15 Amazing Science Facts

Science is an explanation of how certain things work. Perhaps a logical one, based on observations(experimental data) and mathematics. Science gives us the best feasible explanation and based upon these we have been able to achieve such advances in engineering, physical sciences, and medical sciences which have made our lives much easier. Here are 15 Facts related to Science that might amaze you.

1. There is enough DNA in the average person’s body to stretch from the sun to Pluto and back — 17 times.
2. The average human body carries ten times more bacterial cells than human cells.
3. It takes a photon up to 40,000 years to travel from the core of the sun to its surface, but only 8 minutes to travel the rest of the way to Earth.
