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.

UI’s 545th inaugural lecture: Pogoson urges Tinubu to review foreign policy amid global shifts

Published

Professor Aituaje Irene Pogoson, a scholar at the University of Ibadan (UI), has emphasised the pressing need for a more coherent elucidation of President Bola Tinubu’s 4-D renewed foreign policy doctrine.

This assertion was made during her delivery of the university’s 545th inaugural lecture entitled “The World in Transition: Understanding Power in the International System.”

Addressing a diverse audience including prominent academics and former Vice-Chancellors, Professor Pogoson underscored the imperative for Nigeria to confront a myriad of socio-economic and political challenges to assert its position in the evolving global landscape.

The lecture, marking the 14th in the series for the 2022/2023 academic session and the 11th inaugural lecture from the Department of Political Science, highlighted the urgency for Nigeria to recalibrate its foreign policy strategy.

Speaking passionately, Professor Pogoson, the first female lecturer and Head of the Department of Political Science at the university, lamented Nigeria’s current positioning within the global order, stressing the need for the country to maintain respect and relevance internationally.

She emphasised the necessity for Nigeria to re-strategize and re-formulate its foreign policy framework to effectively address both internal and external dynamics.

In analysing President Tinubu’s administration’s efforts towards repositioning Nigeria on the global stage, Professor Pogoson acknowledged the unveiling of ‘Nigeria’s 4-D Renewed Foreign Policy Doctrine,’ comprising Democracy, Demography, Development, and Diaspora.

However, she urged for a clearer articulation of this doctrine, advocating for concrete policies and actions to be outlined.

This marked Professor Pogoson’s third public lecture at the university, following her previous engagements addressing issues ranging from terrorism and national security to global power shifts.

President Bola Tinubu marked a significant milestone on Wednesday as he officially signed the National Students Loan Amendment bill into law during a brief ceremony held at the State House.

The event witnessed the presence of esteemed dignitaries including Senate President Godswill Akpabio, Deputy President of the Senate Barau Jibrin, Chief of Staff to the President Femi Gbajabiamila, Ministers Hannatu Musawa and Ayodele Olawande, as well as the president of the National Association of Nigerian Students, alongside other government officials and presidential aides.

The bill, initially endorsed by Tinubu in June 2023, aims to provide crucial financial assistance to Nigerian students pursuing tertiary education. Despite its previous signing, the implementation of the bill encountered delays attributed to various challenges hindering its rollout.

In his remarks following the signing, President Tinubu expressed gratitude to the National Assembly for their swift handling of the bill, emphasising the pivotal role of education in combating poverty.

He stated, “First of all, I must thank members of the National Assembly for their expeditious handling of this bill considering the children of Nigeria, that education is the tool to fight against poverty effectively.”

Tinubu reiterated the government’s commitment to prioritising education and fostering skills development programmes to ensure equitable access to quality education for all Nigerian citizens, regardless of their socio-economic backgrounds.

He underscored the importance of eliminating barriers to education, stating, “We are determined to ensure that education is given the proper attention necessary for the country including skills development programmes. This is to ensure that no one, no matter how poor their background is, is excluded from quality education and opportunity to build their future.”

Highlighting the significance of the bill, Tinubu emphasised the transformative impact it will have on addressing the issue of college dropout rates among Nigerian students.

He affirmed, “We are here because we are all educated and were helped. In the past, we have seen a lot of our children drop out of college and give up the opportunity. That is no more, the standard and the control is there for you to apply no matter who you are as long as you are a Nigerian citizen.”
