The Moon is Alive

Interior of the Moon

Okay so how 'alive' can any celestial body really be? I don't know how you would define an alive planet but
our Earth is certainly alive and one of the main reasons is because it still has an active core. The moon also still has an active core! The moon is not a cold chuck of rock floating around the earth. There is still an internal layer of the moon that generates heat due to gravitational forces.
How can scientists possibly know that?
Definitely....how can you really know anything?
Well since we can't really get a drill on the moon and put a thermometer into the core we can only use data we can measure and perceive. This means measuring the different deformations other gravitation fields have on a particular celestial body...the physics gets pretty intense pretty fast so suffice to say we can measure subtle changes in the shape of the moon as it rotates around the Earth.
This change scientists can measure is called a tide...the phenomenon on earth we generally refer to as oceanic tides. The gravitational forces between the sun and the moon are so powerful we can easy see the water displaced in our oceans.

As the moon deforms its inner layers transform some of that energy into heat. That heat maintains the soft layer within the moon. The softer the layer the easier it is for the moon to transfer energy into heat....see the cycle?
