Gate Of Hell Shown By Scientists – ‘Black Hole’

Published

on

What was earlier tagged – ‘Science fiction has now become science fact’ as an international scientific team, having used  a global network of telescopes to see ‘the unseeable’ on Wednesday announced another feat in astrophysics – the first-ever photo of a black hole – an achievement that upheld a pillar of science put forward by Albert Einstein.
 
Black hole was first propounded theoretically by a German-born theoretical physicist, Albert  Einstein more than 100 years ago, now proven experimentally.
 
 
What is a black hole? 
It is a place with such gravitational pull that nothing can escape including light. Black holes are monstrous celestial entities exerting gravitational fields so vicious that no matter or light can escape. The somewhat fuzzy photo of the black hole at the center of Messier 87, or M87, a massive galaxy residing in the center of the relatively nearby Virgo galaxy cluster, reveals a glowing ring of red, yellow and white surrounding a dark center.

Interestingly, the research which was conducted by the Event Horizon Telescope (EHT) project, an international participation involving about 200 scientists begun in 2012 to try to directly observe the immediate environment of a black hole and its announcement was made in simultaneous news conferences in Washington, Brussels, Santiago, Shanghai, Taipei and Tokyo respectively.

The image, as reliably learnt,  was obtained using data collected in April 2017 from eight radio telescopes in six locations that essentially create a planet-sized observational dish.

The team’s observations strongly proved the theory of general relativity proposed in 1915 by Einstein, the celebrated  theoretical physicist, to explain the laws of gravity and their relation to other natural forces.

According to astrophysicist Sheperd Doeleman, director of the Event Horizon Telescope at the Center for Astrophysics (CfA), Harvard & Smithsonian, “We have achieved something presumed to be impossible just a generation ago”.

Black holes, phenomenally dense and coming in various sizes, are extraordinarily difficult to observe by their very nature. A black hole’s event horizon is the point of no return beyond which anything – stars, planets, gas, dust and all forms of electromagnetic radiation – gets swallowed into oblivion.

The M87 black hole observed by the scientific team resides about 54 million light-years from Earth and boasts an almost-unimaginable mass of 6.5 billion times that of the sun. A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).

“This is a huge day in astrophysics. We’re seeing the unseeable. It did bring tears to my eyes”,  U.S. National Science Foundation Director, France Cordova submitted.

The existence of black holes was first predicted in 1916. Most galaxies are thought to have a supermassive black hole at their center.

Meanwhile, the fact that black holes do not allow light to escape makes viewing them difficult, thus the scientists looked for a ring of light – super-heated disrupted matter and radiation circling at tremendous speed at the edge of the event horizon – around a region of darkness representing the actual black hole. This is known as the black hole’s shadow or silhouette.

The scientists further confirmed that Einstein’s theory correctly predicted that the shape of the shadow would be almost a perfect circle. With M87, it deviated from perfect circularity by less than 10 percent.

Remarking, astrophysicist Dimitrios Psaltis of the University of Arizona, the EHT project scientist said, “we found literally the proverbial hole in the middle of this galaxy, and to me that is just stunning”.

Einstein’s theory also was validated by another major astrophysics achievement announced in 2016, the detection of gravitational waves, or ripples in spacetime, arising from two black holes that smashed together.

“Science fiction has become science fact,” University of Arizona astronomy professor Daniel Marrone emphasized.

“The image has this exquisite beauty in its simplicity,” said another CfA astrophysicist Michael Johnson, the project’s imaging coordinator.

 “It is just a fundamental statement about nature. It’s a really moving demonstration of just what humanity is capable of”, he added.

By

 

The West African Examinations Council (WAEC) has announced the commencement of its Computer-Based West African Senior School Certificate Examination (CBWASSCE) for private candidates, starting from October 25, 2024.

The examination is set to run until December 20, 2024, according to a statement released by the council on Tuesday.

In a bid to modernise the examination process, WAEC disclosed that the CBWASSCE will be conducted in a hybrid format.

Adesina Fadekemi, the council’s spokesperson, explained that the objective or multiple-choice questions would be displayed onscreen, requiring candidates to submit their responses electronically.

However, for essay and practical questions, while the questions will also be presented digitally, candidates will still provide answers using traditional answer booklets.

Additionally, WAEC has provided an option for candidates who prefer to use the conventional Paper and Pen mode for all exam papers, catering to those not comfortable with the digital format.

The council also extended the registration deadline for the upcoming CBWASSCE to Tuesday, October 29, 2024.

Candidates who miss the registration window can still take advantage of the “Walk-in-Candidate” option, allowing them to register 24 hours before their preferred paper is scheduled.

The Chairman of the Senate Committee on Environment and Senator representing Oyo Central Senatorial District, Dr. Yunus Akintunde, has reaffirmed his commitment to aiding the Federal Polytechnic Ayede in realising its full potential.

