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.

Teachers’ Day: Alli Pledges Teachers’ Welfare Overhaul Within 100 Days

Published

on

 

The governorship candidate of the All Progressives Congress (APC) in Oyo State, Senator Sharafadeen Alli, has promised to place teachers at the centre of his proposed education reforms, with an enhanced welfare package to be introduced within his first 100 days in office if elected.

Alli made the pledge in a goodwill message to teachers in the state ahead of the 2026 World Teachers’ Day celebration.

He said the proposed package would include improved car and housing loans, special rural hardship allowances and a dedicated teachers’ housing and mortgage scheme, particularly for teachers serving in hard-to-staff areas.

The senator also promised to clear backlogs relating to promotions, inter-zonal transfers and secondments through a digital tracking system designed to reduce administrative delays.

According to him, his administration would establish annual State Teachers’ Excellence Awards, with cash prizes, vehicles, laptops and training grants for outstanding teachers.

He added that teachers serving in rural communities would receive special recognition under the proposed award scheme.

Alli further promised to establish a fast-track mechanism for retired teachers’ pensions and gratuities, with clear timelines for addressing outstanding arrears.

On professional development, the APC candidate said teachers would receive continuous training in digital skills, artificial intelligence tools, inclusive education and subject mastery.

He also proposed specialised recruitment and training for special-needs and early-childhood teachers, describing the two areas as important to building an inclusive education system.

On security, Alli promised a comprehensive school security architecture involving perimeter fencing, community security partnerships and rapid-response arrangements.

He said teachers affected by insecurity would also receive support and insurance packages under the proposed scheme.

The APC candidate said school heads would receive timely running grants through a digital accountability system, stressing that teachers should not have to use their personal money to provide basic materials for teaching.

He also promised accelerated renovation of classrooms, provision of furniture and improved water, sanitation and hygiene facilities, with priority given to rural and overcrowded schools.

Alli said his administration would expand access to Information and Communication Technology in public schools through solar-powered laboratories, digital devices and modern teaching tools.

On the challenge of children outside the school system, he pledged to intensify efforts to reduce the estimated 674,000 out-of-school children cited in available state education data through community mobilisation, incentives and public tracking of progress.

The figure has been reported as an estimate from earlier Oyo education data and should not be interpreted as a fresh 2026 headcount.

Alli also proposed an “Oyo Teachers First Compact”, with measurable targets covering teachers’ welfare, security, professional development and learning outcomes.

He said the framework would be implemented in partnership with the Nigeria Union of Teachers and other education unions.

“Our teachers deserve more than applause; they deserve a government that respects their sacrifices, protects their lives, rewards excellence and provides the tools required to teach effectively,” Alli said.

The APC candidate said teachers remained critical to human capital development, adding that education reforms would have limited impact if teachers were neglected or denied the tools and welfare required to perform their duties.

He therefore urged teachers to remain committed to their profession, assuring them that his proposed administration would work with education stakeholders to improve confidence in the state’s education system and learning outcomes.

Teachers Hold Key to Nigeria’s Future – Oseni

Published

Hon. Aderemi Abasi Oseni

The member representing Ibarapa East/Ido Federal Constituency in the House of Representatives and the All Progressives Congress (APC) candidate for Oyo South Senatorial District, Engr. Aderemi Oseni, has described teachers as important builders of the nation, saying their contribution to the development of Nigeria cannot be overemphasised.

Oseni, in a statement on Monday  by his media aide, Idowu Ayodele, to mark this year’s Teachers’ Day, said teachers occupy a special place in society because of the role they play in shaping the minds, character and future of young Nigerians.

He commended teachers for their commitment to the profession despite the challenges confronting the education sector, saying their efforts often go beyond what is seen in the classroom.

According to him, his interventions in the education sector have been guided by the belief that giving children access to a better learning environment is one of the most important investments any government or representative can make.

The lawmaker said his contributions in Ibarapa East/Ido Federal Constituency include the construction of school infrastructure and classroom blocks as well as the provision of furniture, aimed at improving the learning environment for pupils and students.

He said his intervention had also focused on students from less privileged backgrounds, particularly those who could be forced to abandon their educational ambitions because of the cost of examinations and admission processes.

“In line with my commitment to ensuring that no child is left behind due to financial constraints, I have sponsored over 2,000 JAMB forms and more than 1,500 WAEC forms for indigent students. Beyond this, our scholarship and educational support schemes have continued to assist brilliant but underprivileged students at various levels,” the statement said.

The APC chieftain, however, said one of the most rewarding aspects of the intervention was seeing beneficiaries progress through different stages of their education, recalling the case of a beneficiary who had enjoyed consistent support and is expected to become a PhD holder from Obafemi Awolowo University, Ile-Ife, this year.

It continued, “this success story is a source of great joy and motivation. It confirms that consistent investment in education yields lasting results. When we support a student from secondary school through tertiary education and beyond, we are not just changing one life, we are transforming families and communities”.

‎Oseni congratulated teachers on the occasion, assuring them that education would remain a priority in his public service, while calling for greater support for teachers and sustained investment in the sector.

He said every child, irrespective of family background, should have the opportunity to receive quality education and build a better future.

ADC guber candidate, Adegoke decries 674,324 out-of-school children in Oyo

Published

on

The governorship candidate of the African Democratic Congress (ADC) in Oyo State, Chief Adegboyega Adegoke, has expressed concern over the growing number of out-of-school children in the state.

Adegoke raised the concern on Monday in Ibadan, the state capital, while speaking at the inauguration of his campaign council.

He described the situation as worrisome, noting that urgent steps were needed to ensure that children of school age have access to quality education.

Mega Icon Magazine recalled that a recent report indicated that Oyo State has the highest number of out-of-school children in the South-West, with about 674,324 children between the ages of three and 17 reportedly out of school.

Adegoke said it was disturbing that the situation persisted despite the huge federal allocations accruing to the state.

He stressed the need for greater attention to education and grassroots development, saying local government autonomy would help drive human development and economic growth at the grassroots.

“Local government autonomy is a vital tool in grassroots human development and economic growth,” he said.
