supermassive black hole

Supermassive black hole

From Wikipedia, the free encyclopedia
A Black Hole’s Dinner is Fast Approaching - Part 2.ogv
A gas cloud with several times the mass of the Earth is accelerating towards a supermassive black hole at the centre of the Milky Way.

A supermassive black hole is the largest type of black hole in a galaxy, on the order of hundreds of thousands to billions of solar masses. Most, and possibly all galaxies, including the Milky Way[2] (see Sagittarius A*), are believed to contain supermassive black holes at their centers.[3][4]

Supermassive black holes have properties which distinguish them from lower-mass classifications. First, the average density of a supermassive black hole (defined as the mass of the black hole divided by the volume within its Schwarzschild radius) can be equal to, for stellar-mass black holes, or less than the density of water in the case of some supermassive black holes.[5] This is because the Schwarzschild radius is directly proportional to mass, while density is inversely proportional to the volume. Since the volume of a spherical object (such as the event horizon of a non-rotating black hole) is directly proportional to the cube of the radius, the density of a black hole is inversely proportional to the square of the mass, and thus higher mass black holes have lower average density. Also, the tidal forces in the vicinity of the event horizon are significantly weaker. Since the central singularity is so far away from the horizon, a hypothetical astronaut traveling towards the black hole center would not experience significant tidal force until very deep into the black hole.

Spring cleaning and visiting one another

Spring cleaning, or Khouneh Tekouni (literally means 'shaking the house') or 'complete cleaning of the house' is commonly performed before Nowruz. Persians and other Indo-Iranian groups (Kurds, Azarbaijanis and Balochs) start preparing for the Nowruz with a major spring-cleaning of their houses, the purchase of new clothes to wear for the new year and the purchase of flowers (in particular the hyacinth and the tulip are popular and conspicuous).

In association with the "rebirth of nature", extensive spring-cleaning is a national tradition observed by almost every household in Iran. This is also extended to personal attire, and it is customary to buy at least one set of new clothes. On the New Year's Day, families dress in their new clothes and start the twelve-day celebrations by visiting the elders of their family, then the rest of their family and finally their friends. On the thirteenth day families leave their homes and picnic outdoors.

During the Nowruz holidays, people are expected to visit one another (mostly limited to families, friends and neighbors) in the form of short house visits, which are usually reciprocated. Typically, on the first day of Nowruz, family members gather around the table, with the Haft Seen on the table or set next to it, and await the exact moment of the arrival of the spring. At that time gifts are exchanged. Later in the day, the first house visits are paid to the most senior family members. Typically, the youth will visit the elders first, and the elders return their visit later. When in previous year, a family member is deceased, the tradition is to visit that family first (among the elders). The visits naturally have to be relatively short, otherwise one will not be able to visit everybody on their list. A typical visit is around 30 minutes, where you often run into other visiting relatives and friends who happen to be paying a visit to the same house at that time. Because of the house visits, you make sure you have a sufficient supply of pastry, cookies, fresh and dried fruits and special nuts on hand, as you typically serve your visitors with these items with tea or sherbet. Many Iranians will throw large Nowruz parties in a central location as a way of dealing with the long distances between groups of friends and family.

Some Nowruz celebrants believe that whatever a person does on Nowruz will affect the rest of the year. So, if a person is warm and kind to their relatives, friends and neighbors on Nowruz, then the new year will be a good one. On the other hand, if there are fights and disagreements, the year will be a bad one. As an extended tradition to the holiday, men may or may not choose to shave their faces until the night of the "New Day" as a sign of removal of old habits and tendencies and the rebirth of their faith and being.

One tradition that may not be very widespread (that is, it may belong to only a few families) is to place something sweet, such as honey or candy, in a safe place outside overnight. On the first morning of the new year, the first person up brings the sweet stuff into the house as another means of attaining a good new year.

The Mysterious Doorway of Aramu Muru دروازه ستارگان

The Mysterious Doorway of Aramu Muru


Located in the remote mountain region of southern Peru is a mysterious place revered by local Peruvians as 'The Place of the Gods'. Known as the Doorway of Aramu Muru, it stands near the border with Bolivia on Lake Titicaca where Inca legend says life was first created on Earth.

The doorway, a squarish stone cut-out in a flat, cliff outcropping, is surrounded by mystery. Hidden in a land full of Inca ceremonial chulpas and other rock-carved temples, the doorway is purported to be a passageway to another dimension. Locals have claimed that people have dissappeared and reappeared near the door. Many refuse to get close to the door claiming it to be a portal for the ancient gods. Some have noted strange, tall men accompanied by glowing balls of lights and walking through the doorway.

