graduate student Alex Teachey, conclude that it would be remarkably easy to “wipe out” Earth’s signal, or at the least distort it. All you need to do is disrupt the “transit method” most commonly used to identify objects in orbit around stars. The transit method is how we identify most planets today, by looking for dips within the light signals of stars – when believed objects pass by.

“To make it look like the planet is not there at all, you’ve got to get rid of that dip. You’ve got to fill in the missing starlight,” Teachey tells in a video.

The Kepler telescope uses small dips in a star’s brightness to identify orbiting objects.

Planets can still be detected in other ways, such as the gravitational influence on a star – however the idea behind this technology is that it would act as a deterrent to arousing suspicion, thus hindering the possibility of conducting such gravitational experiments.

The idea of cloaking ourselves from aliens could work. However, it needs one specific caveat to make any sense – a universe in which we suspect extra terrestrial life exists, and peering into our daily lives. While that may be entirely true, it’s likely that this theory remains just a fun possibility for astronomers.
