Reply to comment by nyg8 in How would we get about traveling through deep space? by MysteryMystery305

Hypothetically, light speed might cause time dilation that makes the trip seem far shorter for the passengers than the people on earth.

While true, time still passes for the person inside the space ship, if we need to travel 80 light years, you will have to survive 80 years

The people outside your ship will need to live 80 years if they want to meet you again. You'll only need to live for 50 or so

The dilation is exponential. The closer you get to c, the higher the dilation factor. With enough energy, from the perspective of the travler you could practically travel anywhere instantly...so long as you didn't mind the rest of the universe moving along without you.
