Scientists want to camouflage Earth in order to hide it from Hostile Aliens


Some scientists believe that our planet is in danger of aliens that are hostile towards our population. In order to a save our planet from such beings, they want to camouflage Earth so the hostile aliens won’t be able to locate it.

Two astronomers have proposed that beaming controlled laser emissions could literally create an invisibility cloak around Earth, in order to help disguise the faint dimming of light produced by our planet every time it passes in front of the sun.

According to experts, Intelligent Alien civilizations might be looking for Earth  the same way we search for Alien Worlds: by looking for dips in our Suns light. This is why, they propose beaming a laser into the sky, in order to cloak this change in light. This ‘new’ system could effectively hide our planet from extraterrestrial telescopes, pointed at our planet. The method used in order to search for Alien worlds is based on light anomalies created by planets as they pass in front of their host star. Using this technique, NASA Kepler space telescope has discovered over 1000 new planets among them several which are believed to be extremely similar to Earth, located in the so-called habitable zone of their host star where temperatures are ideal for liquid water to exist.

However, it’s very likely that advanced alien civilizations inhabiting other parts of the cosmos might have adopted similar techniques in order to hide their worlds from possible predators.

Professor David Kipping and his student Alex Teachey from Columbia University in New York believe that ‘alien astronomers’ might be using similar techniques as we do, in order to spot habitable zones around distant stars. Some of these aliens might not be as benevolent as we would want them to be, this is why it would be a great idea to hide our planet from prying ‘alien’ eyes.

The two researchers believe we can effectively hide our planet by masking the dip it creates while passing in front of our star. This can be achieved by sending a continuous 30MW laser blast for 10 hours each year.

In the past, numerous scientists have warned about sending radio signals into outer space since it could attract hostile aliens that would be technologically hostile aliens that would be technologically superior than we are. Professor Stephen Hawking warned about Aliens last year in an interview with El Pais: “ If aliens visit us, the outcome could be much like when Columbus landed in America, which didn’t turn out well for the Native Americans. Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they can reach. To my mathematical brain, the numbers alone make thinking about aliens perfectly rational. The real challenge is to work out what aliens might actually be like.” Hawking speculated.

According to a statement from Dr. Kaku, who is an advisor on the Discovery channel’s Curiosity series, the human race wouldn’t stand a chance if Aliens came to Earth and attacked us. Aliens which could be over a million years ahead of our technology could wipe out mankind in seconds if they were to invade our tiny little planet.

This is why Professor David Kipping and Alex Teachey have proposed sending a continuous 30MW laser blast for 10 hours each year in order to hide our planet.

In their study, the duo wrote: „We suggest that advanced civilizations could cloak their presence, or deliberately broadcast it, through controlled laser emission. Such emission could distort the apparent shape of their transit light curves with relatively little energy, due to the collimated beam and relatively infrequent nature of transits. We estimate that humanity could cloak the Earth from Kepler-like broadband surveys using an optical monochromatic laser array emitting a peak power of about 30 MW for roughly 10 hours per year.

A chromatic cloak, effective at all wavelengths, is more challenging requiring a large array of tunable lasers with a total power of approximately 250 MW. Alternatively, a civilization could cloak only the atmospheric signatures associated with biological activity on their world, such as oxygen, which is achievable with a peak laser power of just around 160 kW per transit. Finally, we suggest that the time of transit for optical SETI is analogous to the water-hole in radio SETI, providing a clear window in which observers may expect to communicate. Accordingly, we propose that a civilization may deliberately broadcast their technological capabilities by distorting their transit to an artificial shape, which serves as both a SETI beacon and a medium for data transmission. Such signatures could be readily searched in the archival data of transit surveys.“

‘To another civilization, this should make the Earth appear as if life never took hold on our world,’ said Mr. Teachey.

The proposal created by Professor David Kipping and Alex Teachey are published in the journal Monthly Notices of the Royal Astronomical Society.
