4. How many universes are there? String theory says 10 to the power of 500, quantum fluctuations produce 10 to the power of 10 to the power of 10 million. But does it really matter in a world ruled by quantum physics, where an observer's brain can only tell 10 to the power of 10 to the power 16 universes apart? Read more here.

5. 'SPACE ELEVATOR' the science fiction might become the reality in a very near future. Only last week, a laser-powered robotic climber has won $900,000 out of 2 million dollars prize from NASA, by climbing up the cable with an average speed around 3.7 m/s. The rest of the money left for whoever can reach the speed of 5 m/s. Read the story here.
