If the result changes, then we are not speaking of rederivation anymore. You can rederive the same results as many times as you want: The rederivation never becomes the original derivation.

But at least "part" is among the most common words. So, you probably would have to go for "smallest parts that all things are made of" or something like this.

That was really nice. So probably you study epigenetics?

I do get the overall meaning, but I am still wondering what you are referring to by "sky bag air".

I was just wondering about the simplest way to describe the existing observations. And if the density per unit volume stays constant, although space continuously expands, then it seems to me that the simplest description might actually be to treat it as an intrinsic property of space.

So, the tendency to expand can be considered an intrinsic property of space, as long as there are no other interference factors that compensate this tendency to expand?

That's true. But you cannot change the original derivation of something at a later point in time. If a result was originally derived in a certain way, that will will stay the way it was originally derived until the end of time. It might turn out that there are additional ways to derive the same...

@HunterThomson: So did the amount of dark energy increase?

This is what I always thought, but then I saw a feature with a German astrophysicist where he argued that in the big bang, not only space but rather space time expanded. The statement appeared a bit strange to me, because expansion clearly seems to be a temporal process. You compare some...

Hello everybody, When we say that the universe expands, what exactly do we refer to: Space or space time? Is it only a spatial expansion or also a temporal expansion? If it is also a temporal expansion , what are the implications w.r.t. to inflation and accelerating expansion?Robert

And how does Star Wars fit in here?

Is naturalness anything else than a pure aesthetic argument? Why should we expect nature to be elegant?

As a reader I do take it seriously, because I am one of those who do not like fantasy at all--at least not when it comes to reading. I can watch something like Star Wars as a movie, but I would not be able to finish a book written in the same style. Thus, SF/fantasy is a warning for me not to...

Yes, but then Star Wars ends at SF/Fantasy which is exactly where it belongs.

Space Opera and Steampunk are clearly cross-over genres and *not* pure SF subgenres.
