The Basic Elements of String Theory

Five key ideas are at the heart of string theory. Become familiar with these key elements of string theory right off the bat. Read on for the very basics of these five ideas of string theory in the sections [more…]

What String Theory Attempts to Accomplish


The Successes of String Theory

String theory has gone through many transformations since its origins in 1968 when it was hoped to be a model of certain types of particle collisions. It initially failed at that goal, but in the 40 years [more…]

Considering String Theory’s Setbacks

Because string theory has made so few specific predictions, it’s hard to disprove it, but the theory has fallen short of some of the hype about how it will be a fundamental theory to explain all the physics [more…]

Einstein's Special Relativity

In 1905, Albert Einstein published the theory of special relativity, which explains how to interpret motion between different inertial frames of reference [more…]

Einstein's General Relativity Theory: Gravity as Acceleration

General relativity was Einstein’s theory of gravity, published in 1915, which extended special relativity to take into account non-inertial frames of reference [more…]

Einstein's General Relativity Theory: Gravity as Geometry


String Theory's Idea of an Expanding Universe


String Theory's Notions of The Big Bang Theory

Soon after astronomer Edwin Hubble proved the universe was expanding, it became evident that the universe was once very much smaller. The theory that the universe started from a single point [more…]

The Universe's Dark Matter and Dark Energy

Two of the biggest mysteries of both string theory and cosmology are the presence of unseen dark matter and of repulsive gravity in the form of dark energy. [more…]

String Theory: Defining a Black Hole

One of the consequences of Einstein’s general theory of relativity was a solution in which space-time curved so much that even a beam of light became trapped. These solutions became called [more…]

The Start of the Universe with String Theory

The big bang theory doesn’t offer any explanation for what started the original expansion of the universe. This is a major theoretical question for cosmologists, and many are applying the concepts of string [more…]

String Theory and the Thermodynamics of a Black Hole


String Theory and the Black Hole Information Paradox


The Theory of Parallel Universes


Slowing Time to a Standstill with Relativity

In physics, time travel is closely linked to Einstein’s theory of relativity, which allows motion in space to actually alter the flow of time. This effect is known as [more…]

General Relativity and Wormholes: Doorways in Space and Time

In general relativity, the fabric of space-time can occasionally allow for worldlines that create a closed timelike curve,which is relativity-speak for time travel. Einstein himself explored these concepts [more…]
