The media has been flooded with rumors todaynetwork about the possible discovery gravitational waves for the first time, by an American team of astrophysicists.
The rumors were sparked by his announcement centreυ αστρονομίας του πανεπιστημίου Χάρβαρντ, πως την ερχόμενη Τρίτη στις 18:00 ώρα Greeces will announce in a press conference a scientific discovery of the greatest importance, without however giving more information.
From that point on, on social media and in the newsgraphics agencies, there was much speculation as to what the discovery might be, with the most imaginative talking about the detection of life in space, but the opinion quickly prevailed that the news would be related to the discovery of gravitational waves, an idea that stems from the Albert Einstein's equations describing space and time.
According to the theory of Relativity, nothing is transmitted faster than the light, and this even applies to forces, such as gravity. Einstein's theory describes gravity through the curvature of space-time caused by mass and energy, and according to it, it is transmitted by gravitational waves, which are essentially wrinkles in the structure of space-time.
Because gravity is a very weak force, the detection of these waves has proven to be a very difficult task, and it is certainly impossible with technical means on Earth.
It has been suggested, however, in the past, that gravitational wave detection could be achieved by studying polarization in background radiation, in the wake of the Great Explosion created by the Universe before 13.8 billions of years.
According to inflation theory, the predominant view of the evolution of the Universe, following the Big Bang followed a brief period where the universe grew exponentially in size. The main predictions of this theory are the imprinting of gravitational waves in the background radiation spectrum, which at the first moments of the Universe was much stronger due to the high energies that prevailed.
Given that Harvard's astronomy center houses the BICEP2 experiment, which is dedicated to studying polarization of background radiation, it is very likely that astrophysicists have identified the gravitational imprint of the early Universe.
If this information is confirmed, it will be one of the most important discoveries of the last century that will surely make sense. Next update will follow on Monday.
