The speed of light - about 670,616,629.4 miles per hour - is the ultimate speed limit of the universe, according to Einstein's theories and the vast quantity of supporting evidence and observation. As a result, this makes all but our most immediate cosmic neighborhood even remotely accessible. As a frame of reference, it takes light 4 years to reach the nearest star (other than the sun), and at the fastest speed currently attained by a manned vehicle, the journey would take about 110,000 years.
But maybe the ultimate speed limit can be "broken." Enjoy this article.
