Just to add to this, it depends on your reference (relativistic time dilation). For the people actually traveling at the speed of light it will seem significantly shorter. They could theoretically travel to the edge of the universe in 100 years, but to everyone on earth it would seem to take them the full 93 billion (not factoring in the expansion)
