the past? That eyesight, and other sensory apparatus, is to slow to capture real time.

well I suppose that it is technically true. WHen you see something happening, it's happening in the past.. maybe a few nano seconds. It takes time for light to be reflected from the object you are observing and back to your eye. So during that time the event which you think you are observing has actually already passed. Of course we are normally talking about such small times that they would be hard to even measure. The effect is most obvious when we look at things that are very far away. If we use a telescope to look at a star that is millions of light years away, that star may not even be there anymore. We are lookling into the past in a sense. The light reaching our eyes from such stars took a million years to reach us. So we are seeing how the star looked one million years ago.

No. I can catch a baseball when it's thrown to me or a frisbee that may take a wild path and that requires real time tracking.

It does take a little time for light from a passing automoble to reach my eyes, but - at 186,000 miles/second - its very, very, very little time.
