Towards Unification of Forces

The quest to unify different forces is not from today but from many years ago. The unification is  like a great advancement in physics. So physicist all over world have tried and are trying to achieve this.
The great scientist Issac  Newton in 1687 unified celestial and terrestrial mechanics. He showed that same laws of motion and law of gravitation are applied to earth and other celestial bodies like stars, moon etc,.
Hans Christian Oersted in 1820 and Michael Faraday in 1830 showed that electric and magnetic phenomena are inseparable. Where there is electric field, there is magnetic field and where there is magnetic field, there is electric field. It is known as electromagnetism as a unified domain. 
James clerk Maxwell in 1873 showed that electricity, magnetism and optics inseparable and that is unified them. He  actually showed that light is an electromagnetic wave.
Sheldon Glashow, Abdus Salam, Steven Weinberg in 1979 theorized that weak nuclear force and electromagnetic force are single form of electro-weak force. Carlo Rubia, Simon Vander Meer in  1984 verified experimentally the theory of electro-weak force.
Einstein also attempted to unify gravity and electromagnetism but he couldn't succeed in this.
Even after a some successful and some unsuccessful attempts in the quest of unification of forces, scientists even today are trying  to do this. Yes, it  could take some time but lastly physicists would succeed in it and this would be a great achievement.

Will UY Scuti end in Supernova?

UY Scuti  is a red super-giant star   the constellation Scutum . It is one of the largest star  by radius.   UY Scuti is located a few degrees north of the A - type  star  Gamma Scuti  and northeast of the Eagle Nebula.  UY Scuti is located a few degrees north of the A - type  star  Gamma Scuti  and northeast of the Eagle Nebula . D ue to its distance and location in the Zone of avoidance  within the Cygnus Rift, only it's 9th magnitude is visible . It is c lassified as a semi regular variable with an approximate pulsation period of 740 days.  The star  is over 1,000 times bigger than the our star  and over 100,000 times more luminous than the Sun.It has  a maximum brightness of magnitude  8.29 and a minimum of magnitude 10.56. The star's mass is uncertain because it has no visible companion star by which its mass can be measured through gravitational interference (expected to b...
