A State of Flux

Marcelo Gleiser, from "The Mystery We Are," On Being, November 9, 2012: 

The way we understand the world is very much based on what we can see of the world. Science is based on measurements and observations. And the notion that we can actually come up and have a theory that explains everything assumes that we can know everything — that we can go out and measure everything there is to measure about nature and come up with this beautiful Theory of Everything. And since we cannot measure all there is to measure, since our tools have limitations, we are definitely limited in how much we can know of the world.

So you can even build a theory that would explain everything that we know now. But then two weeks from now, someone else will come and find something new that does not fit in your theory. And that's not a Theory of Everything anymore because it doesn't include everything that can be included.

When you look out into nature, everything is in transformation at all times. And we see this at the very small and we see this at the very large [scale]. When we look at the whole universe, it is expanding, it's growing, it's changing in time. And so I look at things much more as a state of flux, of becoming, of transformation, as something that has some static truth behind it. So the notion that we as humans could come up with a final answer to the mystery of nature it's pushing things a little too far for our capabilities.
