Wild New Theory Suggests Gravitational Waves Shaped The Universe
Just as the ocean waves shape our shores, the fluctuations in space-time may have put the universe in an evolutionary path that caused the cosmos, as we have seen today.
Proposes a new theory gravity waves – Instead of the hypothetical particles called inflaton – he continued to expand the universe and redistribute the substance there.
“For decades, we have tried to understand the first moments of the universe using models based on elements that we have never observed,” Theoretical astrophysicist explains the first author of Jiménez University of Barcelona.
“What excites this offer is its simplicity and verification.

We do not know exactly how the earliest stages of the universe emerged. Large explosion 13.8 billion years ago. At this point, all scientists they can do come with the theories that match the physique of the universe we observe.
These theories are quite good, but there are clear deficiencies. Accept JWST’s discovery Numerous Great Gelada For example, in the universe, cosmologists are earlier than they expect.
The currently accepted timeline of the evolution of the universe includes a rapid expansion or inflation period immediately after the big explosion. From a one-dimensional infinite intensity point-the mathematical definition of the universe just before the big explosion-the universe was rapidly inflated, inflated with a hot plasma soup that cools for substance.
Inflaton is a speculative particle or quantum field that scientists use to explain the amazing smoothness of cosmological inflation and cosmos. In theory, the particle finally guides the rapid expansion of the universe while allowing variations with the intensity of the plasma soup. black holesGalaxies, stars and all other lice and bobs of matter are scattered into the universe.
However, despite our best efforts, physicists I could not find any other evidence This supports the presence of inflato. Jiménez and his colleagues wanted to know if there was another way – if we could explain the early evolution of the universe using different parameters that rely on speculative elements.
They started with a very simplified model of the real universe. general relativity And current observations of the expansion of the universe, Also sitter area. In this area, quantum fluctuations in space-time-that is, gravity waves It is produced by a turbulence type called tensor perturbations.

Gravity waves are thought to fill the universe today. They are fluctuations produced with great interruptions at space time. It is produced with collisions between large, dense objects such as neutron stars and black holes, which we can detect right now, but physicists believe The whole universe is playing With a fixed background, it is very large (yet) for us to detect gravity waves.
Researchers have found that gravity waves produced by tensor perturbations in space-time models can create intensity variations on their own in primordial plasma and allow the universe to expand early.
In the end, these variations will collapse under gravity and will create intense clusters to form the seeds of the early universe – the first stars and galaxies and black holes.
This is a very elegant solution, of course, although more work is needed to verify, it eliminates its confidence in assumptions as a driving force behind the early evolution of the whole universe.
However, “Our recommended mechanism can eliminate the need for a scenario -related scenario: the choice of a scalar area to direct inflation as an inflator” Researchers Write.
