Abstract
Our Milky Way gives the impression to be rooted in an extended dark matter halo, that is require to create a gravity in order to hold the stars and gas in the galaxy together and act like a binding force, although its presence is not hidden from the world, this paper mainly focuses on strengthening it more, considering the growth and gigantic experimental, and observational progress. As all the evidence are indirect and purely based upon gravitational effects of dark matter. Herein we will be discussing different front and opinion that astronomers have formed in order to define the presence of dark matter. Keywords: Dark Matter, Astronomers, Galaxy, Astro-Physics
Introduction
Dark energy is assumed to be a property of space that bumpily constitute 68% of the universe. Whereas, dark matter set up about 27% and all the other things on earth, all of the normal matter adds up to not more than 5% of the universe.
Some theories remains suggestive of dark energy being a new kind of dynamical energy fluid or field that supposedly fills all parts of space but has inverse action on expansion of the universe and is different from dark matter and normal energy.
What is dark matter?
Dark matter and Rubin rotational curve. Dark matter is a not known form of matter, it appears only when taking part in gravitational interaction, and neither does it emit nor absorb electromagnetic radiations.
It was first proposed in the year 1932 by Jan Oort a Holland astronomer, who noticed that the orbital paces or velocity of stars did not match their measure masses.
Explaining in layman language, it is basically an invisible substance that is as underlying scaffolding on which galaxies are built. More explanatory it is that glue which holds the visible matter in galaxies like star and gas together.
