Einstein Challenged: Exploring the “Cosmic Glitch” in Gravity – SciTechDaily

Distorted Gravity Art Concept

Researchers propose a modification to Einstein’s theory of general relativity, suggesting a “cosmic glitch” that makes gravity slightly weaker across vast cosmic distances. This adjustment could help explain some unaccounted phenomena in the universe. Credit: SciTechDaily.com

For the last 100 years, physicists have relied upon Albert Einstein’s theory of “general relativity” to explain how gravity works throughout the universe. General relativity, proven accurate by countless tests and observations, suggests that gravity impacts not simply three physical dimensions but also a fourth dimension: time.

Challenges at Cosmic Scale

“But when we try to understand gravity on a cosmic scale, at the scale of galaxy clusters and beyond, we encounter apparent inconsistencies with the predictions of general relativity. It’s almost as if gravity itself stops perfectly matching Einstein’s theory. We are calling this inconsistency a ‘cosmic glitch’: gravity becomes around one percent weaker when dealing with distances in the billions of light years. “

For more than twenty years, physicists and astronomers have been trying to create a mathematical model that explains the apparent inconsistencies of the theory of general relativity. Many of those efforts have taken place at Waterloo, which has a long history of cutting-edge gravitational research resulting from ongoing interdisciplinary collaboration between applied mathematicians and astrophysicists.

Historical Context and Research Efforts

“Almost a century ago, astronomers discovered that our universe is expanding,” said Niayesh Afshordi, a professor of astrophysics at the University of Waterloo and researcher at the Perimeter Institute.

“The farther away galaxies are, the faster they are moving, to the point that they seem to be moving at nearly the speed of light, the maximum allowed by Einstein’s theory. Our finding suggests that, on those very scales, Einstein’s theory may also be insufficient.”

Modifying Einstein’s Theory

The research team’s new model of a “cosmic glitch” modifies and extends Einstein’s mathematical formulas in a way that resolves the inconsistency of some of the cosmological measurements without affecting existing successful uses of general relativity.

“Think of it as being like a footnote to Einstein’s theory,” Wen said. “Once you reach a cosmic scale, terms and conditions apply.”

“This new model might just be the first clue in a cosmic puzzle we are starting to solve across space and time,” Afshordi said.

The study, “A cosmic glitch in gravity,” appears in the Journal of Cosmology and Astroparticle Physics.

Fallout fever hits Fortnite, Epic Games drops clues – Hindustan Times

May 18, 2024 09:20 AM IST

Epic Games teases fans with a Fallout-themed costume but no release date.

The buildup and tidbits have been all over the place lately, spilling the beans that Fallout would be in Fortnite, thus confirming a rumour about a collaboration between Epic’s Battle Royale and the iconic RPG from Bethesda. However, the discussion of a collab in the Twitter Space between them both has been on the lips of fans since the premiering of the Fallout TV show produced by Amazon Prime last month.

The specifics of what this collab will bring to the Fortnite universe remain shrouded in mystery.

Epic Games has kept a tight lip on the details. Usually, such collaborations have brought a plethora of themed goodies to Fortnite’s virtual shelves, including player skins, back blings, weapon skins, and emotes, all inspired by the collaborating franchise and available for purchase in the game’s item shop.

Fortnite’s official X (formerly Twitter) account released something to please the community itching for more today. It can be clearly seen that the costume not only includes the famous power armour of Fallout but also includes an impressive industrial landscape in the background. The post teased fans but still declined to provide an actual release date by simply including two emojis-a winking face and a thumbs up- in the caption line. This has always been our go-to gesture to pay tribute to Vault Boy, the mascot that has been cherished by the fans for decades.

What will Fallout X Fortnite look like?

Several gamers are wondering which Fallout series Epic Games will feature, or they will just take a nod from the live-action series.

Despite the flurry of inquiries, Epic Games has remained silent. Fallout 76, the franchise’s latest entry, is considered an unlikely muse due to its polarizing reception, which leaves Fallout 4 as a probable source of inspiration.

Yet, it’s entirely feasible that the collaboration will draw from the rich tapestry of the entire Fallout universe, cherry-picking fan-favourite elements to incorporate into Fortnite’s offerings. This approach wouldn’t be unprecedented; Epic has previously curated cosmetic bundles from franchises like Family Guy and Resident Evil, blending various elements from different iterations within those series.

