![]() But any spot (star) on the balloon can not catch up to the ant let alone the over taking in whatever direction the ant moves. If you consider two distant spots on the balloon, the distance between them can increase at a faster rate than the speed of ant on the balloon. That means that galaxies that are about 1 megaparsec (1 parsec 3 lightyears and change) away are presently getting farther away at the rate of 70 km every second, on average. Bezeugen Silhouette Im universe expanding faster than light Mehrdeutigkeit Henne Bestuben How can space travel faster than the speed of light How can space. Right now it’s about 70 kilometers per second per megaparsec. The balloon being universe and the ant being light. First, the universe doesn’t expand at a particular speed, it expands at a speed per distance. Lets start by saying the Universe is big. To understand it, consider a big inflating balloon on which an ant is crawling. Same way, there is no point of taking over as the space is expanding in reverse direction as well. ![]() And the expansion rate would be slow between light and nearby star. If the light is moving in the same direction in the neighborhood of a star, it is going to pass the star because, the expansion is not in only that direction alone. It is expanding in every direction and that is how it accumulates over distance. Moreover, there is no one direction of expansion of space. The expansion to exceed speed of light has to accumulate over very large distance. ( 12 votes) Upvote Downvote Flag Show more. But it does rotate, with a period of around 30 days (depending on whether youre closer to the equator or the poles, of course). The expansion of space accumulates over distance. The Sun doesnt rotate as a rigid object, since it is a plasma rather than a solid its rotation is somewhat faster at its equator than at its poles.
