As an object moves, it's mass increases, and time goes slower for the object. Exactly determining the position and momentum of an object is impossible. A particle is mostly here, but partially there, and partially somewhere else. A vacuum consists of electrons with negative mass. In vacuum, particles appear out of nothing for a very short period of time and then disappear. These statements seem absurd from the common point of view, but in fact they are very real and can be easily proven by experiments and by the laws of modern physics.
In Newtonian physics, everything is simple. Newton said "Absolute space in it's own nature, without relation to anything external, remains always similar and unmovable."" He also asserted in the principia, "Absolute true and mathematical time, of itself, and from it's own nature flows equably without relation to anything external, remains always similar and immovable-. The physics Newton built was based on three main ideas: Newton's first law (Galileo's principle of inertia) stating that an object at rest tends to remain at rest unless acted on by an external force; Galilean transformation of inertial frames: (Krane 18), and the law of conservation of momentum (Halliday 237). .
These ideas seemed self-evident and no one even tried to doubt them, until two American scientists, Micheleson and Moorly performed an experiment in which they discovered that the speed of light is the same to any moving object traveling at any speed in any direction. This means that if someone measures the speed of light from the sun when traveling away from the sun at one mile per hour, or traveling at 500000 kilometers per second, the two measurements would be the same. This has a very unusual consequence. Consider this experiment. A person A is observing a train traveling close to the speed of light. Person B is traveling in the train. Person B sends a beam of light from the floor to the ceiling and it reflects back down.
