to the moon, alice. >> to the moon. i remember one small step for man.t leap for mankind. >> look at that. >> we're talking about the moon here tonight. and so this goes all the way back 40 years to landing on the moon. you know, 1969 in july. not only did man walk on the moon but they also took samps from the surface of the moon and brought them back to here in the u.s. they analyzed them and found out that the moon rocks had magnetic properties. they're like what? this has been baffling them all of this time because the moon doesn't have a magnetic field. the earth has a magnetic field. here's why. they i've got this avocado. it helps explain the structure of the earth. we have our solid inner core. the meat is the hot magma of the earth. wa we've got our outer crust. because the earth spins, that creates motions and creates a magnetic field. the moon is one big chunk, one big hunk of rock basically and it doesn't spin. it's too cold to have some of these properties so they're like, why is it then that there could be magnetic properties in these rocks.
