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]

Trump rejects Iran’s 7-day peace plan, says deal can come after US polls

US President Donald Trump rejected Iran’s seven-day proposal to end hostilities and indicated that a deal could come after the US midterm elections in November.

Donald Trump

US President Donald Trump has rejected Iran’s latest proposal aimed at bringing an end to the ongoing conflict, while indicating that a possible agreement could come after the US midterm elections in November.

Iran had proposed a seven-day framework under which hostilities could be brought to an end, the Strait of Hormuz could be reopened and negotiations over its nuclear programme could resume.

Iran’s seven-day proposal

Iranian Foreign Minister Abbas Araghchi said Tehran had put forward the proposal through intermediaries. Under the plan, the Strait of Hormuz would be reopened by the end of the seventh day if specified conditions were met, while broader nuclear discussions would restart.

The proposal was based largely on an earlier understanding reached between Washington and Tehran, but Iran sought to implement the latest framework much faster. The earlier arrangement had provided a longer period for negotiations.

The Strait of Hormuz is a strategically important waterway for global energy shipments, making its reopening a key element of any effort to ease the wider conflict.

Trump points to US midterm elections

Trump, speaking at the United Nations, showed no indication that he was ready to immediately resume negotiations on the terms proposed by Tehran.

He called for the economic isolation of Iran and said he believed a deal could be reached after the US midterm elections in November. Trump also said Iran was waiting to see how he performed in the midterm elections.

The remarks came as Iranian officials signalled that they remained open to diplomacy and described the UN General Assembly as an opportunity to revive negotiations.

Nuclear talks remain part of Iran proposal

Iran’s latest plan links the easing of hostilities with the resumption of negotiations over its nuclear programme.

The proposal follows the collapse of an earlier US-Iran arrangement. According to reporting on the latest proposal, the new framework is intended to compress the timeline for implementing commitments that had previously been discussed by the two sides.

For now, Trump’s remarks indicate that Washington is not accepting Tehran’s seven-day framework as presented, while Iran continues to put diplomacy and negotiations forward as part of its proposal.

Iranian President Pezeshkian at UN says Iranians have been victims of US terrorism

Iranian President Masoud Pezeshkian said at the UN General Assembly that Iranians had been victims of US terrorism and insisted that Iran had acted in self-defence.

Iranian President Masoud Pezeshkian accused the United States of subjecting Iranians to what he described as terrorism while addressing the United Nations General Assembly on Wednesday.

Pezeshkian said Iran had defended itself against attacks and rejected the characterisation of the country as a terrorist actor. His remarks came during a rare wartime appearance at the UN as tensions between Iran and the United States remain high.

Pezeshkian accuses US and Israel of attacks

Speaking at the General Assembly, Pezeshkian said Iranian civilians had been targeted by attacks and described the actions against his country as aggression.

“We have only defended ourselves. We are not terrorists,” he said, according to the report.

Pezeshkian also accused the United States and Israel of attacking Iran, while maintaining that Tehran’s response was an act of self-defence.

The Iranian president displayed photographs of former Supreme Leader Ali Khamenei and more than 150 schoolchildren who, according to his account, were killed during the early days of the conflict.

Iran’s message at the UN

Pezeshkian’s address came against the backdrop of the ongoing conflict between Iran and the United States and heightened tensions in the region.

Iranian officials had indicated ahead of the UN visit that they intended to highlight what Tehran considers attacks against its people and raise concerns over the international response to the conflict.

The Iranian delegation’s visit to New York also comes amid restrictions imposed by the United States on the delegation’s movement and other aspects of its stay, according to reporting ahead of the address.

Pezeshkian says Iran defended itself

Pezeshkian’s central message at the UN was that Iran’s military actions should be viewed as a response to attacks rather than terrorism.

His description of the conflict and the allegations against the United States and Israel represent the Iranian government’s position. They should therefore be attributed to Pezeshkian rather than presented as independently established facts.

Canadian Prime Minister Mark Carney has said he is looking forward to hosting Prime Minister Narendra Modi, as India and Canada continue efforts to advance their bilateral relationship and conclude ongoing trade negotiations.

The two countries have been working towards a Comprehensive Economic Partnership Agreement (CEPA), with both sides previously setting a target to conclude the negotiations in 2026.

Carney and Modi have held discussions on strengthening economic ties between India and Canada, including trade and investment. Their engagement has gained momentum following Carney’s visit to India earlier this year.

India-Canada trade talks

India and Canada formally resumed efforts towards a broader trade agreement after a period of strained bilateral ties. The two sides have committed to advancing negotiations on a CEPA covering their economic relationship.

In June, Carney and Modi reviewed progress in bilateral economic cooperation during their meeting on the sidelines of the G7 Summit in France. They expressed satisfaction with the progress in CEPA negotiations and reaffirmed their shared objective of concluding the talks in 2026.

During Carney’s visit to India in March, the two leaders had also agreed to accelerate negotiations on the CEPA and work towards finalising the agreement during 2026.

Modi’s proposed Canada visit

Carney had invited PM Modi to visit Canada in 2026, and the two leaders agreed to remain engaged through diplomatic channels to work towards a mutually convenient date for the visit.

The proposed visit comes as New Delhi and Ottawa seek to build on renewed diplomatic and economic engagement, with trade negotiations remaining a key part of the relationship.

The focus on completing the trade talks comes as both countries look to expand commercial ties and establish a broader economic framework through the proposed CEPA.
