Indians in the news - 1

Subhash Kak, Distinguished Professor of Electrical and Computer Engineering at LSU, claims to have solved what is commonly known as Einstein's twin paradox, which deals with the effects of time in the context of traveling near the speed of light.

What's the paradox, you ask:
The paradox has been described using the analogy of twins: If one twin is placed on a spacecraft traveling near the speed of light while the other twin remains earthbound, the unmoved twin would have aged dramatically compared with his interstellar sibling. That time slows on moving objects has been documented through repeated experimentation. But the paradox is the earthbound twin is the one who would be considered to be in motion -- in relation to the sibling -- and therefore should be the one aging more slowly.
