Fast radio
bursts are possibly the most mysterious astronomical phenomenon of the new
century. Their study began just over a decade ago when in 2007 Duncan Lorimer
and his team stated the discovery of the first very powerful, but short (a few
milliseconds) radio burst that came “out of nowhere.”
That is,
as it was nearly half a century ago with cosmic gamma-ray bursts, the flare was
no longer detected in any range of the spectrum, and in addition, it was not probable
to precisely localize what it was associated with.
It took
nearly a decade before astronomers were able to confirm the cosmological origin
of fast radio bursts but now, we hear news about newly discovered signals
literally every month. The source of these FRBs remains unclear.
Older
theories proposed that they could either come from neutron stars or black
holes. In 2020, several researchers reached the conclusion that certain fast
radio bursts initiate from magnetars but this may not be the same for all such
signals.
Now, a
Chinese team of researchers has reported the most incredible find – three fast
radio bursts from the early periods of the Universe. The FRBs were revealed in
data from the Five-hundred-meter Aperture Spherical radio Telescope (FAST) and
have been verified to be at least several billion years old.
Based on
the data obtained by FAST from 2020 alone, researchers suggest that with more
focused observations, there may be more than 120,000 FRBS that we could
intercept every single day. Can you imagine what researchers could do with such
knowledge and what mysteries of the universe may be answered?

ET calling their friends in UFO's circling our atmosphere and hanging out at our nuke plants. "Hey, how's it going? Are humans any smarter yet? They ready for us?" Short answer: "No"...lol
