Though I don't agree with why sans and Gaster may have done this, it is interesting to think that they were looking to create something to time travel with and manipulate the timeline.

Toby mentions that this is the best outcome - why would that be? sans isn't happy about it. He keeps the machine in his garage with the blueprints out because he may look at them from time to time. So, he time travelled to sometime before our timeline and the machine broke.

Perhaps the machine breaking is a commentary on integrity - sans and his brother both utilize this trait in their attacks. Without the ability to time travel to avoid consequences, morality and integrity may be washed away in favor of experimentation and science.

Maybe there are things that no man (or monster) should be able to do.

I don't know. I'm going to think about this theory a little. Thank you for your post! ^^
