deep, frozen versions of our solar system. In the sky, they look like this. We know them for their tails. There are actually two tails. One is a dust tail, which is blown away by the solar wind. The other one is an ion tail, which is charged particles, and they follow the magnetic field in the solar system.

The universe is bustling with matter and energy. Even in the vast apparent emptiness of intergalactic space, there's one hydrogen atom per cubic meter. That's not the mention a barrage of particles and electromagnetic radiation passing every which way from stars, galaxies, and into black holes.

electrons, protons, quarks, neutrinos, that make up you and me. However, recent theories in physics, including one called string theory, are now telling us there could be countless other universes built on different types of particles, with different properties, obeying different laws.

But we know it's out there because we can observe its gravitational attraction on galaxies and other celestial objects. We've yet to directly observe dark matter, but scientists theorize that we may actually be able to create it in the most powerful particle collider in the world.

Actually, yes. Using particle accelerators, we can mimic the complex nuclear reactions that create gold in stars. But these machines can only construct gold atom by atom. So it would take almost the age of the universe to produce one gram

Einstein and his colleagues called this strange communcation spooky action at a distance. While it does seem that entanglement between two particles helps transfer a qubit instantaneously across the space between them, there's a catch.

Brian Greene
American Physicist
The full name of string theory is really superstring theory. The 'super' stands for this feature called supersymmetry, which, without getting into any details, predicts that for every known particle in the world, there should be a partner particle, the so-called supersymmetric partner.

Indian Physicist
I work in string theory. This is a branch of physics which assumes that the elementary objects in the universe are not particles but one-dimensional objects, that is, strings.

Sheldon Lee Glashow
American Physicist
People want to know about what's going on with what's in the universe, what are particles like, what are the basic rules of nature. It's a lot of curiosity out there.

Ernest Walton
Irish Physicist
As the size of cyclotrons increases and faster particles are produced, a difficulty arises due to the relativistic increase of mass of the particle.

Most gravity has no known origin. Is it some exotic particle? Nobody knows. Is dark energy responsible for expansion of the universe? Nobody knows.

Enthusiasm is the divine particle in our composition: with it we are great, generous, and true; without it, we are little, false, and mean.
