Nobel prize in physics awarded to three physicists for discovery of gravitational waves

Three American physicists Rainer Weiss, Barry Barish and Kip Thorne on Tuesday won the Nobel Prize in Physics for discovering the gravitational waves, ripples in the fabric of spacetime, a phenomenon anticipated by Albert Einstein a century ago.

Gravitational waves are extremely faint ripples in the fabric of space and time, generated by some of the most violent events in the universe.

The Royal Swedish Academy of Sciences in Stockholm announced that Rainer Weiss will be awarded one half of the 9m Swedish kronor (£825,000) prize, whereas  Kip Thorne and Barry Barish will share the other half of the prize.

The credit for discovering the gravitational waves will go to all three scientists who led the Laser Interferometer Gravitational-Wave Observatory, or Ligo, experiment, which enabled them to observe gravitational waves in September 2015.

Weiss, emeritus professor of physics at Massachusetts Institute of Technology is an experimentalist who made major contribution in the concept design, funding and the construction of the observatory.

Kip Thorne, who is the professor of theoretical physics at California Institute of Technology made crucial predictions of how to identify the gravitational wave and how it would look.

Barry Barish,  a former particle physicist at California Institute of Technology (now emeritus professor) is credited for getting the experiment off the ground. The scientist saw the project through – it was in danger of being cancelled when he took over as the second director of Ligo in 1994.

Ronald Drever, a Scottish physicist, who alongside Weiss and Thorne played a leading role in developing Ligo, died in March from dementia less than 18 months after gravitational waves were first detected. The Nobel prize is not normally awarded posthumously.

The Ligo is designed to detect a distortion of a thousandth of the diameter of an atomic nucleus across a 4 Km length of laser beam. The phenomenon detected was the collision of two black holes. With the most sophisticated detector, the scientists listened for 20 thousandths of a second as the two giant black holes, one 35 times the mass of the sun, the other slightly smaller, circled around each other. The two objects had begun by circling each other 30 times a second. By the end of the 20 millisecond snatch of data, the two had accelerated to 250 times a second before the final collision and a dark, violent merger.

Nobel Prize was first awarded in 1901 for achievements in science, literature and peace, in accordance to the will left by Swedish business tycoon Alfred Nobel who had bequeathed much of the fortune he generated from his discovery of dynamite.

Among the science prizes, physics has often taken centre stage with laureates including scientific superstars such as Einstein, Niels Bohr and Marie Curie, one of only two women to win a Nobel Prize for Physics.[/vc_column_text][/vc_column][/vc_row]

Cristiano Ronaldo

Cristiano Ronaldo has announced his retirement from international football, bringing his 23-year career with Portugal towards an end.

The 41-year-old Portugal captain said he would hand back the No. 7 shirt of the national team after the November international break. Ronaldo made the announcement in a video message shared on social media.

The decision marks the end of one of the most decorated international careers in men’s football. Ronaldo has made 234 appearances for Portugal and scored 146 goals, both records at international level.

Ronaldo’s Portugal career comes to an end

Ronaldo made his Portugal debut in 2003 and went on to represent the country across more than two decades.

He helped Portugal win their first major international trophy at Euro 2016. He was also part of the teams that won the UEFA Nations League in 2019 and 2025.

Ronaldo’s international career also included six World Cup appearances. His final World Cup came in 2026, when Portugal were eliminated by eventual champions Spain in the last 16.

Ronaldo reflects on 23 years with Portugal

Announcing his decision, Ronaldo said it was not an easy choice and described his time representing Portugal as a privilege and responsibility.

He thanked his family, the Portuguese people, as well as the teammates, coaches and staff who were part of his international journey.

Ronaldo also said that Portugal would always remain a part of him.

Record-breaking international career

Ronaldo leaves the Portugal setup as the men’s all-time leading international goalscorer and the player with the most international appearances.

His 146 goals came across 234 appearances for Portugal. He also became one of only two players, alongside Lionel Messi, to feature at six World Cups.

His international career included major individual records as well as team honours, making his departure one of the biggest moments in modern international football.

What happens next

Ronaldo’s announcement comes after he said he would hand back Portugal’s No. 7 shirt following the November international break.

Portugal have Nations League fixtures during the November window, but Ronaldo’s announcement means his international career is now set to conclude after that break.

US sanctions Indian couple over alleged support for Iran’s shadow fleet

The US has sanctioned an India-based couple and associated entities over allegations that they helped Iranian vessels evade international restrictions through fraudulent maritime registrations.

The United States has imposed sanctions on an India-based couple and several associated entities, accusing them of helping Iran’s shadow fleet transport petroleum while evading international restrictions.

