As was already pointed out, a brown dwarf is a small star about 13 or more times the mass of Jupiter. A white dwarf is a collapsed object with very dense matter - they would not have been able to hoist a piece with a crane. They made the statement that the Moon used to have 1/6 the mass of the Earth - no! It was (is) 1/81 of the Earth's mass, or 0.0123 -- they mixed this up with the gravity being 1/6 that of the Earth. So on the Moon you would weigh 1/6 of what you weigh here.
A piece of this degenerate matter would either go right through the Moon or the Earth or sink to the center of either body.
The meteor shower is shown to stream in parallel lines in space to the Earth. Usually the meteors would actually seem to originate from a point in space, the radiant. This is like driving through a snow storm. But, to be fair, if the meteors are really coming from a nearby area, they might follow the paths shown.
If the Moon was now twice the mass of the Earth then the Earth would be orbiting the Moon. There is a complex interaction of the Earth, Moon, and Sun and the spin axis, the length of the day, etc. will all be changing.
Then they are shocked to see there may be a collision. You either have a stable orbit, or get flung away, or you crash. That's life with gravity.
Another issue is the constant scenes of the Moon with a bunch of debris hovering around it - either the junk is orbiting or it will fall back down to the surface. The same side of the Moon may not keep facing the Earth - the impact might set it spinning, or the oval orbit could break up the 1:1 resonance with the Earth.
The scenes of things floating up are odd. The gravity of the Moon could balance the Earth's gravity if it had the new mass and was closer. But they attribute this to some electric - magnetic effect. I could not understand the explanation - yes, we are all made of the same stuff, but obviously not everything is affected much by magnets. A white dwarf can have extreme magnetic fields, but you probably would die if it could lift you. Your bodily functions and cell growth would be messed up. The heart beat would be messed up, too.
