Nebular Hypothesis

I do not know anything about the nebular hypothesis. We are watching a movie about it to learn what it is what what it means.

How do you spot a meteorite?
        - Some leave craters
        - There is metal in them -- that is how you can tell them from Earth's rocks
        - If you use a metal detector, it is much easier to find a meteorite.

The largest meteorite weighs about 60,000 tons and landed in Africa

Iron 60 is only created in a super nova
    - Scientists are looking for meteorites that have Iron 60

Some scientists think that the super nova was what created our solar system:
     - We started out as a cloud of gas
     - When the super nova hit the could it collapsed and condensed, this created our sun
     - It made stars then gravity pushed all gas and dust particles together
     - This eventually created our solar system
NOT a fully accepted hypothesis but it is quite possible.
