Are You Really Sure?

What if the speed of light isn’t constant? You don’t have to think too far into that question to surmise that it would break a lot of what we think we know about the universe.

VSL (Varying Speed of Light) is a real theory that has some traction, but is considered out of mainstream physics. It does resolve a few very sticky problems in our current understanding of the universe. For just one example you probably aren’t aware of…the cosmological expansion we often hear about actually appears to be accelerating, which in current (constant speed) thinking would imply that on a large scale gravity is repulsive. The science we accept is not at all iron clad.

There are two ways to look at this:

  1. What can we be sure of? The answer, truthfully, is not much. Everything can be questioned.
  2. When the prevailing science gives us a solid answer that remains stable for decades, we can be sure enough that it’s true to go ahead and act on it. That’s being practical.

There is always going to be that shred of doubt. It’s usually nothing, but sometimes a universe can be found there.

Okay, it’s mildly interesting to entertain these thoughts, but really, what difference does it make? It doesn’t impact that I have to go to work tomorrow, or take out the trash. Does it? Well…first, you don’t really have to do any of those things. Second…it gets to the religious question, and that changes potentially everything about what we’re supposed to be doing.

The more you learn about these subjects, the more you discover that “we” (as in the human race) know a lot more than “we” (the individuals) are aware of. We really do know and understand a lot about how the universe works. At the same time, you begin to see how many problems and mysteries there are within and around all of these things we think we know, which makes the mysteries all the more profound and troublesome.

As I have written before, it takes a bit of a leap of faith either way.

The more fundamental (to me) question is…what makes us leap one way or the other? Why do some look up at the sky and see God, whereas others look up and see only physics? Really think about that question for a while. What tips the scale one way or the other for an individual?
