Quote - So basically you are saying that the study of Astronomy is like history: the study of things past. Only with astronomy we have no idea what the current situation is because of the vast distance and time required (thousands, millions, billions of years) for light and sound to travel to our mini planet?

More or less.

Even the light from our own sun is @8.5 minutes old when we get it.
