Modern thinking is that time did not start with the big bang, and that there was a multiverse even before the big bang. In the inflation theory, and in string theory, there were universes before our big bang, and that big bangs are happening all the time. Universes are formed when bubbles collide or fission into smaller bubles.

Language and emotions are too easily misread. For example, laughing can mean many things: laughing with you or at you. Does that laugh reflect joy, anger, or that s/he's about to fire you? Too many jobs require complex feelings, pattern recognition, common sense, and the human touch.

Science is about principles. It's about concepts. It's not about memorizing the parts of a flower. It helps to know some of these things, but if that's all you do that's not science, science is about principles and concepts.

For most of human history, we could only watch, like bystanders, the beautiful dance of Nature. But today, we are on the cusp of an epoch-making transition, from being passive observers of Nature to being active choreographers of Nature. The Age of Discovery in science is coming to a close, opening up an Age of Mastery.

This is a huge step toward unraveling Genesis Chapter 1, Verse 1-what happened in the beginning. This is a Genesis machine. It'll help to recreate the most glorious event in the history of the universe.

The energy necessary to create a wormhole or to wrap time into nuts is incredible. It's not for us. It's maybe for our descendants who have mastered the energy of this technology. So if one day, somebody knocks on your door and claims to be your great great great great granddaughter, don't slam the door.

The next big accelerator might be the ILC in Japan, a linear collider which might be able to probe the boundaries of string theory. So we physicists have to learn how to engage the public so that taxpayers money is used to explore the nature of the universe.
