    Those are the ideas I was referencing as taking decades tbh. Technically a few, especially the laser sail, can potentially get to high enough fractions of lightspeed to get that noticable time dilation effect, but given that makes something that already costs a huge amount of energy, much more expensive than it already is, I’m not sure if you’d actually want to go to those speeds very often.
