Astronomers Detect Ultra-Energetic Fast Radio Burst From 8 Billion Years Ago

RADIO

(CTN NEWS) – Astronomers have made a remarkable discovery, detecting a powerful and enigmatic radio wave burst known as a fast radio burst (FRB) that has traveled an astonishing 8 billion years to reach Earth.

This FRB is not only one of the most distant ever observed but also one of the most energetic.

Fast radio bursts, or FRBs, are intense bursts of radio waves that last just milliseconds, and their origins remain a mystery.

The first FRB was identified in 2007, and since then, scientists have detected hundreds of these rapid, celestial flashes emanating from distant corners of the cosmos.

The FRB in question, named FRB 20220610A, was an extremely brief event, lasting less than a millisecond.

However, during this minuscule fraction of time, it released the equivalent energy of our sun’s emissions over the course of 30 years.

This astonishing finding was reported in a study published in the journal Science.

The challenge with FRBs lies in their fleeting nature; they typically emit incredibly bright radio waves that endure for just milliseconds before vanishing, making them difficult to study.

The use of radio telescopes, including the ASKAP array of radio telescopes located on Wajarri Yamaji Country in Western Australia, has been instrumental in tracking these rapid cosmic phenomena.

Astronomers employed ASKAP to detect the FRB in June 2022 and pinpoint its source of origin, shedding light on this extraordinary event.

The use of ASKAP’s array of radio dishes enabled the research team to pinpoint the exact origin of the burst, as explained by study coauthor Dr. Stuart Ryder, an astronomer at Macquarie University in Australia.

He stated, “Using ASKAP’s array of (radio) dishes, we were able to determine precisely where the burst came from.”

To further investigate the source galaxy, they employed the European Southern Observatory’s Very Large Telescope in Chile.

The results revealed that the source galaxy is older and more distant than any other known FRB source, likely residing within a small group of merging galaxies.

This discovery aligns with existing theories that propose fast radio bursts may be linked to magnetars, highly energetic celestial objects resulting from stellar explosions.

Scientists believe that FRBs may offer a unique method for “weighing” the universe by measuring the unaccounted-for matter between galaxies.

Study coauthor Ryan Shannon, a professor at Swinburne University of Technology in Australia, explained, “If we count up the amount of normal matter in the Universe — the atoms that we are all made of — we find that more than half of what should be there today is missing.”

This missing matter is thought to exist in the space between galaxies, but it may be so hot and diffuse that conventional observation techniques cannot detect it.

Currently, the methods used to estimate the mass of the universe do not produce consistent results, suggesting that a significant portion of the universe’s matter is unaccounted for.

As Shannon points out, fast radio bursts have the unique ability to sense ionized material, even in extremely empty regions of space, providing insights into the matter distributed between galaxies.

This capability could prove essential in solving the mystery of the universe’s missing mass.

Australian astronomer Jean-Pierre Macquart’s work in 2020 highlighted the potential of using fast radio bursts (FRBs) to detect missing matter in the universe, establishing what is now known as the Macquart relation.

This relationship indicates that the farther away an FRB is, the more diffuse gas it reveals between galaxies.

The recent study confirms that the Macquart relation holds true for FRBs extending beyond half of the known universe.

To date, almost 50 FRBs have been traced back to their sources, with approximately half of them identified using ASKAP.

While the exact cause of these powerful bursts of energy remains unknown, the study underscores that FRBs are relatively common events in the cosmos.

They have the potential to help detect matter between galaxies and enhance our understanding of the universe’s structure.

Future radio telescopes currently under construction in South Africa and Australia are expected to facilitate the detection of thousands more FRBs at greater distances.

This expanded dataset could allow for a comprehensive mapping of the universe’s structure and offer insights into fundamental cosmological questions.

In the words of astronomer Ryan Shannon, “The fact that FRBs are so common is also amazing“.

It shows how promising the field can be, because you’re not just going to do this for 30 bursts, you can do this for 30,000 bursts, make a new map of the structure of the universe, and use it to answer big questions about cosmology.”

Google’s Search Dominance Is Unwinding, But Still Accounting 48% Search Revenue

Google

Google is so closely associated with its key product that its name is a verb that signifies “search.” However, Google’s dominance in that sector is dwindling.

According to eMarketer, Google will lose control of the US search industry for the first time in decades next year.

Google will remain the dominant search player, accounting for 48% of American search advertising revenue. And, remarkably, Google is still increasing its sales in the field, despite being the dominating player in search since the early days of the George W. Bush administration. However, Amazon is growing at a quicker rate.

