It explains concepts of physics in the ‘post-newton’ era. There are many topics that fall under this category. This includes topics such as the four fundamental forces, black holes, the string theory and many more. These topics are then further explained into concepts and ideas by many brilliantpeople. All of these topics and the concepts behind them are tied together through string theory. Modern physics is taught today to help this generation get an understanding of physics.The big bang theory is the theory about how the universe came to be. The concept explains that how 13.73 billion years ago, the universe was created. The theory explains how a small hot ball of matter and atoms developed and grew. These atoms eventually grew extremely hot in temperature and the atoms burst. The expansion then created the plant we have today. Thisthen led to may more of the modern physics concepts we have today.The next concept to come was the four fundamental forces. This includes gravity, electromagnetism, strong interaction, and weak interaction. Gravity was discovered in 1643 by Sir Isaac Newton. Gravity is the force that holds us and everything around us to the ground. It is a magnetic force that attracts things together. Later, in 1820, Hans Christian Oersted discovered electromagnetism.Electromagnetism is the force created by interactions between positives and negatives. Electromagnetism is then broken up into two parts, electrostatic forces and magnetic forces. Electrostatic forces are when the particles are charged and are then able to build up in objects and travel. These forces create commonly known things such as lightning. Magnetic forces is when the interactions create a magnetic field. The next fundamental force was founded by Eugene Wigner in 1933. This was the discovery of strong interactions. Strong interactions is what holds things together. Where there is strong interactions there must also be weak interactions. This is the force that pulls things apart. The concept was developed by Enrico Fermiin 1933 after Eugene Wigner.
