Through the Wormhole: How Does the Universe Work?

With the help of massive machines called particle accelerators, scientists studied the subatomic realm and made discoveries about the forces that operate at that level. But the search for a full explanation continues.

In particular, physicists have tried to find a way to reconcile Einstein’s model of space-time, which seems to work best when applied to large objects like stars and galaxies, and the theory of quantum mechanics, which provides an explanation of electromagnetic and nuclear forces to make sense of reality to the smallest level.

In recent years, some have proposed a new solution called string theory, in which tiny particles are loops that vibrate like violin strings in a multidimensional space.

In the mathematical calculations that make string theory, gravity is a byproduct of the process. While string theory offers a possible solution to the ultimate question of the ages, there is a problem: Scientists have not yet found a way to test the theory experimentally to demonstrate that it is just a smart idea. List of all episodes here: through the hole.
