We know that ordinary matter is made just 5% of the universe like atoms which make
galaxies, stars and planets. The rest of the universe is dark and unknown, composed of dark
matter and dark energy. Invisible dark matter makes up 27% of the universe and dark energy
makes up 72% of the total mass-energy density of the universe. Currently, many experiments
around the world are searching for dark matter and dark energy to solve the mystery of them
and understand their properties.
In this paper we define a new way to explain what dark matter and dark energy really are.
The mass, by definition, is a measure of resistance of an object to acceleration when a force is
And, in principle, the mass occupies space and it is there where the force takes effect. Given
what has been said, Dark Matter does not meet the definition of mass. Because it is everywhere
but we can't find it. Indeed, what is called Dark Matter is an illusionary definition that must be
corrected. Actually there is no Dark Matter, but rather a Vivid Force whose effect holds the
structure of galaxies. According to the current theory the Dark Matter effect exists everywhere
but it cannot be seen, so it is a force and not a mass. It is called Dark because the science has no
knowledge about its nature; the one that we are going to explain and that we can call the Vivid
On the other hand, Saleh Theory believes that a miscalculation happened in the estimation of
released primary Energy of the Big Bang and if it is calculated by Energy density, there is no
need to define an unknown energy which called Dark Energy.
