Sam arrived in a sharply tailored uniform which said two things immediately to anyone who looked at her: she had her proverbial shit together and she was hot. She strode across the floor with complete confidence and shook the hand of the professor before she stepped to the lectern.

"Hello, I'm Major Samantha Carter, but don't let the rank fool you. I also hold dual doctorates in theoretical astrophysics and engineering, I'm a fully trained soldier, pilot and completed space mission training before taking another line of work for the Air Force." She paused for a moment to let that sink in and kill some of the usual questions and concerns of her gender right off the bat.

"I'd like to thank Professor Colan for inviting me here to speak today and hope this will be an enlightening hour for all of us." Sam again gave a moment for the room to settle before she began.

She sat in on a lively discussion of string theory which easily tied into general relativity and then led to her farther afield topic and the one that the professor had really invited her for. "And that leads to M Theory. Or what you might know better as Multiverse theory. This is not as crazy and out there as you might think or have heard. And it's become more and more mathematically obvious that there is validity to the theory. Other timelines, infinite varieties of them, branching off from our own and running concurrently with changes as tiny as a single atom to ones where life never started on Earth."

That was a lot for college kids to take in so she helped herself to a sip of water before she went on.
