Special relativity.

Explanation:

Einstein's general theory of special relativity describes the relationship

between energy and matter, and is major event in the history

of science.

In 1905, Albert Einstein a noble physicist developed a theory that forms part of the basis of modern physics and one of the major event in the history of science, this theory was known as the theory of special relativity.

The theory of special relativity gives the relationship between space and time for any object that is moving at a uniform speed in a straight line, typically at the speed of light.

Simply stated, the theory of special relativity describes how a change in the speed of an object affect or relate with the measurement of space, time and mass. This ultimately implies that, as an object approach the value of light speed, it gains an infinite amount of mass and as such it is unable to travel faster than light.

The theory of special relativity by Albert Einstein gave birth to one of the most famous equation in science;

The equation illustrates, Energy equals mass multiplied by the square of the speed of light.

Where; E = Energy.

M = Mass.

C = Speed of light.

From the above equation, we can deduce that the mass of an object increases with speed and that mass is equivalent to energy, thus matter (mass) can be interchanged with energy.
