#1 There Are Not 24 Hours In a Day

Ever since you were in elementary school, you were taught that there are 24 hours in a day. This is not technically true. The Earth spins on its axis for 23 hours and 56 minutes. The reason we add an extra 4 minutes is that the distance that that Earth orbits the Sun is so great that it takes extra time for us to face the Sun again. Eventually, the time will catch up and the days will last longer than 24 hours. This is because every few million years, the Earth spins slower and slower. About 250 million years from now, a typical day will last 25.5 hours. Unfortunately, we won’t be here to see that.

#2 A Glitch In the Earth’s Gravity

Hudson Bay is located in Canada. This area has an uneven mass. When there is an uneven mass, there is uneven gravity. At one time, there were glaciers in the area. Today they are melted, however, the burden of gravity still remains in ice sheets under the Earth’s crust. This has caused the gravity in Hudson Bay to be lower than anywhere else on Earth. If you are planning to visit Hudson Bay, don’t think that you can bounce around like you are on the moon. The difference in gravity in this area is just 0.005 percent. This amount is so small that you won’t be able to feel the reduction in the gravity.
