Check it out. Link.

“IN 1998, just after he won a share of the Nobel prize for physics, Robert Laughlin of Stanford University in California was asked how his discovery of “particles” with fractional charge, now called quasi-particles, would affect the lives of ordinary people. “It probably won’t,” he said, “unless people are concerned about how the universe works.”  Read all about it here.

Is time travel possible? Science weighs in with conflicting viewpoints. Read about researchers trying to influence the past. Then, see why other scientists say that time travel is impossible.

“Sunlight can cause asteroids to spin more quickly…showing anew just how dynamic a place our solar system can be.”
