Life cycle of a star Every star has a life cycle just like a human or a frog except stars do it on a much larger scale. Stars start life as a massive cloud of matter and then get pulled together to create a star. But stars do not last forever most stars last for millions of years but they still end. When a stars life ends it may explode or implode to create a black hole. The reason stars even start life and end life is because of nuclear fusion. Nuclear fusion is a reaction where matter is forced

The Other Side of Einstein Albert Einstein‚ arguably the greatest scientist and mathematician of all time‚ is mostly known for his prominent scientific discoveries and achievements. He is often perceived by the public as a scientist who lived his life in his laboratory studying‚ void of any social life. However‚ in the essay "My Friend‚ Albert Einstein" by Banesh Hoffmann‚ Einstein’s long time friend attempts to depict Einstein as a humble and compassionate man‚ contrary to the mythological figure

This is in contrast to ordinary quantum field theory‚ which predicts point particles that emit and absorb each other. String theory is a candidate for a Theory of Everything." String theory would solve the long fight between Einstein’s theory of relativity and Quantum Physics. String theory proclaims that everything in our universe‚ from stars and suns to apples and atoms‚ is made up of incredibly small particles called strings. Strings are so small‚ that if an atom were the size of our solar system

Those who truly know us for who we really are; are the people that have the most influence in our lives‚ such as our parents. In my case it is my mother who has greatly impacted my life. She has stood beside me through thick and thin. I know that as long as she is here on this earth‚ she will stand beside me to love and support me unconditionally as she has done all these years. It is because of her that I am the person I am today. Behind my choices‚ character‚ my values‚ and behind me‚ proudly stands

gravity has on light. He is now credited for being the first to consider the case of a supermassive object that prevents light from escaping. He called these objects “dark stars”‚ which we now know as black holes. With later knowledge of the theory of relativity‚ scientists were able to find out that when so much matter is concentrated in a small region‚ gravitational forces are so strong and space so extremely warped that light is no longer just being bent‚ but trapped inside the object (see image on the

far‚ so good: Einstein’s equations predict the shape of the moon’s orbit as well as laser ranging can measure it. But Einstein‚ constantly tested‚ isn’t out of the woods yet. Some physicists (Alley is one of them) believe his general theory of relativity is flawed. If there is a flaw‚ lunar laser ranging might yet find it.” This experiment is now being used to check the theories of many of the astronomers throughout history Sources: http://www.nasa.gov/vision/space/features/21jul_llr.html http://nssdc
