Fast radio bursts (FRBs) are extremely powerful flashes of radio waves that last only a fraction of a second but can release about as much energy as the sun does in a year. Their light also forms a laserlike beam, setting them apart from more chaotic cosmic events.
Scientists have been puzzled by the origin and nature of these elusive signals for over a decade. Most FRBs detected so far have come from distant galaxies, making pinpointing their exact source and cause difficult.
Fast radio bursts (FRBs) are one of the most mysterious phenomena in the universe.

Scientists have been puzzled by the origin and nature of these elusive signals for over a decade. Most FRBs detected so far have come from distant galaxies, making pinpointing their exact source and cause difficult. However, in 2020, astronomers detected the first FRB from within our Milky Way galaxy and traced it to a type of dead star called a magnetar.
NASA X-ray telescopes have observed a fast radio burst (FRB) from a magnetar within our galaxy.
SGR 1935+2154, an extremely dense object called a magnetar, produced another FRB which was studied by NASA telescopes on the International Space Station and low Earth orbit.

The article is deceptive in several ways. Firstly, it states that NASA telescopes have unlocked the secrets behind mysterious deep space signals when in fact they only observed one such event and cannot make any generalizations about all fast radio bursts (FRBs). Secondly, the article claims that FRBs are generated by magnetars but does not provide evidence to support this claim. Thirdly, the article uses sensationalist language such as 'mysterious' and 'extreme' to create a sense of urgency and importance around FRBs when in fact there is no need for such exaggeration.
The article claims that fast radio bursts (FRBs) are generated by magnetars. However, there is no evidence provided to support this claim. The article simply states that the burst occurred on a magnetar but does not provide any information about how or why this happened.
The article states that NASA telescopes have unlocked the secrets behind mysterious deep space signals. However, this statement is misleading as it implies that all FRBs can be explained by observations made with NASA telescopes. In reality, only one FRB has been observed and studied in detail using these telescopes.

The article contains an informal fallacy known as 'appeals to authority'. The author cites NASA's X-ray telescopes and the NICER (Neutron Star Interior Composition Explorer) on the International Space Station without providing any evidence or context for their reliability. Additionally, there is a lack of clarity in how these instruments were used to observe and study SGR 1935+2154.
The discovery team studied a magnetar that is considered the most active in our galaxy over the last decade and located an estimated 30,000 light-years away from Earth using NICER instrument aboard International Space Station and NuSTAR space telescope. They spotted two massive glitches associated with the magnetar separated by around nine hours.
The first glitch caused an increase in rotation speed of the star while the second one caused yet another speed increase 100 times greater than the first, decelerating at a rate 100 times faster than its speed before and approximately 1,000 times faster than its long-term average.
Exactly between these two glitches, SGR launched an FRB. After both acceleration jumps, the neutron star somehow slowed back down to its normal rotation rate.

The article is deceptive in several ways. Firstly, the author claims that these glitches have massively accelerated the star's spin speed when in fact they only caused a temporary increase and then another even larger one. Secondly, the author states that during this interval between two glitches SGR 1935 launched an FRB but fails to mention that it also experienced a significant decrease in rotation speed before launching the FRB. This is misleading as it implies that the star was spinning at its normal rate when it launched the FRB, which is not true. Lastly, the author claims that these glitches are due to superfluid material inside neutron stars but fails to provide any evidence or explanation for this claim.
The article states that 'the first glitch caused an increase in rotation speed'. However, it does not mention what happened after the first glitch. In fact, there was another even larger glitch nine hours later which caused a much greater increase in rotation speed than the first one. This is misleading as it implies that the star's spin rate remained constant between these two glitches.
The article states that 'these glitches are due to superfluid material inside neutron stars'. However, no evidence or explanation for this claim is provided. This statement is deceptive as it implies a level of understanding and knowledge which may not be supported by scientific research.
The article states that 'during this interval between two glitches SGR 1935 launched an FRB'. However, it does not mention what happened before or after launching the FRB. In fact, there was a significant decrease in rotation speed before launching the FRB which is misleading as it implies that the star's spin rate remained constant until launching the FRB.

