Answer 1

it is already known that our universe does not make by atom fully...a huge part does make by dark material...what is dark material???

Solution:

Dark matter is a type of matter hypothesized to account for a large part of the total mass in the universe. Dark matter cannot be seen directly with telescopes; evidently it neither emits nor absorbs light or other electromagnetic radiation at any significant level. Instead, its existence and properties are inferred from its gravitational effects on visible matter, radiation, and the large-scale structure of the universe. According to the Planck mission team, and based on the standard model of cosmology, the total mass-energy of the universe contains $4.9\%$ ordinary matter, $26.8\%$ dark matter and $68.3\%$ dark energy. Thus, dark matter is estimated to constitute $84.5\%$ of the total matter in the universe and $26.8\%$ of the total content of the universe.

Dark matter's existence is inferred from gravitational effects on visible matter and gravitational lensing of background radiation, and was originally hypothesized to account for discrepancies between calculations of the mass of galaxies, clusters of galaxies and the entire universe made through dynamical and general relativistic means, and calculations based on the mass of the visible "luminous" matter these objects contain: stars and the gas and dust of the interstellar and intergalactic medium.
