Exploration of gravitational waves;

With rumors, the internet has been flooded today about the possible discovery of gravitational waves for the first time by an American group of astrophysicists.

The rumors were sparked by the center's announcement of Harvard University, that next Tuesday at 18:00 Greek time he will announce in a press conference a scientific discovery of the greatest importance, without, however, giving any more information.

From that point on, there was much speculation on social media and news outlets as to what the discovery might be, with the most imaginative talking about life in , but the opinion quickly prevailed that the news would be related to the discovery of gravitational waves, an idea derived from 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.

But it has been suggested in the past that the detection of gravitational waves could be achieved by studying the polarization in the background radiation, the aftermath of the Big Bang that created the Universe 13.8 billion years ago. years.

According to inflationary theory, the prevailing view of the evolution of the Universe, the Big Bang was followed by a brief period in which the Universe grew exponentially in size. One of the main predictions of this theory is the imprinting of gravitational waves in the background radiation spectrum, which in the first moments of the Universe were much stronger due to the high 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.

Εάν επιβεβαιωθεί αυτή η πληροφορία, θα πρόκειται για μία από τις σημαντικότερες ανακαλύψεις του τελευταίου αιώνα, που ασφαλώς θα δημιουργήσει αίσθηση. Επόμενη will follow on Monday.
