Gamma ray bursts are highly energetic explosions which have been observed at remote cosmic distances from us.
They are by far the most powerful and brightest electromagnetic events known to happen in the Universe. Bursts can last up to ten seconds to ten minutes. When this happens, huge amounts of high-energy radiation (at least a million times the energy output of the sun) burst from a space origin, travelling at the speed of light.
Gamma-rays are emitted when high-energy particles collide with electrons in a neutral mass.
This is common in white holes, extremely compact extremely dense stellar matter, and very old and very big stars. The white hole is made of gas that contains relatively few electrons. This is why it is called “white.” The other kinds of neutral matter that gamma rays can come out of include pulsars, quarks, voids, and some low-mass stars.
Gamma rays are emitted from very close explosions in compact molecular systems.
These can happen anytime within the galaxy or the universe, although they are most commonly seen in gamma-ray bursts which happen in very close orbiting galaxies. Many astronomers believe that these explosions are produced from black holes which are extremely dense centers of cold plasma that lie very close to the surface of the innermost stars. This is the reason why we hear the loud whistling sounds from such explosions.
Short events may be gamma bursts as well as white holes.
For instance, a gamma ray burst seen by astronomers was classified as a gamma ray burst. It was observed by NASA’s Swift telescope. There were about two to three times as many protons in this gamma burst as there were neutrons. The protons were in a state of high energy, which is required for them to create a gamma pulse.
Long gamma pulse with very high energy can only be produced when this nucleus has a very low density, which is about one atom per million, similar to the lowest density that makes a black hole. This kind of emission takes place in a merger between a white hole or a supergiant planet and an interlinking gas cloud. The gas cloud, however, can not be an evaporating gas like the gas that makes up the Earth, since it would not have sufficient strength to pull away from a star at such a great distance. Thus, it is believed that the bursts were caused by collisions or near misses with another asteroid or comet.
There have been detected a number of terrestrial gamma rays over the past years.
A number of them had a very long wavelength, which could only be obtained from very near by using telescopes or spy satellites. However, more recent bursts were found through more energetic gamma rays that were emitted from more distant objects. Most of these bursts occurred near the comet’s Endeavour and Hale-Bopp, and many of them were discovered using a variety of data sources.
There are several theories on why these gamma ray bursts occur.
The scientists believe that a collision between a white dwarf asteroid and a companion comet or a relative giant planet caused them.
One proposed idea is that the merger occurred close to the inner solar system and that the gas cloud was not capable of escaping to form a stable region, whereas a second theory is that a large asteroid hit the companion star causing it to spew out a huge amount of dust into space. Some even believe that a giant space dust cloud may have existed in the inner solar system for more than three billion years. No direct evidence of these theories have ever been found, and astronomers are trying hard to find a companion to study in detail.
Scientists have detected several other explosions but none of them were caught using existing technology.
With the recent discoveries of the Vela satellites, we are now able to observe these phenomena much more readily than we used to. These satellites operate by bouncing microwave radiation off known celestial objects to study their composition and to determine their potential energy output.
This kind of research is important because it can help us better detect these cosmic explosions and thus better understand them. These models are also helping us refine models that will allow us to observe these phenomena in greater detail in the future with more effective tools, such as gravitational lensing satellites or Very Large Telescope (VLT) instruments.
