Radio bursts 'may be powering alien ships'

Are aliens producing these bursts ? Image Credit: Casey Reed - Penn State University
A new paper has suggested that we may have already found evidence of intelligent extraterrestrials.
It's a phenomenon that has managed to defy explanation for years - powerful bursts of radio waves originating from far beyond our own galaxy that, despite lasting mere milliseconds, generate as much energy as the Sun does in an entire day.

Several possible explanations for these strange bursts have been put forward over the last few years, but now two researchers from the US have published a new paper detailing the possibility that this mysterious phenomenon may actually be evidence of an advanced alien civilization.

They began by determining whether it would be possible to create a radio transmitter large enough to create bursts that can be detected in other galaxies. A solar-powered transmitter covering a region twice the size of the Earth, they argued, should be enough to do the job.

Assuming that a sufficiently advanced alien civilization would have the resources to construct such a structure however, what exactly would it be used for ?

According to the researchers, the most likely answer is that these powerful bursts could be used to propel payloads of up to a million tons from one star system to another using light sails.

"Science isn't a matter of belief, it's a matter of evidence," said co-author Avi Loeb of the Harvard-Smithsonian Center for Astrophysics. "Deciding what's likely ahead of time limits the possibilities."

"It's worth putting ideas out there and letting the data be the judge."

If I have read the article correctly, the radio beamisused to push against a "sail" on the alien spacecraft. If we are detecting the radio beam, then that is because it ispointing in our direction. And that means the beammust be propelling an alien spacecraft in our direction ... As an aside, I would have thought shorter wavelength photons would be used as they are more energetic and less prone to dispersal than radio waves. When the aliens arrive I will point that out to them. Here's another thought. Perhaps encoded within the radio beam are instructions to show us how to make a similar r... [More]

They won't come here. The radio bursts are coming from galaxies billions of light years away, meaning that it would take the aliens tens or hundreds of billions of years to reach us using light sails. They couldtravel to nearby stars in their own galaxy but nofurther. The aliens who sent the bursts have been dead for billions of years, and their star and planet havein many cases already died, when we detect the burst.

Time and distance make contact with alien civilizations highly unlikely.

Only where time and distance are relevant. The deserts and oceans were an obstacle to early man but they managed it tens of thousands of years ago. Time and distance are somewhat different to a humanand say a fly? Yes if a certain alienwashuman size or microscopic but they could be mahoosive! A bedbugwould take a lifetime to walk what we could walk in an hour. The Aliensspacecraft could be the size of the earth with an engine the size of the Moon.. Bigger, more power, faster.. Like comparing The Wright brothers first planeto Saturn 5.Evolution. That only took less than 100 years. They m... [More]

I don't think you read it correctly. It is a "fast" radio burst because they say it sweeps past us because of relative motion. My problem with all this is that if we are seeing these massively energetic flashes, then MOST of that energy MUST be missing those giant Sails the paper assumed!!! Just throwing that out there...

Rather than this just being a veryinteresting theory....who knows.....maybe one day it mightbe proven as fact that there is an intelligent species of life out there (and possibly others) as far asthese mysteriousradio bursts are concerned. If anything... it's nice toimagine about the far reachingpossibilities.
