If you beleive in the big bang theory then you probly think the universe is expanding . so I Theorize that Earth was closer to the sun and mars was in the life zone and life flourished on mars and earth was like venus. until our planets slowly began to move outward and earth got in the life zone. but I think our sun will die out before venus ever gets in the life zone. Any speculations?

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 formed...

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.

The universe is expanding between galaxies, so the planets moving away from the Sun due to that is out of the question. The Earth does move away though, but only a slight bit per year. That's due to the solar wind pushing the Earth out slighly, the Sun losing mass each year, and tidal forces.

As for SpookyVince stating that 3-4 billion years ago wasn't that different from today, it really was in planetary terms. That's about 3 to 4 fifths of the Earth's entire existence.


Anyway, I really ca't say about past life on Mars. The real question is if there is any there now.

I'm happy to be able to answer your life on Mars now(?) question with a very positive YES ! There is life on Mars now and apparently has been life on Mars probably a similar time frame as life on Earth. Mars had dinosaurs ,from fossils I saw at Opportunity site 20 feet from the lander in the outcrop,Feb 2004. Op later micro-imagessome baby Mars dino fossils an egg and ovipositor in asame shot sol 15. There are people like us on Mars who look like us and wear clothes,and hats.

vze2xjjk, why do you constantly try to hijack threads with your outlandish and baseless theories that there are dinasours, people, and whatever living on mars and add in extremely pixilated, low resolution images to back up your claim? You're becoming an laughing stock, and it's getting really annoying. I've never used the ignore button, but I'm am sooooo tempted.

sigh
