[Talk] "Time Travel" (YAMAMOTO)

This week's topic is "Time travel".
The movies and novels of time travel attract us.
If you can see an undesirable future, what will you do to prevent it?
If you can change it, is it the future or just one of a number of possible futures?
If you go back to the past and change it, what happens to the present?
Let's talk about "Time travel" freely.
