If the universe as a whole is moving at great speeds and spaces is a mostly vacant vacuum why aren't space shuttles lost when they brake free of gravity?
Is it?If the universe as a whole is moving at great speeds
OKand spaces is a mostly vacant vacuum
Space shuttles don't escape earth orbit. (And they are part of the universe, just like everything else.)why aren't space shuttles lost when they brake free of gravity?
Because the object is already moving at the same speed as the solar system. I takes a force to change the velocity of the object, and there is no vacuum Universe Wind force to blow the object away. It's the same as if you are standing in the trailer of an 18-wheeler going a constant speed down the highway. You toss a ball up and catch it, just like you were standing stationary in the park.Um, yes, sorry. What I'm laboring to ask, is what keeps a free object in space from getting left behind by the moving universe?