Google’s Search Dominance Is Unwinding

Amazon will hold over a quarter of US search ad dollars next year, rising to 27% by 2026, while Google will fall even more, according to eMarketer.

The Wall Street Journal was first to report on the forecast.

Lest you think you’ll have to switch to Bing or Yahoo, this isn’t the end of Google or anything really near.

Google is the fourth-most valued public firm in the world. Its market worth is $2.1 trillion, trailing just Apple, Microsoft, and the AI chip darling Nvidia. It also maintains its dominance in other industries, such as display advertisements, where it dominates alongside Facebook’s parent firm Meta, and video ads on YouTube.

To put those “other” firms in context, each is worth more than Delta Air Lines’ total market value. So, yeah, Google is not going anywhere.

Nonetheless, Google faces numerous dangers to its operations, particularly from antitrust regulators.

On Monday, a federal judge in San Francisco ruled that Google must open up its Google Play Store to competitors, dealing a significant blow to the firm in its long-running battle with Fortnite creator Epic Games. Google announced that it would appeal the verdict.

In August, a federal judge ruled that Google has an illegal monopoly on search. That verdict could lead to the dissolution of the company’s search operation. Another antitrust lawsuit filed last month accuses Google of abusing its dominance in the online advertising business.

Meanwhile, European regulators have compelled Google to follow tough new standards, which have resulted in multiple $1 billion-plus fines.

Google’s Search Dominance Is Unwinding

On top of that, the marketplace is becoming more difficult on its own.

TikTok, the fastest-growing social network, is expanding into the search market. And Amazon has accomplished something few other digital titans have done to date: it has established a habit.

When you want to buy anything, you usually go to Amazon, not Google. Amazon then buys adverts to push companies’ products to the top of your search results, increasing sales and earning Amazon a greater portion of the revenue. According to eMarketer, it is expected to generate $27.8 billion in search revenue in the United States next year, trailing only Google’s $62.9 billion total.

And then there’s AI, the technology that (supposedly) will change everything.

Why search in stilted language for “kendall jenner why bad bunny breakup” or “police moving violation driver rights no stop sign” when you can just ask OpenAI’s ChatGPT, “What’s going on with Kendall Jenner and Bad Bunny?” in “I need help fighting a moving violation involving a stop sign that wasn’t visible.” Google is working on exactly this technology with its Gemini product, but its success is far from guaranteed, especially with Apple collaborating with OpenAI and other businesses rapidly joining the market.

A Google spokeswoman referred to a blog post from last week in which the company unveiled ads in its AI overviews (the AI-generated text that appears at the top of search results). It’s Google’s way of expressing its ability to profit on a changing marketplace while retaining its business, even as its consumers steadily transition to ask-and-answer AI and away from search.

Google has long used a single catchphrase to defend itself against opponents who claim it is a monopoly abusing its power: competition is only a click away. Until recently, that seemed comically obtuse. Really? We are going to switch to Bing? Or Duck Duck Go? Give me a break.

But today, it feels more like reality.

Google is in no danger of disappearing. However, every highly dominating company faces some type of reckoning over time. GE, a Dow mainstay for more than a century, was broken up last year and is now a shell of its previous dominance. Sears declared bankruptcy in 2022 and is virtually out of business. US Steel, long the foundation of American manufacturing, is attempting to sell itself to a Japanese corporation.

Could we remember Google in the same way that we remember Yahoo or Ask Jeeves in decades? These next few years could be significant.

2024 | Supreme Court Won’t Hear Appeal From Elon Musk’s X Platform Over Warrant In Trump Case

trump

Washington — Trump Media,  The Supreme Court announced Monday that it will not hear an appeal from social media platform X about a search warrant acquired by prosecutors in the election meddling case against former President Donald Trump.

The justices did not explain their rationale, and there were no recorded dissents.

The firm, which was known as Twitter before being purchased by billionaire Elon Musk, claims a nondisclosure order that prevented it from informing Trump about the warrant obtained by special counsel Jack Smith’s team violated its First Amendment rights.

The business also claims Trump should have had an opportunity to exercise executive privilege. If not reined in, the government may employ similar tactics to intercept additional privileged communications, their lawyers contended.

Two neutral electronic privacy groups also joined in, urging the high court to hear the case on First Amendment grounds.

Prosecutors, however, claim that the corporation never shown that Trump utilized the account for official purposes, therefore executive privilege is not a problem. A lower court also determined that informing Trump could have compromised the current probe.

