Lorentz boosts are a fundamental concept in special relativity, describing the transformation of spacetime coordinates when an observer changes their velocity. Imagine two observers, one at rest and another moving at a constant velocity relative to the first. A Lorentz boost is the mathematical operation that relates the measurements of space and time made by these two observers. Unlike the Galilean transformations of classical physics, which assume absolute time, Lorentz boosts demonstrate that time is relative and depends on the observer's motion. Specifically, they show that time intervals can appear to pass slower for a moving observer (time dilation) and lengths can appear contracted in the direction of motion (length contraction) when viewed from the perspective of a stationary observer.

The mathematics behind Lorentz boosts involves a set of linear equations that transform the spacetime coordinates (typically denoted as t, x, y, z) from one inertial frame to another. The extent of the boost depends on the relative velocity between the frames. As the relative velocity approaches the speed of light, the effects of time dilation and length contraction become increasingly pronounced, approaching infinity and zero respectively. Lorentz boosts are a crucial component in understanding phenomena such as the behavior of particles in accelerators and the relativistic effects observed in astrophysics. They are also intimately connected to the concept of spacetime intervals, which are invariant under Lorentz transformations, meaning that the distance between two events in spacetime is the same for all inertial observers, regardless of their relative velocity. This invariance is a cornerstone of special relativity.
