quantum theory

According to quantum theory, when not observed, particles such as electrons and positrons exist not at precise points in space but rather as spread-out "clouds" of probable positions. And yet, an electron and positron will collide and annihilate as if they exist as discrete point-like...

A Quantum Mechanical Interpretation of the Consequences of Special Relativity Einstein's theory of Special Relativity Einstein's theory of Special Relativity predicts that for objects travelling at a significant fraction of the speed of light time dilates. Experimental observations are in...
