Albert Einstein’s Century-old Prediction comes True: Third Gravitational Waves detected by Scientists
- For the third time, scientists have detected the gravitational waves validating Albert Einstein’s predictions
- The prediction was made a century ago
- The latest detection has strong implications on the nature of black holes and dark matter
June 04, 2017: The third set of gravitational waves has recently been detected by LIGO (Laser Interferometer Gravitational-Wave Observatory), a complex yet effective experiment to detect gravitational waves. The detection validates Albert Einstein’s theory that space compresses and stretches itself.
The prediction was made a century ago. The successful detection also holds significance for the true nature of black holes and dark matter. It puts the predicted theory to test!

The historic moment was witnessed by the international research team, including scientists from India. The faint hum of the waves can only be heard by the cutting edge science and sensitive detection of LIGO. The wave is produced when two black holes merge together.
The latest detection is called GW170104 for which the observations began last year. Gravitational waves were first observed in September 2015 and then in December of the same year.
The third waves have been detected twice as far from the Earth as the earlier two detections. The combined black hole has a mass about 49 times more than that of the sun. The merger of the two black holes can be traced back 3 billion years ago.
The waves are studied in a research paper that has received acceptance for publication by journal ‘Physical Review Letters’. IIT Madras has contributed significantly to the study. It models the gravitational waves sources and tests the consistency of signals.
NewsGram brings to you current foreign news from all over the world.
Scientists say that the new detection advances their goal of observing ancient events through waves, otherwise invisible through other means.
LIGO is based in the US. But India is working to set up its own observatory as well. India hopes to set it up by 2024. India looks to contribute to the global scientific knowledge.

International Civil Aviation Day is observed on December 7th to recognize the flying industry’s impact on modern society. In 1994, as part of ICAO’s (International Civil Aviation Organization) 50th-anniversary celebrations, the first International Civil Aviation Day was observed, and in 1996, the United Nations General Assembly declared December 7th as International Civil Aviation Day.
Aviation has revolutionized tourism and business forever, not to mention the cultural linkages that have been made possible. The purpose of this day is to emphasize the significance of civil aviation in social and economic development, as well as to highlight the unique role played by the International Civil Aviation Organization in assisting nations in cooperating and bringing a truly global transit network to reality. With the adoption of Agenda 2030 by the United Nations, a vow to reduce pollution with the eventual aim of a new era in global sustainable development, the role of aviation remains just as essential.

The theme of International Civil Aviation Day is changed every five years. For the whole four-year gap, one theme is continued. From 2020 until 2023, “Advancing Innovation For Global Aviation Development” is the theme. This theme will place a greater emphasis on innovation in all aspects of air transportation, with the organization supporting ideas through a more proactive and dynamic assistance strategy.
HOW IS IT CELEBRATED?
The International Civil Aviation Organization conducts a variety of activities and events throughout the day, including seminars, training sessions, and news announcements on international civil aviation topics. Governments, organizations, businesses, and even individuals support the ICAO.

