Some of the furthest galaxies are believed to be "travelling" faster than the speed of light. They are not actually "travelling" faster than the speed of light, but creating space, faster than the speed of light.
8 billion light years means that the light has taken 8 billion years to reach you. That's how far into the past you are seeing.
Indeed, time travel, and travelling faster than the speed of light, are intimately related in the Special Theory of Relativity. Looking at the situation from the other side, if it were possible to travel faster than light, then from some point of view, you would be travelling backwards in time. For more details, read about the definition of "simultaneity" in the Special Theory of Relativity.Probably none of the two is possible - travelling backwards in time, and travelling faster than light.Indeed, time travel, and travelling faster than the speed of light, are intimately related in the Special Theory of Relativity.

Travelling Like the Light was created on 2009-07-13.
it is not capable to produce light but it is capable by reflecting light
Probably, the word was light year, and this distance is that travelled by light in one year. Of convenient use in distant astronomy.From the most distant stars, we are just now seeing the light that has been travelling for 4 billion years or so.
The cast of Travelling Light - 1992 includes: David Bowie as himself
a wave model of light.
Depends on your average speed. Distance = Speed*Time. If travelling at the speed of light, 1.08 billion kilometres. If at the speed of a garden snail, 0.05 kilometers.
The sun is capable of producing its own light.
its a light behaviour that represents light travelling as a wave

Travelling Light - 1961 is rated/received certificates of: Finland:K-16 Finland:(Banned) (1964) UK:A
Travelling faster than the speed of light is not possible, therefore no galaxies have travelled or are travelling faster than the speed of light.
one billion light years = 5.87849981 × 1021 miles