Trump utilized his Twitter account in the weeks preceding up to his supporters’ attack on the Capitol on January 6, 2021, to spread false assertions about the election, which prosecutors claim were intended to create doubt in the democratic process.

The indictment describes how Trump used his Twitter account to encourage his followers to travel to Washington on Jan. 6, pressuring Vice President Mike Pence to reject the certification, and falsely claiming that the Capitol crowd, which battered police officers and destroyed glass, was peaceful.

That case is now moving forward following the Supreme Court’s verdict in July, which granted Trump full immunity from criminal prosecution as a former president.

The warrant arrived at Twitter amid quick changes implemented by Musk, who bought the company in 2022 and has since cut off most of its workforce, including those dedicated to combating disinformation and hate speech.

He also welcomed back a vast list of previously banned users, including Trump, and endorsed him for the 2024 presidential election.

The Supreme Court Turns Down Biden’s Government Appeal in a Texas Emergency Abortion Matter.

Supreme Court

(VOR News) – A ruling that prohibits emergency abortions that contravene the Supreme Court law in the state of Texas, which has one of the most stringent abortion restrictions in the country, has been upheld by the Supreme Court of the United States. The United States Supreme Court upheld this decision.

The justices did not provide any specifics regarding the underlying reasons for their decision to uphold an order from a lower court that declared hospitals cannot be legally obligated to administer abortions if doing so would violate the law in the state of Texas.

Institutions are not required to perform abortions, as stipulated in the decree. The common populace did not investigate any opposing viewpoints. The decision was made just weeks before a presidential election that brought abortion to the forefront of the political agenda.

This decision follows the 2022 Supreme Court ruling that ended abortion nationwide.

In response to a request from the administration of Vice President Joe Biden to overturn the lower court’s decision, the justices expressed their disapproval.

The government contends that hospitals are obligated to perform abortions in compliance with federal legislation when the health or life of an expectant patient is in an exceedingly precarious condition.

This is the case in regions where the procedure is prohibited. The difficulty hospitals in Texas and other states are experiencing in determining whether or not routine care could be in violation of stringent state laws that prohibit abortion has resulted in an increase in the number of complaints concerning pregnant women who are experiencing medical distress being turned away from emergency rooms.

The administration cited the Supreme Court’s ruling in a case that bore a striking resemblance to the one that was presented to it in Idaho at the beginning of the year. The justices took a limited decision in that case to allow the continuation of emergency abortions without interruption while a lawsuit was still being heard.

In contrast, Texas has been a vocal proponent of the injunction’s continued enforcement. Texas has argued that its circumstances are distinct from those of Idaho, as the state does have an exemption for situations that pose a significant hazard to the health of an expectant patient.

According to the state, the discrepancy is the result of this exemption. The state of Idaho had a provision that safeguarded a woman’s life when the issue was first broached; however, it did not include protection for her health.

Certified medical practitioners are not obligated to wait until a woman’s life is in imminent peril before they are legally permitted to perform an abortion, as determined by the state supreme court.

The state of Texas highlighted this to the Supreme Court.

Nevertheless, medical professionals have criticized the Texas statute as being perilously ambiguous, and a medical board has declined to provide a list of all the disorders that are eligible for an exception. Furthermore, the statute has been criticized for its hazardous ambiguity.

For an extended period, termination of pregnancies has been a standard procedure in medical treatment for individuals who have been experiencing significant issues. It is implemented in this manner to prevent catastrophic outcomes, such as sepsis, organ failure, and other severe scenarios.

Nevertheless, medical professionals and hospitals in Texas and other states with strict abortion laws have noted that it is uncertain whether or not these terminations could be in violation of abortion prohibitions that include the possibility of a prison sentence. This is the case in regions where abortion prohibitions are exceedingly restrictive.

Following the Supreme Court’s decision to overturn Roe v. Wade, which resulted in restrictions on the rights of women to have abortions in several Republican-ruled states, the Texas case was revisited in 2022.

As per the orders that were disclosed by the administration of Vice President Joe Biden, hospitals are still required to provide abortions in cases that are classified as dire emergency.

As stipulated in a piece of health care legislation, the majority of hospitals are obligated to provide medical assistance to patients who are experiencing medical distress. This is in accordance with the law.

The state of Texas maintained that hospitals should not be obligated to provide abortions throughout the litigation, as doing so would violate the state’s constitutional prohibition on abortions. In its January judgment, the 5th United States Circuit Court of Appeals concurred with the state and acknowledged that the administration had exceeded its authority.
