Earth's largest lasers can be used for more than astronomy, like using it to detecting alien ships, as they create reactions every time they manipulate space-time, causing ripples. Some advanced civilizations might have warp drives that shorten from point to point in the space-time continuum.

Earth's Largest Laser To Probe Space for Alien Ships 

Rippling space-time could, according to scientists, be the presence of huge starships as they exit, which is the reaction the world's largest gravitational wave observatory is capable of tracking, reported Live Science.

A gravitational wave is any mass moving in space; objects like planets, neutron stars, and even a singularity or Black hole create powerful gravitational waves like huge ripples in a still pond.

In 2015, these ripples of space-time were seen the first instance. But scientists are learning to identify them better in the cosmos.

These new calculations were published last Dec.5 on arXiv, showing that the U.S.-based Laser Interferometer Gravitational-Wave Observatory (LIGO) can find these ripples. It is not possible that massive extra-terrestrials moving past light speed or warp engines are sure to create this turbulence in the fabric space itself.

The LIGO detector positions gravitational waves from the relatively small deformations they create in space-time just like they cross through all of it. They are composed of two dual intersecting L-shaped detectors with 2.48-mile-long (4 kilometers) arms and two identical laser beams in the interior.

Such an experiment is to detect a ripple in space-time that slams into the earth, laser light in one will get compressed as the other expands.

It will be a relative change in the direction of the lasers intersecting at the detection. But it is difficult to detect a rumple in the fabric of time and space; even the biggest gravitational waves are too small. The LIGO is very sensitive and needs constant adjustment, citing Viva.

Experiment To Detect Ripples in Space 

Determining how far this responsiveness could have been extended, scientists found the arithmetic operations of the smallest object that would produce perceptible gravity waves on earth.

These ripples in the fabric of space are massive, which allows LIGO to detect an alien starship almost the size of Jupiter, as it travels to almost about a fraction of light speed and is estimated close to 326,000 light-years from earth.

Researchers are still determining if it is technologically feasible to construct a planet-sized starship or travel at the speed of light. Even if they keep hoping that more sensitive gravitational wave (GW) detectors will be incorporated, such as the European Space Agency's 2037 Laser Interferometer Space Antenna, a ship will appear more accurate.

Scientists think that advanced warp drives in an alien starship would likely create ripples and waves that cannot be missed. It, according to researchers, gives a hint to creating such groundbreaking technology.

The shape of the GW is all about the direction of the object said in the paper. If a burst signal is recorded, then how it got there and the shape of the gravity wave signal is decoded.

Earth's largest lasers, like LIGO, could be a microscope to spot giant alien ships passing through space-time.