The US Treasury identified the individuals as Suniel Kumar Sharma and his wife, Jaspreet Preeti Shahid. According to the department, the couple operated a network that provided false maritime flags and certifications to vessels involved in transporting Iranian petroleum, including ships linked to Iran’s military and its proxies. 

The sanctions were announced as part of the Trump administration’s Operation Economic Outcast, a campaign aimed at disrupting Iran’s economic networks and oil revenues.

US alleges fraudulent maritime registrations

According to the US Treasury, Sharma and Shahid allegedly established fraudulent maritime registries and classification societies by creating websites that claimed to provide services on behalf of countries that had not authorised them.

The department said the couple’s activities went back to at least 2014, when they allegedly attempted to impersonate the maritime flagging authority of Dominica.

The Treasury further alleged that their network provided registration and certification services to vessels transporting Iranian petroleum, helping them circumvent international restrictions. 

False ship flags and maritime certifications can allow vessels to operate while avoiding regulatory and sanctions-related scrutiny, according to the US authorities.

India-based firms also face sanctions

The US action also covers several India-based companies and entities associated with the alleged network.

Among those designated are Oceaniek Technologies India and Aryavart Ship Management Private Limited. Other entities named by the Treasury include Precept Trends Private Limited, Polynesia Maritime Private Limited, Alexarya Finserv Private Limited, Alexarya Media and Entertainment Private Limited, Viharaboating Private Limited and Aryavart Maritime and Educational Trust.

The Treasury imposed the measures under Executive Order 13902, which targets key sectors of Iran’s economy, including petroleum, petrochemicals and aviation.

US Treasury issues warning

US Treasury Secretary Scott Bessent warned that Washington would continue targeting people and organisations it believes are supporting Iran.

“Under Operation Economic Outcast, you are either with us or against us,” Bessent said, adding that the US would sanction those it believes continue supporting the Iranian regime, whether by land, sea or air. 

Separately, the US also sanctioned Turkey-based Fugo Ground Services Inc, accusing it of providing ground-handling and other services to US-sanctioned Iranian airlines. 

The latest action therefore extends Washington’s sanctions campaign beyond Iranian entities to foreign individuals and companies that the US alleges are helping Tehran’s sanctioned oil and aviation networks.

Mojtaba Khamenei warns against expecting US policy shift after midterms

Iran’s Supreme Leader Mojtaba Khamenei has warned against expecting a change in US policy towards Tehran following the Democratic Party’s victory in the US midterm elections. He also cautioned that any renewed American attacks on Iran would widen the ongoing Middle East war.

Mojtaba

Iran’s Supreme Leader Mojtaba Khamenei has warned against expecting a change in US policy towards Tehran following the Democratic Party’s victory in the US midterm elections. He said those hoping that political changes in Washington would lead to a shift in America’s approach towards Iran were seriously mistaken.

His remarks came after Democrats secured control of both the US House of Representatives and the Senate, dealing a major electoral setback to President Donald Trump and his Republican Party.

In a message posted on the social media platform X on Wednesday, November 4, Khamenei said Iranians understood their position towards the United States more clearly than ever. He also said that examining the reasons behind what he described as US hostility and Iran’s resistance would provide guidance for the country’s future course.

Khamenei cautioned against viewing changes in the political balance in Washington as an indication that American policy towards Iran would become less hostile.

Khamenei Warns Of Wider Middle East War

The Iranian Supreme Leader also warned that the ongoing Middle East war could expand further if the United States resumed its attacks on Iran.

“Should such aggressions be repeated, its (the war) scope will become much wider,” he said.

His warning comes amid continuing tensions between Washington and Tehran, with the conflict involving the two countries remaining a major issue in US politics.

Democrats Take Control Of Both Houses Of Congress

The Democratic Party secured control of both chambers of the US Congress in the midterm elections, marking a significant setback for Trump’s Republicans.

The party benefited from public dissatisfaction with Trump and gained greater power to scrutinise and challenge his administration during the final two years of his presidency.

Trump, meanwhile, struck a conciliatory tone in an interview with The New York Times, saying he was “absolutely willing to accept those results” and was prepared to work with Democrats.

Iran War Emerged As A Key Election Issue

The war involving Iran was among the major issues during the US midterm election campaign.

Democratic candidates criticised Trump over the conflict and linked it to economic difficulties that had contributed to frustration among voters across the country.

Khamenei’s remarks, however, indicated that Tehran does not expect the change in congressional control to result in a fundamental shift in Washington’s approach towards Iran.
