Dark energy and dark matter do not exist as scientists think

Scientists have long assumed that the main components of the universe are (accounting for more than 68%) and (27%), and that planets and stars make up only about 5%. A new study shows that the hypothesis is no longer true .

For almost a century, researchers have assumed that the universe contained more matter than was directly observed. The kind of material that cannot be observed, the factor that makes the stars move is called dark matter, accounting for 27% of the universe. In addition, there is an element in the universe that accelerates the process of accelerating the universe, stronger than gravity, called dark energy, which accounts for 68% of the universe.

Dark energy accounts for 68% of the universe.

However, according to a researcher from the University of Geneva (UNIGE) in Switzerland, the two concepts are no longer reasonable. This group illustrates phenomena without the need for dark matter and dark energy. The study published in The Astrophysical Journal physical journal will likely help us answer two of the biggest mysteries of astronomy.

According to Science Daily, the universe and evolutionary history are characterized by equations in Einstein's general theory of relativity, Newton's universal gravitation and quantum mechanics. The current central universe model is and the expansion (bottom image).

Big bang and expansion.

According to UNIGE André Maeder astronomical professor André Maeder, this traditional model does not take into account an initial hypothesis, which is the scale variation of empty space.

Empty space is the factor that forms Einstein's relatively broad equations, expressed in a so-called quantity. In the old model, its empty space and characteristics will not change with the expansion or contraction of the universe.

Changing the assumption of empty space in the old model from constant to variation, Maeder built and tested three new models : the first model based on Einstein's general theory of relativity, the second based on Newton's gravitational law (a specific version of relatively wide equations), the third experiment looks at the speed dispersion of the orbiting stars (the galaxy has our earth).

1. In the first experiment based on general relativity, the calculation results were consistent with observations. The head model also predicts the accelerating expansion of the universe without the need for dark energy or molecular energy elements.

In summary, the physical equations in the first model based on Maeder's general theory of relativity include accelerating the expansion of the universe , so it may in fact not exist the so-called dark energy.

1. In the second model based on Newton's gravitational law, applied to galactic clusters, this model shows a multitude of galaxy clusters that fit in visible matter, meaning that we can explain the speed. High galaxies in galactic clusters without the need for dark matter. Newton's law of gravitation corrected also predicting how stars would achieve high speed at galactic outer regions without depicting dark matter.
2. In the third experiment focused on the dispersion in the speed of the pulsating stars around the Milky Way plane (often increasing with the age of the stars involved), hypothetical empty space is invariant (not changing) Traditional change has explained very well this speed dispersion. This unique result is something that science has yet to agree on.

Maeder's new discovery will pave the way for a new concept in astronomy.

Maeder's new discovery paves the way for a new concept in astronomy, a concept that is highly controversial and controversial."This model has finally solved two of the greatest mysteries of astronomy. Its publication is still true to the scientific spirit: nothing can forever be obvious, not just in the scriptures. human experience, observation or reasoning , " concluded Professor André Maeder.

Dark matter and dark energy

Dark matter began to be named in the world astronomical dictionary in 1933, when Swiss astronomer Fritz Zwicky had a worldly discovery: the universe had more material than what we saw in reality. sacrifice. By the 1970s, the concept of dark matter became even more important when it was used by American astronomer Vera Rubin to explain the movement and speed of stars. The scientific community then devoted considerable resources to identifying dark matter: on space, on the ground and at CERN (European Nuclear Research Organization), but all failed. In 1998, the world witnessed the second concussion discovery: discovering the acceleration of the expanding universe from a group of Australian and American astrophysicists. This so-called dark energy discovery was awarded the 2011 Nobel Prize in physics.

The universe has more material than what we have seen in reality.

Despite the enormous resources that have been carried out above, there has never been any theory or observation that can define the kind of black energy that is thought to be stronger than Newton's gravity. Since its discovery, dark matter and dark energy have been two mysteries that have challenged astronomers for nearly a century.

Before the UNIGE study above, in April this year, a group of Hungarian scientists published the new cosmological model hypothesis that does not need dark energy . This theory considers the density of the universe to be different, so the expansion of the universe is also different. The calculation results also show that this model is consistent with general relativity and also explains the expansion of the universe without dark energy.