The article discusses the discovery of two massive glitches in a highly magnetic neutron star (SGR 1935) that caused an increase and then another increase in rotation speed. The first glitch increased the rotation speed by approximately 20 times, while the second one increased it by around 100 times. However, between these two glitches, SGR 1935 launched a Fast Radio Burst (FRB). After both acceleration-jumps, the neutron star somehow slowed back down to its normal rotation rate. The article suggests that this slowdown occurred over a period longer than the duration of the glitches themselves and is likely due to an ephemeral magnetospheric wind blowing from the star. This wind would carry away angular momentum that rapidly slows down the star's rotational rate.
The discovery team studied a magnetar that's considered the most active in our galaxy over the last decade, SGR 1935 (SGR 1935).
Each brief observation allows us to measure the rotation speed of the magnetar and we noticed that suddenly the star was spinning faster than before.
During this interval between these two glitches, SGR 1935 launched an FRB.

The article discusses the discovery of two massive glitches in a highly magnetic neutron star (SGR 1935) that caused an increase and then another increase in rotation speed. The first glitch increased the rotation speed by about 20 times, while the second one increased it by over 100 times. This is significant because magnetars are known to launch Fast Radio Bursts (FRBs), which are mysterious and fleeting pulses of light that can get bright enough to briefly outshine an entire galaxy. The discovery team studied SGR 1935 using the Neutron Star Interior Composition Explorer (NICER) instrument aboard the International Space Station as well as the Nuclear Spectroscopic Telescope Array (NuSTAR) space telescope. They found that between these two glitches, SGR 1935 launched an FRB. The article also discusses how magnetars are formed and their unique properties, such as being composed of exotic matter with a density so high that a teaspoonful would weigh something like 1 billion tons.

The author has a conflict of interest on the topic of fast radio bursts (FRB) as they are reporting on a discovery made by NASA which is an organization with whom the author may have professional affiliations.
The leading theory is that FRBs are caused by highly magnetic neutron stars known as magnetars.
With observatories such as CHIME, astronomers have been able to see lots of FRBs which could give them a new way to measure the rate of cosmic expansion. The rate of cosmic expansion is described by the Hubble parameter and we can measure it within a few percent using various methods but their uncertainties don't overlap.
The paper proposes using FRBs as a Hubble measure. For light from an FRB to reach us, it needs to travel millions of light-years through the diffuse intergalactic and interstellar medium which causes the frequency of the light to spread out. The amount of spectral spreading is known as Dispersion Measure (DM) and we know that greater DM means greater distance.
The geometry of an FRB measurement allows us to calculate the Hubble parameter based on our calculations. A single lensed FRB observation would allow them to pin down the Hubble parameter within 6% accuracy and with 30 or more events, they should be able to increase their precision to a fraction of a percent uncertainty.
This new method is one way we can resolve the Hubble tension which contradicts our various methods of measure. The authors estimate that this method would put it on par with other methods.
Accuracy
To measure cosmic expansion, we also need a second distance measure. The paper proposes using gravitational lensing for this purpose.

Secondly, the author states that with observatories such as CHIME we can see lots of them which could give astronomers a new way to measure cosmic expansion, however they do not explain how FRBs are used for measuring distances in the universe. Thirdly, the article claims that by using gravitational lensing and scintillation effects on FRB light paths we can calculate the Hubble parameter with high accuracy but does not provide any details about these calculations or their reliability.
The author states that FRBs are caused by highly magnetic neutron stars known as magnetars without providing evidence to support this claim. This is a lie by omission.

The author has a clear bias towards the idea that fast radio bursts (FRBs) can be used to measure cosmic expansion. The author mentions several times how FRBs could provide an independent way to measure the Hubble parameter and solve the Hubble tension. Additionally, the author uses language such as 'we still aren't sure what they are' when referring to FRBs which implies a sense of mystery or excitement about their nature.
The rate of cosmic expansion is described by the Hubble parameter, which we can measure to within a few percent. Unfortunately, our various methods of measure are now so precise their uncertainties don't overlap.
