The most MYSTERIOUS Matter in the UNIVERSE- The Dark Matter

INTRODUCTION 

What we can observe in our sky - planets, stars, gas, dust, galaxies, nebulae, asteroids, meteors, and more-is a small fraction of what exists. Bright matter, the visible stuff of the universe, forms only about one- sixth of its mass.
What forms the rest, and how do we know it's there?
So, in this blog I am going to share some factual information about dark energy and dark matter of the universe as these are the most mysterious things in the universe!


Dark Matter

Scientists know there must be more out there than meets the eye because the unseen substance has gravity and appears to be holding together the parts of the universe that we can see, galaxies in particular. Because the unseen matter doesn't emit any radiation, scientists call it as Dark Matter
Believed to constitute about 95% of the universe's total mass, dark matter and dark energy may comprise unfathomable numbers of tiny sub-atomic particles. Candidates for dark matter include Cold Dark Matter (CDM), sluggish elementary particles, Weakly Interacting Massive Particles (WIMPS) heavy hypothetical particles that rarely interact with other matter; and Massive Compact Halo Objects (MACHOS), known objects such as planets, neutron stars, and white dwarfs that are presumed to be in the halos of galaxies
so, we can conclude that Dark Matter is an unknown substance detected only by gravity it exerts and makes up most of the universe's total mass.



Dark Energy

Now moving on to the next topic, i.e., DARK ENERGY; Scientists have given the name dark energy to the expansion generating force or substance of the universe. Dark energy is the reverse of gravity; It pushes things away rather than pulling them together. It is unknown whether the laws of physics or the general theory of relativity can account for dark energy.
In 1998 astronomers studying supernovae found them dimmer than anticipated. This meant both they were farther away and the universe was expanding faster than expected.
The U.S. government's Joint Dark Energy Mission (JDEM) examined Type la supernovae, dying white dwarfs, because of their high and consistent luminosity. The program ended in 2010, and will be replaced by Wide-Field Infrared Survey Telescope (WFIRST).

CONCLUSION

So, keeping the post short and sweet, I will end this post now.
So, I think you must've got some idea about dark energy and dark matter and ya also you can't understand the whole thing in just a day and no one can explain the complete topic.
So, write down in comments about how was the post and suggest some topics related to black holes and time travel as this blog is completely dedicated to black holes and other topics around it.

BLACK HOLES Introduction In this blog post, I am gonna tell you almost everything about what are black holes, how they are formed, how they can affect us, some myths about them and how they react with other objects in the universe. So, just grab a coffee, sit back and read the blog completely and enjoy this journey of life cycle of a black hole. What exactly are Black Holes? The term Black Holes is of exceptionally late source. It was coined in 1969 by the  American researcher John Wheeler as a realistic portrayal of a thought that returns in any event every 200 years. Around then there were two speculations about light. One was that it was made out of particles; the other one was that it was made of waves. We presently realize that truly the two speculations are correct. By the wave/molecule duality of quantum mechanics, light can be viewed as both a  wave and a molecule. Under the hypothesis that light was comprised of waves, it was not satisfactory how it would react to gravity. Be

Newtonian Gravity v/s Einstein's Gravity

INTRODUCTION This is just a factual blog of basic differences between newton's theory and einstein's theory about gravitation and it will give you a basic idea of both the theories Newton's Gravitational theory  In the 17th century, Sir Issac Newton gave his law of gravitation suggesting that gravitation is a force that holds two objects together like the earth's gravitational field holds the moon in its position, and similarly, the sun holds the planets in their respective positions as we see them and he said that the gravitational force is directly proportional to the product of the masses of the two bodies and inversely proportional to the square of the distance between them and gave the famous formula for calculating the gravitational force between two bodies, i.e., F= GMm/r^2 where G is a proportionality constant and its value is 6.67*10^(-11) Nm^2/kg^2 as given by Sir Henry Cavendish by his experiment which he performed in 1798, he used a torsion balance to d

  THE BERMUDA TRIANGLE INTRODUCTION In this blog post, I am going to brief you about this amazing mysterious thing known as Bermuda triangle , and I am pretty sure, most of you must have an overview about what it is but I will actually explain almost everything about this realistic geometrical shape; So, enjoy reading the blog with a nice cup of coffee. BERMUDA TRIANGLE, What is it? The Bermuda Triangle which is also sometimes called as ' The Devil's Triangle ' is a place about which no one would like to go as it swallows you like anything; Scared!, you should as it is a place of which you should have the fear, so, getting back to topic, It is actually a merely defined place situated in the Western Part of the North Atlantic Ocean where many aircrafts and ships are said to have disappeared under very mysterious and unknown circumstances. The area of the Bermuda Triangle is among the most vigorously voyaged dispatching paths on the planet, with ships often getting through it
