Gamma ray bursts, powerful flashes of light, are the brightest events in our universe that last no longer than a few seconds or minutes.
Some people in general believe that these are messages of alien civilizations. And scientists managed to recreate a mini-version of the gamma-ray burst in the laboratory, opening a completely new way of investigating their properties. The results were published in Physical Review Letters.
One of the reasons for the occurrence of gamma-ray bursts is that they are somehow born in the process of ejecting jets of particles created by massive astrophysical objects, such as black holes. <\em>
This makes gamma-ray bursts extremely interesting for astrophysicists. Their detailed research can reveal the key properties of black holes in which these outbreaks are born.
The most powerful laser in the world
Recently, it has been suggested that the best way to find out how gamma bursts are generated is to imitate them on a small scale in the laboratory, creating a small source of electron-positron beams, and to see how they develop, left to their own devices.
Scientists from the United States, France, Britain and Sweden have managed to create a small version of this phenomenon, using the most powerful on Earth lasers like the Gemini laser, owned by the Rutherford-Appleton Laboratory in England.
How powerful is the strongest laser on Earth? Take all the solar energy that covers the entire Earth, and squeeze it to a few microns.
To much informative post @prosto. Acquired much knowledge on the gama-ray and it's misconception as aliens.
