Site Meter Ogre's Politics & Views: uniformitarianism

According to Wikipedia:

Uniformitarianism is one of the most basic principles of modern geology, the observation that fundamentally the same geological processes that operate today also operated in the distant past

This is the basis of much of today's physical science. It is presented in most basic geology and physical science classes, often as one of the first laws of science. In my experience, there is little discussion about this word.

However, even the basic definition given above is flawed. It claims that uniformitarianism is "observation" -- but then it applies that observation to the distant past. That's not possible.

Uniformitarianism says that everything you see happening today has always happened. In other words, it say that the rate at which water flows downhill is constant and has never changed. It presumes all physical laws, such as the speed of light, are what they are and have never been different. It presumes that gravity has always been at the exact rate it is today.

Now this rule certainly seems simple. In your lifetime, I'm sure that you can observe the same physical rules happening over and over again. You can observe the sedimentation rate of sediment in a stream. You can easily make predictions of ocean currents, rates of erosion, and many other related observations.

This is what modern science has done -- made observations and tested them to see if they hold true. They have found many laws that apply to various physical characteristics that always hold true -- as long as they are tested. The same experiments always give the same results because the rules do not change.

To me, I see this as rather self-centered. Just because physical rules have not changed in your lifetime, or even in the last hundred or two hundred years of observation does not mean they have never been different. Consider for a moment, what if this rule isn't true?

What if all the currently discovered laws of physics haven't always been true? What if, at some time thousands of years ago, gravity was different? What if the laws of thermodynamics have only applied for two thousand years? What if gravity didn't exist 5,000 years ago?

ALL of today's science is based on a complete and total belief in uniformitarianism. If uniformitarianism isn't completely, 100% true, a large portion of "known" science might not be true, too. Just consider it -- what are the possibilities if man simply cannot know everything?

Now there's no direct evidence that refutes uniformitarianism -- just as there is no direct evidence that uniformitarianism is true. It's just presented and accepted as fact, without debate. But what if it's wrong?

There actually now are some scientists that claim that this may be the case. They describe that the speed of light -- the basis of much of physics -- might not actually be constant. What if all the physical processes we see today were actually different at some time in the past?
