Milkyway's End

        Everything that has a start has an end too. The final state or the destiny or the future of a living organism, star, galaxy and the universe has, is to die as all involves life. The end in many cases can be predicted but its accuracy is proved only by time. With great efforts combined by the masters of Physics throughout the world, a picture of how our MILKYWAY galaxy, which is also known as AKASHGANGA will end in the time frame yielding a new galaxy.

        With the advancement in technology, we have figured out the answer to our galaxy's end. As per the experiments, physicists believe that our galaxy would die due to its collision with another galaxy heading towards it. The collision will not take place in a day or a year, rather it will be a process of many centuries. It is predicted that the galaxies would cross each other by side many times and will eventually form a new galaxy with a new black hole at its center. The velocity with which milkyway is heading is nearly 4,00,000 Km/hr yet its collision time is a lot ahead; somewhere around 5 to 6 billion years. Fortunately we will not see our galaxy dieing in front of our eyes and we being getting shrunk in the distance.

Death of Earth

        One of the exciting questions of the ancient times was about the death of our own planet Earth. Scientists all over the world struggled long enough to gather information to predict the fate of Earth. Given a choice between two- Death of Earth in ice or fire, scientists bantered each other with their theories and research work. Many theories were tossed out. The plausible answer to this question appears to be death of Earth in fire.
        It is now known that the source of energy of a star is the fission or fusion process taking place continuously. In our sun, fusion takes place in the core. It is believed that once our sun has used up its available hydrogen, then the sun will use the unburned helium which will expand into a red giant star. The size of this giant star is presumed to be as large as the orbit of Mars by Sir Michio Kaku. Consequently, the Earth is supposed to be vaporised by this event and hence will be the fate of our planet. But we need not worry about its end as we won't be there to witness the disaster.
