Planet Earth is exposed to many dangers, first of all global warming, which is undoubtedly one of the most current problems of this period, with glaciers melting and temperatures rising dramatically, destroying a large part of the ecosystem. However, it is not only global warming that threatens the planet: another danger is gamma rays. Let’s find out what exactly they are, and what could happen in the hypothetical future.
As defined by astronomers and scientists in general, gamma-ray bursts consist of gamma-ray bursts, which can vary greatly in duration. For this, they are classified and distinguished at the scientific level respectively in Short-lived gamma-ray bursts (lasts a few seconds) e Long-lasting gamma-ray burstsif they last more than a few seconds, sometimes touching hours, as in the case of very long gamma-ray bursts, although in this case the scientific community did not agree to classify them.
These gamma rays have a very high power, It enables isotropic energy to be emitted resulting in explosions which, in some cases, They can even reach 1048 jouleswhich is nearly infinite energy when compared to the energy of the Sun, making it the most powerful transient phenomenon ever observed within the Solar System as well as in the entire universe.
During the past few months in particular, an explosion in the form of gamma radiation has been identified, at a distance of about 13.4 billion light years, until I managed to reach the planet Earth. It is clear at the moment that the distances and their measurement results are indicative and not very accurate, so we still need to carefully evaluate this data.
According to the opinion of some astronomers, gamma rays will be formed from the product of the merger of two neutron stars, or alternatively, a black hole associated with a neutron star.
Dangers on the planet
This will be followed by the so-called Collapsar model, according to which the core of a massive star ends up collapsing into a black hole in its later stages. These gamma-ray bursts can have a non-negligible planet-wide effect, as they can lead to an increase in ultraviolet radiation at the Earth’s surface.
This will trigger chemical reactions with other elements of the atmosphere such as oxygen and nitrogen, thus reducing ozone (already harassed by climate change) and causing photochemical smog, with the consequent darkening of the sky and blocking natural sunlight.
We just have to wait for more studies on gamma rays, which we’re sure won’t be long in the next few years.