Do Heaven and Hell Exist Now?

heaven and hell

Imam Reza was asked by a follower: “Do Heaven and Hell exist now?”‌

Imam Reza said, “They do, and Prophet Muhammad has seen them in his Ascent.”‌

“Some believe that the Heaven and the Hell have not been created yet,”‌ asked him.

“They are not among us and we are not among them,”‌ said Imam Reza, “Anyone who denies the existence of Heaven and Hell, do not pay attention to the truthfulness of what Prophet Muhammad and we say.”‌

God states in the Qur’an, “They are burning in the fire of the Hell, which they were denying.”‌

Prophet Muhammad also said, “When I was taken to the heavens in the Ascension night, Gabriel took my hand and led me to the Heaven. He gave me a date from Heaven and when I ate it, the light of Fatimah, peace be upon her, was born inside me. Then I went back to the earth, went to Khadijeh and she became pregnant with Fatimah. Fatimah is a heavenly human. Whenever I miss the Heaven, I smell her.”

زبان انگلیسی (۱)

English is a West Germanic language that arose in the Anglo-Saxon kingdoms of England and spread into what was to become south-east Scotland under the influence of the Anglian medieval kingdom of Northumbria. Following the extensive influence of Great Britain and the United Kingdom from the 18th century, via the British Empire, and of the United States since the mid-20th century,it has been widely dispersed around the world, becoming the leading language of international discourse and the lingua franca in many regions. It is widely learned as a second language and used as an official language of the European Union and many Commonwealth countries, as well as in many world organisations. It is the third most natively spoken language in the world, after Mandarin Chinese and Spanish.It is the most widely spoken language across the world.

Historically, English originated from the fusion of languages and dialects, now collectively termed Old English, which were brought to the eastern coast of Great Britain by Germanic (Anglo-Saxon) settlers by the 5th century – with the word English being derived from the name of the Angles, and ultimately from their ancestral region of Angeln (in what is now Schleswig-Holstein).A significant number of English words ......

Melancholy association


Melancholy association


Autumn in poetry has often been associated with melancholy. The possibilities of summer are gone, and the chill of winter is on the horizon. Skies turn grey, and many people turn inward, both physically and mentally.[11]

Similar examples may be found in Irish poet William Butler Yeats' poem The Wild Swans at Coole where the maturing season that the poet observes symbolically represents his own ageing self. Like the natural world that he observes he too has reached his prime and now must look forward to the inevitability of old age and death. French poet Paul Verlaine's "Chanson d'automne" ("Autumn Song") is likewise characterised by strong, painful feelings of sorrow. Keats' To Autumn, written in September 1819, echoes this sense of melancholic reflection, but also emphasises the lush abundance of the season.

Take Control of Your Life or

Each day you have the ability to make the choice to take control of your life, or to let it control you. You can either be proactive, or you can let circumstances call the shots.  To take control of your life or exercise personal leadership is to take responsibility for yourself and for every area of your life. It means being connected with your values, your vision and to set meaningful goals for yourself. When you do, you become more productive, more optimistic, able to solve problems more easily and ultimately have less stress in your life.

No doubt, with all the chaos and uncertainty that is going in the world these days it may be difficult to feel like you are in charge of your life, and while there are some things you have no control over, there is much that you do. Understand that you are the principal architect and creator of your life and that you are where you are at, because of the choices and decisions you have made thus far. 

An interesting concept that I came across in my readings recently, and as it relates to personal leadership, is to see yourself as the CEO of your own life. If you were to apply it to yourself, how would run your life? What kind of strategic planning would you do and how would you envision your future? I would guess that in seeing yourself as the CEO of your life, you would be inspired to think in a more effective, results oriented manner.

As your own CEO, here are some ways in which you can take control of your life and exercise personal leadership:

Determine your values and what's important to you.  As I wrote in Have A Personal Value System, knowing what your values are gives you structure and purpose, which in turn directs you on how to focus your time and efforts. It would be similar to the 'mission statement' a company would hold. As you probably know, a mission statement typically spells out the overall goals and drives the actions of an organization. It likewise provides a roadmap and guides the decision-making processes for management.  In your life your mission statement could be something like: "My purpose is to live life to the fullest by taking the care of my health, relationships, finances and overall happiness to the best of my abilities."
