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]

PoK protest leader seeks India’s help amid Pakistan crackdown, alleges humanitarian crisis

JAAC leader Sardar Aman Khan has appealed to India for humanitarian assistance, alleging shortages of food and medicines amid Pakistan’s crackdown on protesters in Pakistan-occupied Kashmir.

The leader of the Joint Awami Action Committee (JAAC), Sardar Aman Khan, has appealed to India for humanitarian assistance amid the ongoing unrest in Pakistan-occupied Kashmir (PoK), claiming that the region is facing severe shortages of essential supplies following a crackdown by Pakistani authorities.

According to Khan, residents are struggling to access food and medicines as security operations against protesters continue. He also urged India to consider opening the Line of Control (LoC) to allow humanitarian assistance and provide civilians with the option of crossing into India if the situation worsens.

JAAC chief calls for humanitarian assistance

Speaking at a public gathering, Khan claimed that an economic blockade imposed after the crackdown had created serious hardships for people in the region.

In a video that has circulated widely on social media, he is heard saying that PoK residents need India’s assistance due to shortages of essential commodities.

He also appealed for the opening of crossing points along the LoC, particularly in the Poonch and Doda sectors, alleging that the ongoing restrictions had further intensified the humanitarian situation.

During the rally at Rawalakot’s Eidgah Ground, Khan asked the crowd whether they should move towards the Line of Control. The gathering repeatedly responded in support of the proposal.

He further warned that if public demands continued to be met with force, people could consider other options.

It is important to note that the authenticity of the viral video, reportedly from Khan’s June 30 rally, has not been independently verified.

Protests continue across PoK

The appeal comes as demonstrations continue across Pakistan-occupied Kashmir, where protests against the Pakistani administration have been ongoing since last month.

During a recent rally at Eidgah Ground, protesters raised slogans including “PoK is not part of Pakistan” and “We want freedom,” indicating that the movement has expanded beyond demands for reforms to include calls for independence from Pakistan’s political control over the region.

Crackdown follows ban on JAAC

The unrest intensified after Pakistani authorities banned the Joint Awami Action Committee on June 5, designating the grassroots organisation as a terrorist group.

According to a recent report by the International Centre for Peace Studies, Pakistan has historically exercised significant political control over Pakistan-occupied Kashmir and Pakistan-occupied Gilgit-Baltistan through mainstream political parties aligned with Islamabad.

The report also noted that the ruling party in Islamabad has consistently won elections in both regions, suggesting a long-standing pattern of political influence.

Meanwhile, several analysts have argued that the ongoing crisis reflects growing dissatisfaction among local residents with the regional administration, which they describe as lacking independent authority. They also contend that the ban on the JAAC and the use of force against protesters are part of broader efforts to suppress the expanding protest movement.

Crowds attending a funeral ceremony in Iran raised chants of “Death to Trump” as the country’s Supreme Leader, Ayatollah Ali Khamenei, made a public appearance during the event.

The slogans were heard as thousands gathered to pay tribute to those killed during the recent conflict involving Iran and Israel. The ceremony also marked one of Ayatollah Khamenei’s notable public appearances after the military escalation that had heightened tensions across the region.

Anti-US slogans raised during ceremony

Videos circulating from the funeral ceremony showed mourners chanting “Death to America” and “Death to Trump” while Ayatollah Khamenei attended the event. Such slogans have long been associated with state-backed public gatherings in Iran and were repeated during the ceremony attended by senior Iranian officials and large crowds.

The funeral was held to honour military commanders, nuclear scientists and other individuals who Iran says were killed during the recent conflict. The gathering drew thousands of people to the capital, where processions and official tributes were organised.

Public appearance after recent conflict

Ayatollah Khamenei’s appearance came after weeks of heightened tensions in the Middle East following Israeli strikes on Iranian targets and subsequent military exchanges between the two countries. The conflict also saw the United States carry out strikes on Iranian nuclear facilities, further escalating regional tensions.

The funeral ceremony was among the Supreme Leader’s most significant public appearances since the conflict, with state media extensively covering the event.

Regional tensions remain high

Relations between Iran, Israel and the United States remain strained despite the ceasefire announced following the recent hostilities. Officials from the three countries continue to exchange strong statements over the military operations and the future of Iran’s nuclear programme.

The funeral ceremony reflected the continuing anti-US and anti-Israel sentiment expressed by sections of the Iranian establishment and supporters attending the event.
