Interstellar travel is a whole different matter. Schoolboy maths is sufficient to derive a proof that the speed of light is an absolute limit, starting from Einstein's initial postulate that it remains a constant to all observers regardless of their motion (that's called "Special Relativity", children.) Fancy schmancy wormholes aside, there are plenty of cheap, easy ways to get a spacecraft close to that limit - Bussard ramjets, light sails, take your pick. Ironically, it's getting the fuckers to slow down again at their destination that's the trickier bit.
Even Filipinos won't take that job, though, so I suspect it'll be up to Siri and Cortana to greet our new galactic overlords when they finally get there
