Scarlett Johansson as the Black WidowAvengers official FacebookAvengers: Endgame movie released earlier this week and it instantly broke all the box-office predictions. The movie made a whopping $60 million on opening day and movie experts are predicting that it will garner more than $1 billion. Apart from the box-office success, the movie will be remembered for several iconic sequences and particularly the one which happened between Black Widow and Hawkeye.Major spoilers for Avengers Endgame movie:As we have covered in our previous Avengers Endgame time travel post, Black Widow and Hawkeye goes to Vormir to get the Soul Stone. As we learned in Avengers: Infinity War, the only way one can acquire Soul Stone is by sacrificing the one person he or she loves the most. In IW, Thanos sacrificed his daughter Gamora.Black Widow and Hawkeye had a discussion as who is going to die and who is going to get the stone. After a lot of heated argument that involved punching and hurting each other physically, we see how Black Widow dies and Hawkeye comes back to the present storyline with the Soul Stone.If Black Widow is dead then what it means for Scarlett Johansson’s solo Black Widow movie?Scarlett Johansson has played Natasha Romanoff from Iron Man 2 and has remained a core member of the Avengers team. Before Captain Marvel, she was the only woman in the group and her presence meant a great deal especially to Bruce Banner aka Hulk. Scarlett Johansson at the press event for Avengers: EndgameTwitterAs earlier reported, a solo Black Widow movie was in development by Marvel with a May 2020 release. Cate Shortland is attached to direct the project and stars like Rachel Weisz, Florence Pugh, and David Harbour are going to play some important roles. At first, we were speculating that the solo Black Widow movie will feature Natasha’s story after the events of Avengers Endgame movie but the character’s death has proved that the upcoming solo movie will be a prequel story, which means that we might get to see other Avengers as well.As of now, neither The Walt Disney Company and Marvel Studios have confirmed the plot details of Black Widow movie but since the lead character is dead, it is most likely that they will be working on a prequel movie. We are not sure whether we get to see Tony Stark in the upcoming Black Widow movie but characters like Clint Barton aka Hawkeye, Captain Marvel, and Nick Fury may come in some capacity.Production of solo Black Widow movie is expected to begin after the release of Spider-Man: Far From Home.
, Astrophysical Journal , arXiv A trio of researchers with The University of Hong Kong, Academia Sinica Institute of Astronomy and Astrophysics in Taiwan and Northwestern University in the U.S., has come up with an alternative theory to explain how some stellar-mass black holes can grow bigger than others. In their paper published in The Astrophysical Journal Letters, Shu-Xu Yi, K.S. Cheng and Ronald Taam describe their theory and how it might work. Citation: Another way for stellar-mass black holes to grow larger (2018, August 17) retrieved 18 August 2019 from https://phys.org/news/2018-08-stellar-mass-black-holes-larger.html Since the initial detection of gravitational waves three years ago, five more detections have been observed—and five of the total have been traced back to emissions created by two stellar-mass black holes merging. The sixth was attributed to neutron stars merging. As part of their studies of such detections, space researchers have been surprised by the size of the stellar-mass black holes producing the gravity waves—they were bigger than other stellar-mass black holes. Their larger size has thus far been explained by the theory that they grew larger because they began their lives as stars that contained very small amounts of metal—stars with traces of metals would retain most of their mass because they produce weaker solar winds. In this new effort, the researchers suggest another possible way for stellar-mass black holes to grow larger than normal.The new theory starts out by noting that some supermassive black holes at the hearts of galaxies are surrounded by a disk of gas and dust. In such galaxies, there are often stars lying just outside the disk—stars that could evolve to become stellar-mass black holes. The researchers suggest that it is possible that sometimes, pairs of these stars wind up in the disk as they evolve into black holes. Such stellar-mass black holes would pull in material from the disk, causing them to grow larger. The researchers note that if such a scenario were to play out, it is also possible that the two merging stars could wind up with a synchronized spin resulting in a stellar-mass black hole that produces more gravity waves than if the spins had not been synchronized, making them easier for researchers to spot.

