Energy

Light

When we talk about light we usually mean the light we can see with our eyes.

This is also called visible or optical light.

Light is one way energy can be transferred - moved from one place to another.

Relativity

Gravity is the force we are most familiar with in everyday life. It has been studied for longer than the other forces of nature. However, it is also the least well understood.

An image showing many galaxies within a cluster. Towards the centre, the light has curved, appearing to form the outline of a face and a mouth smiling whilst two bright galaxies look like the eyes.

A galaxy cluster appearing to have two eyes and a nose to form a smiley face. The eyes are actually very bright galaxies, and the lines are arcs caused by an effect called gravitational lensing.
