This means that light could travel around the Earth seven times in one second! In one year, light travels about six trillion (6,000,000,000,000) miles. The distances to stars and other objects in the Universe are measured in light-years because the distances in space are so huge.

For the first 380,000 years after the Big Bang, however, the intense heat from the universe's creation made it essentially too hot for light to shine. Atoms crashed together with enough force to break up into a dense, opaque plasma of protons, neutrons and electrons that scattered light like fog.

Question 3: You might expect the observable universe to only have a radius of 13.7 billion light years away, because light has only had 13.7 billion years to travel. However, why does our observable universe have an actual radius of about 46 billion light years? (Hint: Click the Observable Universe to aid your reasoning)
