He video shows a collapsing cloud of interstellar gas, which is held together by the mutual gravitational attraction of all the atoms and molecules that make up the cloud. as the cloud collapses, the overall force of gravity draws the cloud inward because 1) gradually becomes stronger(blank 1) gradually becomes weaker(blank 1) stays constant at all times(blank 2) the strength of gravity follows an inverse square law with distance(blank 2) the mass of the cloud increases as it collapses(blank 2) the total gravitational force is a conserved quantity
