When Alice falls into the rabbit hole
, she experiences a host of "curiouser and curiouser" phenomena. She gets smaller, she gets bigger, she almost drowns in a sea of her own tears and she meets an assembly of strange creatures. As it turns out, falling into a black hole may rival the strange experiences described by Lewis Carroll in his classic fantasy. Unlike Alice, however, who emerges from her adventures no worse for the wear, a person who journeys into one of the universe's most mysterious objects is not likely to fare so well. To understand why, it will help to define what a black hole is and how it interacts with the universe around it.
Astronomers have only observed black holes indirectly, yet they can paint a clear picture, albeit one based on circumstantial evidence. They feel certain, for example, that black holes indicate regions where matter has been compressed into an infinite density. The gravity of such a region is so strong that nothing can escape its inexorable pull, not even light. As matter and light fall into the superdense region, X-rays and other forms of electromagnetic energy get blasted into space. It's this cosmic ejecta that alerts astronomers to the existence of these mysterious monsters.
Like monsters we can see, black holes come in different sizes.
Astronomers measure this using something known as the Schwarzschild radius. That radius describes the size of the event horizon, the spherical boundary of a black hole. The greater the object's mass, the larger its event horizon and the larger its radius. Regardless of how massive it is, a black hole's center point is what astronomers call a singularity -- a place where matter is infinitely dense.
Of course, you'll have to find one of these objects if you're going to fall into it. We'll search for one next.
It may seem as if these pictures were taken from another planet,but they are actually shots of the Mendenhall Glacier which stretches 12 miles. It is located in Mendenhall Valley, approximatelyanother 12 miles from downtown Juneau in the southeast are the U.S.state of Alaska. The mammoth glacier and its immediate landscape area is protected as the 5,815-acre Mendenhall Glacier Recreation Area, a federally-designated unit of the Tongass National Forest.
The 19 kilometer long Mendenhall Glacier is an extraordinary
delight for both adventurous seekers as well as photographers such as Kent Mearig who goes beneath the glacier to capture its one-of-a-kind ice caves.
Salar de Uyuni or Salar de Tunupa is a true blue paradise. This salt island 12,500 km ² is located in the highlands of southwestern Bolivia at over 3658 meters altitude. Who is now more than 10 000 years, it offers spectacular scenery and is one of the most beautiful places on the planet.
The Salar de Uyuni was created when a prehistoric lake dried up and left a salty crust behind. When it rains, the salty crust becomes a giant mirror.
The train goes three times a day and delivers wood to the factory. However, the trees make a green corridor, which attracts many couples, as well as photographers for its eye catching avenue.
It is said that if you and your beloved come to the Tunnel of Love and sincerely make a wish, it will come true. This might be a new romantic place to discover.
This phenomenon has not been well - documented in the past. Some peple say that the temple of Wat Luang has a centuries-old records have spotted these fireballs. There are also reports and notifications of British soldiers registered since the sixties of the last century during the colonial period, although there is no strong evidence of an assertive and to see those balls .
And is celebrated the emergence of those fireballs on specific days of the month of October , but sometimes end up disappointed by the celebration does not appear that balls that Atgmehr the other to see it. In 2001 vision has been reported fireball 3000 , while 2004 was disappointing , but 2008 was a fantastic year by a description of the visitor there .
Scientific explanation :
It's not just people see ghosts on occasions, it will be seen by thousands of people were photographed Photography as well as Falemya . She says some scientific reports that this phenomenon is caused by the movement of rising gas bubbles from the waters of the Mekong , and when it bubbles up to the surface begins combustion gas and stems to the top.
Some scientists say that these gases rise to the top at the completion of the full moon , which affects the ascent while researchers built some very complex theories about the form of gases in the river sediments with the movement of the moon and the UV rays of the sun .
There is even today a clear scientific explanation for this strange phenomenon in the Mekong River .
The flower with the world's largest bloom is the Rafflesia arnoldii. This rare flower is found in the rainforests of Indonesia. It can grow to be 3 feet across and weigh up to 15 pounds! It is a parasitic plant, with no visible leaves, roots, or stem. It attaches itself to a host plant to obtain water and nutrients. When in bloom, the Rafflesia emits a repulsive odor, similar to that of rotting meat. This odor attracts insects that pollinate the plant.The reason for the bad smell created by the ‘Rafflesia arnoldii’ is usually to appeal to its main pollinator. The name of pollinator is carrion fly. The specialist Rick Gregory from the site ‘Nature Escapes’ insights these flies get to colonies to look into every single Rafflesia arnoldii searching for decomposing steak, just to be dissatisfied in order to find independently coated in tacky glob of plant pollen through the big opening from the Rafflesia arnoldii flower. This blossom’s surviving depends upon “Carrion fly” going to initially a male and after that feminine blossom to be sure pollination as well as imitation within the plant’s forest atmosphere.
Another enormous flower found in Indonesia is the Amorphophallus titanum, or Titan arum. It is also known as the "corpse flower" for its unpleasant odor. Like the Rafflesia, the Titan emits the smell of rotting flesh to attract pollinators. Technically, the Titan arum is not a single flower. It is a cluster of many tiny flowers, called an inflorescence. The Titan arum has the largest unbranched inflorescence of all flowering plants. The plant can reach heights of 7 to 12 feet and weigh as much as 170 pounds!
