Light speed is very hard to imagine but our current mathematics suggest that we can achieve 99.99% of speed of light. Ever imagined what happens when we actually perceive it in reality? Watch the documentary below explaining what will happen when we reach the ‘Light Barrier’.
This video looks at the current spacecraft speed records with Apollo 10 holding the record for the fastest manned spacecraft, New Horizons probe for the fastest Earth escape velocity and the Helios probes for the fastest heliocentric velocity. But Solar Probe Plus will beat that when it launches in 2018. While Voyager 1 doesn't set any speed records, it was the first spacecraft to leave the solar system, so therefore the fastest solar system escape velocity by default.
