Mysterious radio waves can be a sign of aliens

Radio waves, the most mysterious signal in the universe, can be emitted from devices the size of a planet used to propel spacecraft.

Radio waves (Fast Radio Burst or FRB) are the most mysterious phenomenon ever known by humans in the universe. Earlier this year, astronomers first identified the location of FRB in a dwarf galaxy 3 billion light years from Earth, according to Popular Mechanic.

A radio wave is detected.

High-intensity electromagnetic flashes last only a few milliseconds, causing astronomers to be confused from the first discovery in 2007. The leading hypotheses suggest that FRB originates from unstable events, such as things. The substance is fired from the supermassive black hole, the explosion of supernovae has a high brightness, or is affected by the magnetic field of the magnetic star (magnetar) with surrounding matter.

But the team at the Harvard-Smithsonian Center for Astrophysics (CfA) hypothesizes that FRB is not a natural phenomenon, but comes from an extraterrestrial work , aimed at providing energy. for spaceships.

"If the radio waves are extremely bright, considering the short duration of existence and distance, we have not identified a natural source with similar capabilities. Artificial origin is a factor worth considering. ét, "Harvard University Avi Lob professor said.

Large-scale electromagnetic flashes last only a few milliseconds, causing astronomers to be confused from the first time they were discovered.

This hypothesis suggests that FRB emitted from the alien's enormous energy source, is used to propel cruise ships with light sails. A strong light beam can push the reflective surface in space, this is the basic principle of light sail technology.

Sailing the current light of humans using light sources from the Sun. But scientists are working on developing a global laser device system that can push the device at 20% of the speed of light. Light propulsion technology can take the probe satellite to Alpha Centauri, the closest star system to Earth, in about 20 years.

It is possible that an alien race is more developed than humans who have used light propulsion to operate a large size space shuttle. If an object twice the size of the Earth collects solar energy and converts it into a spacecraft, the radio waves can be identified from billions of light years away.

Signals from FRB are converted to audio.

Such an energy system could speed up the spacecraft weighing millions of tons."It is big enough to carry alive surviving interstellar passengers even between galaxies," said researcher Manasvi Lingam.

This is a hypothetical hypothesis. The true origin of FRB is still an unknown solution.
