It was the Greek philosopher Heraclitus, not the Bible, that said “Change is the only constant in life.” He said that in the time of Isaiah! That was 500 years before Jesus, when, in my mind, things didn’t change that much. We quote Heraclitus nowadays because so much changes. And in a post-Einstein world, we kind of think that everything changes, even our understanding of the truth, that everything is relative. And that everything changes. There are no constants that we can count on.
But even Einstein believed in constants. Remember that famous equation E=mC2? The C of that equation stands for Constant. Light, as far as Einstein was concerned, is constant. The Bible nods its head at that idea too.
Physics suggests that there are several constants. Look up Planck’s Constant – it’s fascinating. And incredibly precise. The constant speed of light is likewise precisely measured: 186,000 miles per second to be exact.
The pull of gravity is also understood to be constant, but that figure has been elusive. A physicist at the National Institute of Standards and Technology in Gaithersburg, Maryland by the name of Stephan Schlamminger has spent the last 10 years trying to ascertain that number, and the number he has come up with is different from everybody else’s ideas. Even the experiment that he was trying to replicate. Bless his heart. He called his endeavor “life-sucking.” You’ve got to feel sorry for a guy that spends 10 years of his life on an experiment that essentially failed.
If something is constant, how in the world can you not measure it? I’m sure Dr. Schlamminger has asked himself the same question for the last 10 years. I don’t have the answer to that; he suggests that gravity is the weakest of the four fundamental forces, and… yeah, it got a little foggy for me after that.
I don’t think, as he does, that just because you can’t measure it doesn’t mean that it doesn’t exist. Just because you can’t figure it out doesn’t mean it’s not true. Wait. Say that again…. Just because you can’t figure something out doesn’t mean that it’s not true. That is true for the tests and measures around gravity, but it’s true in the spiritual life as well. I will never understand how my mom lived as long as she did without food and water. Nor how her illness did not cause her pain. But her life during those months was real, and redemptive for me, and for many. Incredible, real things happened in those days.
The inability to figure things out does not equate to failure. Schlamminger described his testing as a long walk through a dark valley (which has echoes of Psalm 23). Life leads all of us through some “valley of the shadow of death.” Those valleys feel like failures, and very well may be, but they do not mean the end, or that God is not with us. Psalm 37:23-24 says: “The Lord makes firm the steps of the one who delights in him; though he falls, he shall not be cast headlong, for the Lord upholds his hand.”
I can give witness to that truth. Not all has gone well for me. My body has failed in rather catastrophic ways, for instance. And yet I can say that the Lord has made firm my steps, and though I have fallen, the Lord has been graceful to let me get up again, and again. A failed 10-year endeavor to come up with a number has to be tough, but not the end.
And one last word. My experience of, and my trust in, gravity is unaffected by Schlamminger’s testing. When I put my cup down on the table, it still stays there, even if we don’t know precisely the force that keeps it from floating away. The constant is not invalidated by the lack of measurement. God told Micah: I the Lord do not change (Micah 3:6). Even though Heraclitus’ dictum seems true, it ultimately is not. God is constant. God does not change. God will always be faithful. You can count on that (pun intended).
