If space were curved and gravity acted on objects like so then faster objects affected the same by gravity as slower objects...right?
Like two baseballs of equal mass are thrown but one travels at a faster velocity the one with the +in velocity will not fall as fast.. Why is this, is this true in a vaccum with no friction? I mean if gravity works because large masses curve space then shouldn't speed be irrelevant?
Im not very familiar to M-phase so please do not mention it or string theory or parallel dimensions.

Gravity's effect on faster objects is not smaller. Two baseballs thrown horizontally will both hit the ground at the same exact moment, regardless of their different initial horizontal speeds. The faster ball will cover more territory before impacting than the slower one, but after one second they both will have fallen the same distance vertically. You are thinking that the faster ball will fall less far when traversing a fixed horizontal distance, such as say, 20 feet, compared to the slower ball also traversing 20 feet. But this difference is entirely due to the difference in time involved, and nothing more. I hope this helps.

Your question has nothing to do with curved spaces or the difficult string theory and the answer is quite simple; the two baseballs of equal mass are attracted with the very same force by the Earth; it just happens that the faster travels a longer path (well, because it is the faster!) and falls beyond the slower.
If my English is not OK, feel free to correct it. Thank you.

I'm not quite sure what you mean when you say that gravity's effect on faster objects is less. The two baseballs will fall at the same rate. Of course, if the fast one goes fast enough, it will just 'fall' around the earth. This is called an orbit.

One word: Inertia. It takes more force to change the trejectory of a fast moving object than it would a 'slow' moving objeect.
