You explained how 3 of the basic forces are reduced to one force near the beginning of the big bang. Gravity being the outlier. But didn't Einstein say that gravity is not a force; it is just a result of the geometry of mass deforming space/time? Why do physicists consider it a force?
Back to the baseball. I’m on a space walk traveling at 28,000 iPhone and throw a ball at right angles to my path at 100 mph. The thing is, the ball still is traveling at 28,000 kps in the direction I am going plus 100 kps at right angles. So, to your point, it will still have an orbit that any other body traveling at 28,000 kps,only with a different apogee and perigee. I know I haven’t stated it exactly right, but do I have the gist of it? Also, what is the name of that game or what is the link?
