The physics king Hawking talks about dark matter

The British genius physicist believes that the next breakthrough in physics will happen in the field of dark matter and dark energy research.

>>>Stephen Hawking: "Humanity has 1000 years to escape the Earth"

World-renowned physicist Stephen Hawking, in his lecture on The Origin of the Universe at the California Institute of Technology in Pasadena (USA), said the area of ​​expertise is expected to bring scientific breakthroughs. learn.

Mr. Hawking told the Los Angeles Times newspaper: "A link that cosmology has not yet discovered is the nature of dark matter and dark energy. Ordinary matter accounts for only 5% of the universe and the remaining 27% is dark matter and 67% dark energy '.

The nature of dark energy and dark matter is one of the greatest mysteries of modern science. Dark matter is a hypothesis, first appearing in the work of theoretical physicists in the 70s of the last century to explain the unusual distribution of the speed of movement of stars. and gases in the galaxy.

Their research results have demonstrated that this motion occurs under the influence of strong gravity, and cannot be explained by visible matter.

Dark matter increases the mass of galaxies. It does not emit, does not absorb and does not reflect light. According to an acknowledged hypothesis, it fills the solar system galaxy and, of course, part of it passes through the Earth.

Dark energy, which cannot be measured directly, is making the universe expand. Scientists believe that without dark energy, under the influence of gravity, the universe will "explode".
