相对论xiāngduìlùn研究时间和空间相对关系的物理学说。分为狭义相对论和广义相对论。前者认为物体的运动是相对的,光速不因光源的运动而改变,物体的质量与能量的关系为E=mc2(E代表能量,m代表质量,c代表光速)。后者认为物质的运动是物质引力场派生的,光在引力场中传播因受引力场的影响而改变方向。相对论是爱因斯坦(Albert Einstein)提出的。这个理论修正了从牛顿以来对空间、时间、引力三者互相割裂的看法以及运动规律永恒不变的看法,从而奠定了现代物理学的基础。{theory of relativity theory of physics dealing with the relative relationship between time and space, including the special theory of relativity and the general theory of relativity. The former states that there is only relative motion of matter, that the velocity of light is constant and not dependent on the motion of its source, and that the relationship between the mass and energy is E=mc2 (E represents energy, m represents mass, and c represents velocity). The latter states that motion is derived from the gravitational field, and the transmission of light in the gravitational field changes its direction under the effect of the gravitational field. The theory of relativity was advanced by Albert Einstein, who revised the prevailing views since Isaac Newton that space, time and gravitation are separated and that the law of motion is constant, thus laying the foundation for modern physics.} |
