Vedclass · Answer

(D) The statement “the universe is expanding” refers to the observation that the space between galaxies is stretching over time. It does not mean the universe is expanding into a pre-existing space,nor does it imply an infinite universe becoming 'more infinite'. Therefore,the correct interpretation is that the metric of space itself is expanding,causing galaxies to move away from each other. Since none of the provided options $A, B,$ or $C$ accurately describe this physical phenomenon,the correct choice is $D$.
