I prefer the literal meaning, which is far truer than the one I replied to initially. You can't make something out of nothing (in a strictly physical sense), so nothing really is eternal.
Of course, you can (or I can using those wonderful things called Womens' Logic Plus a Rather Dusty Physics Degree) argue the opposite as well. WIth conservation of energy / momentum etc, and all that good stuff Einstein thought about, everything lasts forever, either as matter or energy, or some combination. You started off in a star somewhere.