DOI: 10.3847/2041-8213/aac649 , On Arxiv: https://arxiv.org/abs/1805.07026AbstractAmong the four black hole (BH) binary merger events detected by the Laser Interferometer Gravitational-Wave Observatory (LIGO), six progenitor BHs have masses greater than 20 M ⊙. The existence of such massive BHs suggests that extreme metal-poor stars are the progenitors. An alternative possibility, that a pair of stellar mass BHs each with mass ~7 M ⊙ increases to >20 M ⊙ via accretion from a disk surrounding a supermassive BH (SMBH) in an active galactic nucleus (AGN), is considered. The growth of mass of the binary and the transfer of orbital angular momentum to the disk accelerates the merger. Based on the recent numerical work of Tang et al., it is found that, in the disk of a low-mass AGN with mass ~106 M ⊙ and Eddington ratio >0.01, the mass of an individual BH in the binary can grow to >20 M ⊙ before coalescence, provided that accretion takes place at a rate more than 10 times the Eddington value. This mechanism predicts a new class of gravitational wave (GW) sources involving the merger of two extreme Kerr black holes associated with AGNs and a possible electromagnetic wave counterpart.

The strong gravity of the black hole, on the left, is pulling gas away from a companion star on the right. This gas forms a disk of hot gas around the black hole, and the wind is driven off this disk. Credit: NASA/CXC/M.Weiss This document is subject to copyright.

Airbnb—the room rental company that does not own any rooms—has just sued the city of New York. Why? This is because the city has introduced a bill to penalise anyone who rents out their apartment for less than 30 days. This would effectively kill Airbnb’s business, which makes every household owner a potential hotelier. Airbnb provides an online listing system—anyone who owns a house, or many properties can rent out space. The business cuts into the profits of conventional hotels who have to buy land, build rooms and take care of the establishment. In Airbnb’s case, the costs are low and distributed. More importantly, thousands, even millions, of rooms suddenly become available, which eat into the market of house rentals or hotels. Airbnb is, not surprisingly, hitting old business, which also is hitting back. Also Read – Add new books to your shelfIt is also difficult to regulate. Just think. How do city governments control millions of property owners who have become instant hoteliers? Airbnb argues that its reputational system, where owners and guests rate each other, regulates the informal market. Governments disagree. Airbnb is fighting similar battles in Amsterdam, Barcelona, Berlin and even in its hometown of San Francisco, and the list is growing. Uber—the taxi service that does not own any cars—has similar battles on hand. Uber, and others like it, have turned every car owner into a potential service provider. All that Uber does is to aggregate these millions of car owners who have overnight become taxi drivers. This is why it can reduce costs and work the market—drastically undercut the market price and drive regular taxi service into the red. All this without owning a single car.

I saw this at close hand when the Supreme Court of India directed that all taxis, including those run by aggregators like Uber or Ola, should convert to CNG. This was done to reduce Delhi’s runaway air pollution. But the result of this seemingly simple order was out and out war. All taxi owners—from the black and yellow, radio taxi, to the tourist taxi and all India tourist taxi—converged at the Environment Pollution (Prevention and Control) Authority (I am a member of it), which is required to oversee the implementation of the Supreme Court’s direction. They had only one demand: stop Uber and Ola. Our objective was different—to regulate the fuel used by taxis and not to stop their operations. But regulation is a challenge. In the very first meeting, the police informed us that they are helpless. They could not identify the taxi—every car had become a taxi. Uber and Ola told us that they were not taxi operators—only aggregators. In fact, their companies are registered as information technology providers. They were also not responsible for anything—customers hired cars using their platform and rated the service provided by drivers. The Delhi government had issued guidelines, which would curtail the operations of such aggregators, but Uber challenged this in the court. Finally, after weeks of protracted discussions, and often violent disagreements, it was agreed that all taxis, including those listed with the aggregators, would run on CNG. But all other issues, including the contentious issue of surge pricing, remained unresolved. Governments in India and abroad are battling with taxi operators and technology companies to formulate these rules. But why am I writing this now? The fact is Airbnb and Uber are part of the inevitable change in our future. The reason is that the modern world has formalised its economy to the point that it has become unviable. The brick-and-mortar world requires massive infrastructure, and this then requires regulations to ensure that all this operates within rules. The cost of regulations is also high and adds to the cost of running the economy. In my view, Uber and Airbnb are undercutting this world—by making the best use of the individual’s assets. In both cases, they are optimising existing resources—the cars and houses people own—to make more money and share the profits. But most importantly, these businesses are working the informal space. They are doing this to reduce costs and to expand opportunity. This is where we need to think further of what our world is about. In countries like India, informal business is the existing order of the day. Everything—from collecting sewage from homes, recycling garbage to providing transport in our cities—is managed by millions of myriad informal businesses. But we do not consider it part of our future. Worse, it defies regulation as we know it today. So, it must go. But given that the formal economy comes with costs, we cannot replace this informal and thriving business. But to kill it we neglect it; make it illegal, and altogether despise it. But still, it stays. We just can’t make it work. So, is it time we thought of a different business future? Let’s discuss this again.(The writer is Editor of Down To Earth magazine.