Business owners hardly have time to look into all aspects of a business operation, and accounting is one aspect. While small business owners might invest some time handling accounting services, it is indeed a big waste for owners of major enterprises. Regardless of the size of the business, your organization needs someone to look after the ledger.
Hiring an Accountant for your Firm - Things to Consider
When seeking out an accounting service, you have to opt for a professional with the level of experience you need. Here are things to consider when choosing an accountant.
- Neat and organized
Incomplete data entries and loopholes in the ledger are significant factors in slowing down the accounting process. If your accountant is not focusing on the job, chances are he will overlook important details. Such a discrepancy in the ledger book can mislead everything to a messy dead end. You never know that today’s entry would play a significant role in saving your company when people from taxation show up at your doorway. That is why only reputed accounting services can have an excellent eye for detail. Such a company focuses on the financial and success of your business.
- Handy in computer software
As per Aron Govil, the reliability of accounting has nothing to do with a high profile in computer science, but modern businesses hugely rely on technology to keep up with the latest trends. For example, if your competitor uses technology to manage the financial subject, you cannot stick to the traditional paper register. When the accountant on a computer gets efficient and accurate results quickly, the one with paper may lag due to continuous error. Even if he is not making any errors, the automatic calculation will consistently be faster than manual counting. You must look for such accounting services that can easily integrate various software on your accounting operations and utilize them seamlessly.
- Temporary or permanent accountant
An organization with a couple of accountants cannot take care of every financial detail. They might work with their trustworthy accountant for a long time, but a new business strategy could force them to reshuffle their positions. In this situation, they might need more accounts instead of an accountant. Looking into the type of business trait, you should decide on a service that suits your requirements. Well, it depends upon the business you are running and your budget; you need to figure out whether you need to hire a part-time accounting service or a full-time accounting agency. Along with the budget, your accounting operations also contribute to making these decisions; if you have a good amount of substantial accounting actions to take care of, then you must have a permanent accounting service.
Most businesses usually have accountants, but not all invest in accounting because they work with experts. As per Aron Govil, find an accounting service provider if you still cannot afford that facility. Hiring the right accounting agency is the most crucial aspect, as you will be putting financial responsibilities over the shoulder of professionals. So, try to find the best and most trustworthy accounting experts for your business. You can consider looking for them online by going through the reviews and their websites.

Since the 7th of December 1949, the Armed Forces Flag Day has been observed in India, annually. This one day is dedicated towards collection of funds from the citizens of India for the welfare of the ‘Indian Armed Forces personnel’. It has become a tradition to pay respect to the people who have served in the army, Navy and Airforce, on this day.
“The idea behind observing a Flag Day was to distribute small flags to the general population and in return collect donations.” The color-scheme of the flag is very similar to the ones used by fellow Commonwealth members like Cyprus, Kenya and Nigeria. The Flag Day signifies that it is the responsibility of the citizens of India to take care of the families and dependents of the armed forces personnel who fight for the country.

A need for such a day was realized by the Government after India gained Independence from the British rule. In order to manage the welfare of its defence personnel, the Defence Minister of India and a committee together decided to recognize 7th December as the Flag Day. This decision was taken on the 28th of August 1949.
The then Prime Minister Jawaharlal Nehru inaugurated the day saying that,
“A few weeks ago, I visited Indo-China and saw our officers and men attached to the International Commission there. It gave me a thrill to see their smart bearing and the good work they were doing in that distant land. What pleased me still more was their general popularity with the people there. By their efficiency as well as their friendliness, they enhanced the reputation of India. Among them were people from all parts of India. They observed no provincial or other differences amongst themselves. I am sure my countrymen will be pleased to learn of them and would like to indicate their appreciation of these young men who serve our country both here and elsewhere so well. A way to indicate that appreciation is to contribute to the Flag Day Fund.”

The fund is collected through official and non-official means with the help of voluntary organizations. The Kendriya Sainik Board, which is under the Ministry of Defence, arranges for the collection of the fund.
The Defence Ministry of India decided to integrate all the related welfare funds into a single unit called the Armed Forces Flag Day fund. The funds that were integrated are:
- Amalgamated Special Fund for War Bereaved, War Disabled and other ex-Servicemen/Serving Personnel
- Flag Day Fund
- St Dunstan's (India) and Kendriya Sainik Board Fund
- Indian Gorkha Ex-Servicemen's Welfare Fund
The Flag Day signifies that it is the responsibility of the citizens of India to take care of the families and dependents of the armed forces personnel who fight for the country.Unsplash
Problems have to be resolved by and welfare of the ex-servicemen and dependents are mostly settled by the States and the Union Territories, although it was to be a shared responsibility between the Union Government, the State Governments and the governments of the Union Territories. In order to help the Central Government in carrying out this process, there are 32 Rajya Sainik Boards and 392 Zila Sainik Boards. The Kendriya Sainik Board, the Rajya Sainik Board and the Zila Sainik Board are all responsible for the policy formulation and implementation of resettlement and welfare schemes for ex-servicemen, widows and their dependents residing in their respective States or Union Territories or Districts.(Keywords : armed, forces, flag, india, independance, donation, citizen, army, navy, airforce, tradition, respect, government, state, center, union territory, district, funds.)
