More Mysterious Radio Bursts Were Detected Radiating From Space

Another series of mysterious “fast radio bursts” (FRBs) has been detected by a new telescope in Canada, emanating from somewhere deep in the cosmos. The last detection of FRBs came last year, picked up by Breakthrough Listen, a project focused on detecting signs of intelligent extraterrestrial life.

FRBs are a series of incredibly short, powerful radio emissions in millisecond lengths, coming form an unknown source, lightyears away. Signals were detected last year, named FRB 121102, and were the first repeating radio bursts ever discovered, believed to be emitting from a distant neutron star — the highly dense core of a collapsed star.

 

The source of the latest signals could be a number of things, including an exploding black hole, magnetar, a spinning pulsar known as a blitzar, or the most exciting prospect; a highly advanced extraterrestrial race.

The frequency of these signals, named FRB 180725A, are the first of their kind to be detected below 700 mHz. The FRBs earlier this year were above 800 mHz, with scientists calculating their source to be some 3 billion lightyears away. The source would have emanated the same amount of power in each burst as our sun does in an entire day.

If these mysterious waves are coming from an extraterrestrial civilization, their setup would be equivalent to two Earth-sized generators, and would likely exist as a power source for spacecraft, rather than simply sending signals into the universe to make their presence known.

The signals were detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) in British Columbia, a telescope that has been operating for under a year, with the primary goal of detecting FRBs. The telescope constantly scans 1,024 individual points in the sky 24/7, at 16,000 different frequencies, 1000 times per second; talk about an advanced piece of technology.

The first FRBs were discovered about a decade ago, making them one of the newest cosmological phenomena monitored by astrophysicists. Only a few dozen of these radio bursts have been detected since their initial discovery and scientists still consider the extraterrestrial explanation plausible.

Now that the CHIME telescope is solely focused on the signals, it may only be a matter of time until evidence of an intelligent extraterrestrial source are discovered. If they are from an advanced civilization, let’s just hope it still exists, considering these signals would have been sent millions or even billions of years ago.

Is This a Solution to the Fermi Paradox?

Is This a Solution to the Fermi Paradox?

A new theory has been devised on why aliens have never visited Earth, that we know of, as a possible resolution to the Fermi paradox.

Many who are curious about the existence of ETs have heard about the “Fermi paradox,” named after famous astrophysicist Enrico Fermi.

The story goes that in a lunchtime conversation with other astrophysicists who reasoned that, given the vast size and age of the universe it stands to reason, there must be other intelligent life out there, to which Fermi asked, “where is everybody?”

For decades people have tried to answer that question if there are so many possible ET civilizations, where are they? Now, astrobiologists Michael Wong, of the Carnegie Institution for Science, and Stuart Bartlett, of the California Institute of Technology offer their hypothesis, and it’s a bit dark. 

Using studies of the growth of cities on Earth, they argue that civilizations grow infinitely but in a finite time. This infinite growth of population and overuse of energy will eventually lead to the death of the civilization or possibly saving themselves.

“We propose a new resolution to the Fermi paradox: civilizations either collapse from burnout or redirect themselves to prioritizing homeostasis, a state where cosmic expansion is no longer a goal, making them difficult to detect remotely.”
