WAY OF THE END OF THE UNIVERSE


1.BIG CRUNCH 

          
         big crunch is one of the reasons for the end of our universe.According to this theory, the universe will one day stop expanding. Then, as gravity pulls on the matter, the universe will begin to contract, falling inward until it has collapsed back into a super-hot, super-dense singularity.It starts out small, then expands as it heats.

          Big crunch theory depends upon critical density of the universe.

2.BIG RIP

          the Big Rip is a hypothetical cosmological model concerning the ultimate fate of the universe, in which the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe at a certain time in the future.

          at that time all the galaxies,stars,planets even protons and electrons will go away from one another.



3.BIG FREEZE
         The big freeze, which is also known as the Heat Death, is one of the possible scenarios predicted by scientists in which the Universe may end. It is a direct consequence of an ever expanding universe.

          according this theory the entropy will continuously increase until it reaches a maximum value. The moment that happens, heat in the system will be evenly distributed, allowing no room for usable energy or heat to exist.

WHAT HAPPENED DURING FIRST SECOND OF BIG BANG??

FIRST SECOND OF BIG BANG           At 1 x 10 -43  seconds,            the universe was incredibly small, dense and hot. This homogeneous area of the universe spanned a region of only  3.9 x 10 -34  inches. During this phase, big bang theorists believe, matter and energy were inseparable.The four primary forces of the universe were also a united force.at that time  The temperature of this universe was 1 x 10 32  degrees Kelvin.the quark particles was made during this phase.   At 1 x 10 -35  seconds,           as universe expanded,its cooled and energy and matter decoupled. the universe filled with a nearly equal amount of matter and anti-matter. There was more matter than anti-matter, so while most particles and anti-particles annihilated each other, some particles survived. These particles would later combine to form all the matter in the universe.so...

ELECTROMAGNETIC FIELD OF EARTH INTRODUCTION                      The motions of the liquid iron and nickel outer core of the earth are thought to create the earth’s magnetic field. This magnetic field resembles a dipole as if a giant bar magnet was embedded inside. However, the axis of the dipole is not aligned with the rotational axis of the earth. Neither is it centered in the earth. EARTH'S MAGNETIC FIELDS PROTECT US FROM SOLAR WIND AND SPACE RADIATION.            The Sun is a burning ball of gas that reaches such extreme temperatures that gas flies out from it at very high speeds. In fact, many of the electrons in the Sun’s atoms have enough energy to actually leave the atoms. The abandoned charged atoms are called ions. These ions and electrons flow outward from the Sun, and together they are known as the solar wind.           When the solar wind travels with...

OUR NEIGHBOR,ANDROMEDA GALAXY

OUR CLOSEST GALAXY ANDROMEDA..                 Andromeda  is the largest galaxy in the Local Group, which includes the Milky Way, the Triangulum Galaxy, and dozens of smaller dwarf and irregular galaxies. A recent estimate gave Andromeda 700 billion solar masses. Our Milky Way is only 80% the mass of Andromeda. IMAGE BY :  jpl.nasa.gov                  The Andromeda galaxy was first observed by Persian astronomers, thousands of years ago, and was later cataloged by Charles Messier in 1764. He classified it as M31. In 1912, astronomers calculated its speed to be 300 kilometers per second, moving towards the Sun. Edwin Hubble first calculated the distance to Andromeda, by detecting Cepheid variables in the galaxy. He measured that it was 450 kpc, or 2.5 million light-years away; well outside the Milky Way galaxy.                Rec...
