  • Is Dark Energy the opposing force to gravity, or to Dark Matter?

    Your answer: 
    Nature seems to always be a balamce of two opposing forces at some scale. I once heard that dark energy is the force causing the expansion of the universe, while dark matter was the stuff that had slowed it down, before there was an inbalance (for lack of a better term). However, this documentary was saying that dark matter is not necessarily the... show more

  • Physics Question !?!?

    Your answer: 
    Suppose our Sun eventually collapses into a white dwarf, in the process losing about two thirds of its mass and winding up with a radius 3.0 percent of its existing radius. What would its new rotation rate be? (Take the Sun's current period to be about 30 days.) What would be its final KE in terms of its initial KE of today?
