Three American physicists Rainer Weiss, Barry Barish and Kip Thorne on Tuesday won the Nobel Prize in Physics for discovering the gravitational waves, ripples in the fabric of spacetime, a phenomenon anticipated by Albert Einstein a century ago.

Gravitational waves are extremely faint ripples in the fabric of space and time, generated by some of the most violent events in the universe.

The Royal Swedish Academy of Sciences in Stockholm announced that Rainer Weiss will be awarded one half of the 9m Swedish kronor (£825,000) prize, whereas  Kip Thorne and Barry Barish will share the other half of the prize.

The credit for discovering the gravitational waves will go to all three scientists who led the Laser Interferometer Gravitational-Wave Observatory, or Ligo, experiment, which enabled them to observe gravitational waves in September 2015.

Weiss, emeritus professor of physics at Massachusetts Institute of Technology is an experimentalist who made major contribution in the concept design, funding and the construction of the observatory.

Kip Thorne, who is the professor of theoretical physics at California Institute of Technology made crucial predictions of how to identify the gravitational wave and how it would look.

Barry Barish,  a former particle physicist at California Institute of Technology (now emeritus professor) is credited for getting the experiment off the ground. The scientist saw the project through – it was in danger of being cancelled when he took over as the second director of Ligo in 1994.

Ronald Drever, a Scottish physicist, who alongside Weiss and Thorne played a leading role in developing Ligo, died in March from dementia less than 18 months after gravitational waves were first detected. The Nobel prize is not normally awarded posthumously.

The Ligo is designed to detect a distortion of a thousandth of the diameter of an atomic nucleus across a 4 Km length of laser beam. The phenomenon detected was the collision of two black holes. With the most sophisticated detector, the scientists listened for 20 thousandths of a second as the two giant black holes, one 35 times the mass of the sun, the other slightly smaller, circled around each other. The two objects had begun by circling each other 30 times a second. By the end of the 20 millisecond snatch of data, the two had accelerated to 250 times a second before the final collision and a dark, violent merger.

Nobel Prize was first awarded in 1901 for achievements in science, literature and peace, in accordance to the will left by Swedish business tycoon Alfred Nobel who had bequeathed much of the fortune he generated from his discovery of dynamite.

Among the science prizes, physics has often taken centre stage with laureates including scientific superstars such as Einstein, Niels Bohr and Marie Curie, one of only two women to win a Nobel Prize for Physics.[/vc_column_text][/vc_column][/vc_row]

Google shared a doodle today to celebrate World Earth Day 2024, which showcased aerial photos of the planet’s biodiversity and natural beauty. Google reminded us of the importance of protecting planet earth for future generations with the help of this doodle.

The Google letters depict specific locations across the globe where people, communities, and governments work every day to help protect the planet’s natural beauty, biodiversity, and resources, according to the explanation of the annual Earth Day 2024 doodle on their website.

It said, these examples remind us that there’s much more to do to address the climate crisis and biodiversity loss, but also offer the promise of hope and optimism.

The islands of Turks and Caicos are represented by the letter “G.” The islands’ conservation efforts are concentrated on protecting important regions for biodiversity and addressing persistent environmental problems.

The largest reef in the southern Gulf of Mexico and a UNESCO biosphere reserve, Scorpion Reef National Park, is represented by the letter “O” in the Mexican flag.

The letter “O” features Iceland’s Vatnajokull National Park, which was designated as a national park in 2008 following decades of advocacy. The ecology within and surrounding the biggest glacier in Europe is safeguarded by this UNESCO World Heritage Site.

The letter “G” has the Jau National Park in Brazil on it. It is a UNESCO World Heritage Site and one of the biggest forest reserves in South America.

The Great Green Wall of Nigeria is represented by the letter “L,”  and the Pilbara Islands Nature Reserves of Australia are represented by the letter “E.”

Meanwhile, Earth Day is a worldwide event that promotes protection of the environment every year. April 22 serves as a reminder of the importance of conservation efforts and sustainable practices to guarantee a healthier world and a brighter future.

The occasion inspires people across the world to come together and take action to protect the environment, strengthening our bonds with nature and promoting good change.

After taking part in the first season of the singing reality show Indian Idol, Rahul Vaidya gained widespread recognition. In addition to Bigg Boss, he took part in Khatron Ke Khiladi 11.

Meanwhile, heavy rains that triggered flooding in the UAE and Bahrain, which left 18 people dead in Oman on Sunday and Monday, have paralyzed the financial hub of the Middle East, Dubai.

A lot of incoming flights were diverted from Dubai’s international airport because of the rain. At 7:26 p.m., the busiest airport in the world for foreign visitors stopped accepting new arrivals; a gradual resumption was announced for more than two hours later.

Images of planes navigating flooded tarmacs are making the rounds on social media.

According to pictures shared on social media, the flagship malls Dubai Mall and Mall of the Emirates both experienced heavy floods, while at least one Dubai Metro station had water up to the ankles.

There were several road collapses, severe flooding in residential areas, and numerous reports of leaks from windows, doors, and roofs.

1 person was killed in UAE as it witnessed heavy rainfall on Tuesday, stranding commuters, flooding roads, disrupting trains and flights and resulting in water leakage from mall ceilings. The UAE witnessed record-breaking rainfall on Tuesday and the National Centre of Meteorology recorded 254 mm of rainfall in less than 24 hrs in the Khatm Al Shakla area in Al Ain. It is being said that the rainfall was the highest documented since the start of data collection in 1949.

The heavy rainfall in UAE came days after a similar situation in neighbouring Oman, where 13 people were killed in flash floods. Many parts of Oman saw torrential rains, which caused students to be trapped in buses and swept away motorists and trapped people in their homes.

Videos from Dubai circulating on social media showed widespread waterlogging on roads in Abu Dhabi, Dubai and other important cities. This left daily commuters in cars and other vehicles struggling to get back home. Dubai metro station too was seen flooded and closed.

One such video circulating on social media shows the aerial view of the city of Dubai from the top of a building. In the video the stormy winds are seen blowing over the city of Dubai. As the storm intensifies the Dubai sky turns green and ultimately gets covered by heavy rainfall. The video has gone viral on social media with more than 1.1 million views.

Another video showed water leakage from the ceilings of shopping malls, flooding the floors and destroying goods. A video which was shot in the famous Mall of the Emirates, showed pieces of ceiling falling as the rainwater gushed inside. Videos from many outlets of the Deira City Centre mall chain showed escalators being rendered unusable. Majid Al Futtaim, the company which owns the Mall of Emirates, said that the shopping complexes have been kept open and the customers are being sent away from the flooded areas.
