Time & Space

"You're not moving.
Time and space have switched places here
- The event horizon
You can't move through space, and time is extended forever.
One second of your time is an eternity to me.
- Is the edge of the universe running away? No, that's not it, but something's expanding. What is? The universe? Me?
You mustn't look back. Eternity isn't infinity. Even if time appears to extend toward eternity, an end still exists.
- When will it be one second later?
Look forward. Reach forward. You mustn't turn back."
