The horizon problem results from the premise that information cannot travel faster than light.

Lines then indicate how the information travels from one system to another.

Now information travels at the speed of light into almost every home on the planet.

Electromagnetic information about the charge travels at the speed of light.

This means that information can travel faster than the speed of light, which Einstein says is not possible.

We'll take a closer look at protocols and how information travels across the Internet on the next page.

In standard physical theories, no information can travel faster than the speed of light.

All the information that we receive from the stars travels at the speed of light and no faster.

Clearly the information traveled the other way: you knew that I might come here tonight.

This can occur when information is traveling through various people within a network.
