To find the other living creatures in this universe is always remain a difficult task for scientist. A team of theorists studying ‘fast radio bursts’ found that these signals, which have confused scientists for nearly a decade, could be coming from faraway alien transmitters powering interplanetary probes. A new study has claimed that these mysterious signals coming from other galaxies could help to explore new wonders, billions of light years away from earth.
The researchers determined that trickle from the transmitters could effect in transitory explosions detected here on Earth, as the sail of the probe, the host planet, its star, and the galaxy all move relative to our planet.
According to the Harvard-Smithsonian Center for Astrophysics, this explanation is within the demesne of probability based on the laws of physics. But this work, that has been done so far, is only hypothetical. These type of advance technology is currently beyond the capabilities of human being but we cannot say that it’s something that lies in the category of impossible.
For the first time in 2007 these Fast radio bursts (FRBs) were ‘heard’ by radio telescopes and are thought to originate from distant galaxies. But, scientists are not able to provide the confirm source yet, and many have suggested they could be a sign of alien life.
Avi Loeb of the Harvard-Smithsonian Center for Astrophysics said: “Fast radio bursts are exceedingly bright given their short duration and origin at great distances, and we haven’t identified a possible natural source with any confidence, an artificial origin is worth contemplating and checking”.
Researchers examined the possibility of building a radio transmitter strong enough to be observed from Earth, a new study has been published in the Astrophysical Journal Letters. Solar-powered transmitter and water-cooling system are the methods to be used as, the researchers found that a solar-powered transmitter using sunlight cast on an area twice the size of Earth could generate enough energy to be 'seen' by far away viewers. And, a water-cooling system would allow a device of this size to withstand the extreme heat.
The researchers claim that the most probable use for this marvelous amount of power would be to drive interstellar light sails. This type of system would be powerful enough to drive a payload of a million tons about 20 times the largest cruise ships on Earth.
The co-author Manasvi Lingam, of Harvard University said: “That’s big enough to carry living passengers across interstellar or even intergalactic distances”.
The light sail would rely on a steady beam from the transmitter. While this would always be pointed at the sail, observers on Earth would see it as a brief flash. This is because the sail, its host planet, its star, and the galaxy would all be moving relative to us. This would cause the beam to arch across the sky, only pointing at Earth for a moment.
Loeb says: “Science isn’t a matter of belief, it’s a matter of evidence, deciding what’s likely ahead of time limits the possibilities. It’s worth putting ideas out there and letting the data be the judge”.
As scientists work to understand the origin of fast radio bursts, with many offering possible explanations both natural and artificial, the researchers note that the more data will reveal the truth soon.
