(22,048 posts)Dr. Krauss makes a crack later in the lecture that hes running out of time because the introductions went so long!
The lecture itself is informative and entertaining.

(22,048 posts)Basically, theres no such thing as nothing. Empty space is full of the virtual particles that pop into and out of existence so quickly that they cannot be observed or measured. But their existence can be sensed by other means. These particles create energy. So, empty space isnt empty!
What a universe we live in!

And those virtual particles created the big bang I think...
