Gw mau tau Time in modern physics dari Waktu. Jelasin dalam bahasa sunda

In the late nineteenth century, physicists encountered problems with the classical understanding of time, in connection with the behavior of electricity and magnetism.  Einstein resolved these problems by invoking a method of synchronizing clocks using the constant, finite speed of light as the maximum signal velocity.  This led directly to the result that time appéars to elapse at different rates relative to different observers in motion relative to one another.