LSU student moves to eliminate socio-economic challenges – NewsDay

Bongani Tshuma said the socio-economic challenges faced in the village are the root causes of the problems faced by the youths.

A LUPANE State University (LSU) student who was struggling to pay fees has made waves in Khafa village under Chief Madhliwa, in Nkayi, Matabeleland North province with his project to eliminate the crippling socio-economic challenges faced by the youth.

After getting help from well-wishers, Bongani Tshuma, a second-year applied biotechnology student has formed an organisation aimed at offering free online lessons to students and mentorship programmes to the youth in Nkayi.

He formed the organisation called Zim Inclusive Leaning Trust with his colleague Melulwazi Dlamini.

“Professional life coaches and teachers volunteer to teach for free, we have managed to reach many students and also got sponsors to help a few academically gifted students. We want to expand the number of students to get sponsorship so that they attend school. As the representative of Nkayi in the organisation, I am working very hard to see our youths in Nkayi doing great,” Tshuma told Southern Eye.

This latest development comes after Tshuma observed, through his research, that people from his village were battling with early marriages, child pregnancies, school dropouts, high crime rates and other related social issues in the community.

Tshuma said the socio-economic challenges faced in the village are the root causes of the problems faced by the youths.

“Nkayi is grappling with persistent social and economic challenges, including early pregnancies and a high crime rate, which can be attributed to limited access to secondary education,” Tshuma said.

“The schools are approximately 12km away, forcing students to walk long distances, resulting in a high dropout rate. In fact, fewer than 3% of students have passed their O’ Levels in the past five years.”

He also observed that boys abandon their education to work as illegal miners, which ultimately harms the community with the police not adequately addressing the issues that arise.

“We have underprivileged learners in Nkayi who are academically gifted but they don’t get access to education,” he said.

Tshuma pleaded with the government to address these challenges by increasing the number of secondary schools in the area.

“We also seek assistance from individuals in the diaspora to invest in our community; introducing manual work programmes can help reduce youth unemployment,” he said.

“We must prioritise affordable education for every girl child in our community, many dropouts occur because parents or guardians are unable to fund school fees. We advocate a law that targets support for girls in rural areas and holds culprits accountable for their actions. We need stricter law enforcement to address the issues in our villages.”

Mangwe villagers fight devastating drought – The Southern Eye – NewsDay

The communities since November last year have been receiving US$54 where some have been able to do projects and generated more income.

VILLAGERS in ward 3 of Madabe village, Plumtree in Mangwe District, Matabeleland South, are grappling with the devastating effects of a severe drought induced by climate change, but have taken it on themselves to survive.

Despite the challenges, the villagers persevered thanks to the emergency social cash transfer (ESCT) programme introduced by  the government and Unicef, which has enabled them to sustain themselves through various home projects.

While they continue to navigate the challenging recovery process, the communities are, however, calling on the government to maintain the crucial support provided by the ESCT, emphasising its vital role in their ongoing survival and resilience.

Under the ESCT programme, vulnerable families get monthly payments to alleviate poverty.

Goal Zimbabwe are the implementing partners with financial support from the Government of Germany through their KfW Development Bank.

The communities since November last year have been receiving US$54 where some have been able to do projects and generated more income.

A beneficiary from the programme, Mkhumbulo Mpofu (66), said the project came at a time when the area had been hit by drought.

“This programme has helped the community we had nothing at all. We last received the rains the past two years and we have been hit by severe drought. But through the introduction of this programme, we have managed to start up different projects.

“I have managed to pay school fees for my grandchildren, buy uniforms and food at home. This is a good initiative and we don’t want it to end. As you can see I am an old man and now it’s difficult for me to fend for the family,” he said.

Mpofu added: “We had nothing but then with this help from Goal, it has brought a little hope otherwise we would be dead by now. I am happy and appreciate this programme.

Sipho Moyo (57) said the programme had assisted her including taking care of her grandchildren.

“This programme started in November and the funds have helped me and my family because I was in a crisis.”

“But then after, I saw a change. I am able to get something which I can give to my grandchildren. I have my grandchild who is at high school, this money has helped me pay fees.

“Even our life has changed a bit because things seem to be going on well for me. I took the other money and invested in a club. We are contributing US$10 a month and that money we are able to lend it to a member who repays inclusive of an interest of 10%. Goal really helped me with my family.”

The ESCT helps provide support to families to deal with reduced income and scarcity of access to water and food. Cash transfer positively impacts household’s ability to ensure continued education of their children and feed their children.
