Hi :-)

True that I don't know what I'm talking about when it comes to things that aren't heat-expansion related in terms of expansion. I'm only talking from my own practical experience, as that's the only thing that I know is true. Most of the ideas that are in current science courses are based on theory. Theory in my definition of the word is unverified ideas. I don't understand how scientists have arrived at the fact that the universe is expanding if not simply from theory. And theory is guessing. I'd rather not accept guessings.

If you're going to look at new ways of doing things, you can't think in a mode of thought common to the old. It requires a complete, quick, snap turnaround. You can't keep the old if you want the new.

Julian.
