serious question about the world

That is true no rocket leaves the launching pad at 25,000 mph but it does accelerate as it is moving away from the earth. As the atmosphere deminishes and the vacuum of space is reached there is no air resistance then you just need sufficient speed and acceleration to escape gravity. For example the space shuttle when positioned strategically around the earth and circumnavigating it can travel around the entire earth in 90 minutes. Id say that is damn fast probably up there around 18,000 mph or faster. Keep in mind that shuttle is still being held a set distance from the earth in an orbit. In other words gravity still has minimal hold. Food for thought. I’m in awe of the miracles and mysteries of space and astronomy.
