 Molecule is, you know, the atomic clock that tells us when time is moving. But time is all relative. If you take that atomic clock and raise it a foot off the ground, it runs at a different rate because gravity, you know, it's so sensitive they can tell the difference between the atomic clock on the ground versus a foot above the ground or a meter above the ground because gravity is lighter there, right? So we know that time runs at a different rate depending on the gravity. So all these temporal models are hard to get our head around.
