The variation in oblateness of all celestial objects & universe is according to this video. This variation in oblateness is in very ideal form and is 100% variation but actually for different calestial objects oblateness variation value is different. From black holes, galaxies, stars, planets, their moons the value of variation in oblateness decrease. Also the meaning of variable oblateness that scientists have been studying in some stars, the sun, planets & the earth is only variation in polar & equatorial radius. But the meaning of variable oblateness according to my ideas is different. According to me all celestial objects & universe oscillate between two different confocal oblate spheroids. In all celestial objects & universe dark matter & dark energy have the structure of confocal oblate spheroids. So all celestial objects & universe contract & expand according to this oscillatory geometries. In this oscillation I also show variation in polar & equatorial radiation but I have a new method of variation in oblateness that is different and new. I also say about variation in oblateness and variation in polar and equatorial radius but I am adding or including two new and different condition with this variation. What I am including is to first include confocal property of a oblate spheroid and second twisting and squeezing a confocal oblate spheroids. Twisting in reverse directions in both hemispheres and squeezing on poles. So there will be variation in polar & equatorial <b>...</b>
