In Special Relativity, will a moving person age slower than a stationary one? This is a question which has been tossed around for years, with very interesting results. One of the fundamental results of Albert Einstein's special theory of relativity is a phenomenon known as time dilation. Simply put, this result states that time moves more slowly for a moving object than it does for an object at rest. As Einstein put it in his original

Boeing is researching the possibilities of "antigravity" aircraft, inspired by the research of a controversial Russian scientist who has been dismissed by some as crazy.

1. Isaac Newton may have thought he was a clever clogs for coming up with his theory of gravity after that apple supposedly hit him on his 17th century head. But would he have been able to protect the apple from the magnetic forces of Earth's relentless pull?

2. No, and

It is assumed that a smooth surface is slippery while a rough surface is not. However this is not true with ice. Ice is slippery not due to its being smooth but because its melting point decreases when pressure increases. An explanation. One slips on a smoothly polished floor much more easily than on one that isn’t polished. So, shouldn’t smooth ice be much more slippery than bumpy ice? However, contrary to the expectation, a sled goes much
