    It wouldn’t be the first time we discovered that some previously constant forces are actually variable (much the way the force of gravity is affected by distance, noticeable only when you lob something high enough.)

    More specifically to your example, we discovered that gravity isn’t a force at all- it’s a literal curvature of space-time caused by objects with mass, which is why its effects aren’t constant.
