On his 30th birthday, a man who wishes to build a time machine is visited by a future version of himself. This future self explains to him that he should not worry about designing the time machine, as he has done it in the future. The man receives the schematics from his future self and starts building the time machine. Time passes until he finally completes the time machine. He then uses it to travel back in time to his 30th birthday, where he gives the schematics to his past self, closing the loop.

My real question is what happens if he never tells his old self ?

also- A professor travels forward in time, and reads in a physics journal about a new equation that was recently derived. He travels back to his own time, and relates it to one of his students who writes it up, and the article is published in the same journal which the professor reads in the future.

What happens if he keeps it to himself?

In traveling to the Moon, astronauts aboard the Apollo spacecraft put themselves into a slow rotation to distribute the sun's energy evenly. At the start of their trip they accelerated from no rotation to 1revolution every minute during a 12 min time interval. THe spacecrafy can be thought of as a cylindar with a diameter of 8.5m. Determin the angular acceleration and the radial and tengential components of the linear acceleration of a point on the skin of the ship 5 min after it started this acceleration.
