# Time slowing down problem

When someone moves, time slows down for him. Let, a man standing still and another moving very very very fast, this happens for an hour (as measured by the standing man). Time has moved slower for the moving man than for the still man. The fast has got less aged than the still. I've heard that length shortens for a thing when it moves. The faster it moves, length shortens more. I'm eager to know that; when a man is moving very fast while reading a book, will he comprehend the book's items faster than when he stands still while reading this same book? (I've thought neurons get smaller and impulses travelling lesser.)

• People get confuse. You should rephrase your question: Assuming inteligence is proportional to the distance between two synaps. Is the inteligence increasing for a near light speed moving spaceman? Aug 29, 2012 at 7:26
• You will achieve most enlightenment when you realize you are asking the same question as "If I swivel 30 degrees on my chair, do I get smarter, because my neurons are now closer together in terms of my old x-axis?" Oct 21, 2012 at 2:03
• Time flows at the rate of "60 seconds per minute" for all men in inertial frames
