Gate Of Hell Shown By Scientists – ‘Black Hole’
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.
The Nigeria Union of Teachers (NUT), Oyo State Wing, has directed all public primary and secondary school teachers in the state to embark on an indefinite strike over the continued abduction of teachers and pupils.
The strike, which takes effect from Monday, June 1, 2026, is expected to ground academic activities across public schools in the state.
The union said the action became imperative following what it described as growing insecurity in schools and the prolonged captivity of abducted teachers and pupils whose whereabouts remain unknown.
In a statement jointly signed by the Chairman of the Oyo State Wing of the NUT, Hassan Fatai, and the Secretary, Salami Olukayode, the union expressed concerns over the psychological impact of the incidents on teachers, learners and parents.
According to the union, the lingering abduction cases have created fear and anxiety among teachers, weakened confidence in the safety of schools and discouraged many parents from sending their children to school.
The statement read in part, “The Nigeria Union of Teachers, Oyo State Wing, hereby directs all public primary and secondary school teachers across the state to commence an indefinite strike action effective from Monday, June 1, 2026, pending urgent and decisive action by relevant authorities on the abduction of teachers and pupils.”
The union explained that the industrial action was aimed at compelling the government and security agencies to intensify efforts toward the immediate and unconditional release of the victims.
It urged teachers across the state to comply fully with the directive, remain peaceful and law-abiding, and prioritise their safety while staying away from classrooms during the strike.
The NUT also expressed solidarity with the abducted victims and their families, assuring that it would continue to engage relevant authorities until the victims were safely rescued.
The union reaffirmed its commitment to the welfare, safety and security of teachers and pupils, stressing that the protection of school communities remained non-negotiable.
No fewer than 2,243,816 candidates on Thursday commenced the 2026 Unified Tertiary Matriculation Examination conducted by the Joint Admissions and Matriculation Board across accredited Computer-Based Test centres nationwide.
The figure represents a 10.5 per cent increase from the 2.03 million candidates recorded in 2025.
The examination, which began on April 16, is being conducted in about 1,000 CBT centres nationwide, with candidates scheduled in four daily sessions to reduce congestion and improve verification processes.
The board said it had deployed biometric verification and real-time monitoring systems to safeguard the integrity of the exercise, noting that candidates whose biometric details could not be authenticated would be rescheduled.
Candidates were advised to print their examination slips from the JAMB portal to confirm their schedules and arrive at least one hour before their examination time.
Under the revised timetable, first-session candidates are expected at 7:00 a.m., followed by 9:00 a.m. for the second session, 11:00 a.m. for the third session, and 2:00 p.m. for the final session.
JAMB disclosed that Lagos State recorded the highest number of registered candidates with 381,814, followed by Ogun with 137,156 and Oyo with 122,662. Kaduna recorded 103,498 candidates, while the Federal Capital Territory had 102,961.
Other states include Rivers with 105,584 candidates and Kano with 83,167, while Borno and Zamfara recorded the lowest figures with 13,483 and 14,861 candidates respectively.
Outside Nigeria, participation remained low, with Côte d’Ivoire recording 32 candidates, followed by Equatorial Guinea with 16, Burkina Faso with 14, and the United Kingdom with 12 candidates.
As part of efforts to enhance efficiency, the board increased the number of CBT centres but delisted 23 centres across several states, including Lagos, Ogun, Oyo, Delta, Edo, Plateau and the Federal Capital Territory, over technical deficiencies observed during the mock examination.
The board said the action was necessary to maintain operational standards and ensure the credibility of the examination process.
Meanwhile, the Nigeria Police Force dismissed reports of insecurity at some centres, describing such claims as unfounded.
The police said it had deployed additional personnel, including patrol teams, perimeter surveillance units and rapid response squads, to ensure the safety of candidates nationwide.
The force added that it was collaborating with other security agencies to monitor the exercise and respond swiftly to any threats.
It assured parents and candidates of adequate security, urging candidates to comply with examination guidelines, arrive early and report suspicious activities.
The police also advised the public to disregard unverified information on social media and rely on official communication channels.
JAMB reiterated its commitment to transparency, warning candidates against accepting admissions outside its Central Admissions Processing System.
It stressed that any admission conducted outside CAPS would be considered illegal and would not be recognised.
The Joint Admissions and Matriculation Board has delisted 23 Computer-Based Test centres nationwide following technical deficiencies recorded during the 2026 mock Unified Tertiary Matriculation Examination.
The Board disclosed this in a bulletin issued on Friday and signed by its Public Communication Advisor, Fabian Benjamin, as preparations intensify for the 2026 UTME scheduled to hold across the country from April 16 to April 25.
According to JAMB, the mock examination was designed to assess operational readiness and identify centres that failed to meet the required technical standards.
“Following the conduct of the 2026 Mock Unified Tertiary Matriculation Examination, the Board has delisted 23 Computer-Based Test centres for technical deficiencies,” the statement read.
The Board added that several centres with minor issues had been placed on notice, warning that continued non-compliance could lead to further sanctions. It also stated that one centre would no longer be used for any of its examinations.
JAMB disclosed that a total of 2,243,816 candidates registered for the 2026 UTME, with Lagos recording 321,814 candidates, Kaduna 303,498, the Federal Capital Territory 302,963, and Ogun 137,156.
To improve accessibility and logistics, the Board said it increased the number of approved examination centres to 1,000 nationwide, up from fewer than 800 in 2025.
However, an internal review conducted after the mock exercise revealed that some centres failed to meet operational and technical benchmarks, prompting their removal from the approved list.
The delisting followed reports of widespread technical glitches during the mock examination, including network failures, system malfunctions and delayed commencement of tests in several locations. Some candidates and parents also complained about hours-long waiting periods at affected centres.
The affected centres are located in Abia, Anambra, Bayelsa, Delta, Edo, the Federal Capital Territory, Lagos, Ogun, Osun, Oyo and Plateau states.
Among the delisted centres are Micben Seat of Wisdom Academy, Ukwa West, Abia; Bishop Crowther Seminary CBT Centre, Awka, and The Oracle Lens, Nnokwa, Anambra; Derby’s Young ICT Centre, Yenagoa, Bayelsa; Avid ICT Solutions CBT Centre, Asaba, Delta; and Daniet Global Resources CBT Centre, Benin City, Edo.
Others include De-Lite CBT Centre, Maitama, Abuja; Florin High School CBT Centre, Ejigbo; Folbob CBT Centre, Lakowe; Great Kezino College CBT Centre, Ikorodu; Obans CBT Centre, Ikorodu; and Teesas Learning and CBT Centre, Lekki, all in Lagos.
Also affected are Braingate Model Schools CBT Centre, Arepo, and Greenhills Academy CBT Centre, Itele, Ogun State; Oduduwa University CBT Centre, Ile-Ife, Osun State; Lasting Glory Schools CBT Centre, Ibadan; Nesam International School CBT Centre, Ibadan; SAF Polytechnic CBT Centre, Iseyin, Oyo State; and Rabjib Computer Academy, Jos, Plateau State.
JAMB stated that the decision formed part of efforts to safeguard the integrity of its examination process and ensure that only centres that meet its operational requirements are used for the main UTME.
The Board assured candidates that necessary measures had been put in place to ensure a smooth conduct of the examination nationwide.
