> Hi list,

>

> I know I've posted a lot today, but bear with me. I've been doing some 

> research since I found the article on the meteorite that Mars rover 

> Opportunity found on Mars earlier and it got me to thinking about how it 

> got there and where it was from. This led to more research and more 

> questions...

>

> We know meteorites come from other celestial bodies, whether they be from 

> asteroids, comets, or planets. All types of meteorites have been found on 

> Earth but... What about the reverse?

>

> We know it happens because we have lunar and martian meteorites here on 

> Earth. Over the last few months I've been reading about panspermia and 

> artificial planet seeding too which are very interesting topics.

>

> You can imagine the force a huge asteroid would exert on the crust of our 

> planet during an impact event and would eject quite a bit of material into 

> space.

>

> This all brings up some very interesting questions... If Panspermia is a 

> theory, then wouldn't reverse panspermia (life originating from Earth) 

> suggest it's very plausible and not just possible to seed life on other 

> planets from another by impact, travel and time?

>

> Having said that let me illustrate a scenario. A huge asteroid impacted 

> Earth millions of years ago throwing millions of tons of debris into our 

> atmosphere. Some of this debris will escape Earth's gravity and make it 

> into space. How much is arguable. Wouldn't it be possible for some microbe 

> or bacteria to be preserved deep inside a clump of Earth, and flash frozen 

> in the iciness of space?

>

> How many billions of bacteria, and microbes, or even insects have been 

> launched into space over the hundreds or even thousands of large impacts 

> the Earth has been subject to since the beginning of time? Look at the 

> jungles of South America and Africa and other tropical regions. The 

> density of life in any given square foot is higher than on any other place 

> on the planet. If a large Asteroid impacted this region you can imagine 

> the sheer numbers of "life forms" that escaped Earth.

>

> Survivability is the issue. If the microbe or "life form" is deep enough 

> within the stone, rock, or clump of earth, wouldn't it be preserved. 

> wouldn't this Earth rock act as a capsule to transport life outside our 

> own solar system? Current science tells us that the temperature of the 

> interior of a meteoroid entering our atmosphere is relatively low. In fact 

> it is usually ambient to space. In other words cold! Frozen even. This is 

> sufficient to allow a microbial life form to survive isn't it? Look up 

> Water Bear on Google...

> Wouldn't this mean that there could be space rocks out there with "life"

> there that comes from Earth, it wouldn't take a rocket scientist to guess 

> that there might be other material out there that might just have come 

> from another habitable solar system. I know these are big jumps and 

> guesses, but isn't it possible considering the sheer length of time, the 

> age of our planet, and the number of impact events over this time period 

> on other celestial bodies and planets?

>

> I mean we are talking about billions of years here...

> Your thoughts?
