/sci/ - Science & Math

Hey /sci/ question came in my head that started bothering me.
So an object moving at relativistic speeds experiences time slower than everything else.
Does this mean it effectively takes longer to go somewhere near the speed of light?
Like I walk to my mailbox and back and it takes a minute. But I warp drive to my mailbox and come back and 60 years have passed and the bank foreclosed on my house. Does this mean we shouldn't even be trying to reach these speeds? Its basically just an incredibly inefficient time capsule.
