The Synthesis of "string theory"

What is string theory? Discover the framework that unifies physics by describing particles as tiny, vibrating strings in extra dimensions.

Explore Einstein's theory of general relativity, which describes gravity not as a force, but as the curvature of spacetime by mass and energy.

Unpack the multiverse theory: the mind-bending idea that our universe is just one of many co-existing parallel worlds. What does science say?

Discover gravity, the fundamental force that shapes our universe, from falling apples to the orbits of planets. Learn how it holds everything together.

Explore Einstein's theory of relativity. Learn how space, time, and gravity are linked and how E=mc² changed our understanding of the universe.

An overview of the Standard Model of particle physics, the theory describing the universe's most basic building blocks and fundamental forces.

Discover the Big Bang Theory, the leading scientific model for how the universe began from a hot, dense state and expanded into what we see today.

Explore the concept of a singularity, a point in spacetime where gravity is infinite, found at the center of black holes and the origin of the universe.
