Travelling at the speed of light?[Question]

[Aoi Magi]

There are far worse barriers than asteroids while traveling at lightspeed, the first being the energy requirements. The space is too vast and the asteroids are not as closely packed as hollywood would have us believe, so charting a path while avoiding them is not that hard at all.

However even if we can gain lightspeed travel, it would still take us a few thousand years to get to the nearest star systems, not too promising when you think about it. This is where traveling through wormholes seem like a more lucrative idea.
