For years, a question that human beings often ask about the universe is: “Are we alone here?” In January, 2019, the discovery of new fast radio bursts (FRBs,快速射电暴) from deep space got many to ask it again.
According to Mirror, a Canadian led team of scientists found 13 FRBs with the help of a radio telescope. First discovered in 2007, FRBs are short bursts of radio waves coming from far outside the Milky Way(银河). Scientists have found over 60 FRBs so far. They last only a few milliseconds but release the same energy as the sun gives off in a day.
Among the 13 FRBs, a very unusual repeating signal was found, which came six times from the same location about l.5 billion light-years away. Such an event has only been reported once before, back in 2012. It may help scientists understand where FRBs are from and what causes them. More importantly, the new FRBs were recorded at unusually low radio frequencies. Most of those previously found have had frequencies of around l,400 megahertz (MHz), but new bursts are found at even 400MHz - the lowest frequency the telescope can discover. According to the BBC, the low frequency means that the sources of the bursts have changed. It also suggests humans can learn more about the environment where the bursts come from.
Avid Loeb, a professor from Harvard University, believes the radio waves may be evidence of alien technology. They may be “leakage from a huge, light-powered ship deep in space,” Loeb told The Independent. And even some Chinese internet users joked we shouldn't respond to them. However, most researchers believe that FRBs are formed due to the death of a star or the merging (合并) of two black holes.
“Science isn't a matter of belief, it's a matter of evidence,” claimed Loeb. So only more advanced technology and more collected data will reveal the truth about FRBs. Time will be the judge.
1.What can we learn about the 13 FRBs from the text?
A.They release less energy than the sun does.
B.They are from somewhere in the Milky Way.
C.They cover l.5 billion light-years in a second.
D.The 400MHz FRBs may help man know more.
2.What does the underlined “it” in Paragraph 3 refer to?
A.The year of 2012. B.The same location.
C.The radio telescope. D.The repeating signal.
3.Which statement might Loeb agree with?
A.More is needed to explore FRBs.
B.We shouldn’t respond to the FRBS.
C.FRBs are from sun-powered ships in space.
D.FRBs are formed due to the death of a star.
4.What might be the best title for the text?
A.What Causes FRBs? B.Where Are FRBs From?
C.Are Aliens Signaling to Us? D.Is Science a Matter of Belief?
