As you know, our vast Universe was born about 14.5 billion years ago as a result of the Big Bang. Despite the fact that we already know a lot about how exactly our universe arose, we still do not understand what exactly caused this explosion, colossal in power. In order to try to answer this question, the researchers decided to analyze the mechanisms that could cause such an incredibly powerful explosion that gave rise to everything, including you and me.
What triggered the Big Bang?
What was the beginning of our universe with you? Well, there are several different points of view regarding the origin of our universe. Some researchers believe that the Big Bang could have resulted from a series of smaller explosions, while opponents of this theory argue that there was literally nothing before it; still others prove that before the birth of our Universe, at least two more Universes existed, colliding with each other and releasing as a result of their collision a large amount of energy, which gave birth to our universe. When scientists announced the discovery of the so-called relic radiation in July 1965, the discovery became truly sensational, laying the foundation for the development of cosmology and the theory of the birth of the Universe, followed by its expansion and cooling.
According to phys.org portal, the researchers managed to find some critical criteria that could cause the primary flame to generate its own turbulence, and then spontaneously accelerate and smoothly turn into detonation. Karim Ahmed, associate professor of mechanics and aerospace engineering at the University of South Florida, believes that the birth of our universe was similar to a supernova explosion, with the only difference that the scales of these cosmic events are disproportionately different.
When, in the process of dying, the parent star gradually burns out, at the final stage of its cosmic death it explodes, leaving behind only a shell consisting of a mixture of various gases and matter. A similar process, albeit much smaller, was carried out by the team of Karim Ahmed in laboratory conditions. The key to the success of the experiment was the use of a certain combination of turbulence and passively burning flame. The powerful explosion that occurred at the end of the process could become similar to the Big Bang that gave birth to our Universe.
The researchers believe that their proposed Big Bang mechanism could help better understand the age of the universe. In addition, experience could help for more efficient operation of hypersonic engines and for modernized power generation.
