Earths end close to Mars

Dirt from Mars proves that it once was a Planet with atmosphere and wasnt just a big desert. Also you may have heard they have found fossilized water cells in the soil. Will the earth see the same effects as mars in the future. Experts beileve that mars had a atmosphere that collapsed. The reason for this is a beleif that mars Core died and like earths core it has electrical waves and if the waves just disapear the Atmosphere collapses. What do you guys think about this theory? Can it happen to earth in the future?

sounds believable. i mean nothing can last forever, but thats the first i heard of Mars' atmosphere collapsing. i do know that the sun is growing a small amount every year or something like that. Maybe this could cause those electrical waves to stop functioning?

It's very possible. Though I can't see it happening for another million years.

I don't believe that Mars once had an atmosphere, though. I believe that there are traces of atmosphere around the planet, and that's why they found traces of water. Maybe the atmosphere around Mars (what's left of it) is in motion.

Or maybe I am wrong, and there was an "end" to Mars. I still stick with my theory that there are traces of atmosphere left, and that's how the water was formed, also, the atmosphere is in motion.

That's fine but:

1) It still has an atmosphere
2) fossilised water 'cells', water is made from molecules.? ???!
(It had and most likely still does have water, is that what you mean?)

However if the magentic field surrounding our planet relies on the core, then yes Mars may have had one in the past and the collapse led to radiation bathing the planet and exterminating all life and evaporating the water, etc.

What i heard was they were water molecules that were fossilized... I didnt know there was actually water on mars.

I don't believe we have anything, currently on Mars, cabable of detecting any form of fossils, there are a few visible anomolies in the raw data from Spirit and Oppurtunity which look a little like fossil shells, but we can't analyse them to determine their exact origin. I'm not sure a molecule can be fossilised, and if it was possible somehow it would be far too small for any current equipment on mars to detect, as you are talking about an incredibly small cluster of 2 elements.

However by analysing the geology of the areas in which the rovers landed (which was their primary objective), they have determined that mars was at least once covered in areas by a briny sea. Some evidence, I believe, suggests that it may still have water, and I know that one of the objectives of the Radar array on the ESA craft is to try and find any underground pockets of water. I'm not sure what the latest is on all of this as I havn't been keeping up to date to be honest.

I thought the reason Mars doesn't have much of an atmosphere is that it's much smaller than Earth and couldn't hold onto it with the lower gravity level.

Also, when they talk of fossilized water, I think they just mean pockets of ice underground that has remained there frozen for eons.

when the sun burns out we all die!!!

f this ... im goin' skydiving !!!

What happened to the atmosphere at mars might be the samet hing that is happening to our own atmopshere. We all know that the earth has two magnetic poles, North and South. Well about once every few thousand years, they switch and do a flip. With the poles in their current position their create a barrier from radiation from the sun so we don't get skin cancer and other wonderful ailments from the sun.
This barrier also helps protect the atmopshere from the same radiation and this radiation can destroy the atmopshere if it weren't for the sheild from the poles. So when the poles flip, the atmopshere will be left without a defense for a few years. The switch can take from 5 to 25 years to be completed, and in this time we will have not much protection for our atmopshere and could be destroyed pretty easily. This same thing could have occured on Mars.
From recent scientific research it seems that a flip of the poles on earth might happen soon, perhaps in the next 50 years or even less.

More than likely the explosion and birth of the sun may have cause all the ice to melt, forming a thicker atmosphere, and then subsided and water frozen as the sun weakend.
