Washington, Apr 10: Scientists released the much-awaited first direct image of a massive black hole at the centre of Messier 87, a galaxy which is about 54 million light-years away, at the National Press Club here on Wednesday. 

The image has been taken by the Event Horizon Telescope (EHT), which is a network of 10 radio telescopes spread across the planet, according to The Washington Post. The telescope functioned as if it is a single receiver, tuned to high-frequency radio waves, to take the image. 

The picture - released at six simultaneous news conferences on Wednesday - shows the event horizon, which is the boundary between light and dark around a black hole. A doughnut-like body can be seen in the portrait, which scientists say is the dark silhouette of the black hole against the hot, glowing material that surrounds it. 

"We are able to image one more object in the universe that ... at one point people thought could not be possible. It hits that human explorer spirit. We got another look into the unknown," Feryal Ozel, a member of the science council for the EHT said, calling the occasion her career's highlight.
 
The shape of the black hole matches what theorists had predicted ever since they started wrestling with Albert Einstein, General Theory of Relatively over a hundred years ago, reports The Washington Post. 

The European Commission hailed the occasion as a "paradigm shift" adding, "This major scientific achievement marks a paradigm shift in our understanding of black holes, confirms the predictions of Albert Einstein's General Theory of Relativity and opens up new lines of enquiry into our universe."

Karachi, May 29: Investigators and rescue officials have found around Rs 3 crore in cash in the wreckage of the Pakistan International Airlines' aircraft that crashed wth 99 people on board, killing 97 people, including nine children.

Flight PK-8303 from Lahore to Karachi crashed in a residential area near Karachi International Airport on Friday, with only two passengers miraculously surviving the crash.

Investigators and rescue officials have found currencies of different countries and denominations worth around Rs 30 million from the aircraft's wreckage, an official said on Thursday.

"An investigation has been ordered into how such a huge amount of cash got through airport security and baggage scanners and found its way into the ill-fated flight," the official said.

He said that the amount was recovered from two bags in the wreckage.

"The process of identifying the bodies and their luggage which will be handed over to their families and relatives is going on," he said.

A total of 97 people including the aircraft crew died in the crash, one of the most catastrophic aviation disasters in Pakistan's history.

A government official said on Thursday that the identification of 47 bodies had been completed, while 43 bodies were handed over for burial.

Friday's accident was the first major aircraft crash in Pakistan after December 7, 2016 when a PIA ATR-42 aircraft from Chitral to Islamabad crashed midway. The crash claimed the lives of all 48 passengers and crew, including singer-cum-evangelist Junaid Jamshed.

New Delhi, Jun 16: Despite Prime Minister Narendra Modi led government’s attempt to downplay the border dispute with China, matters have heated up unprecedentedly along the Line of Actual Control (LAC)- the effective Sino-India border in Eastern Ladakh. 

The country has lost three precious lives – an army officer and two soldiers. The last time blood was spilled on the LAC, before the latest episode, was 45 years ago when the Chinese ambushed an Assam Rifles patrol in Tulung La.

India had lost four soldiers on October 20, 1975 in Tulung La, the last time bullets were fired on the India-China border though both the countries witnessed bitter stand-offs later at Sumdorong Chu valley in 1987, Depsang in 2013, Chumar in 2014 and Doklam in 2017.

Between 1962 and 1975, the biggest clash between India and China took place in Nathu La pass in 1967 when reports suggest that around 80 Indian soldiers were killed and many more Chinese personnel.

While three soldiers, including a Commanding Officer, were killed in the latest episode in Galwan Valley, the government describes it as a "violent clash" and does not mention opening fire.

New Delhi described the locality where the 1975 incident took place as "well within" its territory only to be rebuffed by Beijing as "sheer reversal of black and white and confusion of right and wrong".

The Ministry of External Affairs had then said that the Chinese had crossed the LAC and ambushed the soldiers while Beijing claimed the Indians entered their territory and did not return despite warnings.

The Indian government maintained that the ambush on the Assam Rifles' patrol in 1975 took place "500 metres south of Tulung" on the border between India and Tibet and "therefore in Indian territory". It said Chinese soldiers "penetrating" Indian territory implied a "change in China's position" on the border question but the Chinese denied this and blamed India for the incident.

The US diplomatic cables quoted an Indian military intelligence officer saying that the Chinese had erected stone walls on the Indian side of Tulung La and from these positions fired several hundred rounds at the Indian patrol.

"Four of the Indians had gone into a leading position while two (the ones who escaped) remained behind. The senior military intelligence officer emphasised that the soldiers on the Indian patrol were from the area and had patrolled that same region many times before," the cable said.

One of the US cables showed that former US Secretary of State and National Security Adviser Henry Kissinger sought details of the October 1975 clash "without approaching the host governments on actual location of October 20 incident". He also wanted to know what ground rules were followed regarding the proximity of LAC by border patrols.

A cable sent from the US mission in India on November 4, 1975 appeared to have doubts about the Chinese account saying it was "highly defensive".

