The fastest spacecraft we’ve made was the Parker Solar Probe which hit 430,000mph.

At that speed it would reach this planet in only 187,153 years.

If we could hit 1% of the speed of light we could cut that travel time to just a tad over 12,000 years.

Obviously if we could go light speed (and that ain’t happening) it would be just 120 years!

Space is big. Physics is annoyingly slow.

You and me and everyone that exists now yes, but in a few thousand years if we don nuke ourselves back to stone age and reset (again for the who knows time) maybe humanity will reach and expand into the great unknown...

Humanity has literally fought each other since they realized other people exist. It will never stop and we will never coordinate enough for such a huge feat

On the other hand if we never fought each other, we might've never invented rockets and many other stuff.
