Today I will discuss what is theory of special relativity.
But Lei, what is that?
Slide: 3
Special relativity is an explanation of how speed affects mass, time and space. The theory includes a way for the speed of light to define the relationship between energy and matter, small amounts of mass (m) can be interchangeable with enormous amounts of energy (E), as defined by the classic equation E = mc^2.

Special relativity applies to special cases it's mostly used when discussing huge energies, ultra-fast speeds and astronomical distances, all without the complications of gravity. I officially added gravity to my theories in 1915, with the publication of my paper on general relativity.

As an object approaches the speed of light, the object's mass becomes infinite and so does the energy required to move it. That means it is impossible for any matter to go faster than light travels. This cosmic speed limit inspires new realms of physics and science fiction, as people consider travel across vast distances.

Special relativity: It's like normal relativity, but special.
