Interstellar Expansion WITHOUT Faster Than Light Travel

Season 10 Episode 9 | 20m 15s

In the far future we may have advanced propulsion technologies, but what if those technologies never materialize? Are we imprisoned by the vastness of space—doomed to remain in the solar system of our origin? Perhaps not. A possible path to a contemporary cosmic dream may just be to build a ship which can support human life for several generations; a so-called generation ship.

Extras
We only recently figured out where cosmic rays are coming from.
Black hole complementarity may force us to rethink what it means to say that it exists.
Today we are jumping into a black hole. Again.
The Moon: humanity’s first destination beyond our atmosphere.
So how did humans figure out the solar system? Eclipses!
Is gravity just an emergent effect of entropy?
Is our 3-D universe is just the inward projection of an infinitely distant boundary?
What if aliens are deliberately keeping quiet for fear that they might be destroyed?
So what exactly is an EMP, and how dangerous are they?
The terrible singularity at the heart of the black hole may be no more.
