Black Holes
A Black Hole is a place in space where gravity is so strong and where it pulls so much that not even light or any electromagnetic mave can get out.
This phenomenon can occur when a star is dying becuase matter has been squeezed into a tiny space which makes the gravity so strong.
"Consideration of black holes suggests, not only that God does play dice, but that he sometimes confuses us by throwing them where they can't be seen." - Stephen Hawking
The big bang theory also gives us a scientific explanation as to why we are here today. It suggests that through a process of expansion and explosion hydrogen gas was created which led to the formation of stars, and their death ( a supernova) led to the creation of life.
Albert Einstein and the theroy of relativity
Albert Einstein is one of the greatest and the most well known physicists in the world. He He was born on 14 March 1879 and is most famous for his contributions to physics like his theory of relativity and his development of quantam mechanics. We will focus on relativity descirbing the broad idea that matter causes space to curve.
General relativity
The revolutionary theory of gravity proposed by Albert Einstein in 1915 is known as general relativity. By characterising gravity as the curving of spacetime brought on by large objects, it profoundly redefines how we think about how gravity operates. According to this idea, huge things like planets and stars bend the very structure of the cosmos. Because of this warped spacetime, satellites and even light beams travel along curved pathways, giving the illusion of gravitational attraction. The theory of general relativity has significant ramifications for how we perceive the universe, from foretelling the appearance of black holes to describing how gravity bends light.
