Well, really, speculation about that has been going on for years...
In my opinion, I don't see the distance between the sun and the planets having evolved that much over the four billions years+ that they're
On the other hand, while at the same place, the conditions of Mars (of all the rest also in fact) could well have been very different, and the sun
itself was slightly different (though I think it must have been then slightly cooler). Earth, 3-4 billions of years ago, was not at all the same as
now, and even just a few dozens of millions, which is, compared to planet ages, very small. Thus, Mars, just a few millions of years ago was probably
very different, and there are numerous stories, here on ATS and elsewhere, that tend to prove that water was freely flowing on a warm
today's-earth-like planet, some time ago (a few millions, a few hundred millions?...)
I believe that the fact that the universe is expanding is as such not perceivable (very, very small influence) in differences of distances within our
own solar system, even over millions of years, because we are a "closed" system, the central star keeps on attracting the objects around it. I
believe that this expansion occurs on a larger scale.
Any one maybe having more info on the estimated "rate of inflation" of the universe? I'm curious to know about it, though I think this must not be
significant at our scale.