"Given the unsettled situation on the sub-continent, particularly in Bangladesh, both Chinese and Indian authorities have authorised stepped up patrols along the disputed border. The clash may well have ensued when two such patrols unexpectedly encountered each other," it said.

Another cable from China on the same day quoted another October 1974 cable, which spoke about Chinese officials being concerned for long that "some hotheaded person on the PRC (People's Republic of China) might provoke an incident that could lead to renewed Sino-Indian hostilities. It went on to say that this clash suggested that "such concerns and apprehensions are not unwarranted".

According to the United States diplomatic cables, Chinese Foreign Ministry on November 3, 1975 disputed the statement of the MEA spokesperson, who said the incident took place inside Indian territory.

The Chinese had said "sheer reversal of black and white and confusion of right and wrong". In its version of the 1975 incident, they said Indian troops crossed the LAC at 1:30 PM at Tulung Pass on the Eastern Sector and "intruded" into their territory when personnel at the Civilian Checkpost at Chuna in Tibet warned them to withdraw.

Ignoring this, they claimed, Indian soldiers made "continual provocation and even opened fire at the Chinese civilian checkpost personnel, posing a grave threat to the life of the latter. The Chinese civilian checkpost personnel were obliged to fire back in self defence."

The Chinese Foreign Ministry spokesperson had also said they told the Indian side that they could collect the bodies "anytime" and on October 28, collected the bodies, weapons and ammunition and "signed a receipt".

The US cables from the then USSR suggested that the official media carried reports from Delhi on the October 1975 incident and they cited only Indian accounts of the incident "ridiculing alleged Chinese claims that the Indians crossed the line and opened fire first".

For the first time in the 15 years of the Global Risks Report, the climate change and environment risk has occupied all the top five slots.

According to the 15th edition of the World Economic Forum's (WEF) Global Risks Report, the top five risks in terms of likelihood are extreme weather, climate action failure, natural disasters, biodiversity loss and human-made environmental disasters. They all fall in the one category of climate change and related environmental disasters.

WEF President Borge Brende said the world was feeling long-mounting and interconnected risks.

The report also points to how citizens are protesting across the world as discontent rises with failed systems that are creating inequality. The citizens' discontent had hardened with systems that had failed to promote advancement, it said.

"Disapproval of how governments are addressing profound economic and social issues has sparked protests throughout the world, potentially weakening the ability of governments to take decisive action should a downturn occur. Without economic and social stability, countries could lack the financial resources, fiscal margin, political capital or social support needed to confront key global risks," it said.

Listing the grim scenario, Borge said the global economy was faced with "synchronised slowdown", the past five years had been the warmest on record and cyber attacks were expected to increase this year.

The report warns that while the myriad risks were rising, time was running out on how to prevent them.

Borge said the growing palpability of shared economic, environmental and societal risks indicated that the horizon had shortened for preventing "or even mitigating" some of the direst consequences of global risks.

"It's sobering that in the face of this development, when the challenges before us demand immediate collective action, fractures within the global community appear to only be widening," he said.

The report points to grave concern about the consequences of continued environmental degradation, including the record pace of species decline.

Pointing to an unsettled geopolitical environment, the report said today's risk landscape was one in which new centres of power and influence were forming and old alliance structures and global institutions were being tested.

"While these changes can create openings for new partnership structures in the immediate term, they are putting stress on systems of coordination and challenging norms around shared responsibility. Unless stakeholders adapt multilateral mechanisms for this turbulent period, the risks that were once on the horizon will continue to arrive," it said.

Calling it a "an unsettled world", the WEF report notes that powerful economic, demographic and technological forces were shaping a new balance of power. "The result is an unsettled geopolitical landscape in which states are increasingly viewing opportunities and challenges through unilateral lenses," it said.

"What were once givens regarding alliance structures and multilateral systems no longer hold as states question the value of long-standing frameworks, adopt more nationalist postures in pursuit of individual agendas and weigh the potential geopolitical consequences of economic decoupling. Beyond the risk of conflict, if stakeholders concentrate on immediate geo-strategic advantage and fail to re-imagine or adapt mechanisms for coordination during this unsettled period, opportunities for action on key priorities may slip away," the WEF said.

In a chapter on risks to economic stability and social cohesion, it said a challenging economic climate might persist this year and members of the multi-stakeholder community saw "economic confrontations" and "domestic political polarisation" as the top risks in 2020.

The report also warned of downward pressure on the global economy from macroeconomic fragilities and financial inequality. These pressures continued to intensify in 2019, increasing the risk of economic stagnation.

Low trade barriers, fiscal prudence and strong global investment, once seen as fundamentals for economic growth, are fraying as leaders advance nationalist policies. The margins for monetary and fiscal stimuli are also narrower than before the 2008-2009 financial crisis, creating uncertainty about how well countercyclical policies will work.

The strategic partners for the WEF report included Marsh & McLennan and Zurich Insurance Group. The academic advisers were National University of Singapore, Oxford Martin School, University of Oxford and Wharton Risk Management and Decision Processes Center, University of Pennsylvania.