Senator Akintunde made this pledge during a courtesy visit to the institution’s temporary site in Iresa-Pupa, Ogbomoso, on Wednesday.

Speaking during the visit, the lawmaker highlighted his passion for contributing to humanity, especially through the advancement of education and skills development.

“I am part of the polytechnic system. I started at The Polytechnic, Ibadan before going to Lagos State University, Ojoo, Lagos. I’m a lover of knowledge and I am always striving to contribute my quota in the area of education and skills development, among others, and in the legislative assignments as my primary responsibility,” he stated.

The APC chieftain further emphasised his dedication to supporting the Polytechnic and its community, stating that leaders should be driven by a commitment to serving humanity.

He cited the legacy of Hon. Olu Afolabi, a Second Republic House of Representatives member, who was instrumental in establishing the Federal College of Education (Special), Oyo.

“Afolabi’s legacy remains evergreen today,” Akintunde remarked, emphasising the importance of creating lasting impacts through public service.

As part of his developmental projects for the Oyo Central Senatorial District, Akintunde disclosed that he had procured 120 solar-powered boreholes to be installed across the 118 wards of the 11 local governments in his senatorial district, along with 10,000 solar street lights.

He assured the Federal Polytechnic Ayede that some of these solar street lights would be installed within the institution to enhance security and visibility on campus.

Earlier, the Rector of the Federal Polytechnic Ayede, Dr. Taofeek Abdul-Hameed, who was represented by the acting Rector and Deputy Rector (Academics), Mr. Azeez Ojo, expressed gratitude to the senator.

The Rector noted that Senator Akintunde had demonstrated a deep commitment to philanthropic causes even before assuming office as a senator.

“You see, it’s a great privilege receiving Distinguished Senator Yunus Akintunde and his entourage on our campus today. Out of your magnanimity, Sir, you have decided to receive us,” Ojo said, acknowledging the senator’s gesture.

“Our Rector is away to Abuja for the progress and development of our Polytechnic. So, on behalf of the Chairman of our Governing Council, Barrister Ademubowale Mercy Adelabu; Rector; other Principal Officers; Deans; Directors; staff, and students, I welcome you and your entourage to Federal Polytechnic Ayede.

“While on Brave FM, you have, before even telling us, announced the gesture of solar lights donated to us. This we appreciate with the whole of our hearts,” he said.

Mass Exodus: 30 PhD Holders Flee Bauchi Varsity Amid ASUU’s Alarm on Poor Conditions

Published

on

By

The Academic Staff Union of Universities (ASUU), Bauchi Zone, has raised serious concerns over the mass exit of 30 PhD holders from Sa’adu Zungur University (SAZU), formerly known as Bauchi State University, citing deteriorating working conditions and inadequate welfare provisions as primary reasons for the exodus.

The worrying development was brought to light during a press conference held by ASUU on Friday, where officials of the union detailed the various challenges faced by academic staff at the institution.

Speaking on behalf of the union, Zonal Coordinator of ASUU Bauchi Zone, Namo Timothy, lamented the lack of proper policies to retain top scholars, pointing out the absence of a formal employee exit policy.

“Many of our best scholars have been forced to seek better opportunities elsewhere,” Timothy said, adding that “SAZU has no pension or death benefit scheme in place, as obtained in the structured public service regulation in the country.”

He further explained that the lack of such provisions leaves academic staff insecure about their future. “Without a pension or death benefit scheme, our members feel unsafe and unsure of their long-term prospects,” Timothy remarked.

In addition to these grievances, the union condemned the university’s administration for its failure to pay over 650 million naira in accumulated entitlements, including earned academic allowances and honorariums for internal examiners. This has further deepened the discontent among staff members.

“Despite the university generating significant revenue from postgraduate programs, our members have not been compensated for their contributions,” Timothy disclosed.

The union also raised concerns over the sharp increase in student fees, coupled with the administration’s neglect of staff training and development.

Timothy criticised the university for imposing over a 100 percent hike in fees for regular undergraduate programmes, yet failing to address staff welfare.

“The university claims it lacks funds to pay our members, yet it continues to impose higher charges on students,” he stated.

ASUU also expressed displeasure with the continued tenure of the current Pro-Chancellor, who has remained in office since the university’s inception.

The union called for adherence to established regulations governing appointments, arguing that the prolonged tenure has stifled accountability and hindered the implementation of progressive policies.

In light of these critical issues, ASUU urged the Bauchi State Government and other stakeholders to take immediate action to address staff welfare, calling for the establishment of a comprehensive exit policy and the payment of overdue allowances.

“Unless these issues are resolved, we cannot guarantee industrial harmony within SAZU,” Timothy warned.

He further called on the state government to declare a state of emergency at the university to ensure that all contentious matters are urgently addressed, securing the future of both academic staff and the institution.
