Let me just post something for those who haven't yet studied special relativity.



This is a time dilation graph, but its the same curvature for mass dilation as well. As you approach the speed of light, the mass of the object becomes unfeasibly large. At one point, it would be so large that, if you applied all of the energy in our galaxy as a force, the speed increase would be infinitely small - it still wouldn't hit the speed of light.



The equation for mass dilation. The math doesn't lie - based on current scientific knowledge reaching the speed of light is impossible; it's a universal constant. However, as Souleater said, I won't say it's impossible. That's what makes science so brilliant: it is continually evolving as scientists continue to research and build on existing ideas.
