What is astonishing is how little these space crafts have travelled. They go at 38k mph and it would have still taken them 40,000 years to reach nearest star to the earth! The fastest space craft so far is Parker Solar Probe which was about 10X faster but even that would have taken 4000 years to get to nearest star. There are huge problems increasing speed beyond this because even a tiny particle can seriously damage the space craft at higher speed. The expanse of space is truly mind blowing. If physical requires that for a body to move from point X to Y it must travel through all points in-between then we are screwed.
