Have we made an object that could travel 1% the speed of light?

The fastest things ever made by humans are spacecraft, and the fastest spacecraft reached 330,000 mph – only 0.05% the speed of light. But there are ways to go faster.

Warp drives: Physicists give chances of faster-than-light space travel a boost

If humanity wants to travel between stars, people are going to need to travel faster than light. New research suggests that it might be possible to build warp drives and beat the galactic speed limit.
