How fast do you need to go to get to a new galaxy?

To reach a new galaxy, such as the Andromeda Galaxy, which is about 2.537 million light-years away, you would need to travel at a significant fraction of the speed of light. Currently, the fastest human-made object, the Parker Solar Probe, travels at about 430,000 miles per hour, which is only a tiny fraction of the speed of light. Even at that speed, it would take over 6,000 years to reach just the nearest galaxy. Thus, with our current technology, intergalactic travel remains beyond our reach.
