Consider: - I leave Earth and travel 1ly at speed c - I arrive one year later - An Earth telescope will see the destination as it was when I left - It will take another year to see me arrive So in a way that's already happening because I'm traveling quite quickly - twice as fast as it seems from Earth's perspective - and I arrive in what appears from Earth to be the past.
