We cover string theory and M-theory, which are at the forefront of modern physics, and furthermore, we reveal the structure of the universe, including parallel universes. Physicists have a common dream. To prove that seemingly different phenomena are essentially the same. To find a single ultimate theory. Newton discovered that the reason apples fall and the moon orbit the Earth is the same. Maxwell discovered that electromagnetic phenomena and light are essentially the same. Einstein combined time and space. The world we experience can now be explained by a single theory. The dream of physics, which seemed to be going smoothly, lost its way with the advent of quantum mechanics. The laws that move the large world and the laws that move the small world could not easily be combined. What emerged to combine the two theories was 'string theory'. The smallest unit of all things is not a particle, but a small, vibrating string. Is everything in the world really made of strings? Do strings actually exist? Can string theory fulfill the dreams of physicists? We follow the process of finding a single theory, the supreme task of physics, and examine the current state of physics and the remaining tasks. #Einstein #Newton #Quantum mechanics #Universal gravitation #Theory of relativity #Maxwell #String theory ▶️ Program: Physics of light Part 6 - Light and strings ▶️ Broadcast date: 2013.10.02
