Cryogenics / worm holes are still a possibility!

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.

Cryonics.
Cryogenics is an extant art/science.

True, and maybe the galaxy will be settled by Tardigrades.

Extant, but not in a way that doesn’t destroy cells and thus the body during the process of freezing.

You misunderstand me (or I wasn't clear).

Cryogenics is the engineering of low temperatures. I've worked in departments that specialized in cryogenics (we tested foam thermal conductivity at low temperatures for clients).

Here

Cryonics, a different word, is the study of how to cool biota, the cellular preservation mechanisms, and so on.

Oh sorry, you are right! I totally misunderstood.

in high school I read something about bending atoms near the ship to create a warp tunnel or something. I think we're only just starting to explore that idea 20 years later with dark matter.
