Re: Too early to tell.

"It's not about assumptions, it's about theories. And it's always time to re-evaluate theories in the light of new information; we call this process "science"."

Strictly speaking it's about hypotheses, not theories; and just because new information may cause us to expand an existing theory it doesn't stop us continuing to use the old theory as long as its predictions are still useful.

Einstein's General Relativity may have superseded Newton, but Newton's theories are still good enough for NASA successfully to compute the orbits for the Voyager missions for example, and when something replaces General Relativty, our GPS systems will continue to work in spite of that.
