Time Travel May Be Possible, But It

Gravity Is So Strong That Space Is Bent Round Onto Itself, Making It Rather Like The Surface Of The Earth. If One Keeps Traveling In A Certain Direction On The Surface Of The Earth, One Never Comes Up Against An Impassable Barrier Or Falls Over The Edge, But Eventually Comes Back To Where One Started.

Science Could Predict That The Universe Must Have Had A Beginning.

Bodies Like The Earth Are Not Made To Move On Curved Orbits By A Force Called Gravity; Instead, They Follow The Nearest Thing To A Straight Path In A Curved Space, Which Is Called A Geodesic. A Geodesic Is The Shortest (or Longest) Path Between Two Nearby Points.

So Long As The Universe Had A Beginning, We Could Suppose It Had A Creator. But If The Universe Is Really Completely Self-contained, It Would Have Neither Beginning Or End, It Would Simply Be. What Place Then For A Creator?

I Am Just A Child Who Has Never Grown Up. I Still Keep Asking These 'how' And 'why' Questions. Occasionally, I Find An Answer.
