Backflipping down a steep and sandy mountainside, Afghan teenager Imran Saeedi wows the crowds of men who gather each springtime to unwind beside breathtaking views.

Hundreds of visitors travel each weekend to Reg-e-Rawan -- "the moving sands" in Dari -- to practice parkour or roll down the honey-colored sand in Kapisa province.

"I feel afraid when I'm going for a flip or a jump, and of course I can get injured," said 16-year-old Saeedi, who nonetheless loves the thrill.

"When the week starts, I'm just waiting for the weekend so I can come to Reg-e-Rawan to have fun again," said the high school student.

Men and boys clapped in admiration as he ran down the hill and flipped forwards, then backwards, while his friends filmed on their phones.

Less daring onlookers sat atop rocks surrounding the mountain, picnicking together and enjoying the scenery.

Reg-e-Rawan is off limits to women and girls, who are banned by the Taliban authorities from recreational spots such as parks.

Families with women were turned away when AFP journalists visited, while officials under the Ministry for the Propagation of Virtue and the Prevention of Vice patrolled the area.

- 'Humans need nature' -

Mirwais Kamran, a 48-year-old businessman, had driven three hours north from the capital Kabul with some of his 12 children.

"I feel joy when I come here with my children and friends," said Kamran, who climbed up the slope but stopped short of rolling down.

Nusratullah Nusrat, the provincial head of tourism at the Kapisa Department of Information and Culture, said the site dates back thousands of years.

"The unique feature of this place is that the sand never decreases despite people climbing up and sliding down," he told AFP.

Some people believe rolling in the sand also helps treat rheumatism, added Nusrat.

For visitors such as Nohzatullah Ahmadzai, who travelled from Kabul with a group of friends, Reg-e-Rawan lifts his mood.

"I'm someone who gets depressed when I'm sad, so visiting such places erases that feeling," said the 22-year-old, who works for a cargo firm.

Climbing the slope takes about an hour, rewarding visitors with views over green fields dotted with villages.

"We humans need nature," said Ahmadzai. "When we feel stressed, we can visit natural places for relaxation or relief."

Scientists have detected the "fingerprints" of a black hole's event horizon -- the boundary from which nothing can escape -- for the first time, according to research published on Wednesday.

The discovery was made by studying ripples in space-time called gravitational waves that were created when two black holes violently smashed into each other.

A black hole's event horizon is known as the "point of no return" because not even light can avoid being swallowed into its darkness.

This has made them incredibly difficult to learn anything about.

However, there is one event of such cataclysmic violence that it could offer a chance to glimpse this extreme phenomenon -- when two black holes merge into one.

When this cosmic death spiral occurs, it shoots gravitational waves across the universe which scientists have been detecting for the last decade.

For the new research published in Nature, an international team of researchers analyzed data from the strongest gravitational wave ever recorded, known as GW250114, detected by the LIGO observatory in January 2025.

By isolating the last burst of waves -- known as "direct waves" -- from this black hole merger, the scientists said they were able to extract information from closer to an event horizon than ever before.

"This black hole horizon concept normally appears in science fiction," lead study author Sizheng Ma of the Perimeter Institute for Theoretical Physics in Canada told AFP.

"But now we are really able to touch the region around the horizon with gravitational data," he added.

"Sometimes I cannot believe this is really happening."

- Causing a stir -

The last stage of two black holes merging is like a spoon stirring a glass of water, Sizheng Ma explained.

The resulting swirl in space creates the ripple of gravitational waves that travel at the speed of light in all directions.

If the metaphorical spoon is stirring close enough to the black hole's event horizon, "this offers us a chance to decode the physics around that region", Sizheng Ma said.

By supporting the theory of general relativity, the results "proved that Einstein was correct again," he added.

The scientists emphasized that more research was needed to decipher what can be gleaned about event horizons using this method.

But they did detect information about how black holes twist space around themselves as they rotate -- a phenomenon known as "frame dragging".

"This is similar to pushing a glass into a table and twisting it, so that the tablecloth winds up around it," Maximiliano Isi, a gravitational wave astrophysicist at Columbia University, told AFP.

In the future, the team of scientists hope to find signs of tiny changes known as quantum fluctuation.

"In this way, we can really probe this near horizon region to look for a new physics," including searching for a deviation from general relativity, Sizheng Ma said.

- Reaction mixed -

Experts not involved in the study urged caution.

Francesco Sannino, an Italian theoretical physicist who studies black holes, told AFP it was "compelling analysis" but needed to be checked by other researchers.

Still, it was "striking" that the scientists were able to show that gravitational waves carried the event horizon's "fingerprints," he said.

The astrophysicist Isi described the work as "tantalizing".

"More generally, understanding the physics of black holes and their mergers is important as it might shed light on how space and time are woven together at a more fundamental level," he told AFP.

Sean McWilliams, an astrophysicist at West Virginia University, was skeptical that the gravitational wave frequency analyzed by the scientists was actually "dictated" by the event horizon.

For this reason, "the actual observed signal doesn't really tell us anything about the horizon or the other properties directly related to it", he told AFP.

Sizheng Ma said McWilliams's statement was "not correct," suggesting he had conflated two different aspects in the paper.

"There is often considerable resistance and criticism in the early stages of promoting a new concept," he said, adding he is working on another paper to "clarify these confusions and possible misinterpretations".

A large asteroid that will zoom harmlessly past Earth on Saturday will be visible to stargazers using a small telescope or large binoculars, the European Space Agency announced Wednesday.

The asteroid will come within 2,560,000 kilometers of Earth at 1114 GMT on Saturday, which is more than six times the distance between the Earth and the Moon.

Called (152637) 1997 NC1, the asteroid will be speeding along at nearly nine kilometers a second, posing no threat to Earth as any chance of an impact has been ruled out.

Discovered in 1997, the asteroid is estimated to be between 750 and 1,650 meters wide, according to calculations based on how much sunlight it reflects.

However other estimates suggest it could be smaller, AFP quoted the ESA as saying in a statement.

"A close approach to Earth by an object this size only occurs every few years, although this time the bright nearby Moon might impede its observability at closest approach," Juan Luis Cano of the ESA's Planetary Defense Office said in a statement.

For stargazers with telescopes or binoculars, the asteroid will be visible in parts of the Northern Hemisphere as it approaches, almost everywhere as it speeds past Earth, and only from the Southern Hemisphere as it departs.

But this depends if people are in areas of the world where the sky is dark enough as it passes.

Singapore, Indonesia, Malaysia and Brunei face a high risk of severe haze this year due to hot and dry weather conditions, biofuel demand and economic pressures, a research institute said Wednesday.

The Singapore Institute of International Affairs said it was the second time it had issued a red risk rating since launching its Haze Outlook report in 2019. The previous red risk rating was in ⁠2023, Reuters reported.

Here are some ⁠details:

August to September is the peak danger period for haze in the Southeast Asian region, driven by the El Niño and Indian Ocean Dipole weather phenomena, the report said.

The ⁠return of El Niño is expected to create a longer and stronger dry season at a time when fire preparedness could be adversely affected by economic uncertainty and cost pressures.

The SIIA said rising costs of fertilizer and fuel as a result of the Iran war could lead to unsustainable activity such as the use ⁠of ⁠fire rather than machinery to clear land and dispose of waste.

Land use could also intensify as demand for biofuels rises due to energy supply disruptions.

"This trend will continue even if the US-Iran agreement holds, as countries now want energy independence," said SIIA associate director Khor Yu-Leng.

ASEAN cooperation and sustainable land management will be critical to reducing risks, the report said.
